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.

Epidemiological Profile and Characterization of Oral and Maxillofacial injuries in Women Victims of Interpersonal Violence / Perfil Epidemiológico y Caracterización de las Lesiones Orales y Maxilofaciales en Mujeres Víctimas de Violencia Interpersonal

The objective of this study was to determine the epidemiological profile of women victims of violence and characterize the injuries affecting their maxillofacial region. This was an analytic study using secondary data from 470 expert reports of domestic violence involving women, collected from January 2007 to December 2011 in the Department of Dentistry of the Institute of Legal Medicine in the city of Feira de Santana, Bahia, Brazil. The majority of the examined women were Afro-caucasian (72.6 %), single (74.9%), and with mean age of 30.4 years. The buccal (51 %) and orbital (8.8 %) regions were the most affected extraoral sites. As to the oral cavity, the most affected sites were teeth (50.8 %) and the lip mucosa (35 %). In most cases the lesions against women were associated with an aggressor having a close relationship with the victim. The most prevalent lesions were edema; fracture; tooth dislocation; and bruise. These findings can subsidize the development of policies to prevent violence against women, and for public safety.

El objetivo fue determinar el perfil epidemiológico de mujeres víctimas de violencia y las lesiones que les acometieron la región oral y maxilofacial. Se trata de un estudio sobre datos secundarios realizado a partir del análisis de 470 informes periciales de violencia doméstica contra mujeres, recopilados entre enero del 2007 a diciembre del 2011, en el área de Odontología del Instituto Médico Legal de Feira de Santana (Bahía/Brasil). La mayoría de las mujeres estudiadas eran afrocaucásicas (72,6 %), solteras (74,9 %), con un promedio de edad de 30,4 años. En relación a la localización extraoral, las regiones bucal (51 %) y orbital (8,8 %) fueron las más afectadas. Los dientes (50,8 %) y la mucosa labial (35 %) fueron las estructuras intraorales más afectadas. En la mayoría de los casos, las lesiones estaban asociadas a un agresor con una relación cercana a las mujeres. Las lesiones más prevalentes fueron edemas, fracturas, luxación dental y equimosis. Estas hallazgos pueden colaborar en el desarrollo de acciones para combatir la violencia contra la mujer y para la seguridad pública.

Fratura de côndilos occipitais / Occipital condyles fractures

A fratura de côndilos occipitais é uma afecção considerada rara, mas que pode estar sendo subdiagnosticada. Fatores como a apresentação clínica variável, o exame físico frustro e a não identificação por radiografia simples dificultam esse diagnóstico, podendo levar a complicações como paralisia de nervos cranianos caudais e até mesmo a óbito. O presente estudo tem como objetivo revisar a literatura pertinente às fraturas de côndilos occipitais, com enfoque nas considerações anatômicas da junção craniocervical e ressaltando aspectos fisiopatológicos, parâmetros clínicos e as controvérsiasquanto ao tratamento. O incremento das técnicas radiológicas e a maior disponibilidade e uso de tomografia computadorizada possibilitaram o aumento do número de casos descritos dessas fraturas nas últimas décadas. A apresentação clínica é inespecífica e a tomografia da junção craniocervical é o método diagnóstico de escolha. A ausência de diagnóstico é responsável por sequelas, como déficits neurológicos, e foram descritas taxas de mortalidade de até 16% em casos de fraturas bilaterais. Omecanismo de injúria exato não é bem conhecido, mas a maioria dos autores indica a hiperextensão do pescoço associada à força vertical sobre a junção craniocervical. O tratamento é controverso, por causa da inconsistência nos resultados obtidos com o tratamento conservador baseado na classificação de Anderson e Montesano, em comparação com o escasso número de doentes tratados cirurgicamente.

