80例下颌骨髁状突骨折临床患者分析

An epidemiological retrospective study of 80 condylar fractures

目的探讨下颌骨髁状突骨折的发生特点。方法通过对80例髁状突骨折病历资料的调查,对髁状突骨折的发生年龄、性别、致伤原因、骨折类型、合并伤、治疗及后遗症进行分析。结果髁状突骨折好发于20～30岁;男性多于女性,交通事故伤(52·5%)为主要致伤原因;髁状突骨折70%发生在髁颈部;40%合并颏部骨折;儿童髁状突骨折71·55%采用保守治疗,高位(囊内)骨折71·22%摘除骨折断端;3·75%继发关节强直。结论髁状突骨折好发于髁颈部,髁状突矢状骨折及髁颈部骨折伴骨折断端和关节盘移位严重的骨折处理不当易发生关节强直。

Objective To analyze the causes,clinical characteristics and treatment of condylar fractures.Methods A retrospective study was conducted in 80 cases with condylar fractures on the sex,age,cause,fracture characteristics,complicated inury,treatment and sequela.Results Condylar fractures occurred mainly in the male,and in 20-30 years old age.The traffic accident(52.5%) was the leading cause of condylar fractures.Condylar neck was the most fracturesite.57.36% of the case had complicated parasymphysis fracture.The child condylar fracture(71.55%) used the con-servative treatment.4.13% of the case occurred TMJ ankylosis.Conclusion Condylar neck was the most fracturesite.Traffic accident was the main cause of condylar fracture,and fracture occurred mainly in yong adult males.The TMJ anky-losis could happen if the serious dislocation of the condylar segment with meniscus and ascending of the ramus occurred.
