Comparison of outcomes for general and local anesthesia in the management of nasal bone fractures: a meta-analysis.

BACKGROUND: This meta-analysis aimed to perform a head-to-head comparison of the role of general anesthesia (GA) and local anesthesia (LA) in the management of patients with nasal bone fractures (NBFs). METHODS: PubMed, Embase, and Web of Science were comprehensively searched. Studies investigating the clinical outcomes of GA and LA in the management of NBFs were included. Pooled odds ratios (OR) with the respective 95% confidence intervals (CIs) were calculated. Heterogeneity between the included studies was evaluated. The risk of bias in the included studies was assessed. RESULTS: Eight studies were included in this meta-analysis. The pooled ORs for cosmetic results, residual septal deformity, the need for further surgery, patients' satisfaction with the anesthesia procedure, and patients' satisfaction with the surgery results were 0.70 (95% CI 0.18, 2.64; z = - 0.53, p = 0.5957), 1.11 (95% CI 0.37, 3.30; z = 0.18, p = 0.8558), 1.19 (95% CI 0.65, 2.20; z = 0.56, p = 0.5760), 1.57 (95% CI 0.92, 2.69; z = 1.65, p = 0.0982), and 1.00 (95% CI 0.55, 1.80; z = - 0.00, p = 0.9974). CONCLUSIONS: Insignificant difference on clinical outcomes was observed between GA and LA in the manipulation of patients with NBFs, and the choice of anesthetic approach should be based on the tolerability of the methods and the severity of nasal fractures.

Rhinoplasty for post-traumatic deviation of the nose with non-incisional external perforated osteotomy.

Osteotomy is often necessary for the repair of post-traumatic nasal bone deformities. Typically, tools such as chisels are used for osteotomies; however, we performed osteotomies using Kirschner wires without making a skin incision. Between April 2011 and July 2022, we performed rhinoplasty with external perforated osteotomy using Kirschner wires in 13 patients with post-traumatic nasal bone deformities (9 males and 4 females; mean age, 34 years, range 12-51 years), all of whom exhibited improvement, with only one case showing mild residual cosmetic deformity. None of the patients requested further revision, and all were satisfied with their functional results. The non-incisional external perforated technique is a reasonable method that allows for bone osteotomies along the fracture line and is well-controlled, predictable, and reproducible.

Surgical treatment of nasal fractures may benefit from intraoperative 3D imaging.

This retrospective study aimed to assess the effects of the use of intraoperative three-dimensional (3D) imaging on outcomes in surgical treatment of nasal fractures. Furthermore, we investigated whether the use of intraoperative imaging improves outcomes and decreases the frequency of corrective surgeries compared to published literature. This retrospective descriptive study included patients who underwent operative treatment for nasal fractures with the use of intraoperative 3D imaging between January 2015 and January 2020 at a University Hospital. The primary outcome measure was patient satisfaction, which was assessed through patient charts about subjective esthetic problems and nasal obstruction. The secondary outcome measures were the number of intraoperative images and necessity of intra- and postoperative revisions. All the outcomes were evaluated using regression analysis. Of the 172 patients, secondary rhinoplasty and intraoperative revision were performed in 10 (6 %) and 93 (54 %) patients, respectively. Postoperatively, 19 (11 %) and 12 (7 %) patients complained of subjective esthetic problems and nasal obstruction, respectively. The intraoperative revision rate in patients undergoing surgical treatment of nasal fractures with intraoperative 3D imaging was >50 %. However, the incidence of postoperative secondary revision, nasal obstruction, and subjective esthetic problems was lower than that reported in the literature not having an intraoperative imaging. Our findings suggest that prompt quality control of the operative result enables immediate correction and prevents postoperative revision.

Surgical management of naso-orbito-ethmoidal fractures: a systematic review.

OBJECTIVE: Naso-orbito-ethmoidal fractures (NOE) fractures are uncommon but critical injuries. This review aims to investigate the patient factors, procedural factors, and postoperative outcomes associated with the surgical management of NOE fractures. STUDY DESIGN: PubMed and Scopus databases were systematically searched between 1993 and 2023 using the search strategy "(naso-orbito-ethmoidal OR nasoethmoid OR nasoorbitoethmoidal) AND fracture." Articles reporting clinical studies investigating the surgical management of NOE fractures were included. Articles that were duplicates, non-English, or non-full text; reported an unclear age range; reported insufficient data; and/or reported on a sample size less than 10 were excluded. Data on patient factors, procedural factors, and postoperative outcomes were extracted. RESULTS: Of the 412 articles identified, 6 eligible articles (retrospective case series) representing 95 adult cases and 84 pediatric cases were included. The mean ages were 29.0 and 10.2 years, respectively. Most cases were male (65.3%; 73.9%). Motor vehicle accidents were the most common mechanism of injury (79.2% and 50.0%, respectively). Coronal incision was the most common approach. Epiphora (n = 33) and scar problems (n = 21) were the most common complications in adult and pediatric cases, respectively. CONCLUSIONS: Further robust longitudinal studies with a clear description of fracture classification and surgical timing would be helpful. Gaps in knowledge include concomitant injuries, digitally-assisted applications, and risk factors for adverse outcomes.