The occipital condyle fractures are rare lesions, but they may have been under-diagnosed. Factors such as variable clinical presentation, inconclusive physical examination and no identification in the simple radiography difficult the diagnosis and may lead to complications such as paralysis of cranial nerves and death. This study aims to review the literature about occipital condyle fractures, emphasizing the anatomical considerations of the craniovertebral junction, pathophysiological view, clinical presentationand controversies regarding treatment. The improvement in radiological techniques and the increased availability and usage of computed tomography allowed the growth of reported cases of these fracturesin recent decades. The clinical presentation is nonspecific and CT of the craniocervical junction is the diagnostic method of choice. The absence of a diagnosis is responsible for sequel, such as neurologic deficits, and as mortality rates are of up to 16% in cases of bilateral fractures. The exact mechanism of injury is not well known, but most authors indicate the hyperextension of the neck associated with the vertical force on the craniocervical junction. The treatment is controversial due to the inconsistencies in the results obtained with conservative treatment based on the classification of Anderson and Montesano, compared to the small number of patients treated surgically.

Comportamiento de las fracturas maxilofaciales atendidas en el Hospital Universitario de Maabar, República de Yemen / Behavior of the maxillofacial fractures in the Maabar's University Hospital, Yemen Republic

Introducción: las fracturas maxilofaciales constituyen más del 50 porciento del total de fracturas, y en muchas ocasiones están asociadas a otras fracturas del cuerpo humano. Objetivos: estudiar el comportamiento de estas lesiones en el Hospital Universitario de Maabar, de la Universidad de Thamar (Yemen), determinar su relación con la edad, sexo, etiología y localización, y compararlo con los resultados de otros estudios realizados en Cuba y en otros países. Métodos: se realizó un estudio estadístico descriptivo retrospectivo de las fracturas maxilofaciales atendidas por la brigada de profesores cubanos en este hospital entre los años 2006 y 2009. Las variables estudiadas fueron: sexo, edad, causa de la fractura y región afectada, así como el tipo de fractura y los traumatismos asociados. Resultados: el sexo masculino fue mucho más afectado que el femenino. Los accidentes del tránsito fueron la causa más común (más del 50 por ciento de los casos). La fractura nasal fue la más frecuente, y en más de 150 casos se detectaron traumatismos asociados, muchos muy graves, como fracturas de cráneo, de miembros y heridas de partes blandas. Conclusiones: se confirman los resultados que el sexo masculino es el más afectado, y que los accidentes del tránsito son la principal causa de fracturas en la cara. La fractura nasal es la más frecuente de todas las de los huesos faciales (más del 50 por ciento de los casos), pero otros registran la mandíbula o la región zigomática como la zona más frecuente. Impresionaron las fracturas mandibulares en niños, lo cual no es frecuente en Cuba(AU)

Introduction: the maxillofacial fractures account for more than the 50 percent of the total of fractures and often are associated with other fractures of the human body. Objectives: to study the behavior of these lesions in patients from the Maabar's University Hospital of the Thamar's University (Yemen), to determine its relation to age, sex, etiology and location and to compare it with the results of other studies conducted in Cuba and other countries. Methods: a retrospective, descriptive and statistic study was conducted on the maxillofacial fractures seen by the Cuban professor brigade in this hospital between 2006 and 2009. The study variables were: sex, age, cause of the fracture and involved region, as well as the type of fracture and associated traumata. Results: the male sex was more involved that the female one. The road accidents were the commonest cause (more than the 50 percent of cases). The nose fracture was the more frequent and in more than of 150 cases there were associated traumata much of them very severe including skull fracture, of extremities and soft tissue wounds. Conclusions: the results confirm that the male sex is the more involved one and that the road accidents are the leading cause of face fractures. The nose fracture is the more frequent of all that of facial bones (more than 50 percent of cases), but others register the mandible or the zygomatic region as the more frequent involved zone. The mandibular fractures were impressive in children, something not frequent in Cuba(AU)

Retrospective study of prevalence of face fractures in southern Brazil.

