ABSTRACT

Se describen distintos aspectos del rinofima: historia, etiopatogenia, histopatología, epidemiologia, clínica, diagnósticos diferenciales, tratamientos y pronóstico. Se hace hincapié en que es una enfermedad localizada en la nariz asociada a desórdenes generales, y que repercute en las áreas psicológica y social. Se presenta un caso clínico operado con cirugía plástica. Los autores plantean una hipótesis sobre la etiopatogenia y la fisiopatología de la enfermedad; y consideran a los tratamientos de rinofima como paliativos y no curativos


Different aspects of rhinophyma were described: history, etiopathogeny, histopathology, epidemiology, clinical, differential diagnoses, treatments and prognosis. It is emphasized that it is a localized disease in the nose associated to general disorders, and that it brings psychological and social problems. We present a case operated with plastic surgery. The authors present a hypothesis about the etiopathogeny and pathophysiology of the disease and consider rhinophyma treatments as palliative and non-curative.

ABSTRACT

Introducción. Los defectos de cobertura en la región nasal secundarios a resecciones oncológicas deben ser cubiertos con tejido de las mismas características que el resecado, idealmente con tejido vascularizado adyacente. El colgajo bilobulado reúne las condiciones doble transposición, con una estructura y diseño que permite una adecuada distribución de las fuerzas de tensión a lo largo de su eje de rotación, evitando deformidades y excedente cutáneo generados por otros colgajos o cierre primario, respetando las unidades estéticas de la nariz. Método. Se presentan 48 casos clínicos en el periodo abril 2018 - abril 2020 describiendo la técnica de realización del colgajo bilobulado para la reconstrucción de secuelas de resección oncológica nasal por los diferentes tipos de tumores de piel. Para defectos de dorso nasal 26, punta nasal 14 y alares 8 casos. Resultados. La vitalidad de los colgajos fue de un 100%, 6 casos presentaron dehiscencia en extremo distal que requirió revisión. Adecuado resultados estéticos con similitud de textura y color de piel del colgajo. Cicatrices resultantes en área dadora y receptora ocultas en líneas de sombra. Disminución de complicaciones agregando resección triangular adicional. Conclusiones. Los defectos de tegumento en región nasal deben ser cubiertos por tejido vascularizado. Las resecciones de hasta 3 cm de diámetro pueden ser cubiertas con colgajos bilobulados adyacentes. El adecuado planeamiento de las cicatrices tanto en área dadora como receptora permite mejores resultados estéticos. Siempre deben tenerse en cuenta las regiones estéticas para obtener mejores resultados.


Background. Coverage defects in the nasal region secondary to oncological resections should be covered with tissue of the same characteristics as the resected, ideally with adjacent raised vascular tissue. The bilobed flap meets the conditions, is a double transposition flap, with a structure and design that allows an adequate distribution of the tension forces along its axis of rotation, avoiding deformities and excess skin generated by other flaps or primary closure. Respecting the aesthetic units of the nose. Methods. 48 clinical cases are presented in the period April 2010- April 2020 describing the technique of making the bilobed flap for the reconstruction of the sequelae of nasal oncological resection by the different types of skin tumors. For dorsal defects 26, nasal tip 14 and alares 8 cases. Results. The vitality of the flaps was 100%, 6 cases presented dehiscence in the distal end that required revision. Adequate aesthetic results with similarity of texture and skin color of the flap. Resulting scars in donor and recipient area hidden in shadow lines. Decrease complications by adding additional triangular resection. Conclusions. Integument defects in the nasal region should be covered by vascularized tissue. Resections up to 3 cm in diameter can be covered with adjacent bilobed flaps. The adequate planning of the scars in both the donor and recipient areas allows for better aesthetic results. Aesthetic regions should always be taken into account to obtain better results