Naso-Orbital-Ethmoid Fracture Repair Techniques: A Systematic Review.

PURPOSE: Naso-orbital-ethmoid (NOE) complex fractures present a challenge to repair. The classification system used to categorize the fracture type was established in 1991 based off the medial canthal tendon attachment. The primary objective was to systematically review the literature outlining repair techniques for NOE fracture after the adoption of the Markowitz classification system. METHODS: A systematic search was performed in PubMed, Embase, and Web of Science to identify peer-reviewed research. Eligible studies were peer-reviewed articles reporting on operative techniques used to repair NOE fractures in adult patients after 1991. Two investigators independently reviewed all articles and extracted data. Level of evidence was assessed by Oxford Center for Evidence-based Medicine guidelines. RESULTS: This review identified 16 articles that met inclusion/exclusion criteria representing 517 patients. One article outlined a closed reduction technique with transnasal wiring. The remaining articles discussed open approaches with various exposure techniques, most common being the coronal incision. Miniplates and screws were most often implemented for rigid fixation as well as transnasal wiring to repair disrupted medial canthal tendon and canthal bearing bone in Type 2 and 3 NOE fractures. Ten of the studies included in this review had a level of evidence of 4. CONCLUSIONS: NOE fractures present a complex fracture pattern and challenge to repair. New exposure techniques and multidisciplinary approaches have been described. However, fixation techniques have remained relatively consistent through the years. Surgeon preference and comfort with performing the specific techniques leads to the best patient outcomes. With the low level of evidence referenced, more robust research is needed to evaluate these techniques.

Satisfacción estética y funcional tras reducción cerrada de fracturas nasales: implementación de la escala NOSE / Aesthetic and functional satisfaction after closed reduction of nasal fractures: implementation of the NOSE scale

Introducción y objetivo: La fractura nasal es la lesión facial más común y más del 50 % de todas las fracturas faciales en adultos. Debido a que en muchas ocasiones no es diagnosticada y tratada oportunamente, puede generar diferentes grados de limitación funcional y resultados estéticos indeseables. Pocos estudios evalúan la satisfacción de los pacientes tratados con técnica cerrada de reducción de fractura nasal. Nuestro objetivo es valorar la satisfacción funcional y estética posterior a reducción cerrada de fractura de huesos nasales en un hospital de Colombia, mediante la escala de evaluación de síntomas de obstrucción nasal (NOSE, por sus siglas en inglés - nasal obstruction symptom evaluation) y la escala estética subjetiva. Material y método: Estudio observacional analítico prospectivo de pacientes con fractura nasal llevados a reducción cerrada en el Hospital Universitario de Santander, Colombia. Se registraron las puntuaciones de las escalas NOSE y estética subjetiva, antes y 2 meses después de la cirugía. Resultados: Evaluamos 55 pacientes, 90.9% hombres. La mediana de edad fue de 31 años (RIC 24-48). El contexto de lesión principal fue violencia física (40%), seguido de accidente de tránsito (32.7%). Tras el procedimiento, los pacientes presentaron mejoría de obstrucción nasal medida con la escala NOSE (p<0.001); antes de la cirugía el 89% presentaba obstrucción nasal moderada-severa, posteriormente descendió a 14.5%. La escala NOSE mostró fabilidad por consistencia interna con alfa de Cronbach de 0.8317. Tras la cirugía hubo aumento de la satisfacción respecto al aspecto nasal (p<0.001). Conclusiones: En nuestro estudio, el cuestionario NOSE permitió cuantificar la mejora de síntomas de obstrucción nasal en pacientes con reducción cerrada por fractura de huesos nasales. Observamos mejoría de síntomas obstructivos nasales y aumento de satisfacción estética.Nivel de evidencia científica 4c Terapéutico.(AU)

Background and objective: Nasal fracture is the most common facial injury, accounting for more than 50% of all facial fractures in adults. Because it is often not diagnosed and treated promptly, it can generate different degrees of functional limitation and undesirable aesthetic results. Few studies evaluate the satisfaction of patients treated with the closed nasal fracture reduction technique. Our objective is to evaluate functional and aesthetic satisfaction after closed reduction of a nasal bone fracture in a hospital in Colombia, using the nasal obstruction symptom evaluation (NOSE) and subjective aesthetic scales. Methods: Prospective analytical observational study of patients with nasal fractures undergoing closed reduction at the University Hospital of Santander, Colombia. The scores of the NOSE scales and subjective aesthetics were recorded, before and 2 months after surgery. Results: We evaluated 55 patients, 90.9% men. Median age 31 years (IQR 24-48). The main injury context was physical violence (40%), followed by traffic accident (32.7%). After the procedure, the patients presented improvement in nasal obstruction measured with the NOSE scale (p<0.001); before surgery, 89% had moderate-severe nasal obstruction, later it decreased to 14.5%. The NOSE scale showed reliability due to internal consistency with Cronbach's alpha of 0.8317. After surgery, there was an increase in satisfaction regarding the nasal appearance (p<0.001). Conclusions: The NOSE questionnaire allows us to quantify the improvement of nasal obstruction symptoms in patients with closed reduction due to nasal bone fracture. Improvement of nasal obstructive symptoms and increased aesthetic satisfaction was observed.Level of evidence 4c Terapeutic.(AU)