Context: Trauma has been an important public health problem worldwide. Facial injuries are among the most common types of trauma treated at emergency departments, associated or not with injuries in other anatomic sites. The patterns of facial fractures are usually affected by geography and socioeconomic conditions. Aim: To investigate the prevalence of facial fractures in Lages, state of Santa Catarina, southern Brazil, from September 2003 to August 2008. Settings and Design: Cross-sectional, retrospective, epidemiological study. Materials and Methods: Data on patients' gender, age, etiological agent, and facial region affected by fracture were collected from the charts of patients treated with facial fractures. Statistical Analysis Used: Qualitative variables were expressed as absolute and relative frequencies, and quantitative variables as means and standard deviation. The Chi-square test was used to evaluate the association between gender, traffic accidents and facial region affected. The association between etiological agents and facial region affected was assessed using the chi-square test and the adjusted residuals analysis. Results: 492 patients presented with oral and maxillofacial trauma, with 988 facial fractures; 80.9% of the patients were men, and the most frequent age group was 21-30 years (29.5%). The most frequent causes of fractures were: Traffic accidents in 27.9%, physical assault in 14.9%, and bicycle falls in 10.5%; several other causes scored below 10%. Conclusion: Regular publication of epidemiological data is extremely important for the implementation of prevention campaigns and for an increased awareness of the etiology of fractures affecting the face and other anatomic sites.

Original research paper patterns of head injuries in fatal road traffic accidents in a rural district of Maharashtra- autopsy based study.

Road traffic accidents are the major causes of death worldwide. Head injury is the single most common cause of mortality in road traffic accidents; head being the most vulnerable part of the body. The present study was undertaken on 138 victims of road traffic accidents, died due to head injury to find out the patterns of head injuries, their age and sex distribution and site distribution of different types of fractures. The highest incidence was seen in age group of 21-30 years and males clearly outnumbered females. In the present study, most of the incidents occurred between 1200 to 1800 hours. The maximum number of victims (39.57%) died while on the way to hospital. The motor-cyclists were the commonest group of victims and trucks being the commonest offending vehicles. Intracranial haemorrhages were seen in 113 cases, skull fractures were found in 95 cases and injury to brain in 51 cases. Linear fracture of skull with basal fracture was the commonest type and temporo-parietal region was involved predominantly. Subdural haemorrhage was the commonest haemorrhage observed.

Risk factors for maxillofacial injuries in a Brazilian emergency hospital sample

BACKGROUND: Maxillofacial injuries occur in a significant number of trauma patients. Epidemiological assessments are essential to reaffirm patterns, identify new trends and develop clinical and research priorities for effective treatment and prevention of these injuries. OBJECTIVE: The aim of this study was to identify the epidemiological profile and risk factors associated with maxillofacial trauma treated at a referral emergency hospital for the Public Health System in the State Capital of Goiás, Brazil. MATERIAL AND METHODS: A cross-sectional study was designed including 530 patients with maxillofacial trauma, 76 percent male, with a mean age of 25.5±15.0 years. Data were collected between May 2003 and August 2004 over weekly shift-working periods. RESULTS: The main causes of trauma were traffic accidents (45.7 percent) and physical assaults (24.3 percent), and differences in etiological factors were identified according to gender (p<0.001). The distribution of patients according to age and etiology showed significant differences for traffic accidents (p<0.01), physical assaults (p<0.001), falls (p<0.001) and sport injuries (p<0.01). In the multinomial logistic regression analysis (R² = 0.233; p<0.05), age was associated with injury in traffic accidents and falls (p<0.01), sports-related accidents were associated with males (p<0.05), and alcohol consumption with assaults and traffic accidents (p<0.001). Facial soft tissue lesions were found in 98 percent of patients and facial fractures in 51 percent. CONCLUSIONS: The significant association of maxillofacial trauma with young males and alcohol consumption reinforces the need for educational strategies and the development of policies for the prevention and reduction of associated damage in this specific risk group.

Objetivo: Realizar levantamento epidemiológico das internações decorrentes das fraturas do crânio e dos ossos da face, avaliando os gastos do Sistema Único de Saúde com as internações na região Nordeste por um de período de dez anos. Métodos: Estudo de série temporal com dados do Sistema de Informações Hospitalares. Foram selecionadas as internações cujo diagnóstico fazia parte do capitulo XIX da Classificação Internacional das Doenças e a sua distribuição segundo: sexo, faixa etária, Unidade Federativa, valor médio, permanência média e ano de internação. Resultados: Foram encontrados 67.086 registros de internações por essas fraturas. A incidência média das fraturas de crânio e dos ossos faciais foi de 13,66 por 100.000 habitantes. A maioria das internações ocorreu no sexo masculino, em 82,5%, e nas faixas etárias de 20 a 29 anos de idade. As Unidades Federativas que apresentaram elevados coeficientes foram Rio Grande do Norte, Paraíba e Sergipe. No período foram gastos R$ 39.058.339,80 com internação e o valor médio por internação aumentou até 2003. Conclusões: As incidências de fraturas dos ossos do crânio e da face cresceram no período avaliado nos estados do Nordeste, sendo mais frequente no sexo masculino e nas faixas etárias de 20 a 29 anos. Consequentemente, os gastos públicos com internações por causa de fraturas dos ossos do crânio e da face cresceram no decorrer dos anos (AU)