ABSTRACT

Objetivo: analizar las características del perfil facial como herramienta fundamental en la rinoseptoplastia funcional de los pacientes que consultan en la Unidad de Rinología del Servicio de Otorrinolaringología del Hospital Militar Dr. Carlos Arvelo, entre enero y abril de 2016. El rostro está formado por estructuras anatómicas que le proporcionan características determinadas. La nariz ocupa un lugar central, el diagnóstico preciso de las alteraciones nasales es el paso más importante y complejo de una rinoseptoplastia funcional. El propósito de la restauración quirúrgica de la nariz es asegurar el buen funcionamiento y la armonía en la forma, por lo que los ángulos del perfil facial son relevantes en la valoración prequirúrgica. Materiales y métodos: estudio descriptivo ­ observacional de corte transversal. La muestra estuvo conformada por 25 pacientes que accedieron voluntariamente a realizar estudio fotográfico y rinomanometría. Resultados: predominio del sexo femenino con 72% de la muestra total. El grupo etario preponderante estuvo conformado en un 92% por adultos jóvenes. En cuanto a los ángulos nasolabial y nasofacial, presentaron alteraciones el 56% y el 24% respectivamente. Se practicó rinomanometría a la población evidenciando 100% alteración (factor valvular), de los cuales un 80% presentaron modificación de los ángulos nasofacial y nasolabial. Conclusiones: la correlación entre la variación de los ángulos nasofacial y nasolabial con la permeabilidad nasal, establece que el análisis facial puede considerarse como herramienta fundamental para la determinación de correcciones estéticas y funcionales en la rinoseptoplastia funcional..Au


Objective: to analyze the characteristics of the facial profile as a fundamental tool in functional rhinoseptoplasty of patients who consult in the Rhinology Unit of the Otolaryngology Service of the Hospital Militar Dr. Carlos Arvelo, between January and April 2016. The face is made up of structures anatomical that provide certain characteristics. The nose occupies a central place, the precise diagnosis of nasal alterations is the most important and complex step of a functional rhinoseptoplasty. The purpose of the surgical restoration of the nose is to ensure proper function and harmony in shape, so the angles of the facial profile are relevant in the presurgical assessment. Materials and methods: descriptive-observational cross-sectional study. The sample consisted of 25 patients who voluntarily agreed to carry out a photographic study and rhinomanometry.Results: prevalence of the female sex with 72% of the total sample. The preponderant age group was made up of 92% young adults. Regarding the nasolabial and nasofacial angles, 56% and 24% presented alterations respectively. Rhinomanometry was performed on the population showing 100% alteration (valvular factor), of which 80% presented modification of the nasofacial and nasolabial angles. Conclusions: the correlation between the variation of the nasofacial and nasolabial angles with nasal patency establishes that facial analysis can be considered as a fundamental tool for determining aesthetic and functional corrections in functional rhinoseptoplasty..Au

ABSTRACT

Las lesiones de la región nasofrontal en los niños son un reto diagnóstico debido a su rareza, y su potencial comunicación con el sistema nervioso central también aumenta su complicaciones. Dentro de las principales entidades de esta región se encuentran los quistes dermoides, los gliomas nasales y los encefaloceles. Un abordaje diagnóstico y terapéutico inapropiado podría generar desde simples recurrencias hasta fistulas e infecciones en el sistema nervioso central, que podrían contribuir a mayores complicaciones o incluso, poner en riesgo la vida de los pacientes.


Injuries to the naso-frontal region in children are a diagnostic challenge, associated with their rarity, their complexity also implies their potential communication with the central nervous system. Dermoid cysts, nasal gliomas, and encephaloceles are among the main entities in this region. An inappropriate diagnostic and therapeutic approach could generate from simple recurrences (as in our case), to fistulas and infections of the central nervous system that could contribute to greater complications or even put the lives of patients at risk.

ABSTRACT

Abstract: Evaluating factors that may influence the nose dimensions and, therefore, contribute to the singularity of a person, is important for obtaining a precise facial reconstruction (FR) in forensic anthropology. Thus, the aim in this study was to evaluate the influence of sex, skeletal class, and facial type on nose dimensions of Brazilian individuals using cone-beam computed tomography (CBCT) scans. CBCT images of 54 males and 67 females were classified according to skeletal class (class I, II, or III) and facial type (brachycephalic, dolichocephalic and mesocephalic). Linear and angular measurements of the nose were performed using the CS 3D Imaging software. The measurements obtained for males and females were compared by one-way ANOVA. Two-way ANOVA was used to compare the measurements in the different skeletal classes and facial types. Significance level was set at 5%. All linear measurements were greater in males (p < 0.05); the angular measurements, however, did not differ between sexes (p > 0.05). Linear and angular measurements of class III males were significantly different from the other classes; the same was observed for the angular measurements in females (p < 0.05). Regarding facial types, some linear measurements were significantly greater in dolichocephalics males (p < 0.05). For females, there was no influence of facial type (p > 0.05), except for the nasal convexity angle. Nose dimensions differed in specific points among different skeletal classes and facial types, and there was sexual dimorphism in all linear nose dimensions. This information may be applicable for nose reconstructions, allowing more reliable FR.