Factores relacionados con el riesgo de reintervención en pacientes operados de reducción cerrada de fractura de huesos propios / Factors related to the risk of reoperation in patients operated on for closed reduction of nasal bone fractures

INTRODUCCIÓN Y OBJETIVO: La fractura de huesos nasales es la fractura facial más frecuente. En relación a la cirugía, la técnica habitualmente empleada ante ella es la reducción cerrada bajo anestesia local o general. Presentamos nuestra experiencia en pacientes intervenidos de fractura de huesos nasales y valoramos el riesgo de reintervención en relación al tipo de técnica anestésica empleada. MATERIAL Y MÉTODO: Recopilamos datos de manera retrospectiva de pacientes intervenidos de reducción cerrada de fractura nasal en nuestro centro entre diciembre de 2014 y junio de 2019. Estudiamos la variable cualitativa analizada (la reintervención) con el test exacto de Fisher y las variables cuantitativas analizadas (días desde el traumatismo hasta cirugía y grados de desviación nasal) con el test U de Mann-Whitney. RESULTADOS: Incluimos 128 pacientes (91 hombres y 37 mujeres). La causa de fractura más frecuente fue la agresión, seguida por el traumatismo por caída y los deportes. Las fracturas por agresión se produjeron con mayor frecuencia los sábados y domingos entre las 3 y las 5 horas de la madrugada. Las fracturas por caída los lunes y martes a la 1 del mediodía. En 99 casos la cirugía se llevó a cabo en las primeras 24 horas, y en 29 pasado ese tiempo. Con respecto a la técnica anestésica, 9 pacientes fueron intervenidos bajo anestesia local, 24 bajo sedación y 95 bajo anestesia general. Tres de los intervenidos con anestesia local y 4 con anestesia general precisaron reintervención por mal resultado tras la primera cirugía. Ninguno de los pacientes intervenidos con sedación fue reintervenido. CONCLUSIONES: En nuestra experiencia, la reducción de la fractura nasal bajo sedación tiene buenos resultados, por lo que consideramos que es una buena alternativa en los casos de fractura nasal quirúrgica para reducir los efectos adversos de la anestesia general

BACKGROUND AND OBJECTIVE: Nasal bone fracture is the most frequent facial fracture. In relation to surgery, the most frequently employed technique is closed reduction under local or under general anesthesia. We present our experience with patients who underwent nasal bone fracture surgery and the risk of reintervention in relation to the type of anesthetic technique used. METHODS: Data were collected retrospectively of patients who underwent closed reduction of nasal fracture in our center between December 2014 and June 2019. Qualitative variable analyzed (reintervention) were studied with Fisher's exact test and the quantitative variables analyzed (days from trauma to surgery and degrees of nasal deviation) with the Mann-Whitney U test. RESULTS: One hundred and twenty-eight patients (91 men and 37 women) were included in the study. The most frequent cause of fracture was aggression, followed by falls and sports. Aggression fractures occurred most frequently on Saturdays and Sundays between 3 and 5 a.m. Fall fractures occurred most frequently on Mondays and Tuesdays at 1 p.m. In 99 cases the surgery was performed in the first 24 hours, while in 29 cases it was performed after that time. Regarding the anesthetic technique, 9 patients were operated under local anesthesia, 24 under sedation and 95 under general anesthesia. Three of the patients operated with local anesthesia and 4 with general anesthesia required reoperation because of poor results after the first surgery. None of the patients operated with sedation were reoperated. CONCLUSIONS: In our experience, nasal fracture reduction under sedation has good results making it a good alternative in cases of surgical nasal fracture reducing the deleterious effects of general anesthesia

Functional recovery time after facial fractures: characteristics and associated factors in a sample of patients from southern Brazil / Tempo de recuperação funcional após fraturas faciais: perfil e fatores associados em amostra de pacientes do sul do Brasil

ABSTRACT Understanding the cause, severity, and elapsed time for the restoration of the functions of maxillofacial injuries can contribute to the establishment of clinical priorities aiming at effective treatment and further prevention of facial trauma. The objective of this study was to understand the factors associated with the restoration of mastication, ocular, and nasal functions in the face of trauma victims, estimating their recovery time after surgical treatment. We analyzed 114 medical records of patients treated at the Hospital Montenegro, who attended follow-up consultations for up to 180 days. For analysis of the recovery time, we performed survival analysis, followed by COX analysis. We observed that half of the patients recovered their functions within 20 days. The average time for recovery from trauma in the zygomatic-orbital-malar-nasal complex was 11 days, and in the maxillary-mandibular complex, 21 days (HR: 1.5 [0.99 2.3], p = 0.055). Although functional reestablishment has reached high rates after the surgical approach, it is necessary to analyze the failing cases, as well as the economic impacts and the prevention strategies associated with facial trauma, to improve the service to the population.

