ABSTRACT
Objective@#The aim of this study was to investigate the effect of changes in nasal tip protrusion on the sense of upper lip protrusion in different populations and to provide a reference for the improvement of soft tissue beauty.@*Methods @# Informed consent and portrait authorization were obtained from the model. A female model whose face met the criteria was selected, and a 3D model of her was obtained using a 3D stereo camera. Based on the original model, ZBRUSH2019 software was used to simulate changes in nose tip protrusion. Then, 9 segments of facial dynamic rotation videos were produced, and an electronic questionnaire was created through a questionnaire website to evaluate the effect of different nose tip protrusions on perceived upper lip protrusion. Randomly selected orthodontic patients, orthodontics professionals and general adults completed the electronic questionnaire. In the questionnaire, a Visual Analog Scale was used to evaluate the perceived degree of protrusion of the upper lip. The higher the score, the more prominent the upper lip of the model in the image. The questionnaire data were statistically analyzed using a generalized linear mixed model. @*Results @#As the nasal tip position became progressively more retracted, the subjects' upper lip protrusion scores increased. Among male subjects, the results showed that the general population thought that the upper lip protrusion was higher than the patients did when the nasal tip protrusion was +6 mm and +4.5 mm (P = 0.023, P = 0.047). When the nasal tip protrusion was +6 mm, the scores of the general population were higher than those of the orthodontics professionals (P = 0.023). However, when the nasal tip variable was -6 mm, their score was lower than that of the patients (P = 0.003), and there was no significant difference in other retest distances between groups (P>0.05).@*Conclusion @#When the protrusion of the nasal tip decreased, the three groups experienced a visual illusion of upper lip protrusion. When the nasal tip protrusion is too large, the general population perceived the visual illusion of the upper lip protrusion as being more obvious.
ABSTRACT
Objective@#To present a rare case of nasal tip schwannoma and describe its resection and reconstruction using combined cartilage grafts.@*Methods@#Design: Case Report Setting: Tertiary Government Training Hospital Patient: One@*Results@#A 13-year-old boy presented with a progressively enlarging nasal tip and severe left nasal obstruction causing breathing difficulties and psychosocial distress. There was a bulging septal mass obstructing 90% of the left nasal cavity. Septal incision biopsy revealed schwannoma and definitive surgery via open rhinoplasty approach was done. The non-encapsulated schwannoma extended from the subcutaneous nasal tip to the left septal mucosa. There was no evidence of skin or cartilage invasion, but prolonged pressure from the expansile schwannoma caused severe lower lateral cartilage and anterior septal atrophy leading to a collapsed and expanded nasal tip after resection. To correct this, a total reconstruction of the anterior tip complex was done using combined ear cartilage seagull wing graft, shield graft and septal extension graft. @*Conclusion@#Nasal tip and septal schwannoma is rare and can cause significant nasal obstruction and deformity. Complete excision is vital to avoid recurrence. Total reconstruction of the lower lateral cartilages using autologous septal and ear cartilage grafts may be a safe and effective technique that yields acceptable aesthetic results.

Abstract Background: Congenital heart defects (CHD) are among the most frequent manifestations of 22q11.2 deletion syndrome. Although we found relatively few studies aimed at specifically detecting 22q11.2 deletion in newborns (NB) with CHD, none of them has been performed in Mexico. Methods: We conducted a prospective hospital-based study from January 2017 to March 2021 in the Genetics and Pediatric Cardiology Services of the Hospital Civil de Guadalajara Dr. Juan I. Menchaca (Guadalajara, Mexico). All consecutive NBs identified with any non-syndromic major CHD confirmed by echocardiography were eligible to participate. A total of 98 NBs were included, 51 males and 47 females. Fluorescence in situ hybridization (FISH) analysis was conducted to search for deletion of chromosome 22q11.2 in interphase nuclei of standard lymphocyte cultures. Results: We found eight patients (8.2%) with CHD and the 22q11.2 deletion, all of them with conotruncal defects, particularly of the truncus arteriosus (p = 0.013), tetralogy of Fallot (p = 0.024), and pulmonary atresia with ventricular septal defect (p = 0.031) subtypes. With de exception of one infant with hypocalcemia and another with hypocalcemia and thymic aplasia, the diagnosis of 22q11.2 deletion was not clinically suspected in the other patients. Conclusions: Our results confirm the importance of excluding the presence of the 22q11.2 deletion in every NB with CHDs, particularly of the conotruncal subtype, even in the absence of other manifestations.
