ABSTRACT

Aim: The mandible is regarded as a frequently fractured bone in patients who present with maxillofacial trauma accounting for almost 15.5% to 59% of all facial fractures. Managing condylar trauma has remained to be a point of contention amongst experts, regardless of the advances in surgical modalities and methodologies, and the treatment plan is often determined by the preference and the experience of the surgeon. There exist various approaches in the literature, each with its own specific benefits and drawbacks. With this study, we aimed to evaluate the prevalence of post-operative complications in patients who experienced ORIF by means of the retromandibular approach, by comparing the outcomes of one group having undergone transparotid surgery, with another that underwent retroparotid surgery. Methods: An experimental trial was undertaken. Convenience sampling was done from among the cases of condylar neck and base fracture visiting the department of OMFS, Dow University of Health Sciences from January 2017 to December 2019. An overall 26 patients were divided into 2 groups of 13 members each; one was managed using Open Reduction Internal Fixation (ORIF) by means of a retromandibular transparotid approach while the other group was treated with ORIF by means of a retromandibular retroparotid approach. A 6 month follow-up was done to assess range of active motion, occlusion, and complications such as deviation/deflection, neural injury, infections, sialocele, salivary fistulae and Frey's syndrome in both groups. Results: There was no statistically significant difference between the two groups in terms of inter-incisal opening, right and left lateral movements, or protrusion. One patient in the retroparotid group had deviation on mouth opening (7.69%), while one in the transparotid group reported with infection (7.69%), and 2 developed post operative seromas (15.38%). None had persisting facial nerve palsy at 6 months. Conclusion: We find no significant disparity between the 2 approaches at a follow-up of 6 months; therefore, the primary determining factor for selection of either technique is surgeon preference and appropriate case selection

ABSTRACT

Aim: Maxillofacial fractures occur frequently in the general population, and sports-related fractures represent some of these cases. However, few studies have been carried out in Brazilian populations aimed at sports-related maxillofacial fractures. This study assessed the demographic and fracture characteristics of patients with sports-related maxillofacial fractures who were seen at a Brazilian trauma care center. Methods: Medical records of patients with a history of sports-related maxillofacial fractures treated between January 2018 and December 2019 were retrospectively evaluated. Personal data, fracture characteristics, sport type, treatment performed and need for hospitalization were collected. The data were subjected to statistical analyses with likelihood ratio test using the Statistical Package for Social Sciences (SPSS) 25.0 (p ≤ 0.050). Results: Forty cases (4.96% of the total) of facial fractures were included. The mean age was 24.9 (± 9.8) years, with a predominance of males (92.5%). The use of protective equipment was rare. The most frequently involved sport modality was soccer (47.5%), followed by cycling (27.5%). The most frequent fracture location was nose (45%), followed by mandible (25%) and zygomatic complex (17.5%). Soccer was responsible for most nose fractures (61.1%), while cycling caused the majority of mandibular fractures (60%). Conservative treatment predominated (60%). There was only a significant difference between fracture location and the need for hospitalization (p = 0.021). Conclusion: Patients with sportsrelated maxillofacial fractures were typically young adult males, the injury was more often located in the nose and mandible and related to soccer or cycling. The use of protective equipment must be reinforced

ABSTRACT

Aim: Evaluation of the reliability of 3D computed tomography (3D-CT) in the diagnosis of mandibular fractures. Methods: A cross-sectional, quantitative and qualitative study was carried out, through the application of a questionnaire for 70 professionals in the area of Oral and Maxillofacial Surgery and Radiology. 3D-CT images of mandibular fractures were delivered to the interviewees along with a questionnaire. Participants answered about the number of traces, the region and the type of fracture. The correct diagnosis, that is, the expected answer, was based on the reports of a specialist in oral and maxillofacial radiology after viewing the images in the axial, sagittal and coronal sections. The resulting data from the interviewees was compared with the expected answer and then, the data was analyzed statistically. Results: In the sample 56.9% were between 22 and 30 years old, 52.8% were oral and maxillofacial surgeons (OMF), 34.7% were residents in OMF surgery and 12.5% OMF radiologists. Each professional answered 15 questions (related to five patients) and 50.8% of the total of these was answered correctly. Specialists in Oral and Maxillofacial Surgery and Traumatology correctly answered 53.9%. Interviewees with experience between 6 and 10 years correctly answered 58.2%. In identifying fracture traces, 46.1% of the questions were answered correctly. In terms of location, 5.6% of interviewees answered wrongly while 14.2% answered wrongly regarding classification. Conclusion: 3D computed tomography did not prove to be a reliable image for diagnosing mandibular fractures when used alone. This made necessary an association with axial, sagittal and coronal tomographic sections

