Rinoplastia ultrasónica, mitos y verdades / Ultrasonic rhinoplasty, myths and truths

Introducción: : la cirugía plástica facial tiene una evolución constante en su técnica, análisis y resultados. La rinoplastia es una de las cirugías más frecuentes de cirugía plástica facial. Para esta cirugía se han empleado instrumentos de metal que cortan de la forma más adecuada posible para dejar el dorso nasal sin irregularidades, enderezar la pirámide nasal y disminuir asimetrías de huesos nasales. En la actualidad contamos con piezas de acero de uso médico quirúrgico y piezas de corte mecánico rotativo u oscilantes que permiten un corte preciso a través de macrovibraciones. Desde hace algunos años tenemos a disposición el bisturí ultrasónico que permite el corte a través de la microvibración, al tiempo que realiza hemostasia gracias al efecto de cavitación generado por el ultrasonido, con mejor calidad en los trazos de fractura deseados y menor lesión del tejido, lo que da como resultado un menor trauma y disminuye, a nivel macro, manifestaciones como sangrado, equimosis, hematomas, edema y dolor postoperatorio. Objetivo: el objetivo de este artículo es actualizar a los cirujanos de nariz interesados en conocer la tecnología ultrasónica y sus beneficios en cirugía de nariz. Discusión y conclusiones: la rinoplastia implica investigación y avance tanto en la técnica como en la anatomía y tecnología; ahora disponemos de equipos de microvibración ultrasónica relacionada con la piezoelectricidad que proporciona condiciones que mejoran tanto la calidad en los resultados como la confortabilidad para el paciente en el posoperatorio por un menor sangrado, menor inflamación, menor dolor, menor lesión de tejidos blandos y mejor calidad en los resultados.

Introduction: Facial plastic surgery has a constant evolution in its technique, analy-sis, and results. Rhinoplasty is one of the most frequent surgeries of facial plastic surgery, for this surgery metal instruments have been used since the beginning of his-tory that cut in the most appropriate way possible to leave the nasal dorsum without irregularities, straighten the nasal pyramid and reduce asymmetries of the nasal bo-nes. Nowadays we have steel parts for surgical medical use, rotary and oscillating mechanical cutting parts, which allow precise cuts through macro vibrations. For a few years, we have available the ultrasonic scalpel that allows cutting through micro vibrations while performing hemostasis thanks to the cavitation effect generated by the ultrasound, with better quality in the desired fracture stokes and fewer tissue in-juries resulting in less trauma, decreasing at the macro level the manifestations such as bleeding, ecchymosis, bruising, swelling, and post-surgery pain. Objective: The objective of this article is to update nose surgeons interested in knowing ultrasonic technology and its benefits in nose surgery. Discussion and conclusions: Rhinoplas-ty involves research and advancement in both technique anatomy and technology. We now have ultrasonic micro-vibration equipment related to piezoelectricity that provides conditions that improve both the quality of the results and the comfort of the patient in the postoperative period due to less bleeding, less inflammation, less pain, less soft tissue injury, and better-quality results.

Anatomical Conditions in Simultaneous Orthognathic Surgery and Structural Rhinoplasty. A Clinical Series / Condiciones Anatómicas en Cirugía Ortognática y Rinoplastia Estructural Simultanea. Una Seria Clínica

SUMMARY: Orthognathic surgery and rhinoplasty show synergy in terms of function and aesthetic results. The aim of this research is to analyze variables related to simultaneous orthognathic surgery and rhinoplasty and to discuss the surgical sequence. Male and female subjects between 18 and 45 years old were included in this research. Diagnosis related to nasal morphology (nasal tip bifid, rotate, square and others as well as the alae morphology and columella), facial deformity (sagittal and vertical deformity), type of surgery (rhinoplasty techniques and orthognathic techniques) and complications were included. The minimum follow-up was 12 months; Chi- Square and t test were used to define correlations, considering a value of p<0.05 for statistical significance. Class III facial deformity was observed in 40 % of subjects and class II facial deformity was present in 43 %. For the nasal deformities, the tip and nasal bridge were most prevalent; primary nasal deformity was observed in the 83 % of subjects and was significant more than secondary nasal deformity (p=0.042). Bimaxillary surgery was performed in 31 cases (88 %). In 10 cases a change of the original plan for rhinoplasty due to previous maxillary surgery was realized, mainly in class III facial deformity, with no statistical differences. Revision rhinoplasty was realized in 5 cases (14 %) and was not related to surgical variables; revision for orthognathic surgery was not necessary in this series. Rhinoplasty and orthognathic surgery simultaneously show low complications and predictable results. We can conclude that maxillary mandibular osteotomies and rhinoplasty could be performed safely. However, larger studies are necessary to understand the best choice and variables involved in simultaneous procedures and soft tissue response.

La cirugía ortognática y la rinoplastia muestran sinergia en términos de resultados funcionales y estéticos. EL objetivo de esta investigación es analizar variables relacionadas con la cirugía ortognática y rinoplastia ejecutada de forma simultanea. Fueron incluidos hombres y mujeres entre 18 y 45 años de edad. EL diagnóstico fue en base a la morfología nasal (punta bífida, rotada, cuadrada u otras así como alteraciones del ala nasal y columela), deformidad facial (deformidad sagital y vertical), tipo de cirugía (técnica de rinoplastia y cirugía ortognática) y complicaciones asociadas. El seguimiento mínimo fue de 12 meses; se utilizo las prueba t test y chi cuadrado para definir relaciones estadísticas considerando un valor de p< 0,05 para obtener diferencias significativas. La deformidad clase III fue observada en el 40 % de los sujetos y la deformidad facial de clase II se presento en el 43 %. Para la deformidad nasal, las alteraciones de a punta nasal y nasal fueron mas prevalentes; la deformidad nasal primaria se presentó en el 83 % de los sujetos y fue significativamente mayor que la deformidad nasal secundaria (p=0,042). La cirugía bimaxilar se realizó en 31 casos (88 %); en 10 casos se realizó el cambio del plan quirúrgico inicial de la rinoplastia debido a cambios generados en la cirugía maxilar previa, mayormente en deformidad facial de clase III, sin presentar diferencias significativas. La rinoplastia de revisión fue realizada en 5 casos (14 %) y no fue relacionada con ninguna variable de tipo quirúrgica; la revisión de cirugía ortognática no fue realizada en ningún caso de esta serie. La rinoplastia y la cirugía ortognática simultanea mostraron bajas complicaciones y resultados predecibles. Se puede concluir que la osteotomía maxilo mandibular y la rinoplastia son seguras; sin embargo, estudios de mayor volumen son necesarios para entender la mejor opción y variables relacionadas con procedimientos simultáneos y la respuesta de tejidos blandos faciales.