ABSTRACT

Abstract Introduction: Total rhinectomy is an uncommon procedure for the treatment of nasal malignancies, usually reserved for locally advanced tumors. There are few case series studying total rhinectomy in the literature, reporting conflicting results about recurrence and metastasis. Objective: Evaluate prognosis of total rhinectomy cases for malignant neoplasia in our institution. Methods: Retrospective review from January 2013 to September 2018, including all patients undergoing total rhinectomy in our Institution, under the care of the Head and Neck surgical team. Results: Ten patients were included, two men and eight women. The mean patient age was 71.6 years old. The majority had nasal skin (8 cases) carcinomas. Squamous cell carcinoma was present in seven cases. In total, six cases had regional metastasis, in a median period of 14.3 months. The overall mortality and disease specific mortality was 50% and 30%, respectively, in a median follow-up of 45.7 months. Conclusion: We observed high overall and disease-specific mortality among cases with advanced nasal malignancies undergoing total rhinectomy.


Resumo Introdução: A rinectomia total é um procedimento incomum para o tratamento de neoplasias nasais, geralmente reservado para tumores localmente avançados.

ABSTRACT

Abstract Background: Mohs micrographic surgery is worldwide used for treating skin cancers. After obtaining tumor-free margins, choosing the most appropriate type of closure can be challenging. Objectives: Our aim was to associate type of surgical reconstructions after Mohs micrographic surgery with the characteristics of the tumors as histological subtype, anatomical localization and especially number of surgical stages to achieve complete excision of the tumour. Methods: Transversal, retrospective analyses of medical records. Compilation of data such as gender, age, tumor location, histological subtype, number of stages to achieve clear margins and type of repair used. Results: A total of 975 of facial and extra-facial cases were analyzed. Linear closure was the most common repair by far (39%) and was associated with the smallest number of Mohs micrographic surgery stages. This type of closure was also more common in most histological subtypes and anatomical locations studied. Using Poisson regression model, nose defects presented 39% higher frequency of other closure types than the frequency of primary repairs, when compared to defects in other anatomic sites (p< 0.05). Tumors with two or more stages had a 28.6% higher frequency of other closure types than those operated in a single stage (p< 0.05). Study limitations: Retrospective study with limitations in obtaining information from medical records. The choice of closure type can be a personal choice. Conclusions: Primary closure should not be forgotten especially in surgical defects with fewer stages and in non-aggressive histological subtypes in main anatomic sites where Mohs micrographic surgery is performed.

ABSTRACT

La armonía facial en ortodoncia está determinada por las relaciones morfológicas y proporcionales de la nariz, los labios y el mentón. Debido a que la nariz se encuentra en el centro de la cara, sirve junto con los labios y el mentón para caracterizar la apariencia facial, única para cada individuo. Junto con su función respiratoria, la configuración de la nariz, también, tiene un fuerte impacto en la estética facial general y, en gran medida, influye en el grado de convexidad del perfil. El objetivo de este trabajo fue determinar la relación entre el ángulo ANB y el ángulo nasolabial en pacientes con Clase I, II y III esqueletal, a través de trazados cefalométricos, en radiografías laterales de cráneo, con perfil facial, iniciales de un tratamiento de ortodoncia. Para esto, se midieron 200 radiografías laterales de cráneo de pacientes con dentición permanente de ambos sexos. Se hizo un análisis cuantitativo de los datos registrándolos con estadística descriptiva, y gráficos de barra y torta. Se utilizó el coeficiente de correlación de Pearson para determinar si las medidas de los ángulos mencionados, tenían una correlación estadísticamente significativa. Se determinó que los pacientes con normoclusión presentaron una correlación positiva con un ángulo nasolabial normal, los pacientes con mesioclusión presentaron una correlación negativa con un ángulo nasolabial obtuso, y los pacientes con una distoclusión presentaron correlación con un ángulo nasolabial normal(AU)