RESUMO O entendimento da causa, da gravidade e do tempo decorrido para o restabelecimento das funções de lesões maxilofaciais pode contribuir para o estabelecimento de prioridades clínicas objetivando o efetivo tratamento e prevenção dos traumatismos de face. Assim, o objetivo deste estudo foi compreender quais os fatores associados ao restabelecimento das funções mastigatórias, oculares e nasais em vítimas de trauma de face, estimando o tempo para recuperação das funções, após o tratamento cirúrgico. Foram analisados 114 prontuários de pacientes atendidos no Hospital de Montenegro que compareceram às consultas de acompanhamento por até 180 dias. Para a análise do tempo para a recuperação, foi realizada a análise de sobrevida, seguida da análise de COX. Observou-se que metade dos pacientes recuperaram as funções em até 20 dias, sendo que o tempo médio para recuperação dos traumas no complexo zigomático-orbitário-malar-nasal foi de 11 dias e do complexo maxilo - mandibular de 21 dias (HR: 1,5 (0,99 - 2,3) p=0,055). Embora o restabelecimento das funções tenha atingido taxas elevadas após abordagem cirúrgicas, faz-se necessária a análise dos casos de insucessos bem como os impactos econômicos e as estratégias de prevenção associados aos traumas de face a fim de qualificar o serviço prestado à população.

Rinoplastia estética primaria cerrada. Revisiones durante tres años / Closed primary cosmetic rhinoplasty. Three years revisions

INTRODUCCIÓN Y OBJETIVO: Para conocer con más certeza, cuáles eran los problemas de nuestras rinoplastias primarias y el porcentaje de revisiones, buscamos y estudiamos los casos operados en un periodo de 3 años en nuestro Centro de Cirugía Estética. Creemos que este es un tema complejo que tiene pocos reportes en la literatura mundial dentro de la especialidad de Cirugía Plástica. MATERIAL Y MÉTODO: Analizamos retrospectivamente en un periodo de 3 años (2015-2017), cuál fue la proporción de rinoplastias primarias cerradas y las revisiones realizadas en ese mismo período, así como qué áreas de la nariz fueron las afectadas. Estudiamos las 4 zonas más frecuentemente sometidas a revisión, denominadas subunidades estéticas: dorso cartilaginoso, dorso óseo, punta y alas nasales y las látero-desviaciones nasales. Todas las revisiones se realizaron con una disección limitada, solo del área a tratar, con rinoplastia cerrada y con anestesia local. RESULTADOS: En el periodo estudiado realizamos 183 rinoplastias primarias de las cuales efectuamos 15 revisiones, lo que significa un porcentaje del 8.19%. Las revisiones más frecuentes fueron de la punta nasal y ala nasal. CONCLUSIONES: En nuestra experiencia, el porcentaje de revisiones obtenido fue comparable con el presentado en otras publicaciones sobre rinoplastia cerrada y abierta, considerando la creciente popularidad de las técnicas abiertas

BACKGROUND AND OBJECTIVE: In order to know our problems after primary rhinoplasty and our percentage of revisions, we studied the cases operated during 3 years in our outpatient Aesthetic Surgery Center. In our opinion, revision rhinoplasty is a complex issue with few reports in the international literature. METHODS: A retrospective study was conducted in a 3 year period (2015-2017) studying the proportion of primary closed rhinoplasty, the revisions made, and also the nasal areas affected. The 4 most frequent aesthetic subunits of review were identified: cartilaginous dorsum, bone humps, nasal tip and alar areas and nasal deviations. All revisions were performed using closed rhinoplasty techniques, local anesthesia and a limited dissection to the affected area. RESULTS: In that period, 183 primary rhinoplasties were performed and 15 revisions were carried out, which means a percentage of 8.19%. The most frequent areas were the nasal tip and the lateral alar areas. CONCLUSIONS: In our experience, the percentage of revisions was comparable to other reports about revisions in open and close rhinoplasties, considering the increased popularity of the open rhinoplasty

Treatment of naso-orbito-etmoidal Type III fracture in adolescents: case report / Tratamiento de la fractura naso-orbito-etmoidal Tipo III en adolescentes: relato de un caso

The naso-orbito-ethmoidal region is composed of delicate bones and when fractured may result in significant aesthetic-functional impairment. Diagnosis through clinical and imaging findings is extremely important for surgical planning. This study aims to report a case of type III fracture of the naso-orbito-ethmoidal region. Patient D.R.S., female, 13 years old, attended the emergency department of Hospital dos Fornecedores de Cana de Piracicaba (HFCP) - SP with complaint of pain in the fronto-nasal region and respiratory distress after trauma in face of baseball bat. Physical examination showed edema and short blunt injury in the region of the nasal dorsum and frontal region, bilateral periorbital hematoma, hyposphagma in right eye and traumatic telecanthus. When analyzing the computed tomography, it was observed fracture of the nasal bones, also affecting the medial wall of the orbit. The procedure was osteosynthesis of the fractures and reconstruction of the nasal dorsum. The fracture traces were exposed from coronal access, reduction of fractures and use of calvarial bone graft for nasal dorsum reconstruction. The fracture and the graft were fixed with plates of 1,6mm. Postoperative computed tomography analysis showed good graft positioning, but there was still a slight sinking of the left lateral wall of the nose. In a second moment another surgical intervention was done to reduce this wall and an internal containment device was installed. Currently the patient is in a state of observation and a follow-up period of 665 days. In cases of complex nasoorbito-ethmoidal fractures early diagnosis and treatment is essential to minimize sequelae and provide a better aesthetic and functional result.