Resumen Introducción: Las cardiopatías congénitas (CC) son una de las manifestaciones más frecuentes del síndrome de deleción 22q11.2. A pesar de que existen relativamente pocos estudios dirigidos a detectar específicamente la deleción 22q11.2 en recién nacidos (RN) con CC, ninguno de ellos ha sido realizado en México. Métodos: Se realizó un estudio prospectivo de base hospitalaria desde enero de 2017 hasta marzo de 2021 en los Servicios de Genética y Cardiología Pediátrica del Hospital Civil de Guadalajara Dr. Juan I. Menchaca (Guadalajara, México). Todos los RN consecutivos identificados con cualquier tipo de CC mayor no sindrómica confirmada por ecocardiografía fueron elegibles para participar. Se incluyeron 98 recién nacidos, 51 de sexo masculino y 47 de sexo femenino. Mediante el análisis de hibridación fluorescente in situ (FISH, por sus siglas en inglés) se realizó la búsqueda de la deleción del cromosoma 22q11.2 en núcleos en interfase de cultivos de linfocitos estándar. Resultados: Se encontraron ocho pacientes (8.2%) con CC y la deleción 22q11.2, todos ellos con defectos conotruncales, particularmente de los subtipos tronco arterioso (p = 0.013), tetralogía de Fallot (p = 0.024) y atresia pulmonar con comunicación interventricular (p = 0.031). Con excepción de un lactante con hipocalcemia y otro con hipocalcemia y aplasia tímica, el diagnóstico de deleción 22q11.2 no se sospechó clínicamente en los demás pacientes. Conclusiones: Los resultados de este trabajo confirman la importancia de excluir la presencia de la deleción 22q11.2 en todos los RN con CC, particularmente del subtipo conotruncal, incluso en ausencia de otras manifestaciones.
ABSTRACT
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)

Objective:To discuss the principle and effect of augmentation rhinoplasty with auricular cartilage and expanded polytetrafluoroethylene.Methods:From January 2018 to January 2020, 161 patients (10 males and 151 females; aged from 19 to 48 years, with an average of 26 years) underwent " auricular cartilage plus expanded polytetrafluoroethylene" augmentation rhinoplasty in Nanfang Hospital of Southern Medical University. The expended polytetrafluoroethylene was carved into a willow leaf shape (I Shape) to fill the nasal dorsum, and the cartilage taking from cymba concha was constructed into an arched bridge shape for the nasal tip shaping. Pre-operative and 1-year post-operative measurements nasal length, nasal height, nasal depth, nasal columella height, nasal tip width, nasofrontal angle, nasolabial angle, survey of satisfaction and complication rate 1-2 years after operation were taken. The statistical analysis of nasal morphological indicators and nasal aesthetic indicators were employed.Results:The nose shape of 161 patients was improved to varying degree. All morphological indicators were improved, and difference was statistically significant ( P<0.05). The nasofrontal angle reached the standard in 90 cases, accounting for 55.9%; The nasolabial angle reached the standard in 143 cases, accounting for 88.8%. 2 cases had prosthesis (ePTFE) deviation and were corrected by surgical repair; 1 case had prosthesis (ePTFE) rejection and was corrected by prosthesis (ePTFE) removal surgery. Conclusions:Corresponding to the anatomical characteristics of the external nose, the prosthesis material is designed and made to correspond to the dorsum shape of the nasal stent. The shape of the alar cartilage, the prefabricated arched bridge shape of the cymba concha cartilage are used to reconstruct the nasal tip, which can effectively elevate the nasal dorsum, improve the protruding degree and rotation degree of the nasal tip, and have good long-term support. The flexibility and activity of the nasal tip are similar to the biological nose.
ABSTRACT
Objective:To investigate the surgical method and clinical outcome of using nasal septal cartilage combined with auricular cartilage for management of nasal tip shape.Methods:A clinical study was conducted from April 2014 to June 2019, in which we managed nasal tip shape with nasal septal cartilage and auricular cartilage, and these materials were used as septal extension graft, spreader graft and cap graft. In total, 622 patients (28 males, 594 females; age from 18 to 42 years, mean age 27.47 years) were assessed for eligibility.Results:The follow-up period was from 6 months to 6 years. Nasal shape of all 622 patients was improved significantly after the operation. The nasal tip was natural and round, and there were no complications such as damage of nasal septum mucosa, exposure of prosthesis and infection of surgical site. Only 12 patients were found downward rotation of nasal tip, and 610 patients achieved satisfactory aesthetic results.Conclusions:Using septal cartilage combined with auricular cartilage is a safe, effective and suitable method for management of nasal tip shape.
