“…The age range 20 to 29 years was the most affected one, a fact that coincides with data from mandible fractures 7,9 , but also from other facial bones 11,12 . The predominance of male gender in the age range 20-29 years is due to the fact that this group is more prone to traffic accidents and violence, normally associated with use of alcoholic beverage 6,7,10 .…”

Mandi bular fracture is the second most common facial fracture and there has been a significant increase in number of cases in the last years. Misidentification and inadequate treatment can take to permanent aesthetic or functional deformity. Aim: Evaluate cases of mandibular fracture reduction in the Hospital of Clinics of the Federal University of Uberlândia, from January of 1974 to December of 2002. Study design: historical cohort. Patient and Method: Two hundred and ninety-three cases of reduction of mandibular fractures were retrospectively analyzed according to factors related to: patient, trauma, signs and symptoms, and surgical treatment. Results: There has been a clear tendency of increase of the number of mandibular fractures along the years. There was higher prevalence in male (4:1), with occurrence peak between 20 to 29 years old. The principal causes of fracture in this study were traffic accidents and violence, representing 72.4%. One hundred and thirty-five patients presented only one fracture. The most injured sites were, in decreasing order, symphysis, condyle, angle, body, ramus, and coronoid. We performed closed reduction (28), open reduction (213) and association of the two (11 patients); 56.8% of the patients were treated within the first 3 days; and, 50.4% were discharged from the hospital until the first postoperative day. About 10% of the patients presented complications, being osteomyelitis the most frequent one. Conclusion: The incidence of mandibular fractures was remarkably larger in the male sex, during the third decade of life. The most common cause was traffic accident, and symphysis and condyle were the most injured sites. Isolated fractures occurred in over half of the cases. Most of the patients were treated in the first three days and were discharged until the first postoperative visit. Closed reduction was the treatment most commonly employed. The most frequent complication was osteomyelitis.

“…Many studies have shown that young adult males were commonly affected. 7,9,10,24,26 The role of road traffic accidents as a very common etiology for zygomatico-maxillary complex fractures has been well documented by several studies 6,15,24,[26][27][28] which is consistent with our study. Other etiologies in our study included accidental fall, interpersonal violence, occupational injury and sports injury.…”

“…6,9 Zygomatico-maxillary complex fractures most commonly occur in young adult males. 7,[9][10][11] The frequently encountered clinical features of the zygomaticomaxillary complex fractures include circumorbital edema, subconjunctival hemorrhage, flattening of the cheek, sensory disturbances, limitation of mandibular movements, enopthalmos and diploplia. 8,[12][13][14] Clinical diagnosis is confirmed with radiographs and CT scan.…”

Abstract:The aim of the study was to record the etiology, pattern and management of zygomatico-maxillary complex (ZMC) fractures seen in two centres in Mysore and to compare the findings with other studies in literature. A fifteen year retrospective study involving 123 patients with ZMC fractures were selected from a pool of 219 patients who sustained maxillofacial fractures during the period under study. The age distribution, gender distribution, etiology, associated injuries, associated maxillofacial fractures, clinical features, distribution of radiographic investigation, radiographic findings associated with ZMC Fractures, pattern of fractures and various modalities of management and surgery were recorded. In this study, 86.17% were males and 13.83% females. Most (39.02%) patients were aged 21-30 years. There was highly significant association between road traffic accidents and ZMC fractures. (Chi square value 291.512, P < 0.001). The most frequently associated maxillofacial fracture was nasal bone fracture (28.45%). Circumorbital edema was the commonest clinical feature (88.61%); Keene's approach was the commonest method of zygoma elevation (78%). Two point internal fixation was commonly used (46.83%). Among two point fixation, frontozygomatic suture and zygomatico-maxillary suture were commonly plated (64.86%). Among one point internal fixation, zygomatico-maxillary suture was most commonly plated (40.74%). This study has shown that road traffic accidents have been responsible for most of the ZMC fractures in our geographical area and two point fixation at zygomatico-maxillary suture and fronto-zygomatic suture has been the commonest method of fixation and Keene's approach has been the choicest method for elevation of zygoma.