Introduction: The increase of accidents and violence in Brazil has affected the organization of health systems, whose expenditures have been increasing due to their responsibility for attending to injuries. Aim: To perform an epidemiological survey of hospital admissions due to skull fractures and maxillofacial injuries, evaluating the expenses of the Single Health System with hospitalizations in northeast Brazil for 10 years. Methods: Temporal series study with data from the Hospital Information System. The cases selected were those diagnosed as part of the XIX Chapter of the International Classification of Diseases (ICD) and their distribution according to sex, age group, state, mean value, mean stay, and year of admission. Results: There were 67.086 records of admissions due to these fractures. The mean incidence of skull fractures and maxillofacial injuries was 13.66 per 100.000 people. Most of the admissions occurred among males (82.5%) in their twenties. The states with the highest indexes were Rio Grande do Norte, Paraíba, and Sergipe. In this period, R$ 39.058.339,80 were spent with hospitalizations, and the mean value per hospitalization increased until 2003. Conclusions: The incidence of skull fractures and maxillofacial injuries increased in the studied period in the northeast states, being more frequent among males in the 20-29 age group. Consequently, the public expenses with hospitalizations due to skull and maxillofacial injuries have increased over the years (AU)

Understanding temporal bone fractures

The temporal bone is the most complex bone in the human body and a tremendous force is required to fracture the temporal bone. Temporal bone fractures secondary to blunt trauma typically occur along structurally weakened points and can injure many vital structures, including the cochlear and vestibular end organs and the facial nerve, carotid artery, and jugular vein either alone or in combination. With the advent of advanced imaging techniques there has been better understanding of the temporal bone fractures. One should remember that temporal bone fractures are one of the serious conditions after head injury and can be associated with devastating complication if not identified and managed properly

Gastos do Sistema Único de Saúde com internações por causas externas em São José dos Campos, São Paulo, Brasil / Unified National Health System costs in São José dos Campos, São Paulo State, Brazil, for hospital admissions due to external causes

O objetivo do estudo foi mensurar os gastos diretos do Sistema Único de Saúde (SUS) com internações por causas externas em São José dos Campos, São Paulo, Brasil. Foram estudadas as internações por lesões decorrentes de causas externas, respectivamente capítulos XIX e XX da CID-10, no primeiro semestre de 2003, no Hospital Municipal Dr. José de Carvalho Florence. Foram analisados os valores pagos através do SUS, após a verificação da qualidade dos dados nos prontuários de 976 internações. Os maiores gastos totais foram por internações decorrentes de acidentes de transporte e quedas. O maior gasto médio de internação foi por acidentes de transporte (R$ 614,63), seguido das agressões (R$ 594,90). As lesões que representaram maior gasto médio foram as fraturas de pescoço (R$ 1.191,42) e traumatismo intracraniano (R$ 1.000,44). As internações com maior custo-dia foram fraturas do crânio e dos ossos da face (R$ 166,72) e traumatismo intra-abdominal (R$ 148,26). Os resultados encontrados demonstraram que os acidentes de transporte, as quedas e as agressões são importantes fontes de gastos com internações por causas externas no município.