La región etmoidal nasoorbital está compuesta de huesos delicados y, cuando se fractura, puede provocar una lesión estética-funcional significativa. El diagnóstico mediante hallazgos clínicos y de imagen es de suma importancia para la planificación quirúrgica. El paciente D.R.S., mujer, 13 años, leucoderma, asistió al servicio de emergencia del Hospital de Proveedores de Caña de Azúcar de Piracicaba quejándose de dolor en la región frontal-nasal y dificultad para respirar después de un traumatismo en la cara con un palo. El examen físico reveló edema y lesión contundente en el dorso nasal y la región frontal, hematoma periorbitario bilateral, hiposfagma del ojo derecho y telecanto traumático. Al analizar la tomografía computarizada se observó fractura de los huesosnasales en libro abierto, afectando también la pared medial de la órbita. El enfoque aplicado fue la osteosíntesis de fracturas y la reconstrucción del dorso nasal. Los rastros de fractura se expusieron del abordaje coronal, se redujeron las fracturas y se usaron injertos de casquete para reconstruir el dorso nasal. La fractura y el injerto se fijaron con placas de sistema de 1,6 mm y se realizó la cantopexia de los ligamentos cantales mediales. Se requirió cirugía reparadora secundaria para la corrección de la pared lateral de la nariz, que persistió en el postoperatorio. Actualmente el paciente se encuentra en un estado de conservación y período de seguimiento de 665 días. En casos de fracturas nasoorbitales-etmoidales complejas, el diagnóstico y el tratamiento tempranos son esenciales para minimizar las secuelas y proporcionar un mejor resultado estético y funcional.

Frontoethmoidal encephalocele. Report of a case / Encefalocele frontoetmoidal. A propósito de un caso

Encephaloceles are uncommon in western countries and most cases are located in the occipital bone. Frontal encephaloceles may involve the ethmoid bone, nasal bones and/or the orbits. Surgical repair is complex and usually requires a multidisciplinary approach. The goal of the surgery is to reconstruct the normal anatomy, to achieve a good cosmetic repair and to avoid a cerebrospinal fluid leak. We present a case of a patient with a large congenital frontoethmoidal encephalocele. Autologous calvarian bone grafts were used to repair of encephalocele defect and for the reconstruction of the frontonasal area. The defect closure and the cosmetic result were satisfactory, and the only complication detected was the infection of a previously performed ventriculoperitoneal shunt. A description of the technique and a review of the literature are presented

Los encefaloceles son infrecuentes en los países occidentales y su localización más frecuente es occipital. Los encefaloceles frontales pueden afectar hueso etmoidal, frontal y/o órbitas. La reparación quirúrgica es compleja y habitualmente precisa de un abordaje multidisciplinar. El objetivo de la cirugía es reconstruir la anatomía del paciente con un buen resultado estético, y evitar la fístula de líquido cefalorraquídeo. Se presenta un caso de un gran encefalocele frontoetmoidal. El encefalocele fue reparado y la reconstrucción ósea se realizó con hueso autólogo de la capota craneal. El cierre y el resultado cosmético fueron buenos y la única complicación fue una infección posquirúrgica. Se describe la técnica y se revisa la literatura publicada al respecto

Hemangioma cavernoso de huesos propios de la nariz: a propósito de un caso / Cavernous hemangioma of the nasal bones: a case report

Los hemangiomas cavernosos representan menos del 1% de todos los tumores óseos, siendo las vértebras y el cráneo las localizaciones más habituales. Estos tumores son extremadamente raros en los huesos de la nariz, con muy pocos casos publicados en la literatura médica, descritos en cornetes, vómer, huesos propios o lamina erpendicular del etmoides. Suelen presentarse como una lesión tumoral que crece con el tiempo, implicando al hueso e incluso a tejidos blandos, pudiendo causar complicaciones como obstrucción nasal, sangrado, ulceraciones e infección, entre otras. Presentamos el caso de un paciente de 37 años con un hemangioma cavernoso localizado en los huesos propios de la nariz, revisándose los aspectos más destacados de este raro tumor

Cavernous hemangiomas represent less than 1% of all bone tumours, with the vertebrae and the skull being the most common locations. These tumours are extremely rare in the bones of the nose, with very few cases published in the medical literature, where they have been reported in turbinates, vomer, nasal bones or perpendicular lamina of the ethmoid. They usually present as a tumour lesion that grows over time, involving the bone and even the soft tissues, which can cause complications such as nasal obstruction, bleeding, ulcerations and infection. We present the case of a 37 year old patient with a cavernous hemangioma located in the bones of the nose, reviewing the most notable aspects of this rare tumour

