Fratura de mandíbula: análise de 293 pacientes tratados no Hospital de Clínicas da Universidade Federal de Uberlândia

Abstract

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.

Epidemiological study of facial fractures at the Oral and Maxillofacial Surgery Service, Santa Casa de Misericordia Hospital Complex, Porto Alegre - RS - Brazil

“…Fractures of the zygomatic complex were responsible for 44.5% of the total fractures in this study, followed by mandible fractures, with 42.5%, both in agreement with the reviewed literature 5,20,[21][22][23]26,28,30,31,34 .…”

Prevalence of Maxillofacial Traumas in a Hospital of the Interior of Brazil

“…More stringent supervisions in favor of transit legislation as well as social education activities with an appeal to morbidities related to vehicles accidents can help to minimize the trauma caused by these mechanisms. The distribution of hospitalizations due to facial trauma according to the month of occurrence in the Santa Casa de Caridade de Diamantina hospital followed the same pattern of a study conducted in the city of Uberlândia, in Minas Gerais state, which evidenced the month of August as the month of highest incidence [17]. The year of 2014 was highlighted by the number of patients hospitalized for treatment of maxillofacial fractures in the Santa Casa de Caridade de Diamantina hospital, with a higher demand in the second semester.…”

“…Considering that the city of Diamantina is the center pole of the Jequitinhonha Expanded Health Region, being then reference for 24 cities, it is verified that it is fulfilling well its role in the regionalization of health. The percentage of treatment for multiple facial fractures was higher than the other procedures (54.7%), even than the single mandible fractures that are mentioned by some authors as the most prevalent [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. The treatment of simple facial fractures was reported by Montovani et al [6] in 72.3% of the cases in a study conducted in the interior of the state of São Paulo.…”

Perfil epidemiológico dos pacientes com fraturas dos ossos da face em um hospital público do estado de Sergipe

“…Estudos como os de Falcão et al (2005) Com relação aos ossos da face, a prevalência maior de ocorrência foi na mandíbula. Este achado é semelhante ao descrito por vários autores (ADEYEMO et al, 2005;CHRCANOVIC et al, 2004;FALCÃO et al, 2005;FERREIRA et al, 2005;PATROCÍNIO et al, 2005;CAUÁS, 2004;SAKAI et al, 2005;WULKAN;PARREIRA JUNIOR;BOTTER, 2005). Após a mandíbula, seguiramse em ordem decrescente as fraturas dos ossos: zigomático, maxila e nasal.…”