The objective of this study was to identify direct expenditures for hospitalizations due to external causes in the Unified National Health System (SUS) in the city of São José dos Campos, São Paulo State, Brazil. Admissions to the Dr. José de Carvalho Florence Municipal Hospital resulting from external causes or injuries - ICD-10, chapters XIX and XX respectively - were analyzed for the first semester of 2003. 976 patient admission forms were analyzed, after data evaluation. Admissions with the highest total cost were those resulting from motor vehicle accidents and falls. The highest mean cost for hospitalization for injury was due to motor vehicle accidents (BRL 614.63), followed by assault (BRL 594.90). The highest mean cost for hospitalization due to injury was for cervical fractures (BRL 1,191.42) and head injuries (BRL 1,000.44). Hospitalizations with the highest daily cost were skull and facial fractures (BRL 166.72) and abdominal trauma (BRL 148.26). The study confirmed that motor vehicle accidents, falls, and assault are an important source of costs due to hospitalization for injuries.

Maxillofacial intervention in trauma patients aged 60 years and older.

The purpose of this study was to evaluate the incidence of trauma victims of age 60 years and older who required maxillofacial intervention. The study analyses the pattern of injuries and the various factors that predict the treatment plan of these patients. A retrospective study was carried out in 1820 trauma patients who reported to the Sri. Ramachandra Dental College and Hospital and required maxillofacial intervention, over a period of 5 years (October 2000 and September 2005). Of the total trauma victims, 185 patients were found to be aged 60 years more. In the majority of the patients, the injury was due to road traffic accidents (79.4%). Males (72.4%) sustained more injuries than females (27.6%). Soft tissue injuries were seen in 49.1% of the patients, while 14% had mandibular fractures. People in their early 60s were injured more often than their older counterparts. The findings of this study highlight the present situation with regard to maxillofacial trauma in patients aged 60 years and older and its management in this part of the country.

is high incidence of skull fracture associated with extradural hematoma in patients with head injury

To determine the correlation of skull fracture with extradural hematoma in head injury patients presenting to a tertiary care hospital in Pakistan. This descriptive study was carried out at Shifa International Hospital, Islamabad from January 2002 to January 2007. All patients who were operated for extradural hematoma during the study period were included in the study. Standard skull X-rays were done and type and location of fractures were noted on X-rays, CT scan and per-operatively. The incidence of skull fracture associated with extradural hematoma in various age groups was noted. The results were analyzed using SPSS version 14.0. A total of 110 patients underwent surgery for extradural hematoma. A linear fracture was demonstrated in 60 patients and a depressed skull fracture in 15 patients. Another 8 patients who did not have radiologically visible fracture were found to have a fracture line per-operatively. Thus, a total of 83 [75%] patients had skull fracture. There was no statistically significant difference in the incidence of skull fracture in various age groups. There is a strong association of skull fracture to extradural hematoma, however, a normal X-ray does not exclude extradural hematoma

Seating position, seat belt wearing, and the consequences in facial fractures in car occupants

INTRODUCTION: Trauma caused by traffic accidents is among the main etiologies involved in the occurrence of facial fractures throughout the world. However, the trauma mechanisms involved are different according to the location where the study was performed, due to different conditions of development, legislation, and culture. A retrospective study was done between February 2001 and July 2006, with the purpose of determining the epidemiology and the mechanisms involved in the occurrence of facial fractures among car occupants in the metropolitan area of São Paulo. METHODS: Data were collected from 297 patients admitted with facial fractures to the emergency room of the Hospital das Clínicas, São Paulo University Medical School. Within this period, 151 individuals had been involved in traffic accidents, among which 56 (37.08 percent) were inside passenger cars. These were grouped based on the seating position that they were occupying at the time of the accident and the wearing of seat belts. Data concerning the number and location of fracture lines were obtained from the different groups, and a fracture/patient index (F/P I) was calculated to compare and make reference to the impact energy among these groups, for subsequent analysis and discussion. RESULTS: 323 fracture lines occurred among 56 patients who were car occupants. By applying the F/P I, we obtained higher values in the group of rear-seat passengers who were not wearing seat belts (7.23 fractures per patient), followed by the group of drivers not wearing seat belts (6.33 fractures per patient), the group of front-seat passengers not wearing seat belts (5.58 fractures per patient), the group of drivers wearing seat belts (5.54 fractures per patient) and, finally, the group of front-seat passengers wearing seat belts (4.00 fractures per patient). None of the rear-seat passengers was wearing seat belts. CONCLUSION: The data collected indicate that the driver position shows a high...