The facial harmony in orthodontics is determined by the morphological and proportional relations of nose, lips and chin. As the nose is in the center of the face, it serves together with lips and chin to characterize the facial appearance, unique to each individual. Along with its respiratory function, the nose configuration also has a strong impact on overall facial aesthetics and greatly influences the degree of convexity of the profile. The purpose of this paper was to determine the relation between the ANB angle and the nasolabial angle in patients with skeletal Class I, II and III, through cephalometric tracings, on lateral skull radiographs, with facial profile, that were initial of an orthodontic treatment. For this purpose, 200 lateral skull radiographs of patients with permanent dentition, of either sex, were measured. A quantitative analysis of the data was made, recording them through descriptive statistics, and bar graphs and pie charts. Pearson's correlation coefficient was used to determine whether the measurements of the mentioned angles had a statistically significant correlation. It was established that patients with normocclusion showed a positive correlation with a normal nasolabial angle, patients with mesiocclusion presented a negative correlation with an obtuse nasolabial angle and patients with distocclusion had correlation with a normal nasolabial angle(AU)

ABSTRACT

Introdução: O aumento da projeção da ponta nasal às vezes se torna necessário para a obtenção de uma boa proporção entre ela e o dorso. Inúmeras técnicas e táticas são descritas com essa finalidade utilizando enxertos cartilaginosos obtidos do septo nasal, concha auricular e cartilagem costal. Quando esse aumento deve ser discreto é proposto o uso dos excedentes de cartilagens alares laterais em forma de "pseudo-retalhos". Métodos: Em rinoplastias abertas primárias os excedentes das cartilagens alares, geralmente removidas, são utilizados como "pseudo-retalhos", dobrados sobre si mesmos, em forma de "suspensório de soldado francês", sobre o domus das cartilagens alares, tendo como acolchoamento de apoio os tecidos moles delas próprias, e o tecido mole interdomal, geralmente desprezado, que é liberado, e elevado para sobre os domus. Ele é mantido, descolado e deslocado para a ponta nasal, e fica contido pelos "pseudo-retalhos" das cartilagens alares ali suturados ou cobrindo o extremo do enxerto estrutural da columela. Foram operados com essa tática 36 pacientes. Resultados: 35 com bons resultados e um apresentou um abcesso de ponta nasal, provocado pela exposição endonasal de um fio de sutura não absorvível, que foi removido. Houve necessidade de uma segunda intervenção, utilizando novo enxerto auricular, ainda com resultado insatisfatório. O método é relativamente simples para quem opera narizes. Conclusão: A ponta nasal pode ser discretamente mais projetada utilizando os excessos de cartilagens alares, "pediculadas" no domus.


Introduction: An increased nasal tip projection is sometimes necessary to achieve an appropriate proportion between nasal tip and dorsum. Numerous techniques and tactics have been described for this purpose using cartilaginous grafts obtained from the nasal septum, auricular concha, and costal cartilage. When this increased projection must be discrete, the use of excess lateral alar cartilage in the form of "pseudo-flaps" is proposed. Methods: In primary open rhinoplasty, excess alar cartilage, which is generally removed, was used to produce "pseudo-flaps". The cartilages were folded over themselves in the form of a "French soldier's suspender" over the domes of the alar cartilage and supported by interdomal soft tissue padding raised over the domus. It was kept detached, and relocated to the nasal tip and was contained by "pseudoflaps" of the alar cartilages sutured there or covering the columella's structural graft. Thirty-six patients underwent surgery using this technique. Results: Thirty-five had good results and one had a nasal tip abscess, caused by endonasal exposure to a non-absorbable suture, which was removed. A second intervention was then performed using a new auricular graft, but the result was still unsatisfactory. The "pseudoflaps" method is relatively simple for those performing nasal surgery. Conclusion: The nasal tip can be projected discretely using the excess of alar cartilage "pedicled" in the domus.

ABSTRACT

Hemangioma infantil (HI) é o tumor vascular mais comum e a neoplasia benigna mais frequente da infância, com maior incidência no sexo feminino e na população branca. Quase 60% dos casos ocorrem em cabeça e pescoço, sendo o tratamento ativo durante a fase proliferativa mais frequentemente indicado, em decorrência dos possíveis problemas funcionais e do potencial desfigurante. Relatamos um caso de paciente com hemangioma infantil involuído de ponta nasal e lábio superior, tratado de forma expectante durante a infância, submetida à correção da deformidade residual com técnicas de rinoplastia, associado à zetaplastia e lipoenxertia do lábio superior com bom resultado e satisfação do paciente.