ABSTRACT
Objective To present our experience and techniques with the use of autologous costal cartilage grafts in Asian rhinoplasty,and to report the surgical results and complications in 86 consecutive rhinoplasty cases.Methods All operations were performed by the first author (Liu AT) with open approach,costal cartilages and perichondrium were used to reconstruct the nasal tip projection according to the tripod theory in rhinoplasty,after removing the previous injection material,L-shaped implant or hypertrophic scar tissue in the tip.Medical charts and operative records were reviewed retrospectively to summary the complications.Nasal dorsum augmentation was done by costal cartilage or I-shaped allograft,sometimes with anterior sheath of rectus abdominis.Patients' subjective satisfaction of the postoperative nasal appearance was self-evaluated with grading (1 worse,2 no change,3 improved,and 4 much improved).Results From September 2015 to March 2017,86 patients underwent rhinoplasty at our hospital.The postoperative follow-up duration was 6 to 20 months.Overall,functional and aesthetic outcome was satisfactory in most patients,and the mean score by the patients' self-evaluation was 3.3 ± 0.6.Graft exposure,mobility,or significant resorption,pneumothorax or significant donor-site pain were not observed.Conclusions Even with minimal complications and morbidities,autologous costal cartilage grafts in Asian rhinoplasty is a versatile and reliable graft material for nasal tip surgery in severe short or saddle nose,contracted nose due to previous L-shaped augmentation and revision rhinoplasty in which the septal cartilage has already been harvested.

ABSTRACT Introduction: Rhinoseptoplasty is a complex and challenging surgery. It addresses nasal aesthetics and functionality. Aim: To describe the experience in rhinoseptoplasty performed by the Nose Committee at our medical center. Material and method: Descriptive study, of the all rhinoseptoplasties performed by the Nose Committee between 2013 and 2015. Results: 265 patients underwent surgery in the 3-year period; 164 (61.8%) were women and the mean age was 29 years (range 13-73). Most were primary surgeries (secondary: 2.6%). An external approach was most commonly used (92.5%). Nasal tip surgery was performed in 253 (95.5%) patients; osteocartilaginous dorsum reduction in 252 (95,1%), and augmentation in only 5 (1,9%). Osteotomies were frequent: paramedian in 229 (86.4%), bilateral percutaneous lateral osteotomies in 217 (81.9%) and unilateral percutaneous lateral in 17 (6.4%). Regarding nasal tip grafts, columellar strut was most often used, in 241 (90,9%) patients, followed by the shield graft in 69 (26,0%). For the dorsum, autospreaders were used in 124 (46.7%), and spreader grafts in 109 (41.1%). Conclusions: Open rhinoseptoplasty was the most commonly used approach. This has shown favorable for residents due to better exposition of nasal anatomy. Only 2.6% were secondary rhinoseptoplasties. We emphasize the use of the columellar strut for nasal tip support as we frequently encounter hispanic noses at our center.

Introduction: The management of the nasal contours is vital to achieve a satisfactory result in rhinoplasty. Sometimes the reorientation of structuresis not enough to achieve this, therefore grafts should be used to obtain adequate aesthetic and functional results. Aim: To describe the nasal tip grafts used in primary rhinoplasty, its benefits as well as the author's experience using the open and closed approaches. Material and method: A retrospective study was performed by reviewing medical records, surgical protocols and pre, intra and postoperative photographic archives of all patients in whom primary rhinoplasty was performed between April 2012 and March 2015. Epidemiological data, surgical technique and nasal tip grafts used were evaluated. Results: Casuistry of 143 patients who underwent rhinoplastyand during period is described, with an average age of 29 years, 69% female and 31% male. The closed approach was performed in 55%. Nasal tip grafts was used in 136 patients where autologous septal graft was used in 100% of cases. The grafts most used were the strut graft (93%) and the morselized cartilage on the domes (85%). Also used were the following grafts: alar batten, alar rim, shield, strut alar, caudal septal extension, and seagullwing, but to a lesser extent. Conclusion: The nasal tip grafts should be an obligatory arsenal of the otorhinolaryngologist, its correct use will allow us to achieve an adequate management of nasal contours and satisfactory aesthetic and functional results.