INTRODUÇÃO: Os traumatismos devidos a acidentes de trânsito estão entre as principais etiologias na ocorrência de fraturas de face em todo o mundo. No entanto os mecanismos de trauma são diferentes, conforme o local onde o estudo foi realizado, devido a condições de desenvolvimento, legislação e cultura 1, 2, 3, 4. Com o objetivo de se conhecer a epidemiologia e os mecanismos envolvidos na ocorrência de fraturas de face em ocupantes de automóveis na região metropolitana de São Paulo, foi realizado um estudo retrospectivo entre Fevereiro de 2001 e Julho de 2006. MÉTODO: Foram coletados dados de 297 pacientes admitidos com fraturas de face na sala de emergência do HC-FMUSP. Destes, 151 indivíduos estiveram envolvidos em acidentes de trânsito sendo que 56 (37,08 por cento) estavam dentro de automóveis. Estes últimos foram agrupados baseados na posição em que estavam sentados no veículo no momento do acidente e no uso de cintos de segurança. Dados referentes ao número e localização dos traços de fratura foram obtidos nos diferentes grupos e um índice Fraturas/Paciente (IF/P) foi idealizado para comparar e avaliar o impacto nesses grupos, e para posteriormente serem analisados e discutidos. RESULTADO: Ocorreram 323 traços de fraturas nos 56 pacientes ocupantes de carros. Aplicando-se o IF/P obtivemos maiores valores no grupo de passageiros do banco traseiro sem cinto de segurança (7,23 fraturas/ paciente), seguido pelo grupo de motoristas sem cinto de segurança (6,33 fraturas/ paciente), passageiros dianteiros sem cinto de segurança (5,58 fraturas/ paciente), motoristas com cinto de segurança (5,54 fraturas/ paciente) e por último o grupo de passageiros dianteiros com cinto de segurança (4,00 fraturas/ paciente). Nesta amostragem, não houve ocupante do banco traseiro com cinto de segurança. CONCLUSÃO: Baseado nos dados dos pacientes e nos resultados do índice foi realizada uma análise comparando-se a incidência de fraturas de face em diferentes...

Etiologia e incidência das fraturas faciais em adultos e crianças: experiência em 513 casos / Etiology and incidence facial fractures in children and adults

O trauma facial apresenta incidência crescente nas últimas quatro décadas, principalmente devido ao aumento dos acidentes automobilísticos e da violência urbana, que continuam sendo as principais causas desses traumatismos em indivíduos jovens. OBJETIVO: Estudar as características da população vítima de trauma facial através das variáveis sexo, idade, profissão, tipo de fratura e suas causas. FORMA DE ESTUDO: clínico retrospectivo com coorte transversal. MAETERIAL E MÉTODO: Estudo retrospectivo por consulta a prontuários de 513 pacientes vítimas de trauma facial. RESULTADOS: Houve maior incidência de trauma de face em homens (84,9 por cento), brancos (82,7 por cento) e com idade média de 29 anos. Quanto à profissão, estudantes (16,6 por cento) e pedreiros (11,2 por cento) foram os mais acometidos. A mandíbula foi o local mais afetado (35 por cento), seguido do zigoma (24 por cento) e do nariz (23 por cento), sendo que a maioria dos pacientes tinha fratura única de face (81,5 por cento). Dentre as causas, destacaram-se os acidentes automobilísticos (28,3 por cento), agressões (21 por cento) e as quedas acidentais (19,5 por cento). CONCLUSÕES: Os acidentes automobilísticos continuam sendo a principal causa de trauma de face, principalmente de fraturas múltiplas devido à grande transmissão de energia cinética.

