下颌骨骨折的临床回顾性研究

A retrospective investigation about mandibular fractures

目的 探讨下颌骨骨折的发生特点。方法 对 376例下颌骨骨折患者的性别、年龄、致伤原因、骨折部位、治疗方法进行分析。结果 男性多于女性 ,2 0～ 39岁为高发年龄 ;交通事故为主要致伤原因 ;多发骨折多于单发骨折 ,好发部位为下颌体、颏部和髁状突 ,骨折移位者占 79% ;31%的伤员有颅面、颅脑和四肢合并伤 ;主要采用颌间牵引复位。结论 男性及青壮年为骨折高发人群 ,下颌体、颏部和髁状突为好发部位 ;交通事故是下颌骨骨折及重型复合伤的主要致伤因素 ;治疗以颌间牵引复位为主 。

WT5”BZ]Objective To analysis the causes, clinical characteristics and treatment of mandibular fractures. Methods A retrospective study was conducted in 376 cases with mandibular fractures for the sex, age,cause,anatomic site, complicated injury and treatment. Results Mandibular fractures occured mainly in the male(77%), and in 20~39 years old age(74%). Vehicle crashs were the leading cause of mandibular fracture. Fracture in mandibular body was more common than in other sites. 55% of cases had more than one site fractured, and average 1.72 sites for each patients. Near 1/3 cases had complicated trauma in cranioface, craniocerebrum and extermity. Most cases were treated with nonoperated therapy and total healing rate was 94%. Conclusion The most prevalent group of mandibular fracture was male and in age of 20~40. Majority of the fractures were caused by traffic accident. Intermaxillar fixation was effective for most patients, but operative reduction should be used in these cases who had multiple and serious displaced mandibular fractures. [WT5”HZ]