“…Os dados relacionados ao sexo demonstram predominância masculina sobre a feminina num índi-ce de 4,3:1, o que é coincidente com a literatura 1,3,4,8,10 , sendo vítimas mais freqüentes de acidentes automobilísticos ou motociclísticos, e apresentam um envolvimento maior em agressões e quedas. A faixa etária de 20 a 29 anos foi a mais atingida, dado que coincide com relatos 3 não só de fraturas de mandíbula mas também com de outros ossos faciais 8 .…”

A mandíbula é o único osso móvel da face e participa de funções básicas como mastigação, fonação e deglutição, além de participar da manutenção da oclusão dentária ocupando juntamente com a maxila a maior porção óssea do esqueleto facial 1 .Devido a sua topografia, anatomia e projeção no terço inferior da face, é freqüentemente atingida por traumas podendo resultar em fraturas, principalmente em acidentes de trânsito, agressões, quedas ou acidentes esportivos 10 .As fraturas mandibulares podem levar à deformidades, sejam por deslocamentos ou perdas ósse-as não-restauradas, com alterações de oclusão dentária ou da articulação temporomandibular (ATM). Quando não identificadas ou tratadas adequadamente, estas lesões podem levar à seqüelas graves, tanto estéticas como funcionais 1,6,11 .Este estudo tem como objetivo avaliar 166 pacientes consecutivos com fraturas de mandíbula atendidos e tratados no setor de Trauma de Face da disciplina de Cirurgia Plástica da UNIFESP-EPM, distribuídos conforme o sexo, idade, etiologia, localização das fraturas, técnicas de tratamento e complicações pós-operatórias. PACIENTES E MÉTODOForam estudados 166 pacientes consecutivos, vítimas de trauma mandibular (em um total de 267 fraturas), atendidos e tratados na disciplina de Cirurgia Plástica da UNIFESP/EPM no período de janeiro de 1991 a março de 1996.Os pacientes foram analisados através do levantamento de prontuários, avaliação das radiografias do pré e pós-operatório e através das Fichas de Trauma, específicas do setor de Trauma de Face da Cirurgia Plástica da UNIFESP / EPM. Foram então agrupados segundo o sexo, faixa etária, lesões associadas, tratamento e complicações pós-operatórias. RESULTADOSDo total de pacientes, encontramos 135 homens (81,3%) e 31 mulheres (18,7%), em um índice masculino/feminino de 4,3:1 (gráfico 1).A faixa etária variou de 1 ano e 4 meses a 59 anos (média de 27,11). As idades foram agrupadas em décadas, e a faixa etária mais acometida foi dos 20 aos 29 anos (42,8%), e a menos dos 50 aos 59 (4,8%) (gráfico 2).A etiologia mais freqüente de fraturas de mandíbula neste estudo foi relacionada aos acidentes de trânsito (81 casos -48,8%), em que 41,6% envolviam veículos de transporte e 7,2% atropelamento; seguido das quedas (44 casos -26,5) e agressões (39 casos -23,5%). Somente dois pacientes sofreram acidentes esportivos (gráfico 3). As diferentes etimologias dos acidentes de trânsito e agressões encontram-se na tabela 1.Foram identificadas 267 fraturas nos 166 pacientes tratados (1,6 fraturas/paciente), sendo que 86 pacientes (51,8%) apresentavam fraturas úni-cas e 80 pacientes (48,2%) fraturas múltiplas, com média de 2,2 fraturas/paciente no último grupo.A região do corpo da mandíbula foi a mais atingida (76 fraturas -28,5%), seguida do côndilo (71 fraturas -26,6%), região sinfisária (53 fraturas -19,9%), ângulo (38 fraturas -14,2%), e alveolar isoladamente (5 fraturas -1,9%). A região menos atingida foi o processo coronóide (3 fraturas -1,1%) (figura 1).Correlacionamos as fraturas de mandíbula com outras le...