ABSTRACT

Introdução: Por sua posição na face, a mandíbula é frequentemente atingida pelos traumas, surgindo em algumas estatísticas como o osso fraturado com maior incidência em face. Em fraturas de mandíbulas atróficas o tratamento conservador, com fixação intermaxilar não costuma ser uma opção viável pela falta de dentes e pequena área de contato ósseo existente. Dessa forma, a redução aberta e fixação interna estável tem sido o tratamento de escolha sempre que a condição do paciente permitir. Objetivo: relatar um caso de osteossíntese de fratura de mandíbula atrófica por acesso extraoral. Relato de caso: Paciente 64 anos, faioderma, sexo feminino, procurou o serviço de Cirurgia e Traumatologia Bucomaxilofacial da Universidade Federal da Bahia apresentando traumatismo facial por queda da própria altura, referindo severas queixas álgicas espontâneas em região mandibular. Ao exame físico notou-se edentulismo total em ambas as arcadas, edema, hematoma e degrau ósseo á palpação em região de corpo de mandíbula a direita, alémde mobilidade atípica a manipulação da mandíbula. Ao exame de imagem notou-se sinais de fratura em corpo mandibular direito e côndilo esquerdo. O tratamento instituído foiconservador para a fratura de côndilo e cirúrgico para a fratura de corpo, o acesso foi extraoral ea fixação rígida foi realizada com placa e parafusos dos dispositivos Load-Bearing. Considerações finais: A paciente não apresentou quaisquer déficits funcionais pós-procedimento cirúrgico, sendo o tratamento abertocom fixação interna estável bastante promissor por restabelecer a união de focos fraturados e deslocados, proporcionando estabilidade da fratura e conforto imediato para a paciente(AU)


Introduction: Due to its position on the face, the jaw is frequently affected by trauma, appearing in some statistics as the fractured bone with a higher incidence in the face. In fractures of atrophic jaws, conservative treatment, with intermaxillary fixation, is not usually a viable option due to the lack of teeth and small area of existing bone contact. Thus, open reduction and stable internal fixation have been the treatment of choice whenever the patient's condition permits. Objective: to report a case of osteosynthesis of atrophic mandible fracture through extraoral access. Case report: Patient 64-year-old, female, sought the service of Maxillofacial Surgery and Traumatology at the Federal University of Bahia presenting facial trauma due to falling from his own height, referring to severe spontaneous pain complaints in the mandibular region. On physical examination, total edentulism was noted in both arches, edema, hematoma and bone step on palpation in the right jaw body region, in addition to atypical mobility in the jaw manipulation. On imaging examination, signs of fracture were noted in the right mandibular body and left condyle. The treatment instituted was conservative for condyle fracture and surgical for body fracture, access was extraoral and rigid fixation was performed with plate and screws of the Load-Bearing devices. Final considerations: The patient did not presente any functional deficits after the surgical procedure, and the open treatment with stable internal fixation is very promising for restoring the union of fractured and displaced foci, providing fracture stability and immediate comfort for the patient(AU)

ABSTRACT

Introduction: Facial injuries are a common occurrence at the emergency room. Treatment for this type of trauma is complex in terms of re-establishing good oral and facial function, plus aesthetics. Objective: This paper aims to report a clinical case of aesthetic and functional rehabilitation using triamcinolone in a patient affected on the face by a fireworks explosion. Case report: A 26-year-old man was admitted to the oral and maxillofacial surgery service of the Sergipe Urgency Hospital presenting trauma after the explosion of a "Firework rocket" in his face. The patient had extensive soft tissue injury in gingival mucosa, right labial commissure, and tongue. There was also inferior incisive avulsion and dentoalveolar fracture. His clinical and tomographic evaluation presented comminuted mandibular fracture. After eighteen days he was discharged and sent to the dentistry service of the Federal University of Sergipe for aesthetic and functional rehabilitation of his facial damages. Two months later, the patient attended a University dental service to begin aesthetic and postoperative functional rehabilitation. First, the necrotic bone was removed, following intralesional infiltration of hexacetonide triamcinolone 20mg/mL into the scar of the labial region and the commissure of the lips was performed. Each application was performed after twenty days of interval. Later, lingual frenectomy and glossosplasty were done for improving his lingual mobility and then hexacetonide triamcinolone 20mg/mL infiltrations were also done in the tongue base in the following sessions. Conclusions: After five infiltrations, it was observed an improvement in the scar appearance and texture, which also had a lower contracture, as well as a lingual motricity improvement(AU)


