A research report submitted to the Faculty of Health Sciences, University of the Witwatersrand, Johannesburg, in partial fulfilment of the requirements for the degree of Master of Science in Dentistry in the branch of Maxillofacial and Oral Surgery. Johannesburg, 2015 / Aim: The aim of this prospective study was to compare epidemiologic characteristics of maxillofacial fractures between Charlotte Maxeke Johannesburg Academic Hospital (CMJAH) and Polokwane–Mankweng Hospital Complex (PMHC). Objective: To compare the patterns; aetiologies and incidences of maxillofacial fractures in patients of all ages between the two units. Materials and Methods: We present a prospective study of 194 patients with 226 maxillofacial fractures reported and treated between CMJH and PMHC from December 2013 to August 2014. These patients were clinically and radiographically assessed by registrars and a consultant in both units. Variables recorded included Patient’s age; file number; sex; socioeconomic status; population group; aetiology; time of injury; identity ( whether known or unknown ) of assailant; the site of the fracture and associated injuries. Results: Of the 194 total patients from both units, 159(82.0%) patients were males and 35(18.0%) patients were females, giving overall male to female ratio of 4.54:1. The minimum age was (2) two years and the maximum age was 61 years. In both males and females, the majority (75%) of patients were in the age group of 20-39 years with a peak frequency in the 3rd decade. The overall mean age was 30.6 (10.02). Assaults were by far the leading cause of maxillofacial fractures from our study accounting for 60.3% fractures of the total study population, followed by road traffic accidents accounting for 17.5%. Road traffic accidents accounted for 22.7% maxillofacial fractures in PMHC, a rate higher than CMJAH (14.8%) and overall rate (17.5%). Sport injuries accounted for more (6.1%) maxillofacial fractures in PMHC than CMJH (0.8%). In total, 127(65.8%) patients sustained maxillofacial fractures during the night and 66(34.2%) patients during the day. The mandible was the most frequently fractured facial bone (73.0%), followed by the zygoma. The angle of the mandible was the most common fractured site (35.0%). Conclusion: Interpersonal violence is by far the leading cause of maxillofacial fractures in South Africa. Prevailing factors like socioeconomic status of patient; industrialisation and geographic location have somewhat influenced the characteristics of maxillofacial fractures in the two units.

No Brasil os idosos representam cerca de 9% da população, sendo aproximadamente 21 milhões de pessoas com mais de 60 anos. Este trabalho analisou características epidemiológicas de pacientes idosos vítimas de trauma de face atendido pela Área de Cirurgia Buco-Maxilo-Facial da Faculdade de Odontologia de Piracicaba (FOP) - Unicamp, na cidade de Piracicaba e região, no período de abril de 1999 a dezembro de 2012. A análise foi direcionada a dados relativos de variáveis populacionais como idade, gênero, cor, etiologia do trauma, lesões corporais na face ou não, incluindo fraturas de face ou não e fraturas associadas, tratamento instituído, tempo decorrido entre o trauma e o tratamento, além do período de proservação e complicações. Foram analisados dados dos pacientes, através de preenchimento de um formulário clínico especificamente elaborado para a anotação de dados relativos ao estudo de traumatismos faciais. Foram excluídos do trabalho pacientes com preenchimento incompleto das informações. Um total de 237 pacientes idosos foram avaliados, 127 (53,6%) pacientes do gênero masculino e 110 (46,4%) do gênero feminino, a queda foi a causa mais frequente com 146 casos (61,6%) do total, com maior incidência no terço médio de face com 114 fraturas (48,1%), sendo que os ossos próprios do nariz 47 casos (19,8%) e o osso zigomático 42 casos (17,7%), da mesma forma que em relação ao tratamento, dos 237 pacientes avaliados 101 casos (42,6%) foram tratados conservadoramente, 28 casos (11,8%) foram submetidos à cirurgia e em 18 casos (7,6%) não foi realizado nenhum tratamento. O presente estudo mostrou que a queda foi à causa com maior predominância, resultando em fraturas do terço médio com indicação cirúrgica cada vez menor neste grupo de população, exceto em casos onde a função esteja comprometida, tendo-se em conta as alterações fisiológicas, psicológicas decorrentes do envelhecimento. / Abstract: Recent studies demonstrated an increase in the elderly population. In Brazil the elderly represent about 9% of the population, approximately 21 million people over 60 years. This study examined the epidemiological characteristics of elderly victims of facial trauma attended by Area Surgery Maxillo-Facial, Piracicaba Dental School (FOP) - Unicamp, in Piracicaba city and region, from April 1999 to December 2012. The analysis was directed at population data for variables such as age, gender, race, trauma etiology, injury to the face or not, including facial fractures or not and associated fractures, treatment given, time elapsed between injury and treatment, beyond the period of follow up and complications. We analyzed data of patients by completing a form specifically designed for clinical annotation data for the study of facial trauma. Were excluded from the study patients with incomplete filling of the information. A total of 237 elderly patients were evaluated, 127 (53.6%) patients were male and 110 (46.4%) females, the fall was the most frequent cause in 146 cases (61.6%) of total with the highest incidence in the middle third of the face with 114 fractures (48.1%), sit the bones of the nose 47 cases (19.8%) and zygoma 42 cases (17.7%), and the total patients evaluated with respect to treatment of 237 patients evaluated, 101 cases (42.6%) were treated conservatively, 28 cases (11.8%) underwent surgery and 18 cases (7.6%) underwent treatment. This study showed that the fall was the most predominant cause, resulting in fractures of the middle third and decrease less surgical indications for this group, except in cases where the function is compromised, and sings in the physiological, psychological resulting from aging. / Doutorado / Cirurgia e Traumatologia Buco-Maxilo-Faciais / Doutor em Clínica Odontológica