Protocol for capturing 3D facial meshes for rhinoseptoplasty planning

Abstract Objectives: To present and execute a protocol for the capture of 3D facial images using photogrammetry through the open access software Blender and its add-on OrtogOnBlender (OOB) and to evaluate the compatibility of the 3D meshes generated with Computed tomography (CT) of the sinuses. Methods: Individuals > 18 years old, candidates for Rhinoseptoplasty in a tertiary hospital, were submitted to a photographic session to perform the standardized protocol. In the session, divided into 3 phases, sequential photos were taken for processing the photogrammetry in the OOB and producing 3D meshes of the face. The photogrammetry reconstructions were compared with the reference mesh of the soft tissue surface of the Sinus CT scan to assess compatibility between them. Results: 21 patients were included, 67% female. 3 photogrammetry meshes and 1 CT reference mesh were generated, which demonstrated matching compatibility, as most of the mean distances between cloud points were <1.48mm. Phase 3 of the session with the highest number of photos (54.36 ± 15.05) generated the most satisfactory mesh with the best resolution. Conclusions: The proposed protocol is reproducible and feasible in clinical practice, generated satisfactory 3D meshes of the face, being a potential tool for surgical planning and comparison of results. For the implementation of photogrammetry for use in 3D anthropometry, it is necessary to validate this method. Level of evidence: 3.

Comparative Evaluation of Postoperative Pain Scores and Opioid Consumption in Septorhinoplasty After Administration of Single-Dose Preemptive Paracetamol and Ibuprofen: A Randomized Controlled Trial

Abstract Introduction Septorhinoplasty operates on the nose's bone and cartilage and is ensued by severe postoperative pain. Objective The objective of this study is to evaluate the effects of preoperative administration of intravenous (IV) paracetamol and ibuprofen on postoperative pain scores in patients undergoing septorhinoplasty. Methods A total of 150 patients undergoing septorhinoplasty were randomly assigned into 3 groups with 50 patients in each group. The control group (group A) was administered 100 ml saline solution; the paracetamol group (group B) was administered 1,000 mg of IV paracetamol in 100 ml of saline solution; and the ibuprofen group (group C) was administered 800 mg of IV ibuprofen in 100 ml of saline solution before surgery. Opioid analgesics were employed to achieve postoperative analgesia. Postoperative pain was evaluated using the visual analogue scale (VAS). Postoperative opioid consumption and adverse effects were also recorded for each patient. Results In comparison with group A, the score in the VAS of groups B and C was statistically lower in all the time intervals (p < 0.05). In the 1st and 6th hours postoperatively, group C's score in the VAS in was lower than that of group B (p < 0.05). In the control group, total opioid consumption was highest in all time intervals (p < 0.05). In group C, total opioid consumption was significantly lower than in group B in the 0 to 6 and 6 to 12 hours intervals. (p < 0.05). Conclusion The single-dose preemptive administration of ibuprofen has a more profound postoperative analgesic effect than paracetamol in the first 6 hours after septorhinoplasty. After the first 6 hours postsurgery, there is no difference between ibuprofen and paracetamol in terms of analgesic effect.

Percepção da redução do tamanho após rinoplastia de aumento não cirúrgica: Análise retrospectiva de 116 casos / Perception of size reduction after non-surgical augmentation rhinoplasty: Retrospective analysis of 116 cases

Introdução: Tradicionalmente, o rebaixamento do dorso é o único método de correção da giba. Raras séries apontam a elevação do radix como possível solução. O que explica essa maciça predominância do procedimento redutor? Ineficácia dos métodos de aumento de radix e ponta? Percepção de nariz grande com os procedimentos de aumento? Nossos objetivos são descobrir se a percepção de redução ocorre na rinoplastia não cirúrgica (RNC), feita exclusivamente com adição de volume, e se a percepção de redução é importante na RNC. Método: Análise retrospectiva de 116 pacientes consecutivos submetidos a RNC. As imagens dos pacientes foram analisadas por 12 observadores independentes que avaliaram as mudanças percebidas no tamanho do nariz e a qualidade da correção, dando notas de 1 a 10 para os dois quesitos. Quanto ao tamanho, 1 representava muito menor que antes, 5 mesmo tamanho (neutralidade) e 10 muito maior que antes. A qualidade da correção foi classificada de 1 a 10. Resultados: 92 casos (79%) foram percebidos como redução do tamanho, enquanto 20 casos (17%) foram percebidos como aumento. Houve percepção de redução na média das pontuações de tamanho (4,71). A média da qualidade da correção foi de 8,28 na escala de 1 a 10. Ademais, nossos resultados sugerem que pode haver correlação indireta entre a percepção do tamanho e a qualidade da correção. Conclusão: O aumento proporcionado pela RNC pode causar percepção de redução do tamanho do nariz, e o grau da redução percebida pode estar diretamente relacionado ao grau de qualidade percebida da correção.