Introducción: Las lesiones faciales son frecuentes en el servicio de emergencia. El tratamiento para este tipo de trauma es complejo en términos de restablecer una buena función bucal y facial, además de la estética. Objetivo: Reportar un caso clínico de rehabilitación estética y funcional a través del uso de hexacetónido de triamcinolona en un paciente afectado por una explosión de fuegos artificiales en su rostro. Caso clínico: Hombre de 26 años ingresado en el servicio de cirugía oral y maxilofacial del Hospital de Urgencia de Sergipe por presentar un traumatismo después de la explosión contra su rostro de un cohete de fuegos artificiales. El paciente tenía una lesión extensa de partes blandas en la mucosa gingival, comisura labial derecha y lengua. También hubo avulsión incisiva inferior y fractura dentoalveolar. A través de la evaluación clínica y de tomografía, fue posible observar fragmentación múltiple ósea en el sitio de la fractura, compatible con fractura mandibular conminuta. Después de dieciocho días fue dado de alta y enviado al servicio de odontología de la Universidad Federal de Sergipe para la rehabilitación estética y funcional de sus daños faciales. Dos meses después, el paciente asistió al servicio dental de la universidad para comenzar la rehabilitación funcional estética y posoperatoria. Primero, se retiró el hueso necrótico, luego se realizó la infiltración intralesional de hexacetónido de triamcinolona 20 mg/mL en la cicatriz de la región labial y se realizó la comisura de los labios; con un intervalo de 20 días entre cada aplicación. Posteriormente, se realizaron frenectomía lingual y glososplastia, para mejorar su movilidad lingual, y luego se realizaron infiltraciones de 20 mg/mL de hexacetónido de triamcinolona en la base de la lengua en las sesiones siguientes. Comentarios principales: Después de cinco infiltraciones se observó una mejora en el aspecto y la textura de la cicatriz, que también tenía una contractura más baja, así como una mejora de la motricidad lingual(AU)

ABSTRACT

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.

ABSTRACT

ABSTRACT Purpose: to evaluate the occurrence of loss of sensitivity of the inferior alveolar nerve, and to monitor the remission of this change in patients with mandibular fractures subjected to surgical treatment. Methods: patients with mandibular fractures, surgically treated within one year, were prospectively evaluated. Data regarding etiology, fracture location, type and displacement, and surgical access, were obtained. The tactile and thermal tests were applied at eighteen points in the mental region, within a period of six months. Statistical tests were applied to compare the categories of variables and the period of observation (p ≤ 0.050). Results: during the study, 37 patients were included. There were 24 bilateral and 13 unilateral fractures. Sensory changes occurred in 56.8% of the patients in the preoperative period, in 83.8% of the patients, in the postoperative period, and 35.1% of the patients presented complete remission during the final period of the study. Conclusion: sensory changes occurred in about half of the patients, due to the fracture, increasing greatly in the postoperative period, with complete remission in about one third of the cases. The fracture type, degree of displacement and surgical access type influenced the occurrence of sensory alterations.

