RESUMO

The authors propose a novel flap for rhinoplasty: the supratip cross flap (SCF). It is a simple and effective method for avoiding and correcting alar contour deformities and external nasal valve (ENV) issues in rhinoplasty without grafts. In addition to its benefit for supratip break, the flap also allows a smooth and natural transition between the nasal dorsum and the nasal tip complex.

RESUMO

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.


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.

RESUMO

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)

RESUMO

Introduction The predictability of nasal tip projection and rotation after aesthetic surgery is a challenge. Tongue-in-groove (TIG) is an effective technique to control tip projection and rotation, but there may be a small loss of projection and rotation of the tip lobe due to lack of support between the anterior septal angle and the domus, since this region is sustained by medial crusts suture-linked and interdomus sutures. Objective To describe a new surgery technique in an attempt to correct the lack of support for the nasal tip after lowering the nasal dorsum. Methods The horn technique consists in preserving a square of cartilage during the removal of the nasal dorsum and septum excess in patients with long and projected nose. This piece will give greater support to the TIG technique and greater predictability of the rotation and projection of the nasal tip. Results Between 2016 and 2018, 50 patients with long and projected noses were submitted to the "horn technique" surgery. They were submitted to the TIG technique associated to the horn technique. A retrospective review of the preoperative and postoperative photographs (3 months to 1 year) of these patients treated with the horn technique were analyzed and showed better support of the nasal tip. Conclusion The horn technique provides greater support to the projection and rotation of rhinoplasties in patients with long and projected nose.

RESUMO

RESUMEN Introducción: La rinoseptoplastía es una cirugía compleja y desafiante. Permite resolver problemas estéticos y funcionales de la nariz. Objetivo: Describir la experiencia en rinoseptoplastías realizadas en el Comité de Nariz en nuestro centro. Material y método: Estudio descriptivo de pacientes sometidos a rinoseptoplastía entre 2013 y 2015. Resultados: Se operaron 265 pacientes en 3 años, 164 (61,8%) fueron mujeres y la edad promedio fue de 29 años (rango 13-73). Las cirugías fueron principalmente primarias (secundarias: 2,6%). El abordaje más utilizado fue abierto (92,5%). Se realizó trabajo de punta nasal en 253 (95,5%) pacientes; resección del dorso osteocartilaginoso en 252 (95,1%), y aumento de éste en sólo 5 (1,9%). Las osteotomías fueron frecuentes: paramedianas en 229 (86,4%), percutánea lateral bilateral en 217 (81,9%) y percutánea lateral unilateral en 17 (6,4%). El vástago columelar fue el injerto de punta más frecuentemente utilizado, en 241 (90,9%) pacientes, seguido del escudo en 69 (26,0%). En el dorso, se utilizaron autoespaciadores en 124 (46,7%) pacientes, y espaciadores en 109 (41,1%). Conclusiones: El abordaje abierto fue el más frecuente, demostrando ser favorable en nuestro centro por la exposición y aprendizaje de nuestros residentes. Se constató 2,6% de cirugías secundarias. Se destaca el uso de vástago columelar para otorgar soporte a la punta nasal dada la alta prevalencia de nariz hispana en nuestro centro.


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.

RESUMO

Rhinoplasty is one of the main facial plastic procedures performed worldwide. Ethnic patients today are mainly mixed-race patients. Diagnosis is based on anatomical findings and surgery should be planned based on patients' needs and what they define as beautiful. Different surgical techniques are presented where a structural approach to rhinoplasty is explained. Very little tissue is resected and support structures of the nose are strengthened with sutures and grafts. A gradual approach to the nasal tip is also presented progressing from simple predictable techniques to more complex unpredictable ones. The final result should be noses with greater definition and refinement that are harmonious and blend in with patients' faces.

RESUMO

Manitoba-oculo-tricho-anal (MOTA) syndrome is an uncommon condition arising from biallelic mutations of FREM1 gene and clinically characterized by a variable spectrum of eyelid malformations, aberrant hairline, bifid or broad nasal tip, and gastrointestinal anomalies. In this report, we describe a patient with a phenotype compatible with MOTA syndrome (aberrant anterior hair line, hypertelorism, unilateral anophthalmia, and bifid and broad nasal tip) in whom two novel FREM1 mutations (c.305 A > G, p.Asp102Gly; and c.2626delG, p.Val876Tyrfs*16) were identified in the compound heterozygous state, thus broadening the mutational spectrum of the disease. We performed a literature review of the clinical and genetic features of individuals carrying FREM1 mutations.

RESUMO

Introducción: El manejo de los contornos nasales es vital para lograr un resultado satisfactorio en rinoplastía. La reorientación de estructuras, en ocasiones no es suficiente para lograr esto, por lo que se debe utilizar injertos para obtener un resultado estético y funcional adecuado. Objetivos: Describir los injertos utilizados en punta nasal en rinoplastía primaria, sus beneficios, así como la experiencia del autor mediante la utilización de éstos por abordaje abierto y cerrado. Material y método: Se realizó un estudio retrospectivo descriptivo mediante revisión de fichas clínicas, protocolos quirúrgicos y archivos fotográficos pre, intra y pos-operatorios del total de pacientes, en quienes se realizó rinoplastía primaria entre abril de 2012 y marzo de 2015. Se evaluaron datos epidemiológicos, técnica quirúrgica e injertos de punta nasal utilizados. Resultados: Casuística de 143 pacientes sometidos a rinoplastía durante periodo descrito. Con una edad promedio de 29 años, 69% mujeres y 31% hombres. La vía de abordaje fue cerrada en el 55%. Se utilizó injertos de punta nasal en 136 pacientes, empleándose injerto autólogo septal en el 100% de los casos. Los injertos más usados fueron el vástago (93%) y cartílago morcelizado sobre los domos (85%). Injertos como el listón alar, de reborde alar, escudo, vástago alar, extensión septal caudal y ala de gaviota; también fueron utilizados pero en menor medida. Conclusión: Los injertos de punta nasal deben ser un arsenal obligado del otorrinolaringólogo, su correcta utilización nos permitirá lograr un adecuado manejo de los contornos nasales y un resultado estético y funcional satisfactorio.


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.

RESUMO

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.