Infantile hemangioma (IH) is the most common vascular tumor and the most frequent benign neoplasm in childhood, with the highest incidence in females and the white population. Almost 60% of cases occur in the head and neck, and active treatment during the proliferative phase is the most frequently indicated, due to possible functional problems and disfiguring potential. We report a case of a patient with involute infantile hemangioma of the nasal tip and upper lip, treated expectantly during childhood, submitted to residual deformity correction with rhinoplasty techniques, associated with zetaplasty and upper lip grafting with good results and patient satisfaction.

ABSTRACT

The aim of this investigation was to define the volume and area of the airway in subjects with Class II and Class III skeletal deformity. A cross-sectional study was designed including subjects with facial deformity defined by Steiner's analysis in subjects with indication of orthognathic surgery who presented diagnosis by cone beam computerised tomography. We determined the measurements of maximum area, minimum area and volume of the airway. The data were compared using Spearman's test, with statistical significance defined as p<0.05. 115 subjects were included: 61.7 % Class II and 38.3 % Class III, mean age 27.8 years (± 11.6). A significant difference was observed in the area and volume measurements in the groups studied, with significantly smaller measurements found in Class II (p=0.034). The minimum area was 10.4 mm2 smaller in Class II patients than in Class III, while the general volume of the airway was 4.1 mm3 smaller in Class II than in Class III. We may conclude that Class II subjects present a smaller airway volume than Class III subjects.

ABSTRACT

Objective: To determine regression models to predict the mesiodistal widths of the maxillary anterior teeth from interalar width of the nose in subjects with facial harmony. Materials and Methods: A cross-sectional study was carried out in a sample of 75 subjects with facial harmony and ages ranging from 18 to 30 years (21.28±3.75 years). The mesiodistal width of the central (CI), lateral (LI) incisors, and canines (C), as well as the interalar width (IW) of each subject were measured using a digital vernier caliper. Simple linear regression analyses were used to predict the width of the maxillary anterior teeth from the nasal interalar width, from which formulas for predicting the dimensions of each anterior tooth were obtained. Results: A statistically significant relationship was found between the nasal interalar width and the mesiodistal widths of the upper central incisor (p=0.019, R2=5.23%), upper lateral incisor (p=0.019, R2=2.31%), and upper canine (p=0.016, R2=12.04%) that allowed to develop simple linear prediction models for each tooth represented by the following formulas: CI=7.04+0.04(IW); LI=6.01+0.03 (IW); C=6.19+0.05 (IW). Conclusion: The nasal interalar width is a good predictor of the mesiodistal widths of the maxillary anterior teeth.


Objectivo: Determinar modelos de regresión para predecir los anchos mesiodistales de los dientes anterosuperiores a partir del ancho interalar de la nariz en individuos con armonía facial. Materiales and Métodos: Se realizó un estudio transversal con una muestra de 75 sujetos con armonía facial entre 18 a 30 años (21.28 ± 3.75 años), se midió el ancho mesiodistal de incisivos centrales (IC), laterales (IL) y caninos (C) así como el ancho interalar (AI) de cada sujeto empleando un calibrador vernier digital. Para la predicción del ancho de los dientes anterosuperiores a partir del ancho interalar nasal se emplearon análisis de regresión lineal simple, a partir de los cuales se obtuvieron fórmulas de predicción de las dimensiones de cada pieza dentaria anterior. Resultados: Se encontró relación estadísticamente significativa entre el ancho interalar nasal y los anchos mesiodistales del incisivo central superior (p=0.019, R2 5.23%), incisivo lateral superior (=0.019, R2=2.31%) y canino superior (p=0.016, R2=12.04%) que permitieron generar modelos de predicción lineal simple para cada pieza dentaria representados mediante las siguientes fórmulas: IC=7.04+0.04(AI); IL=6.01+0.03(AI); C=6.19+0.05(AI). Conclusión:El ancho interalar nasal es un buen predictor de los anchos mesiodistales de los dientes anterosuperiores.