ABSTRACT

Introdução: O trauma decorrente de causas externas é um problema de saúde em várias regiões do mundo. Além de altos índices de mortalidade e morbidade, os traumas de face resultam em impactos estéticos, estruturais e psicológicos na vida do indivíduo e na sociedade, gerando, também, um alto custo com gastos hospitalares. Objetivo: Relatar o caso de um paciente com trauma de face por acidente ciclístico, com alterações na funcionalidade do sistema estomatognático. Metodologia: Foi realizada avaliação fonoaudiológica por meio do Protocolo de Avaliação Preliminar (PAP), para observação do aspecto das estruturas orais, funções do sistema estomatognático, voz e reflexos protetivos de vias aéreas superiores. Na sequência, foi aplicado o Protocolo de Avaliação do Risco para Disfagia (PARD), para avaliação direta da deglutição. Resultados: Na avaliação dos órgãos fonoarticulatórios foi observado alterações de sensibilidade, mobilidade e redução significativa de força. Na avaliação direta da deglutição foi observada dificuldade na captação do alimento, escape anterior de alimento, elevação laríngea reduzida e múltiplas deglutições. Conclusão: O paciente foi classificado com Disfagia Orofaríngea leve a moderada, mantendo dieta via oral com consistência adaptada e orientação para continuidade de terapia fonoaudiológica. Devido ao alto número de casos semelhantes ao relatado nos hospitais de urgência e emergência, constata-se a necessidade de avaliação do sistema estomatognático para promover a melhor abordagem aos pacientes com trauma de face


Introduction: Trauma due to external causes is a health problem in several regions of the world. In addition to high rates of mortality and morbidity, facial traumas result in aesthetic, structural and psychological impacts on the individual's life and on society, also generating a high cost of hospital expenses. Objective: Report the case of a patient with facial trauma due to a cycling accident, with changes in the functionality of the stomatognathic system. Methodology: Speech therapy evaluation was carried out through the Preliminary Evaluation Protocol, to observe the appearance of oral structures, functions of the stomatognathic system, voice and protective reflexes of the upper airways. Then, the Risk Assessment Protocol for Dysphagia was applied, for direct swallowing assessment. Results: In the evaluation of Organs phonoarticulatory organs, changes in sensitivity, mobility and significant reduction in strength were observed. In the direct evaluation of swallowing, difficulty in capturing food, previous escape of food, reduced laryngeal elevation and multiple swallowing were observed. Conclusion: The patient was classified with Mild to Moderate Oropharyngeal Dysphagia, maintaining an oral diet with consistency adapted and guidance for continuing speech therapy. Due to the high number of cases similar to that reported in urgent and emergency hospitals, there is a need to evaluate the stomatognathic system to promote the best approach to patients with facial trauma.

ABSTRACT

RESUMEN: Introducción: Las fracturas mandibulares producen serias comorbilidades, alteraciones en la función, calidad de vida entre otros. Existen distintas alternativas quirúrgicas en las fracturas favorables de ángulo mandibular, siendo las más utilizadas las técnicas de estabilización mediante miniplacas de titanio. No existe consenso sobre si es más efectivo y seguro utilizar una o dos miniplacas de titanio. Métodos: Realizamos una búsqueda en Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud, la cual es mantenida mediante el cribado de múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, analizamos los datos de los estudios primarios, realizamos un metanálisis y preparamos una tabla de resumen de los resultados utilizando el método GRADE. Resultados y conclusiones: Identificamos 7 revisiones sistemáticas que en conjunto incluyeron 17 estudios primarios, de los cuales 3 son ensayos aleatorizados. Concluimos que el tratamiento de estabilización mediante una miniplaca de titanio probablemente disminuye el riesgo de paresia facial. Por otro lado, el uso de una miniplaca podría aumentar el riesgo de dehiscencia de la herida quirúrgica, disminuir el riesgo de reintervención quirúrgica y podría resultar en poca o nula diferencia en el riesgo de maloclusión, pero la certeza de la evidencia es baja. No está claro si el uso de una en comparación con dos miniplacas de titanio reduce el riesgo de infección y parestesia ya que la certeza de la evidencia disponible es muy baja.


ABSTRACT: Introduction: Mandibular fractures produce severe comorbidities, functional alterations, changes in the quality of life, among others. There are different surgical alternatives for favorable mandibular angle fractures; the most used is the stabilization techniques using titanium miniplates. There is no consensus on which it is more effective and safe; use one or two titanium miniplates. Methods: We searched in Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. Results and conclusions: We identified seven systematic reviews that included 17 primary studies, in which three were randomized trials. We conclude that stabilization treatment with a titanium miniplate probably reduces the risk of facial paresis. On the other hand, the use of a miniplate could increase the risk of dehiscence of the surgical wound, decrease the risk of reoperation, and could result in little or no difference in the risk of malocclusion, but the certainty of the evidence is low. It is not clear whether the use of one compared to two titanium miniplates reduces the risk of infection and paresthesia since the certainty of the available evidence is very low.