Epidemiology of mandibular fractures treated in a Brazilian level I Trauma Public Hospital in the city of São Paulo, Brazil

This article reviews cases of mandibular fractures treated at the Service of Oral and Maxillofacial Surgery of the Hospital Complex of Mandaqui (SUS/SP), which is a reference hospital complex for trauma in the northern area of the city of São Paulo, Brazil. Ninety-eight patients with mandibular fractures were seen at the hospital between January and December, 2001. Out of this total, 91 cases whose files were deemed adequate in terms of data accuracy and completeness were reviewed. The following data were collected for the study: age, gender, etiology, anatomical fracture site, treatment modality, relation to other facial bone fractures, hospitalization time and posttrauma complications. Motorcycle accident was the major cause of mandibular fractures followed by physical aggression and height fall. The mandibular anatomical sites of higher fracture incidence were: body, symphysis and condyle. The most commonly performed treatment modes were conservative approach or open reduction and intraosseous fixation. In conclusion, motorcycle accidents were associated with a larger number of facial fractures and most predominantly affect 21-30 year-old males. On the average, motor vehicle accident victims had more (and more severe) fractures than physical aggression victims. Complications were mostly associated with angle fractures and hospitalization period. Polytraumatized patients presented greater morbidity for complications.

O artigo tem como objetivo revisar casos de fraturas de mandíbula atendidos no Serviço de Cirurgia Bucomaxilofacial do Conjunto Hospitalar do Mandaqui (SUS/SP), hospital de referência para trauma na região norte de cidade de São Paulo. De janeiro a dezembro de 2001, foram atendidos 98 pacientes com fraturas de mandíbula no hospital. Dentre estes, 91 casos que dispunham de dados suficientes em prontuários foram analisados. Para o estudo foram considerados: idade, gênero, etiologia, local anatômico da fratura, modalidade de tratamento, relação com fraturas de outros ossos faciais, tempo de hospitalização e complicações. Acidente motociclístico foi a principal causa de fraturas mandibulares, seguido de agressão e queda de altura. Os três locais anatômicos de maior incidência foram: corpo, sínfise e côndilo. O modo de tratamento consistiu de abordagem conservadora ou redução aberta e fixação interna. Conclui-se que acidentes motociclísticos estão associados a um maior número de fraturas mandibulares com predominância em homens de 21 a 30 anos. Vítimas de acidentes com veículos apresentaram, em média, mais fraturas do que vítimas de agressões. As complicações mostraram-se associadas ao maior período de hospitalização e fraturas de ângulo mandibular, e tiveram maior incidência em pacientes politraumatizados.

Prevalent age group, cause and site of pediatric facial bone trauma at two tertiary units in Pakistan

The pediatric oro-facial trauma is observed in Indian Subcontinent as well as in developing countries. The school group and teenage group children are frequently involved. Dento-alveolar fractures are common comparative to mandibular fractures whereas middle third of the face is exceedingly rare. The mandible is fractured at variety of sites in pediatric facial trauma. The condylar cartilage, developing permanent teeth and advancing growth, all result in injury at different sites of the mandible and hence the various treatment modalities are required to manage these fractures. In majority, the causes of fractures are accidental falls and road traffic accident [RTA]. 141 patients presented at Oral and Maxillofacial Surgery Department of Punjab Dental and Children Complex Hospitals, Lahore from September 2003 to December 2005. The age of the patients ranged from infancy to early teenage [>0 years to 15 years] with facial bone injuries. The children were divided into four groups; Group "A " [Infants], Group "B" [Pre-school], Group "C" [School] and Group "D" [Teenage]. After initial examination, different radiographs [orthopantomograph, posterioanterior mandible and occipitomentalis views] were utilized to confirm the site and diagnosis. Different treatment modalities depending upon the site, bone involved and age group of the patients were used to manage the fractures. Few patients were managed conservatively. The dento-alveolar trauma was noticed frequently in group "C" and "D" and it is 50.35% of the total facial bone trauma. The cause of the trauma in majority of the patients was by accidental falls. 40 patients were of maxillary dento-alveolar trauma and nine were of mandible. Twenty-two children had bi-maxillary dento-alveolar trauma. It was observed that the maxillary trauma was common in skeletal /dental class II div I cases. The next common bony trauma was of the mandible [45.39%]. 50% of total mandibular fractures were from group "C". The site of the fracture in these patien ts was the body of the mandible and frequently associated with mandibular condyles [29%] whereas 9.37% of them had unilateral condylar fractures. This group had the highest frequency of mandibular fractures among facial bone fractures. Group 'D' [20.31%] of total mandibular fractures had high male prevalence [80%]. Maxillary fractures were 2.83% of the total facial bone trauma. The patients had Le Fort I or high Le Fort I fractures while one patient [presented 15 days after trauma] had Le Fort III fracture. The Le Fort III patient had fall from double story building and had head injury too. Two patients had trauma due to automobile RTA. All patients of maxillary fracture were from early age group "C" and there was no associated mandibular fracture in these patients. Zygomatic fractures were 1.41% of the total facial bone trauma. One patient had fracture from fall [stairs] and other had RTA. The patterns and sites of pediatric facial bone fracture vary within age groups. Majority of facial bone tr auma results in school going and early teenage groups with definite male predominance. Dento-alveolar and mandibular fractures are frequent with negligible mid face fractures. The pediatric facial bone fractures should be managed at their earliest to avoid complications