Histopathological comparison of bone healing effects of endonasal and percutaneous lateral osteotomy methods in rabbit rhinoplasty model / Comparação histopatológica dos efeitos da cicatrização óssea entre as técnicas de osteotomia lateral endonasal e percutânea em modelo de rinoplastia em coelhos

Abstract Introduction: Lateral osteotomy is mainly performed either endonasally or percutaneously in rhinoplasty which is a frequently performed operation for the correction of nasal deformities. Both techniques have both advantages and disadvantages relative to each other. Objective: The aim of this study was to compare the histopathological effects of endonasal and percutaneous osteotomy techniques performed in rhinoplasty on bone healing and nasal stability in an experimental animal model. Methods: Eight one year-old New Zealand white rabbits were included. Xylazine hydrocloride and intramuscular ketamine anesthesia were administered to the rabbits. Endonasal osteotomy (8 bones) was performed in Group 1 (n = 4), and percutaneous osteotomy (8 bones) in Group 2 (n = 4). One month later the rabbits were sacrificed. Bone healing of the rabbits was staged according to the bone healing score of Huddleston et al. In both groups, nasal bone integrity was assessed subjectively. Results: In the percutaneous osteotomy group, Grade 1 bone healing was observed in two samples (25%), Grade 2 bone healing in two samples (25%), Grade 3 bone healing in four samples (50%). In the endonasal osteotomy group, Grade 1 bone healing was observed in 6 samples (75%) and Grade 2 bone healing was observed in 2 samples (25%). In the percutaneous group, fibrous tissue was observed in 2, predominantly fibrous tissue and a lesser amount of cartilage was observed in 2 and an equal amount of fibrous tissue and cartilage was observed in 4 samples. In the endonasal group, fibrous tissue was observed in 6 samples, and predominantly fibrous tissue with a lesser amount of cartilage was observed in 2 samples. In both groups, when manual force was applied to the nasal bones, subjectively the same resistance was observed. Conclusion: Percutaneous lateral osteotomy technique was found to result in less bone and periost trauma and better bone healing compared to the endonasal osteotomy technique.

Resumo Introdução: Nas rinoplastias, a osteotomia lateral é realizada principalmente por via endonasal ou percutânea para correção de deformidades nasais. Ambas as técnicas apresentam vantagens e desvantagens. Objetivo: Comparar os efeitos histopatológicos sobre a cicatrização óssea e estabilidade nasal entre as técnicas de osteotomia endonasal e percutânea em rinoplastia em um modelo animal experimental. Método: Foram incluídos oito coelhos brancos da Nova Zelândia de um ano de idade. Hidrocloreto de xilazina e cetamina intramuscular foram administrados aos coelhos como agentes anestésicos. Osteotomia endonasal (8 ossos) foi realizada no Grupo 1 (n = 4) e osteotomia percutânea (8 ossos) no Grupo 2 (n = 4). Um mês depois, os coelhos foram sacrificados. A cicatrização óssea dos coelhos foi avaliada de acordo com o escore de cicatrização óssea de Huddleston et al. Em ambos os grupos, a integridade do osso nasal foi avaliada subjetivamente. Resultados: No grupo da osteotomia percutânea, observou-se cicatrização óssea de grau 1 em duas amostras (25%), cicatrização óssea de grau 2 em duas amostras (25%), e cicatrização óssea de grau 3 em quatro amostras (50%). No grupo da osteotomia endonasal, observou-se cicatrização óssea de grau 1 em 6 amostras (75%) e a cicatrização óssea de grau 2 foi observada em 2 amostras (25%). No grupo percutâneo, o tecido fibroso foi observado em 2 amostras, enquanto tecido predominantemente fibroso e uma menor quantidade de cartilagem foi observada em 2 e uma quantidade igual de tecido fibroso e cartilagem foi observada em 4 amostras. No grupo endonasal, observou-se tecido fibroso em 6 amostras e tecido predominantemente fibroso com uma menor quantidade de cartilagem em 2 amostras. Em ambos os grupos, quando força manual foi aplicada aos ossos nasais, a mesma resistência foi observada subjetivamente. Conclusão: A técnica de osteotomia lateral percutânea resultou em menor traumatismo ósseo e periosteal e melhor cicatrização óssea em comparação com a técnica de osteotomia endonasal.