ABSTRACT

Introdução: A face é uma região exposta a diversos traumas que são causados por várias etiologias, dentre eles por projétil de arma de fogo que são a segunda maior causa de fraturas perdendo somente para os acidentes automobilísticos. As fraturas acometem com frequência a região mandibular, por ser um osso de destaque na face devido sua proeminência. O objetivo deste trabalho é elucidar uma fratura cominutiva na região de côndilo e colo mandibular causada por ferimento de arma de fogo e seu respectivo tratamento. Relato de Caso: Paciente de 25 anos, compareceu a um serviço de atendimento de cirurgia bucomaxilofacial vítima de um ferimento por arma de fogo. Após a realização dos exames de imagem constatou-se que o projétil estava alojado no pescoço da vítima, causando a fratura cominutiva o ramo e o côndilo mandibular do lado esquerdo. A paciente foi submetida a anestesia geral para realização da osteossíntese da fratura. Considerações finais: O diagnóstico e o tratamento são realizados por uma equipe multidisciplinar para que o tratamento seja o mais correto e efetivo, com finalidade de minimizar morbidades e mortalidades, já que os pacientes sobrevivem com sequelas permanentes quando o diagnóstico e o tratamento não são realizados de forma correta... (AU)


Introduction: The face is a region exposed to several traumas that are caused by several etiologies, among them a firearm projectile that is the second major cause of fractures losing only to automobile accidents. The fractures frequently affect the mandibular region, as it is a prominent bone in the face due to its prominence. The purpose of this study is to elucidate a comminuted fracture in the condyle and mandibular neck region caused by a firearm injury and its respective treatment. Case Report: A 25-year-old patient who attended a buccomaxillofacial surgery service as a victim of a gunshot wound. After imaging examinations it was found that the projectile was lodged in the victim's neck, causing the comminuted fracture of the branch and mandibular condyle on the left side. The patient underwent general anesthesia to perform the fracture osteosynthesis. Final considerations: Diagnosis and treatment are performed by a multidisciplinary team so that treatment is the most correct and effective, in order to minimize morbidities and mortalities, since patients survive with permanent sequelae when diagnosis and treatment are not performed correctly...

ABSTRACT

Stability is necessary to ensuring proper bone repair after osteotomies and fractures. The aim of this research was to analyze how the repair of pseudoarthrosis sites was affected by different conditions in related to soft tissue. An experimental study was designed with 18 New Zealand rabbits. Six study groups were formed. An osteotomy was performed on the mandibular body of each animal and muscle was installed at the osteotomy site to model pseudoarthrosis. Fixation by surgery was then carried out, using plates and screws. The animals were submitted to euthanasia after 21, 42 and 63 days to make a descriptive comparison of the histological results. No animal was lost during the experiment. In all the samples, bone formation was observed with different degrees of progress. Defects treated with or without removal of the tissue involved in pseudoarthrosis presented comparable bone repair, showing that stability of the bone segments allows the repair of adjacent tissue. In some samples cartilaginous tissue was associated with greater bone formation. Stabilization of the fracture is the key in bone repair; repair occurs whether or not the pseudoarthrosis tissue is removed.


La estabilidad de las osteotomías y de las fracturas son fundamentales para asegurar la adecuada reparación ósea; el objetivo de esta investigación fue analizar la reparación presente en sitios de pseudoartrosis realizando la limpieza de la zona previo a la fijación o manteniendo el tejido de la nounión en el mismo lugar durante la osteosíntesis. Se diseñó un estudio experimental incluyendo 18 conejos de raza Neozelandesa. Se formaron 6 grupos de estudios a quienes se relizó una osteotomía en el cuerpo mandibular y posterior instalación de músculo en el lugar de la osteotomía para fabricar un modelo de pseudoartrosis. En cirugía posterior se fijó con placa y tornillos. Se realizaron eutanasias a los 42 y 63 días para comparar los resultados de forma descriptiva mediante estudio histológico. No fue perdido ningún animal durante el experimento. En todas las muestras evaluadas se observó formación ósea en diferentes niveles de avance; defectos tratados con o sin el retiro del tejido involucrado en la pseudoartrosis presentaron una condición de reparación ósea comparables, determinando que la estabilidad de los segmentos óseos permite la reparación del tejido adyacente. El tejido cartilaginoso se presentó en algunas muestras asociadas a sectores con mayor presencia de formación ósea. La estabilización de la fractura es clave en la reparación ósea; la reparación se produce manteniendo o retirando el tejido presente en la pseudoartrosis.