Given the importance assumed by the TTA on these traumas, this study aims at evaluating the prevalence and factors associated with its occurrence on the victims of such violence. MATERIALS AND METHODS: Cross-sectional retrospective study performed at nucleus of forensic medicine and dentistry from January 2008 to December 2011. Data analysis was performed using the Statistical Package for Social Sciences including the frequency distribution and descriptive analysis of socioeconomic factors, injuries and TTA characteristics, and analytical analysis by using the chi-square test and Poisson logistic regression. RESULTS: A total of 2,570 medical and dental records were evaluated. The mean age of victims was 34.38 years (SD = 15.00 years), and the men to women ratio of 3.5:1. Most did not have a partner (56.5%) had up to 8 years of education (55.7%), was not employed (52.1%) and resided in the Metropolitan region (51.6). Regarding the information about the accident: motorcycle accidents were prevalent (67.8%) occurred during the day (55.8%) and on weekdays (62.9%). The facial injuries occurred in 421 victims (16.4%), being facial multiple trauma the most prevalent (44.3%), as well as the soft tissue injuries (57.5%). The body region most affected was the lower limb (37.6%) followed by associated trauma (28.9%). A statistically significant association was found between the type of trauma (facial/body) and age, residence, marital status, education, victim s occupation, type of accident, day of week and time of day. The final multivariate model of hierarchical Poisson regression was composed of four co-variables: housing, education, type of accident and time of day. CONCLUSION: The study showed factors associated with facial trauma, enabling the targeting of public health policies in order to prevent and reduce the prevalence of facial trauma resulted from terrestrial transport accidents, especially in those high-risk groups. / Os acidentes de transporte terrestre (ATT), são considerados um grave problema de saúde pública mundial, pois causam mortes, incapacidades e traumas, incluindo nesse segmento os traumas faciais. Tendo em vista à importância assumida pelos ATT nesses traumas, foi objetivo desse estudo avaliar a prevalência e os fatores associados ao trauma facial, nas vítimas deste tipo de violência. MATERIAIS E MÉTODOS: Estudo transversal censitário realizado m 2.570 laudos médico-odontológicos do período de Janeiro de 2008 a Dezembro de 2011 em núcleo de medicina e odontologia forense que referência para 23 cidades. A análise dos dados foi realizada utilizando o programa Statistical Package for Social Sciences e incluiu distribuição de frequência e análise descritiva para os fatores socioeconômicos, características do ATT e lesões faciais e corporais, e analítica mediante uso de teste qui-quadrado e regressão de Poisson. RESULTADOS: A média de idade das vítimas foi de 34,38 anos (DP = 15,00 anos). A proporção de homens para mulheres de 3,5:1. A maioria não possuía companheiro (56,5%), tinha até 8 anos de estudo (55,7%), não era assalariado (52,1%) e residia na região metropolitana (51,6). Em relação aos dados sobre o acidente: os acidentes motociclísticos tiveram maior prevalência (67,8%), ocorreram no período diurno (55,8%) e nos dias úteis (62,9%). As lesões faciais ocorreram em 421 vítimas (16,4%), sendo o politraumatismo facial o mais prevalente (44,3%), assim como os traumas de tecido mole (57,5%). A região do corpo mais atingida foram os membros superior e inferior - (37,6%) seguido de traumas associados (28,9%) e de cabeça (12,1%). Uma associação estatisticamente significativa foi encontrada entre a presença de trauma facial (presente/ausente) e a faixa etária, moradia, situação conjugal, escolaridade, trabalho da vítima, o tipo de acidente, dia da semana e período do dia. O modelo multivariado final da regressão hierárquica de Poisson foi composto de quatro co-variáveis: moradia, escolaridade, tipo de acidente e período do dia. Indivíduos que moram na região adjacente (RP=1,41, 95% IC: 1,02-1,96, p=0,038), nas cidades além dessa região (RP=1,50, 95% IC: 1,10-2,26, p=0,010), acidentes ocorridos no período noturno (RP=1,42, 95% IC: 1,10-1,84, p=0,007) e vítimas que tem até 9 anos de idade (RP=2,31, 95% IC: 1,03-5,17, p=0,041) têm maior prevalência de durante um acidente de terem trauma facial. Já as vítimas de acidente motociclístico têm menor prevalência de trauma facial do que os automobilísticos (RP=0,59, 95% IC: 0,44-0.89, p=0,001). CONCLUSÃO: O estudo evidenciou fatores associados ao trauma facial, possibilitando o direcionamento de políticas públicas de saúde, a fim de prevenir e diminuir a prevalência dos traumas faciais decorrentes de acidente de transporte terrestre, principalmente naqueles grupos de maior risco: vítimas de acidente automobilístico, moradores da região adjacente e além desta, com 9 anos de idade ou menos, e acidentes ocorridos no período noturno.