Correção do dorso nasal baixo ou em sela com enxerto composto de cartilagem conchal fragmentada fixa ao pericôndrio envolvidos à fáscia da mastóide / Correction of low or saddle nasal dorsum with a composite graft of fragmented conchal cartilage fixed to the perichondrium wrapped in mastoid fascia

Introdução: A rinoplastia de aumento em muitos casos torna-se mais difícil que a rinoplastia de redução. Enxertos dorsais sólidos realizados com cartilagem costal têm sido muito utilizados para aumento dorsal, porém estão associados com altos índices de revisão, por isso, muitos autores passaram a utilizar cartilagem em cubos envoltos por fáscia. A fáscia da mastoide, conectada ao pericôndrio da cartilagem conchal auricular, pode formar um enxerto composto para o aumento do dorso nasal, sendo também uma opção de tratamento. O objetivo é demonstrar a possibilidade do uso de cartilagem da concha auricular fragmentada fixa ao seu pericôndrio, e envoltos na fáscia da mastoide, formando um enxerto composto para aumento do dorso nasal. Métodos: Tratase de um estudo retrospectivo de 9 pacientes operados entre 2012 e 2016 no Hospital de Base da Faculdade de Medicina de São José do Rio Preto, em que foi realizado aumento do dorso nasal com cartilagem conchal fragmentada fixa ao seu pericôndrio e envolto à fáscia da mastoide. Resultados: Os pacientes foram acompanhados de 6 a 48 meses. Foram questionados quanto à satisfação do procedimento nasal e sensibilidade auricular, com avaliação positiva dos pacientes e cirurgiões. Conclusão: A cartilagem conchal parece ser uma alternativa de grande valia para procedimentos de aumento de dorso nasal. Esta cartilagem envolta com fáscia da mastoide parece ser uma alternativa vantajosa em comparação ao uso de outras fáscias, com baixa morbidade e taxa de complicações, podendo ser uma grande opção para tratamento do nariz em sela.

Introduction: In many cases, augmentation rhinoplasty is more difficult than reduction rhinoplasty. Solid dorsal grafts performed with costal cartilage have been widely used for dorsal augmentation; however, they are associated with high rates of revision. Thus, many authors began to use cartilage cut into cubes wrapped in fascia. The mastoid fascia, connected to the perichondrium of the auricular conchal cartilage can form a composite graft to augment the nasal dorsum, which is also a treatment option. The objective is to demonstrate the possibility of using fragmented auricular conchal cartilage fixed to its perichondrium and wrapped in mastoid fascia to form a composite graft for augmentation of the nasal dorsum. Methods: This is a retrospective study of 9 patients who underwent operation between 2012 and 2016 at the Base Hospital of the Faculty of Medicine of São José do Rio Preto, in which the nasal dorsum was augmented with fragmented conchal cartilage fixed to its perichondrium and wrapped in the mastoid fascia. Results: The patients were followed up for up 6 to 48 months. They were questioned about their satisfaction with the nasal procedure and hearing sensitivity, and provided a positive evaluation of the surgeons. Conclusion: The conchal cartilage seems a highly valuable alternative graft for nasal dorsum augmentation procedures. The technique of using cartilage wrapped in mastoid fascia seems to be an advantageous alternative when compared with those using cartilage wrapped in other fasciae: it has low morbidity and complications rates and can be a great option for saddle nose treatment.

Introducción. Cuando un paciente se encuentra politraumatizado, involucrando fracturas serias en la región maxilofacial, así como en la base del cráneo, se opta por realizar una traqueostomía con el fin de permitir un abordaje simultáneo para los diferentes tercios faciales afectados. La intubación submental ofrece una alternativa a dicho manejo de la vía aérea, significando menor riesgo para el paciente por su seguridad y versatilidad en el manejo de las fracturas nasales y el establecimiento de la oclusión. Materiales. Un total de 30 pacientes con diferente afección de los tercios faciales (superior, medio e inferior) fueron tratados por nuestro equipo, llevando a cabo una intubación submental para mantener la vía aérea. Las fracturas afectaban los huesos nasales y la oclusión dentaria. Resultados. En todos los casos se logró una adecuada reducción de las fracturas nasales y obtención de la oclusión dental correcta, sin presentar eventualidades durante o después de la intubación mencionada. Conclusiones. La intubación submental es una buena alternativa para poder tratar adecuadamente a los pacientes politraumatizados con afección de la cavidad nasal y oral sin tener que realizar una traqueostomía en casos que no la requieran (AU)

Introduction. When a patient has multiple injuries, involving serious fractures in the maxillofacial region and base of skull, a tracheostomy is often performed to approach the different affected facial thirds simultaneously. Submental intubation offers an alternative to this type of airway management, involving a decreased risk for the patient due to its safety and versatility in treating nasal fractures and re-establishment of dental occlusion. Materials. A total of 30 patients with different degrees of involvement of the facial thirds (superior, middle and inferior) were treated by our team, performing a submental intubation to maintain the airway. These fractures affected nasal bones and dental occlusion. Results. In all cases we accomplished an adequate reduction of nasal fractures and obtained an accurate dental occlusion, with no incidents during or after this intubation. Conclusions. Submental intubation is a good alternative to treat multiple injury patients who have nasal and oral cavities involvement, avoiding the use of tracheostomy in cases that do not need it (AU)

Applicability and Effectiveness of Closed Reduction of Nasal Fractures under Local Anesthesia