Introduction: Traditionally, lowering the dorsum is the only method of hump correction. Rare series point to raising the radix as a possible solution. What explains this massive predominance of the reduction procedure? Ineffectiveness of radix and tip augmentation methods? Big nose perception with augmentation procedures? Our objectives are to determine if the perception of reduction occurs in non-surgical rhinoplasty (NSR), performed exclusively with volume addition, and if the perception of reduction is important in NSR. Method: Retrospective analysis of 116 consecutive patients undergoing NSR. The patients' images were analyzed by 12 independent observers who evaluated the perceived changes in the nose's size and the correction's quality, giving scores from 1 to 10 for both questions. As for size, 1 represented much smaller than before, 5 same size (neutrality), and 10 much larger than before. The quality of correction was graded from 1 to 10. Results: 92 cases (79%) were considered size reduction, while 20 cases (17%) were considered enlargement. There was a perception of a reduction in the average size scores (4.71). The mean correction quality was 8.28 on a scale of 1 to 10. Furthermore, our results suggest that there may be an indirect correlation between perceived size and correction quality. Conclusion: The increase provided by the NSR can cause a perception of a reduction in the size of the nose, and the degree of perceived reduction can be directly related to the degree of perceived quality of the correction.

Evaluación clínica para el aumento del mentón en pacientes sometidos a rinoplastia / Clinical evaluation for chin augmentation in patients undergoing rhinoplasty

Introducción: el análisis detallado de las proporciones nasofaciales desempeña un papel fundamental para lograr la armonía facial e identificar desequilibrios; asi se dirige el tratamiento quirúrgico para lograr mejores resultados postoperatorios. El objetivo de este estudio fue determinar la prevalencia de pacientes sometidos a rinoplastia que requerían, además, un aumento del mentón. Materiales y métodos: se seleccionaron 100 pacientes voluntarios sometidos a rinoplastia entre los 17 y 55 años y se les realizó un estudio fotográfico preoperatorio. Se realizó un análisis facial del tercio inferior de la cara mediante tres métodos: González-Ulloa, Goode y Silver, y se hizo un análisis univariado y bivariado. Resultados: 100 pacientes voluntarios ingresaron al estudio; de estos, 7 fueron excluidos y quedaron 73 mujeres y 20 hombres; la edad mínima fue de 17 años y la máxima de 55 años, con un promedio de 28,4 años. La edad media de los hombres fue de 30,9 años y de las mujeres de 28,2 años. Del total de pacientes, 96,7 % de los pacientes cumplían con 2 o 3 métodos para aumento del mentón; de estos, 78,8 % eran mujeres y 21,1 % eran hombres. Conclusión: un análisis adecuado de las proporciones nasofaciales es fundamental para determinar los procedimientos necesarios para lograr un buen resultado quirúrgico y una mayor satisfacción del paciente. Estos métodos no sustituyen el juicio estético del cirujano; sin embargo, proporcionan un estándar objetivo para el diagnóstico de los desequilibrios faciales.

Introduction: Detailed analysis of nasofacial proportions plays a fundamental role in achieving facial harmony and identifying imbalances; thus, surgical treatment is directed to achieve better postoperative outcomes. The aim of this study was to determine the prevalence of patients undergoing rhinoplasty who also required chin augmentation. Materials and methods: 100 volunteer rhinoplasty patients between 17 and 55 years of age were selected and a preoperative photographic study was performed. Facial analysis of the lower third of the face was performed by three methods: Gonzalez-Ulloa, Goode and Silver, univariate and bivariate analysis was performed. Results: 100 voluntary patients entered the study, 7 of these were excluded, leaving 73 women and 20 men, the minimum age was 17 years and the maximum 55 years, with an average of 28.4 years. The mean age of the men was 30.9 years and of the women 28.2 years. Of the total number of patients, 96.7% of the patients com- plied with 2 or 3 methods for chin augmentation, of these 78.8% were women and 21.1% men. Conclusions: Adequate analysis of nasofacial proportions is essential to determine the procedures necessary to achieve a good surgical outcome and greater patient satisfaction. These methods do not replace the surgeon's aesthetic judgment; however, they provide an objective standard for the diagnosis of facial imbalances.

Medidas para optimizar cuidados post rinoplastia. Revisión sistemática de la literatura / Measures to optimize rhinoplasty post operative care, systematic review of the literature

Introducción: El cuidado postoperatorio de la rinoplastia ha evolucionado, paralelamente, al desarrollo de la técnica quirúrgica. Existen varias recomendaciones, sin embargo, hay una gran variabilidad interprofesional de las indicaciones post quirúrgicas. Objetivo: Realizar una revisión sistemática de la literatura científica sobre los cuidados post operatorios de la rinoplastia. Material y Método: Para la realización de este estudio se llevaron a cabo búsquedas en PubMed y en Cochrane Database of Systematic Reviews con los perfiles: ([rhinoplasty] AND [post operative care]) y ([rhinoplasty] AND [post surgical care]). Se seleccionaron los artículos publicados en los últimos 10 años, desde 2013 hasta 2023, ambos inclusive. Resultados: Los documentos analizados recogen la evidencia de los diferentes métodos de cuidados post quirúrgicos en rinoplastia. Estos confirman la utilización de corticoides en el período postoperatorio, así como el reposo en 90° y exponen la variabilidad interprofesional que existe en el protocolo postquirúrgico de esta cirugía. Conclusión: El uso de corticoides y el reposo en 90° disminuyen las complicaciones postquirúrgicas de la rinoplastia. Debe existir una clara información sobre lo que el paciente debe esperar post cirugía. El uso de opioides debe ser restringido y la analgesia debe ser multimodal. Es preciso realizar estudios futuros con mayor nivel de evidencia y tener protocolos uniformes para la práctica clínica.

