下颌骨髁突骨折年龄和特点分析

目的探讨下颌骨髁状突骨折的发生特点与发病年龄的关系.方法对356例髁状突骨折病例的发生年龄、性别、致伤原因、骨折类型、合併伤等进行分析.结果髁状突骨折好发于20～30岁;男性多于女性,交通事故伤（46.91%）为主要致伤原因;按位置、移位和年龄分型共分为Ⅰ型223侧、Ⅱ71侧、Ⅲ三型149侧;61.24%合并颏部骨折.结论髁状突骨折中男性好发,交通事故是主要原因,年龄、致伤原因与骨折部位、移位相关.

Analysis between the Characteristics of Condylar Process Fractures and Age

Objective To explore the relation between the characteristics of condylar process fractures and patient＇s age.Method A retrospective study was conducted in 356 patients with condylar fractures on the age,sex,cause,fracture characteristics,concomitant injury,etc.Results Condylar fractures occured mainly in the male,especially in 20～30 years.Traffic accident（46.91%）was the leading cause of condylar fractures.According to the position and displace of condylar fracture and patient＇s age,condylar fracture was divided into 3 types,type I 223 condyles;type II 149 condyles;type III 149 condyles.Mental fracture was the main concomitant injury,up to 61.24%.Conclusions Traffic accident is the main cause of condylar fracture,and fracture occurred mainly in young males.The patient＇s age and the injury＇s cause are related to the position and displace of condylar fracture.