ABSTRACT

OBJECTIVES: The aim of this study was to evaluate pulmonary function in patients with mandibular fractures and to determine the pattern of pulmonary functions in these patients.MATERIALS AND METHODS: This was a cross-sectional study of pulmonary functions in Nigerian non-smoking patients with isolated mandibular fractures managed at our health institution from December 2015 to June 2017. Forced vital capacity (FVC), forced expiratory volume in one second (FEV₁), peak expiratory flow rate (PEFR), and ratio of FEV₁ to FVC (FEV₁/FVC) were measured for all participants using a portable spirometer just before treatment. The pulmonary indices were compared with the predicted reference values for Nigerians to determine the respiratory pattern.RESULTS: Forty participants consisting of six females (15.0%) and thirty-four males (85.0%) with a female to male ratio of 1:5.7 were included in this study. The mean patient age was 34.5±13.1 years (range, 17–63 years). The mean FVC, FEV₁, FEV₁/FVC, and PEFR were 3.8±1.2 L, 3.0±1.0 L, 74.3%±13.8%, and 5.2±2.2 L/s, respectively. Comparison of data with predicted values revealed that 17 subjects (42.5%) had normal pulmonary function pattern while 23 subjects (57.5%) had features suggestive of obstructive and restrictive pulmonary function patterns.CONCLUSION: Isolated mandibular fractures presented with abnormal pulmonary function pattern.

ABSTRACT

BACKGROUND: The big data provided by Health Insurance Review and Assessment (HIRA) contains data from nearly all Korean populations enrolled in the National Health Insurance Service. We aimed to identify the incidence of facial fractures and its trends in Korea using this big data from HIRA.METHODS: We used the Korean Standard Classification of Disease and Cause of Death 6, 7 for diagnosis codes. A total of 582,318 patients were included in the final analysis. All statistical analyses were performed using SAS software and SPSS software.RESULTS: The incidence of facial fractures consistently declined, from 107,695 cases in 2011 to 87,306 cases in 2016. The incidence of facial fractures was the highest in June 2011 (n = 26,423) and lowest in January 2014 (n = 10,282). Nasal bone fractures were the most common, followed by orbit and frontal sinus fractures. The percentage of nasal bone fractures declined, whereas those of orbital fractures increased from 2011 to 2016 (P < 0.001). Among orbital fractures, inferior wall fractures were the most common, followed by medial wall fractures. Among mandibular fractures, angle fractures were the most common, followed by condylar process and symphysis fractures. Although it was difficult to predict the most common type of zygomatic and maxilla fractures, their incidence consistently declined since 2011.CONCLUSION: We observed trends in facial fractures in Korea using big data including information for nearly all nations in Korea. Therefore, it is possible to predict the incidence of facial fractures. This study is meaningful in that it is the first study that investigated the incidence of facial fractures by specific type.

ABSTRACT

The aim of this study was to evaluate the efficacy of CRB modification of retromandibular approach to gain surgical access for open reduction and internal fixation of mandibular sub-condylar fractures. A total number of 264 sustained extra-capsular subcondylar fractures from 230 patients were selected for the study over the period of 5 years. Evaluation of intraoperative accessibility, postoperative facial nerve function, postoperative complications and scar was ca-rried out. All the patients were treated using CRB Curvilinear approach. Patient follow up was re-corded for 1 year on a regular interval basis. Symptoms of postoperative facial nerve injury were seen in 2 patients which recovered with time, postoperative complications were not encountered in any case and minimum scar mark hidden in the cervical skin crease. Hence open reduction and internal fixation for Subcondylar fracture of mandible by using the CRB modification of re-tromandibular approach is a good alternative for other conventional approaches in having ease of access, ease of fixation, reduced incidences of injury to facial nerve and its branches with good aesthetic outcome