Introduction: The postoperative care of rhinoplasty has evolved along with the development of the surgical technique. There are several recommendations, however there is enormous interprofessional variability of post-surgical indications. Aim: To carry out a systematic review of the scientific literature on rhinoplasty postoperative care. Material and Method: To carry out this study, searches were carried out in PubMed and in the Cochrane Database of Systematic Reviews with the profiles: ([rhinoplasty] AND [post operative care]) and ([rhinoplasty] AND [post surgical care]). Articles published in the last 10 years were selected, from 2013 to 2023, both inclusive. Results: The documents analyzed collect the evidence of the different methods of post-surgical care in rhinoplasty, they confirm the use of corticosteroids in the postoperative period as well as rest at 90° and expose the interprofessional variability that exists in the post-surgical protocol of this surgery. Conclusion: The use of corticosteroids and rest at 90° reduce the post-surgical complications of rhinoplasty. There must be clear information about what the patient should expect post surgery. The use of opioids must be restricted and analgesia must be multimodal. It is necessary to carry out future studies with a higher level of evidence and have uniform protocols for clinical practice.

Evaluation of the Results of Septum Extension Batten Graft in Patients Referred for Septorhinoplasty

Abstract Introduction Correction of caudal septal deviations has always been a challenging subject in septorhinoplasty. The septum batten extension graft (SBEG) is a new graft that has potential properties in rhinoplasty. However, few reports have evaluated the surgical outcomes of this technique. Objective The purpose of this study was to evaluate the effectiveness of SBEG in correcting caudal septal deviation. Methods This cross-sectional study was conducted on patients with caudal septal deviation undergoing septorhinoplasty using SBEG at 2 different hospitals in 2019. We then retrospectively reviewed medical records and photographs of 50 patients at the preoperative period, as well as at 1-month, and 12-month postoperatively. Gross changes in nasolabial angle, columellar show, nasal tip projection, and dorsal nasal deviation were evaluated by a photographic analysis method, and nasal obstruction was assessed by patient satisfaction with breathing. Results There was a significant difference between the mean nasolabial angle and columellar show at 1 and 12-months postoperatively, compared with the previous values (p < 0.0001). The nasolabial angles were in a favorable position with an increase of 12 to 15 degrees compared with the preoperative state. The columellar show also improved by an average of 1.2 mm and was in good condition. The postoperative dorsal nasal deviation was significantly reduced, and projection was significantly increased (3.521 ± 0.087 mm vs. 0.719 ± 0.028; p < 0.0001; p < 0.001 ). Moreover, this method had a significant favorable effect on nasal obstruction (p = 0.049). Conclusion Our results showed that septorhinoplasty using SBEG is useful for correcting caudal septal deviation, with favorable surgical outcomes, and it has responded well to all five aforementioned criteria.

Rinoplastia en nariz mestiza, un desafío quirúrgico / Rhinoplasty in mestizo nose, a surgical challenge

Las características anatómicas de pacientes con nariz mestiza, generalmente, incluyen una nariz aparentemente grande, un dorso convexo con radix bajo y una base nasal ancha. La longitud de la columela y punta nasal se ve disminuida debido a que los cartílagos alares son cortos, débiles y delgados, proporcionando un soporte estructural insuficiente, mala definición y proyección de la punta nasal. La principal dificultad al manejar este tipo de narices es un marco osteocartilaginoso mal estructurado y débil. En los últimos años se han desarrollado técnicas quirúrgicas para mejorar los resultados estéticos y funcionales de la rinoplastía en estos pacientes. Se realizó una revisión exhaustiva de la literatura describiendo las técnicas quirúrgicas utilizadas en este tipo de nariz.

The anatomical characteristics of patients with mestizo nose usually include an apparently large nose, a convex dorsum with a deep radix, and a wide nasal base. The length of the nasal columella and tip is decreased because the alar cartilages are short, weak and thin, providing insufficient structural support, poor definition and nasal tip projection. The main difficulty in managing this type of noses is a poorly structured and weak osteocartilaginous framework. In recent years, surgical techniques have been developed to improve the aesthetic and functional results of rhinoplasty in these patients. A comprehensive literature review was conducted describing the surgical techniques used in this type of nose.

Effects of costal cartilage cortex on nasal tip contour improvement / 中华医学美学美容杂志

Objective:To investigate the effect of autologous costal cartilage cortex as nasal tip support and modified graft for nasal tip contour improvement.Methods:From June 2020 to June 2021, 116 patients (male 26, female 90, aged 20-45 years) who received rhinoplasty in the cosmetic surgery department of Myoung Beaucare Clinic of Beijing, were examined the costal cartilage by CT, and the costal cartilage was cut. The costal cartilage cortex was made into " strip" and " cap" grafts to shape the nasal tip, and the nasal dorsum was raised by polytetrafluoroethylene or silicone prosthesis for comprehensive rhinoplasty.Results:A total of 116 patients were followed up for an average of 11.7 months. After the operation, there was no space occupying in the nasal cavity, no graft protrusion, no obvious foreign body feeling in the nasal valve, and the nasal tip could swing left and right. At the same time, the nasal tip showed obvious signs, the lower lobule was full, and there were no complications such as cartilage appearance, exposure, infection, etc. Due to the untreated deviation of nasal septum, 3 cases had deviation of nasal columella and asymmetric nostrils. The shape of nasal tip was stable in the remaining 113 cases, and satisfactory results were obtained.Conclusions:By using autologous costal cartilage cortex as nasal tip support and modification graft for nasal tip contour improvement, the shaped nasal tip is soft and movable, and does not affect the airway. It is a good surgical technique in nasal tip plastic surgery, which is worthy of clinical application.