Child abuse: radiographic findings at King Chulalongkorn Memorial Hospital.

OBJECTIVE: To describe radiographic findings in physically abused children. MATERIAL AND METHOD: The physically abused children diagnosed in King Chulalongkorn Memorial Hospital from 1998 to 2002 were retrospectively reviewed of medical records and radiographic imaging. RESULT: Eighteen of 30 physically abused children had positive radiographic findings and 15 of 18 were related to head injury. Subdural hematomas and skull fractures were the two most common findings found in 11 cases and 9 cases respectively. Seven of 11 cases of head injury had retinal hemorrhage. Fractures other than the skull were detected in 6 patients, located at the long bones, ribs and spines. The abused children with positive radiographic findings were more commonly found in younger infants and mucocutaneous lesions might be absent. CONCLUSION: Inflicted head injury was the most common radiographic findings in the present series. Shaking-impact mechanism was likely to play a significant role in this group of patients.

Prevalencia de fracturas faciales vinculadas con el deporte / Prevalence of facial fractures linked to sports practice

Se realizó una investigación descriptiva y transversal en 57 pacientes con fracturas faciales adquiridas durante la actividad deportiva, los cuales fueron atendidos en el Servicio de Cirugía Maxilofacial del Hospital Provincial Saturnino Lora de Santiago de Cuba, en el quinquenio 1992-1996. Este tipo de lesión representó el 6,2(por ciento) del total de tratadas en dicho período. En los atletas que jugaban con pelota y practicaban técnicas de combate hubo la mayor prevalencia de estas lesiones, fundamentalmente en los deportes de pelota, boxeo, baloncesto, karate y softbol. El impacto contra otro atleta fue el mecanismo de lesión más frecuente, sobre todo en los grupos de combate y juegos con pelota. Las fracturas de mandíbula dentoalveolares y cigomáticas resultaron ser los patrones de fracturas preponderantes. La conducta terapéutica en estos pacientes no difirió sustancialmente de la aplicada en aquellos con lesiones producidas por otras causas. La restricción de la actividad atlética osciló entre 9 y 15 semanas después del tratamiento inicial. En los atletas de alto rendimiento lesionados se impone establecer las estandarizaciones en su proceso rehabilitador para la toma de decisiones con respecto a su incorporación, tanto a la práctica como a la competencia, lo cual es fundamental en este sentido(AU)

A descriptive cross-sectional research study was made on 57 patients with facial fractures suffered during sporting activities. These patients had been seen by the Maxillofacial Surgery Service of "Saturnino Lara" provincial hospital in Santiago de Cuba from 1992 to 1996 and this type of lesions represented 6.2 percent of the fractures treated in this period of time. These lesions were more prevailing in athletes who mainly played ball sports, boxing, basketball, karate and softball. The collision with another sportsman was the most frequent injure mechanism fundamentally fight and ball sports. Dentoalveolar and zygomatic mandibular fractures were the predominant fracture patterns. Therapeutical procedures applied to these patients did not differ significantly from that followed in other types of lesions. Sports practicing interruption ranged from 9 to 15 weeks after the initial treatment. Regarding high performance athletes that get injured, it is necessary to set standards for their rehabilitation process to help in taking decisions as to their re-incorporation to sports practice and competition(AU)