ABSTRACT

Introdução: Apesar de ser considerado um assunto controverso, o tratamento de fraturas mandibulares, que envolvem terceiros molares inclusos, já se afigura como uma temática amplamente debatida na literatura. Por outro lado, poucos estudos discutem o manejo das fraturas em região de dentes inclusos anteriores8 . Nesse sentido, o presente estudo visa relatar um caso de fratura associada a um canino transmigrado em parassínfise mandibular. Relato de caso: Paciente A.S.S., sexo masculino, 43 anos e 6 meses de idade, apresentou-se à emergência do Hospital Geral do Estado da Bahia, com histórico de acidente motociclístico cursando com trauma em face. O exame de imagem constatou fratura em parassínfise mandibular bilateral, associada ao deslocamento de canino previamente impactado. Optou-se pela remoção do dente envolvido, redução e fixação óssea com miniplacas e Barra de Erich. O acompanhamento pósoperatório revelou estabilidade da mandíbula e regressão dos sinais e sintomas pré-traumáticos. Considerações finais: Ao tratar fraturas mandibulares que envolvem dentes inclusos, deve-se ponderar acerca da remoção ou manutenção desse dente. Para tanto, o cirurgião deve avaliar o grau de comprometimento da unidade dentária bem como sua importância para redução e fixação ósseas... (AU)


Introduction: Despite being a controversial subject, the treatment of mandibular fractures involving the included third molars is already a widely debated topic in the literature. On the other hand, few studies discuss the management of fractures in the region of anterior included teeth8. In this sense, the present study aims to report a case of fracture associated with a transmigrated canine in the mandibular parasphysis. Case report: Patient A.S.S., male, 46 years and 6 months old, presented to the emergency of the State General Hospital of Bahia, with a history of motorcycle accidents, coursing facial trauma. The image examination revealed bilateral mandibular parashymphisis fracture, associated with the displacement of a previously impacted canine. It was decided for removal of the involved tooth, reduction and bone fixation with miniplates and Erich Bar. Postoperative follow-up revealed jaw stability and regression of post-traumatic signs and symptoms. Final considarations: When treating mandibular fractures involving included teeth, consideration should be given to the removal or maintenance of this tooth. Therefore, the surgeon should assess the degree of impairment of the dental unit as well as its importance for bone reduction and fixation... (AU)

ABSTRACT

Introdução: A preservação do nervo facial (NF) é uma das principais preocupações do cirurgião durante o tratamento aberto das fraturas mandibulares, uma vez que uma lesão nessa estrutura anatômica pode causar sequelas estéticas e funcionais permanentes. A existência de variações anatômicas (anastomoses e ramificações incomuns) aumenta o risco de danos no NF, mesmo nas mãos de cirurgiões experientes. O neuromonitoramento intraoperatório tem-se mostrado um grande aliado para evitar lesões nos ramos nervosos que podem estar envolvidos na área cirúrgica. Considerando a escassez desse assunto na literatura referente à cirurgia maxilo-facial, objetivamos demonstrar o uso da técnica de neuromonitoração do NF durante o acesso submandibular para o tratamento da fratura bilateral do ângulo mandibular. Relato de caso: No presente relato de caso, as abordagens cirúrgicas de ambos os lados não apresentaram danos permanentes ao NF. Esse resultado assim como a literatura sugerem que o neuromonitoramento intraoperatório proporciona maior segurança durante a realização de abordagens cirúrgicas, nas quais os ramos do nervo facial estão envolvidos, reduzindo, assim, o risco de sequelas nervosas. Considerações Finais: Esse recurso pode ser de grande auxílio no treinamento hospitalar ao longo do processo de formação de cirurgiões bucomaxilofaciais... (AU)


Introduction: Facial nerve (FN) preservation is one of the surgeon's major concerns during the open treatment of mandibular fractures since an injury to this anatomical structure can cause permanent aesthetic and functional sequelae. The existence of anatomical variations (anastomosis and unusual branching) increases the risk of FN damage even in the hands of experienced surgeons. Intraoperative neuromonitoring has proven to be a great ally to avoid injury to the nerve branches that may be involved in the surgical area. Considering the scarcity of this subject in the maxillofacial surgery literature, we aimed to demonstrate the use of the FN neuromonitoring technique during the submandibular approach for the treatment of bilateral mandibular angle fracture. Case report: In the present case report, the surgical approaches of both sides presented no permanent damage to the FN. Results: This result, as well as previous literature, suggests that intraoperative neuromonitoring provides greater safety during the performance of surgical approaches in which the facial nerve branches are involved and thus, reduces the risk of nerve sequelae. Final considerations: This resource can be of special assistance in teaching hospitals throughout the training process of maxillofacial surgeons... (AU)