Application of nasal aesthetic polygon theory in reconstruction of new domes by costal cartilage on nasal tip / 中华医学美学美容杂志

Objective:To explore the application of nasal aesthetic polygon theory in the reconstruction of new domes on nasal tip with autogenous costal cartilage.Methods:From June 2019 to June 2021, 116 patients (26 males and 90 females) received rhinoplasty, CT-assisted examination of the costal cartilage, nasal bone and nasal cartilage was performed, and the autogenous costal cartilaginous cortex was used to make dome reconstruction grafts that were transplanted to the original alar cartilage and partially fixed to the original nasal septum cartilage to form a satisfactory and natural nasal shape.Results:All the patients were followed up for 6-24 months. No cartilaginous, overrotated or underrotated appearance was found in nasal tip. The shape of nasal tip was clear and good, with an obvious performance point and full lower lobule. The nose was tall and straight, and looked natural and beautiful in three dimensions.Conclusions:The nasal aesthetic polygon theory is used to guide the reconstruction of new domes with autogenous costal cartilage in nasal tip surgery. Compared to the cap and shield grafts, the nasal tip is more close to the normal anatomical structure, the shape and texture are more similiar to the natural state and the nasal tip is softer by using autogenous costal cartilage, and so it is an ideal surgical procedure for nasal tip reconstruction.

Effects of a special shaped tip cartilage support structure on alar rim retraction / 中华医学美学美容杂志

Objective:To investigate the clinical effectiveness and significance of special fixing cartilaginous support structure on nasal tip to prevent and correct alar rim retraction.Methods:Special shaped tip extension support structure was composed of two parts of type Ⅲ of septum extension graft (SEG) and two pieces of wedge graft fixed on either side of the cephalic end near the top of support structure. After the alar cartilage vault was fixed to the nasal tip cartilage support structure, the lower lateral cartilage (LLC) cephalic was fixed to both sides of this nasal tip support structure. The LLC received support from the cartilaginous support structure to counter and correct the lower lateral cartilage cephalic retraction. From January 2017 to January 2020, this surgical procedure was used in 34 patients (aged from 20 to 46 years, with mean 32.6 years) with rhinoplasty who had a nasal tip support structure but still had a space between the LLC and the stent intraoperativly. Preoperativly, 4 cases had normal relation of alar columella and alar rim, 18 cases had mild alar rim retraction, and 12 cases had moderate alar rim retraction. The patients were followed up for 6 to 18 months to observe the correction effect and patient satisfaction.Results:Among the 34 patients, 8 patients received alar edge graft, 2 patients received lateral foot support graft, and 2 patients received alar rim graft combined with lateral foot support graft. All patients were followed up for 6-18 months, 30 patients with alar rim retraction were completely corrected, and 4 patients with normal alar and nasal columella relationship did not have alar rim retraction after surgery. No complications such as infection, necrosis, contracture or respiratory dysfunction were found in all patients. 28 cases (82.4%) were very satisfied; 6 cases (17.6%) were satisfied; the satisfactory rate was 100%.Conclusions:The special shaped nasal tip cartilage support structure combined with type Ⅲ SEG and its cephalic wedge grafts could achieve satisfactory clinical results in the prevention and correction of alar rim retraction.

Rinoplastia cerrada: una técnica vigente / Closed Rhinoplasty: a current technique

La rinoplastia cerrada es una cirugía que se realiza con el fin de cambiar la estructura de la nariz, con fines cosméticos o reparadores. Se busca realizar pequeños retoques que logren un aspecto natural. Es una de las cirugías estéticas más complejas y representa un reto para el cirujano, pues combina técnica con sensibilidad y ciencia con arte. En este artículo describimos esta técnica con el objetivo de demostrar su eficacia y vigencia, sin compararla con la rinoplastia abierta, pues no es motivo de discusión en este trabajo, por lo que no podemos asegurar que una opción es mejor o peor que la otra. Lo más conveniente es que los cirujanos estén capacitados para realizar cualquiera de estas. Con la rinoplastia cerrada se logran resultados que llenan las expectativas tanto de los pacientes, como de los cirujanos y el post operatorio es breve y prácticamente sin incidentes. Es una propuesta que tiene indicaciones precisas en el marco de una rinoplastia preservadora, que es tendencia a nivel mundial en la actualidad.

Closed rhinoplasty is a surgery that is performed in order to change the structure of the nose, for cosmetic or restorative purposes. It seeks to make small touches that achieve a natural appearance. It is one of the most complex cosmetic surgeries and represents a challenge for the surgeon, as it combines technique with sensitivity and science with art. In this article, we describe this technique in order to demonstrate its effectiveness and validity, without comparing it with open rhinoplasty, since it is not a matter of discussion in this work, so we cannot guarantee that one option is better or worse than the other. It is best if surgeons are trained to perform any of these. With closed rhinoplasty, results are achieved that meet the expectations of both patients and surgeons, and the postoperative period is brief and practically uneventful. It is a proposal that has precise indications within the framework of conservative rhinoplasty, which is currently a worldwide trend.

Comparison of scar outcomes of alar flare region using absorbable and non-absorbable sutures: a single-blind study

Abstract Objective: Formation of scar on the face after septorhinoplasty may disturb the patient due to cosmetic concerns. One of the main factors affecting scar outcomes is probably the suture material used. The aim of this study was to examine the effect of different suture materials on scar outcomes of alar base in patients undergoing septorhinoplasty. Methods: Thirty-one patients who underwent alar base intervention during primary septorhinoplasty were divided into two groups according to the suture material used as the Polypropylene group (n = 16), (Polypropylene, Prolene 6/0; Ethicon Inc., Somerville, NJ, USA) and the Polyglactin group (n = 15), (Irradiated polyglactin 911, Vicryl RapidTM 6/0; Ethicon Inc., Somerville, NJ, USA). The scar outcomes of alar base were compared between the Polypropylene and Polyglactin groups. The modified Stony Brook Scar Evaluation Scale was used to measure wound healing results at one and 12-months postoperatively for objective evaluation. Patient satisfaction questionnaire was used for subjective evaluation. Results: There were no statistically significant differences in the Stony Brook Scar Evaluation Scale and patient questionnaire scores between Polypropylene and Polyglactin groups. Irradiated Vicryl Rapid had poor cosmetic outcomes in the alar base when compared to polypropylene, indicating no statistically significant difference. Conclusion: Both sutures can be used for closure of alar base considering their advantages and disadvantages, in patients undergoing septorhinoplasty. Level of evidence: Treatment Benefits; Level 2 (Randomized Trial).

