Mandibular 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.
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.
Historical cohort.
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.
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.
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.
下颌骨骨折是第二常见的面部骨折，且在过去几年病例数量显著增加。识别错误和治疗不当可导致永久性美学或功能畸形。
评估1974年1月至2002年12月在乌贝兰迪亚联邦大学临床医院进行的下颌骨骨折复位病例。
历史性队列研究。
根据与患者、创伤、体征和症状以及手术治疗相关的因素，对293例下颌骨骨折复位病例进行回顾性分析。
多年来下颌骨骨折数量有明显增加趋势。男性患病率更高（4:1），发病高峰在20至29岁之间。本研究中骨折的主要原因是交通事故和暴力，占72.4%。135例患者仅发生一处骨折。受伤最多的部位依次为正中联合、髁突、角部、体部、升支和喙突。我们进行了闭合复位（28例）、切开复位（213例）以及两者联合（11例患者）；56.8%的患者在头3天内接受治疗；50.4%的患者在术后第一天出院。约10%的患者出现并发症，骨髓炎是最常见的并发症。
下颌骨骨折的发病率在男性中显著更高，发病年龄在第三个十年。最常见的原因是交通事故，正中联合和髁突是受伤最多的部位。超过半数的病例为孤立性骨折。大多数患者在头三天接受治疗，并在术后第一次就诊时出院。闭合复位是最常用的治疗方法。最常见的并发症是骨髓炎。