Objective To analyze the plasty of the tip framework and the nasal tip in insufficient-lining cases with auricular and septal cartilage.Methods The tip framework was formed by using septal extension graft (SEG) and columellar strut (CS) to construct the main framework of nasal tip,and then according to the size of the graft the next processes were chosen for supporting structure.When the graft size met the tip position,the caudal margin of the framework could be beyond the maximum stretch position of the lower lateral cartilage and reached or was close to the expected tip position.When the graft size was insufficient,auricular cartilage was used to hold the caudal margin of the framework to extend or to heighten the framework further.Refined plasty of nasal tip was as follows:when the end of framework was higher than or equal to the dome above 3 mm,auricular cartilage strip was used to reconstruct the dome;when less than 3 mm,multilayer onlay grafts were used to heighten the dome.Results From May 2013 to May 2015,42 cases were followed up from 6 months to 18 months.18 cases belonged to the type 1,including 13 cases using ear cartilage to reconstruct dome,5 cases using onlay graft;24 cases belonged to the type 2,including 14 cases using onlay graft and 10 cases using ear cartilage to reconstruct the dome.They all got good results.Conclusions To the insufficient lining cases,the appropriate method can be chosen to form stable tip framework according to the preoperative design and the graft size.Then onlay grafts or dome reconstruction technique is used to form the tip.Most of the insufficient-lining cases can get satisfactory results.
ABSTRACT
Objective To explore a new method of nasal tip plasty and its clinical effect,which is much accorded with biomechanical properties of the human body.Methods From June 2010 to March 2016,a total of 33 cases of nasal tip surgery,6 males and 27 females,were performed.Ages ranged from 22 to 46 years in this group.Ear cartilage was trimmed into two strips and sutured them together in a M shape.When located to the original position of the nasal alar cartilage,theM shaped cartilage could be used in nasal tip;when fixing part of it on the nasal septum or lengthened nasal septal cartilage,the M shaped cartilage could be used in cosmetic surgery of nasal tip lengthening.Results The follow-up period was from one month to 60 months,with average 14 months.29 patients (87.9 ％) were satisfied with the efficacy and 2 patients were suffered from infection (6.1 ％).Conclusions When the M-shaped cartilage is fixed with lengthened nasal septum,it can lengthen the nasal tip much more and the contouring and texture of nasal tip are better than that of using a shield or a cap cartilage graft.
ABSTRACT
BACKGROUND: Plastic surgeons have constantly investigated methods of nasal tip plasty and nasal lengthening in rhinoplasty. The septal extension graft has been widely applied as a very useful method for East Asians who have different internal nasal structures and nasal skin from those of Caucasians. In this study, we performed nasal tip plasty with a batten-type septal extension graft using ear cartilage. METHODS: Nasal tip plasty was performed for 48 patients by batten graft with ear cartilages at the Cocoa Plastic Surgery Clinic and in the plastic surgery unit of Hanil General Hospital from January 2009 to January 2015. A batten-type septal extension graft was constructed with cymba of the concha cartilage. An average area of 2.0 cm × 1.4 cm of the cymba and 1.0 cm × 1.0 cm of the cavum from the concha cartilage was harvested. RESULTS: Of the 48 patients who underwent batten-type septal extension graft using ear cartilages, nasal tip plasty and columellar lengthening were successfully achieved in almost all of the patients. The nasal tip's height was well-maintained for the follow-up period ranging from 6 months to 5 years after surgery. CONCLUSIONS: Nasal tip plasty using a septal extension graft is a very useful method for East Asians with a low nasal tip. The septal extension graft with ear cartilage enables the creation of a desirable nasal shape because there is a sufficient amount of ear cartilage to stably support the nasal tip, thus creating a natural and smooth nose shape.

BACKGROUND: Correction of a bulbous tip is a difficult procedure in Asians, because their lower lateral cartilage is relatively small and structurally weak to support the thick skin soft tissue envelope (SSTE). Therefore, lower lateral cartilage manipulation alone yields inadequate bulbous tip correction. In this study, authors aim to provide a new bulbous tip definition reflecting nasal tip SSTE and categorization with a suitable surgical procedure. METHODS: One hundred sixty-three patients with tip rhinoplasty between January 2009 and December 2012 were studied who had a tip lobular width greater than 60% of the alar base width. Depending on cartilage size and characteristics of the nasal tip superficial musculoaponeurotic system (SMAS) with SSTE thickness, the following classifications were made: Group I: thin SSTE with a large lower lateral cartilage, Group II: thick SSTE with a small lower lateral cartilage, Group IIa: thick SSTE with loose SMAS, and Group IIb: thick SSTE with dense SMAS. We evaluated the degree of surgical improvement by comparing pre- and postoperative photographs. RESULTS: After comparing pre- and postoperative photos, we observed improvements in tip bulbosity by 11.7% in Group I (n=41), 11.9% in Group IIa (n=64), and 7.1% in Group IIb (n=58). CONCLUSIONS: In Asians, nasal tip bulbosity is often due to excess SSTE. Therefore, a bulbous tip should be defined and evaluated based on its underlying SSTE. Adequate soft tissue resection in addition to lower lateral cartilage support and manipulation are warranted to achieve a refined tip.