Evaluation of postoperative satisfaction with rhinoseptoplasty in patients with symptoms of body dysmorphic disorder / Avaliação da satisfação pós-operatória da rinosseptoplastia em pacientes com sintomas de transtorno dismórfico corporal

Abstract Introduction: The prevalence of body dysmorphic disorder among candidates for plastic surgery may vary from 6% to 54%. Some studies report discrete benefits with the surgical results, while others show symptomatic exacerbation. Some authors even affirm that body dysmorphic disorder would be a surgical contraindication, against others who suggest satisfactory results. Objective: To describe the prevalence of body dysmorphic disorder in rhinoseptoplasty candidates and to compare outcomes among patients with and without body dysmorphic disorder symptoms. Methods: Cohort study. Individuals ≥ 16 years, candidates for aesthetic and/or functional rhinoseptoplasty were recruited at a university hospital in Brazil. The prevalence of body dysmorphic disorder was assessed through the Body Dysmorphic Disorder Examination (BDDE) and the patients divided into groups: no symptoms of body dysmorphic disorder, mild-moderate and severe symptoms. The specific quality of life outcomes, Nasal Obstruction Symptom Evaluation (NOSE) and Rhinoplasty Outcome Evaluation (ROE) were evaluated before and after 90 and 180 days of the procedure. Results: 131 individuals were included, 59.5% female. The prevalence of preoperative symptoms of body dysmorphic disorder was 38%. There was a reduction in the symptoms of body dysmorphic disorder in the preoperative body dysmorphic disorder examination versus 3 and 6 months in all groups (78.94 ± 2.46 vs. 33.63 ± 6.41 and 35.51 ± 5.92, respectively, p < 0.002). Among patients with severe body dysmorphic disorder symptoms, rhinoplasty outcome evaluation ranged from 21.24 ± 3.88 to 58.59 ± 5.83 at 3 months and 52.02 ± 5.41 at 6 months postoperatively (p < 0.001); while NOSE from 71 ± 8.47 to 36.11 ± 12.10 at 6 months postoperatively (p <0.01). Conclusion: The prevalence of body dysmorphic disorder symptoms in our sample was high. Rhinoseptoplasty was associated with an improvement in quality of life outcomes related to nasal function and aesthetic outcome in all groups, irrespective of the presence and intensity of body dysmorphic disorder symptoms. Rhinoseptoplasty in body dysmorphic disorder symptomatic patients was also associated with a reduction in postoperative body dysmorphic disorder symptoms, even in severe cases.

Resumo Introdução: A prevalência do transtorno dismórfico corporal entre os candidatos à cirurgia plástica pode variar de 6% a 54%. Alguns estudos relatam benefícios discretos com os resultados cirúrgicos, enquanto outros mostram exacerbação dos sintomas. Alguns autores chegam a afirmar que o transtorno dismórfico corporal seria uma contraindicação cirúrgica, contra outros que sugerem resultados satisfatórios. Objetivo: Descrever a prevalência do transtorno dismórfico corporal em candidatos à rinosseptoplastia e comparar os desfechos entre pacientes com e sem sintomas de transtorno dismórfico corporal. Método: Estudo de coorte. Indivíduos ≥ 16 anos, candidatos à rinosseptoplastia estética e/ou funcional, foram recrutados em um hospital universitário no Brasil. A prevalência de transtorno dismórfico corporal foi avaliada por meio do questionário body dysmorphic disorder examination e os pacientes foram divididos nos grupos: sem sintomas de transtorno dismórfico corporal, sintomas leves-moderados e sintomas graves. Os resultados específicos da avaliação de qualidade de vida, com os instrumentos nasal obstruction symptom evaluation, NOSE, e rhinoplasty outcome evaluation, foram avaliados antes, após 90 e 180 dias do procedimento. Resultados: Foram incluídos 131 indivíduos, 59,5% do sexo feminino. A prevalência de sintomas pré-operatórios de transtorno dismórfico corporal foi de 38%. Houve redução dos sintomas de transtorno dismórfico corporal no body dysmorphic disorder examination pré-operatório vs. 3 e 6 meses em todos os grupos (78,94 ± 2,46 vs. 33,63 ± 6,41 e 35,51 ± 5,92, respectivamente, p < 0,002). Entre os pacientes com sintomas graves de transtorno dismórfico corporal, o escore do instrumento rhinoplasty outcome evaluation variou de 21,24 ± 3,88 a 58,59 ± 5,83 em 3 meses e 52,02 ± 5,41 em 6 meses de pós-operatório (p < 0,001); enquanto o escore do NOSE variou de 71 ± 8,47 a 36,11 ± 12,10 aos 6 meses de pós-operatório (p < 0,01). Conclusão: A prevalência de sintomas de transtorno dismórfico corporal em nossa amostra foi alta. A rinosseptoplastia foi associada a uma melhoria nos desfechos de qualidade de vida relacionados à função nasal e estética em todos os grupos, independentemente da presença e intensidade dos sintomas do transtorno dismórfico corporal. A rinosseptoplastia em pacientes com transtorno dismórfico corporal sintomático também foi associada à redução dos sintomas do transtorno dismórfico corporal no pós-operatório, mesmo em casos graves.