Introduction: A significant portion of patients treated in emergency departments have nasal fracture. It is important that the otolaryngologist know how to treat such damage. Objectives To evaluate the effectiveness of nasal fracture reduction under local anesthesia and tolerance to the procedure. Methods: Twenty-four patients treated in the emergency department with closed reduction under local anesthesia were prospectively followed. Epidemiologic information and data regarding pain and complications during the management were noted. The degree of satisfaction was researched by visual analog scale. Results: The majority of patients were male (75%), and the most common cause of injury was motor vehicle accident. We found a significant association between time to reduction and referred pain during the procedure. In patients in whom the procedure was delayed (over 3 days), there was less pain, and those who bled during the procedure had a shorter average time to reduction than the group of patients who did not bleed. Most patients were very satisfied, with more than 95% of these willing to undergo the same process again, if necessary. Conclusions: The closed approach in the clinic under local anesthesia was effective and safe in restoration of the nose...

Epidemiologia dos traumas de face do serviço de cirurgia plástica e queimados da Santa Casa de Misericórdia de São José do Rio Preto / Epidemiology of facial trauma at the plastic surgery and burns service of the Santa Casa de Misericórdia de São José do Rio Preto

Introdução: O trauma é um dos principais problemas de saúde pública em todos os países, sendo os que acometem a região facial muito frequentes. O presente trabalho objetiva avaliar dados epidemiológicos de pacientes que sofreram trauma de face com fratura. Métodos: Estudo epidemiológico realizado por meio dos prontuários de 92 pacientes. Foram selecionados indivíduos com trauma facial de qualquer intensidade, no período de janeiro de 2009 a janeiro de 2013, e agrupados de acordo com a etiologia e a localização das fraturas. Os dados coletados foram apresentados em valores absolutos e porcentagens. Resultados: Houve prevalência de pacientes do sexo masculino. A etiologia do trauma de face mais encontrada foi a violência interpessoal, observada na maioria dos grupos, exceto naquele acima de 45 anos, cuja predominância etiológica foi de queda e acidente de automóvel. A incidência das causas variou de acordo com a faixa etária: < 18 anos, de 19 a 25 anos, de 26 a 35 anos, de 36 a 45 anos e > 45 anos. Setenta e cinco por cento das fraturas de mandíbula foram unilaterais e 25%, bilaterais. O tratamento cirúrgico de fixação com placas foi o mais utilizado. No nosso estudo, catorze pacientes apresentaram complicação pós-cirúrgica. Conclusão: Há necessidade de um atendimento sistematizado para os traumas faciais. A variação na faixa etária encontrada entre os pacientes estudados demonstra que o trauma facial abrange indivíduos em qualquer idade, embora seja maior entre os jovens. Acreditamos que o presente estudo epidemiológico possibilitará a melhora da qualidade no atendimento aos pacientes com trauma facial.

Introduction: Trauma is a major public health problem in all countries, and injuries involving the facial region are very common. This study aims to assess the epidemiological data of patients who suffered facial trauma with fracture. Methods: Epidemiological study conducted on 92 patient records. Individuals with facial trauma of any intensity presenting between January 2009 and January 2013 were selected and grouped according to the etiology and location of fractures. Data were presented as absolute values and percentages. Results: There was a higher prevalence of male patients. The most frequent cause of facial trauma was interpersonal violence in most groups, except for those over 45 years old, for whom the predominant causes were falls and car accidents. The frequency of the causes varied according to age: <18 years, 19-25 years old, 26-35 years old, 36-45 years and> 45 years. Seventy-five percent of mandibular fractures were unilateral and 25% bilateral. Surgical fixation with plates was the most common treatment. In our study, fourteen patients had postoperative complications. Conclusion: There is a need for systemized care for facial trauma. The variation in the age range found among the studied patients demonstrates that facial trauma includes individuals of any age, although it is more common among young people. We believe that this epidemiological study will enable the improvement of the quality of care for patients with facial trauma.

Tratamento estético da columela nasal: columela oculta e columela pendente / Aesthetic treatment of retracted and hanging nasal columellas

Os autores revelam, no presente trabalho, suas abordagens frente às alterações estéticas da columela nasal, mais observadas em sua prática clínica, a columela oculta e a columela pendente. Para a columela oculta os autores descrevem o uso de um retalho condro-mucopericondral do septo nasal como escolha preferencial. Para o tratamento da columela pendente os autores utilizam as abordagens, direta e indireta, descritas por Randall, nos casos leves a moderados, e para os casos mais acentuados utilizam uma associação de táticas além de uma modificação do que é descrito por Armstrong e Joseph. Suas opções de tratamento são confrontadas com o que há descrito na literatura da especialidade e seus resultados comparativos são apresentados.

This study discusses approaches for aesthetic correction of nasal columellas, i.e. retracted and hanging columellas, most commonly observed in clinical practice. We describe a chondral-mucoperichondrial nasal septal flap and direct or indirect approaches described by Randall as our preferred procedures to correct retracted and mild to moderate hanging columella, respectively. A combination of procedures is used in more severe cases, in addition to modified Armstrong and Joseph's approaches. These treatment options are compared to other literature reports on this specialty.