El manejo de la punta nasal es un elemento clave en toda rinoplastía. Las primeras técnicas empleadas sacrificaban la estructura del arco alar con resultados posoperatorios indeseables. En la era moderna de la rinoplastía, el manejo de la punta nasal se enfocó en remodelar, preservar y reposicionar los cartílagos alares mediante el uso de suturas. El punto interdomal es una sutura en forma de ocho o loop simple desde la porción más anterior de un domo hacia el contralateral uniendo la región más alta de las cruras mediales. En el presente artículo se realiza una revisión del uso de puntos de suturas en el manejo de la punta nasal, se describen las características del punto interdomal en técnica cerrada y se muestran sus resultados en una serie de casos.
The nasal tip surgery is a key element in rhinoplasty. The first techniques employed sacrificed the alar arch structure with undesirable postoperative results. In the modern era of rhinoplasty, nasal tip surgery focused on reshaping, preserving and repositioning the alar cartilages using reversible sutures. The interdomal suture is a figure-eight or simple loop suture placed from the most anterior portion of one dome to the contralateral joining the highest region of the medial crura. This article reviews the use of suture techniques in nasal tip reshaping and describes the interdomal suture in closed approach and its results in a clinical series.

Objective To explore the clinical methodology and comparative analysis of both autogenous septum cartilagineum nasi or Medpor surgical implant in secondary unilateral cleft lip rhinoplasty.Methods Thirty-six patients with varied secondary nasal deformities of unilateral cleft lip were treated,autogenous septum cartilagineum nasi or Medpor surgical implant were implanted to supply the powerful supporting strength for nasal constructions.An anthropometry method based on the quantitative analysis of the characteristics of nasal deformity was used to evaluate and compare the preoperative and postoperative measure of the patients.Results After 6 to 24 months follow-up,all 36 cases received satisfactory results.20 of them used autologous septum cartilagineum nasi to supply the powerful supporting strength for nasal construcions,and other used Medpor surgical implant.No rejection and exposure of implants were found.The postoperative quantitative measurement results supported that both of the implants could effectively correct nasal deformities.Conclusions Both of the implants could effectively correct nasal deformities of unilateral cleft lip in secondary rhinoplasties.The quantitative measurement is a scientific approach to evaluate the outcome.
ABSTRACT
Objective To explore more satisfactory results in correcting the aesthetically short nose combined with low and blunt nasal tip by using autologous cartilage grafts.Methods External rhinoplasty approach was preferred.Nasal septal cartilage and auricular cartilage or rib cartilage of patients were adopted,as necessary,various shapes of grafts were carved,such as septal extention graft,columella strut and shift graft.Then we used these autologous cartilage grafts with suture and removal techniques to correct the aesthetically short nose combined with low and blunt nasal tip.The length of the nose (n-prn) and the projection of nasal tip (sn-prn) were measured before and after the operation.Paired t-test was adopted to evaluate the results.Results Thirty-one patients accepted the nasal tip rhinoplasty with autologous cartilage whose nasal tip was over rotation,blunt and low.All the patients were followed up for 3 months.Thirty patients satisfied with the results,accounting for 96.7 ％ of the total.()ne (3.3 ％) patient dissatisfied with the result because of postoperative asymmetry nostrils.Nose length before and after surgery was significantly different (P＜0.05).Nasal tip projection before and after surgery was also significantly improved (P＜0.05).Conclusions It is an effective method to use autologous cartilage graft for correcting the aesthetically short nose combined with low and blunt na sal tip,with low complications.
ABSTRACT
Objective To evaluate the role of autologous septal cartilage in the rhinoplasty of the wide and bulbous nasal tip. Methods A big piece of autologous nasal septal cartilage was removed and transplanted to the front of nasal septum, acting as a septal extender to fix the nasal alar cartilage,and then the shape of nasal tip was reconstructed by middle crus suture technique, excessive soft tissue under skin of tip and a part of lateral crura cartilage were removed to stand out the shape of the nasal tip. Results After one year follow-up, 118 of 126 cases achieved satisfied effects, but 8 cases dissatisfied because of their undue thick skin.