Thresholds of Identification and Aesthetic Perception of Simulated Alar Base Widening Among Oral and Maxillofacial Surgeons: an Online Questionnaire-Based International Study / Limiares de Identificação e Percepção Estética do Alargamento Simulado da Base Alar Entre Cirurgiões Buco-Maxilo-Faciais: um Levantamento Internacional

This study aimed to compare the thresholds of identification and aesthetic perception of simulated alar base widening among oral and maxillofacial (OMF) surgeons from Brazil and other countries through an online data collection form. Photographs of one male and one female model were digitally manipulated to obtain aesthetically acceptable, symmetrical faces and to gradually widen the alar base to produce six different images from each original photograph. The online questionnaire was sent to OMF surgeons of different nationalities. The results mshowed that the majority of Brazilian (88%) and international (89%) evaluators considered the female faces with 0 to 2 mm of alar base widening as being more pleasant. In turn, Brazilian (93%) and international (94%) respondents agreed that faces with the greatest widening (8 and 10 mm) were less pleasant. As for the male model, Brazilian (93%) and international (85%) OMF surgeons agreed that faces with none or small widening (0 and 2 mm) were more pleasant. The male face with the greatest widening (10 mm) was considered the least attractive by the respondents (93% in both groups). The findings of this study suggest that alar base widening up to the limit of 2 mm did not alter the perception of facial attractiveness. Thus, faces without alar base widening were considered the most attractive, while those with significant alterations were considered less attractive. Most importantly, despite the limitations of this study design, it seems that different cultural and professional contexts have minor influence on aesthetics analysis performed by OMF surgeons. (AU)

Este estudo teve como objetivo comparar os limiares de identificação e percepção estética do alargamento simulado da base alar entre cirurgiões bucomaxilofaciais (BMF) do Brasil e de outros países por meio de um formulário de coleta de dados online. Fotografias de um modelo masculino e de uma modelo feminina foram manipuladas digitalmente para obter faces esteticamente aceitáveis e simétricas e para ampliar gradualmente a base alar produzindo seis imagens diferentes de cada fotografia original. O questionário online foi enviado aos cirurgiões BMF de diferentes nacionalidades. Os resultados mostraram que a maioria dos avaliadores brasileiros (88%) e internacionais (89%) consideraram as faces femininas com 0 a 2 mm de alargamento da base alar como mais agradáveis. Por sua vez, os entrevistados brasileiros (93%) e internacionais (94%) concordaram que os rostos com maior alargamento (8 e 10 mm) foram os menos agradáveis. Quanto ao modelo masculino, os cirurgiões brasileiros (93%) e internacionais (85%) da OMF concordaram que faces com nenhum ou pequeno alargamento (0 e 2 mm) eram mais agradáveis. A face masculina com maior alargamento (10 mm) foi considerada a menos atraente pelos entrevistados (93% em ambos os grupos). Nossos achados sugerem que o alargamento da base alar até o limite de 2 mm não alterou a percepção da atratividade facial. Assim, rostos sem alargamento da base alar foram considerados os mais atraentes, enquanto aqueles com alterações significativas foram considerados menos atraentes. Mais importante ainda, apesar das limitações, parece que diferentes contextos culturais e profissionais têm pouca influência na análise estética realizada pelos cirurgiões da OMF. (AU)

Posicionamento ideal das cartilagens laterais inferiores associado à otimização da válvula nasal externa / Ideal positioning of the lower lateral cartilages associated with the optimization of the external nasal valve

Introdução: O posicionamento das Cartilagens Laterais Inferiores (CLI) está diretamente relacionado à boa funcionalidade nasal. Quando essas cartilagens apresentam um mau posicionamento cefálico, a parede lateral da válvula nasal externa fica sem suporte adequado, podendo levar à insuficiência valvular. O objetivo é definir qual o posicionamento anatômico ideal das CLI associado à otimização da válvula nasal externa. Métodos: Revisão de literatura narrativa nas seguintes bases de dados: SciELO, LILACS e Medline. Os descritores utilizados foram: "cartilagens nasais"; "obstrução nasal" e "rinoplastia", sendo selecionados 15 artigos essenciais para o entendimento do assunto. Revisão de literatura: O posicionamento do ramo lateral das CLI forma o contorno da ponta nasal e dá estabilidade à parede lateral da válvula nasal externa. Constantian definiu que o posicionamento ideal do ramo lateral das CLI à margem da asa nasal deve ser 45° ou menos. Para Toriumi, o ângulo é mensurado a partir do ramo lateral das CLI em relação ao plano sagital mediano e o valor adequado é de aproximadamente 45°. Para Silva, o posicionamento das CLI é mensurado pelo ângulo de divergência entre as CLI e tem como valor apropriado aproximadamente 90°. Conclusão: A válvula nasal externa apresenta melhor funcionamento quando as CLI estão bem posicionadas, a saber: o ângulo formado entre a borda lateral das CLI e a margem alar é próximo de 45° ou menos; o ângulo formado entre as CLI e o plano sagital mediano é próximo de 45°; o ângulo de divergência formado entre as CLI é próximo a 90°.

Introduction: The Lower Lateral Cartilages (LLC) positioning is directly related to good nasal functionality. When these cartilages have cephalic malpositioning, the lateral wall of the external nasal valve is not adequately supported, which can lead to valvular insufficiency. The objective is to define the ideal anatomical positioning of the LLC associated with optimizing the external nasal valve. Methods: Review narrative literature in the following databases: SciELO, LILACS and Medline. The descriptors used were: "nasal cartilages,"; "nasal obstruction," and "rhinoplasty," being selected 15 essential articles for the understanding of the subject. Literature review: Positioning the lateral crura of the LLC forms the contour of the nasal tip and provides stability to the lateral wall of the external nasal valve. Constantian defined the ideal positioning of the lateral crura of the LLC at the margin of the nasal alae should be 45° or less. For Toriumi, the angle is measured from the lateral crura of the LLC concerning the midsagittal plane, and the appropriate value is approximately 45°. For Silva, the positioning of the LLC is measured by the angle of divergence between the LLCs, and its appropriate value is approximately 90°. Conclusion: The external nasal valve works better when the LLCs are well-positioned, namely: the angle formed between the lateral edge of the LLCs and the alar margin is close to 45° or less; the angle formed between the LLC and the midsagittal plane is close to 45°; the divergence angle formed between the LLC is close to 90°.