ABSTRACT

Abstract The objectives of pre-surgical orthopedics are to allow surgical repair with minimal tension of the involved tissues and less restriction to the craniofacial growth. The aim of this study was to evaluate the benefits of nasoalveolar model (NAM) as a pre-operative therapy in a patient with bilateral cleft lip and palate followed by labioplasty and palatoplasty. A 15-day-old patient underwent orthopedic treatment with NAM. After pre-operative treatment, retraction of the pre-maxilla was observed with reduction of the fissure. Due to the successful effects of NAM treatment the patient had a one-step surgery for lip correction. Six months later, due to lip pressure the fissure was further decreased. After six months, the patient underwent palatoplasty. Both surgeries contributed to the remaining closure of the fissure, which were reduced by half compared to the end of pre-operative treatment. The uses of NAM as a pre-operative treatment approached the alveolar segments, centralized the pre-maxilla, decreased the cleft palate resulting in a marked improvement of the arch and provide superior surgical results. In addition, it allows the primary repair of the patient's lip with asymmetric bilateral fissure in only one-step surgery; in consequence, it will reduce treatment morbidity and decrease cost of treatment.


Resumo Os objetivos da ortopedia pré-cirúrgica são permitir a correção cirúrgica com mínima tensão dos tecidos envolvidos e menor restrição ao crescimento craniofacial. O objetivo deste estudo foi avaliar os benefícios do modelo nasoalveolar (NAM) como terapia pré-operatória em um paciente com fissura labiopalatina bilateral seguida de labioplastia e palatoplastia. Um paciente de 15 dias de idade foi submetido a tratamento ortopédico com NAM. Após o tratamento pré-operatório, observou-se retração da pré-maxila com redução da fissura. Devido aos efeitos bem-sucedidos do tratamento com NAM, o paciente realizou a cirurgia em um único tempo cirúrgico para correção dos lábios. Seis meses após verificou-se a continuidade da redução da fissura devido à pressão labial. Após dozes meses, o paciente foi submetido à palatoplastia. Ambas as cirurgias contribuíram para o fechamento remanescente da fissura, que foram reduzidas pela metade em comparação com o final do tratamento pré-operatório. O uso do NAM como tratamento pré-operatório proporcionou a aproximação dos segmentos alveolares, centralização da pré-maxila, diminuição da fissura palatina, resultando em melhora acentuada do arco, resultando em procedimentos cirúrgicos mais eficazes. Além disso, permitiu o reparo primário do lábio do paciente com fissura bilateral assimétrica em apenas uma cirurgia; em conseqüência, reduzindo a morbidade do tratamento e diminuição dos custos do tratamento.

ABSTRACT

La rinoplastia es una de las cirugías estéticas más realizadas en el mundo y entre las complicaciones más frecuentes está el colapso valvular por la excesiva resección del cartílago alar. La parálisis facial, así como el envejecimiento pueden colapsar la pared lateral en inspiración por disfunción del músculo nasal, al provocar debilitamiento del tejido fibroalveolar de la pared lateral nasal, existiendo también causas genéticas que producen colapso valvular. Actualmente se practican diversas técnicas para mejorar el colapso valvular y ninguna es cien por ciento efectiva, la mayor parte se centran en corregir la propia válvula nasal o el cartílago triangular, lo que indica que se fijan en un solo factor y no en la etiología multifactorial que la produce. Este estudio revisa la evidencia clínica que guía a un diagnóstico correcto y al manejo efectivo de la disfunción de la válvula nasal externa, mediante el uso de diversas técnicas que se emplean actualmente para perfeccionar el colapso valvular nasal.


Rhinoplasty is one of the most frequent cosmetic surgeries in the world and among the most common complications is valve collapse due to excessive resection of the alar cartilage. Facial paralysis, as well as aging, can collapse the lateral wall in inspiration due to dysfunction of the nasal muscle, causing weakening of the fibroalveolar tissue of the nasal lateral wall, and there are also genetic causes that produce valve collapse. Currently, various techniques are practiced to improve valve collapse and none are one hundred percent effective, most of them focus on correcting the nasal valve itself or the triangular cartilage, which indicates that they are fixed on a single factor and not on multifactorial etiology that produces it. This study reviews the clinical evidence that guides a correct diagnosis and effective management of external nasal valve dysfunction, using various techniques that are currently used to improve nasal valve collapse.

ABSTRACT

Abstract Forensic facial reconstruction aids in the process of human identification by facial recognition. The nose plays an important role in this process; however, its soft tissues wither away during cadaveric decomposition. There are few studies in the area of facial recognition of the Brazilian population, especially concerning Brazilian nasal prediction guides. This study aimed to test the hypothesis that the angle formed by the tangents drawn from the rhinion and prosthion points (nose tip) is equal to 90º, as proposed by the pioneer study by Tedeschi-Oliveira et al. (2016). It is important to highlight that this is the only method to date developed to predict the nasal tip in Brazilians, and has not yet been tested in other populations. Images of computed tomography scans of 228 individuals (171 females and 57 males) were screened according to the same criteria used by the authors of the primary study. The images were analyzed using the Horos® program, version 1.1.7 - 64 bit. The mean angle studied was about 90º, and any difference between this mean and the real angle measured did not significantly compromise the accuracy of the nose tip location. The findings tested in the present study corroborate the hypothesis investigated by Tedeschi-Oliveira et. al. Therefore, we suggest that the method be used in forensic practice to estimate nose tips in Brazilians.

ABSTRACT

El objetivo de nuestro estudio de tipo longitudinal prospectivo simple de medidas repetidas fue determinar la variación del flujo aéreo nasal medido con un flujómetro nasal portátil, en niños entre 6 y 14 años de edad con compresión maxilar, después de la expansión rápida del maxilar (ERM). El trabajo constó de 16 niños diagnosticados con compresión maxilar y a quienes se les indicó una disyunción maxilar rápida. Los valores de la cantidad de expansión fueron registrados y la medición del flujo inspiratorio nasal máximo (FINM) se realizó antes de la ERM (T1), inmediatamente después (T2) y al cabo de 3 meses del período de retención (T3), manteniendo las mismas condiciones iniciales. El valor máximo y el promedio de las mediciones del FINM en T2 fueron significativamente mayores que en T1 (p-valor, 0,0056) y (p-valor 0,0062) respectivamente, mientras que entre T2 y T3 no existieron tales diferencias (p-valor: 0,3021) y (p-valor: 0,3315) respectivamente. Existe un aumento significativo en los valores del FINM inmediatamente después de la expansión rápida del maxilar que se mantienen en un período de tiempo de 3 meses.


The objective of our simple prospective longitudinal type study of repeated measures, was to determine the variation of nasal airflow measured with a portable nasal flow meter, in children between 6 and 14 years of age with maxillary compression, after rapid maxillary expansion (RME). The study consisted of 16 children diagnosed with maxillary compression and those who were identified with a rapid maxillary disjunction. The values of the amount of expansion were recorded and the measurement of the peak nasal inspiratory flow (PNIF) was performed before the ERM (T1), immediately after (T2) and after 3 months of retention period (T3), maintaining the same initial conditions. Results: the value maximum and average measurements of FINM in T2 were greater than in T1 (p-value, 0.0056) and (p-value 0.0062) respectively, while between T2 and T3 there were no differences (p value: 0.3021) and (p value: 0.3315) respectively. There is a significant increase in PNIF values immediately after rapid maxillary expansion that is in a period of 3 months.

ABSTRACT

OBJECTIVE: This study aimed to evaluate the efficacy of magnetic resonance (MR) imaging in differentiating between cutaneous basal cell carcinoma (cBCC) and cutaneous squamous cell carcinoma (cSCC) in the head and neck region.MATERIALS AND METHODS: Among patients with cutaneous head and neck cancers, 14 with primary cBCCs and 15 with primary cSCCs with a histologic tumor height of ≥ 4 mm underwent MR examinations; the findings were then examined for correlations.RESULTS: cBCCs (71%) occurred more frequently on the nose than cSCCs (13%) (p < 0.01). The maximum diameter (23.5 ± 7.2 mm vs. 12.7 ± 4.5 mm; p < 0.01) and diameter-to-height ratio (2.8 ± 0.9 vs. 1.7 ± 0.4; p < 0.01) were significantly greater in cSCCs than in cBCCs. Superficial ulcer formation (67% vs. 21%; p < 0.05), protrusion into the subcutaneous tissue (60% vs. 21%; p < 0.05), ill-demarcated deep tumor margins (60% vs. 7%; p < 0.01), and peritumoral fat stranding (93% vs. 7%; p < 0.01) were more frequently observed in cSCCs than in cBCCs. Intratumoral T2-hyperintense foci (57% vs. 13%; p < 0.05) were more frequently observed in cBCCs than in cSCCs.CONCLUSION: cBCCs predominantly occurred on the nose with intratumoral T2-hyperintense foci, whereas cSCCs predominantly exhibited a flattened configuration, superficial ulcer formation, protrusion into the subcutaneous tissue, ill-demarcated deep tumor margin, and peritumoral fat stranding.