Modificaciones de la punta nasal posterior a rinoplastia transcartilaginosa / Modifications of Nasal Tip After Transcartilaginous Rhinoplasty

Introducción: La reducción del ancho y definición de la punta nasal es uno de los objetivos principales de la rinoplastia estética. La vía endonasal, con incisión transcartilaginosa, se emplea principalmente cuando no hay alteraciones significativas en la estructura cartilaginosa de la punta nasal. Objetivo: Determinar los cambios morfológicos que se producen en la punta nasal, posterior a la rinoplastia transcartilaginosa. Métodos: Se realizó un estudio descriptivo, prospectivo, longitudinal en 15 pacientes con deformidad estética de la punta nasal, operados por rinoplastia transcartilaginosa en el Hospital "Hermanos Ameijeiras", entre el 2016 y el 2020. Las variables estudiadas fueron: ángulo nasolabial, ancho de la punta nasal, porciento de reducción del ancho de la punta nasal, relación longitud nasal-proyección de la punta nasal y estado de satisfacción de los pacientes. Resultados: Se produjo un estrechamiento de la punta nasal, de una media del ancho preoperatorio de 64,8 por ciento con relación a la base nasal, a una media del 60,1 por ciento para el posoperatorio, para una media del porciento de reducción del ancho de la punta nasal posoperatoria de 7,3 por ciento. En el resto de las variables estudiadas, aun cuando existieron cambios individuales, como grupo no hubo variación respecto al predominio de las categorías ideales. Conclusiones: Se produjeron modificaciones posoperatorias que tributaron en un refinamiento de la punta nasal, con un alto grado de satisfacción de los pacientes operados. Palabras clave: rinoplastia endonasal; modificación de la punta nasal; mediciones antropométricas(AU)

Introduction: The reduction of the width and definition of the nasal tip is one of the main objectives of aesthetic rhinoplasty. The endonasal route, with a transcartilaginous incision, is mainly used when there are no significant alterations in the cartilaginous structure of the nasal tip. Objective: To determine the morphological changes that occur in the nasal tip after transcartilaginous rhinoplasty. Methods: A descriptive, prospective, longitudinal study was carried out in 15 patients with aesthetic deformity of the nasal tip, who were operated by transcartilaginous rhinoplasty at Hermanos Ameijeiras Hospital, from 2016 to 2020. The variables studied were nasolabial angle, width of the nasal tip, percentage of reduction in the width of the nasal tip, relationship between the nasal length and the projection of the nasal tip, and the patients' satisfaction status. Results: There was a narrowing of the nasal tip, starting from a preoperative mean width of 64.8 percent in relation to the nasal base, to a postoperative mean of 60.1 percent, resulting in a mean percentage reduction in width of the postoperative nasal tip of 7.3 percent. No variation was observed regarding the predominance of the ideal categories in the rest of the variables studied, even when there were individual changes, as a group. Conclusions: Postoperative modifications were produced that contributed to a refinement of the nasal tip, with a high degree of satisfaction of the operated patients(AU)

Rinoplastia de preservación dorsal, una nueva filosofía: Experiencia en el Hospital Naval Almirante Nef / Dorsal preservation rhynoplasty, a new philosophy: Experience in the Almirante Nef Naval Hospital

Resumen Introducción: La rinoplastia de preservación dorsal es una técnica innovadora en rinoplastias de reducción primaria, logrando una adecuada ventilación nasal y resultados estéticos naturales. Objetivo: Describir los resultados estéticos y funcionales en pacientes sometidos a rinoplastias de preservación dorsal. Material y Método: Se realiza un estudio de intervención no aleatorio "antes-después", donde se evaluaron las variables estética y funcional previo a la cirugía y luego a los seis meses. La variable estética se evaluó mediante el cuestionario de Utrecht (CU), escala visual análoga de apariencia nasal (EVA) y set de fotos clínicas. La variable funcional mediante el cuestionario de NOSE (Nasal Obstruction Symptoms Evaluation). Resultados: Un total de 15 pacientes fueron sometidos a rinoplastia de preservación dorsal. No hubo complicaciones tanto intra como posoperatorias. Ningún paciente intervenido presentó irregularidades dorsales, asimetrías, ni deformidades en "V" invertidas. Se observó una mejoría estadísticamente significativa (p < 0,01) en los resultados del CU, EVA y NOSE. Conclusión: La rinoplastia de preservación dorsal ofrece como resultado una nariz funcional, con líneas dorsales posoperatorias naturales. Esta técnica no presenta estigmas quirúrgicos, por lo que no es necesario la utilización de injertos para reparación del dorso nasal. Es rápida y fácil de realizar por cualquier cirujano especialista en rinoplastias.

Abstract Introduction: Dorsal preservation rhinoplasty is an innovative technique in primary reduction rhinoplasty, achieving adequate nasal ventilation and natural aesthetic results. Aim: To describe the aesthetic and functional results in patients undergoing dorsal preservation rhinoplasties. Material and Method: A non-randomized "before-after" intervention study was carried out, where the aesthetic and functional variables were evaluated before surgery and then at six months. The aesthetic variable was evaluated using the Utrecht questionnaire (CU), the visual analog scale of nasal appearance (VAS), and a set of clinical photos. The functional variable using the Nasal Obstruction Symptoms Evaluation (NOSE) questionnaire. Results: A total of 15 patients underwent dorsal preservation rhinoplasty. There were no intraoperative and postoperative complications. No patient who underwent surgery presented dorsal irregularities, asymmetries, or inverted "V" deformities. A statistically significant improvement (p < 0.01) was observed in the UC, VAS, and NOSE results. Conclusion: Dorsal preservation rhinoplasty results in a functional nose, with natural postoperative dorsal lines. This technique does not present surgical stigmata, so it is not necessary to use grafts to repair the nasal dorsum. It is quick and easy to perform by any rhinoplasty surgeon.
