【摘要】 目的探讨广东省河源市颌面部骨折特征改变与时间的关系。方法回顾性分析过去20年广东省河源市颌面部骨折病例,对骨折发病率、发生原因、类型、部位及与经济发展的关系进行研究。结果 20年间共有361例患者诊断为颌面部骨折,其中1990～1999年75例,2000～2009年286例,后10年骨折发生率明显上升。前10年颌面骨折主要原因为暴力,而后10年则是交通事故。发生骨折的人群主要是男性,好发年龄为20～30岁。结论随着时代的变迁,交通事故替代暴力袭击成为颌面部骨折的主要原因,最常见的骨折类型为单纯性面中部骨折,最好发的部位为鼻骨,其次为下颌骨和上颌骨。不同地区骨折发生原因、骨折部位和类型差异较大。骨折发生率与机动车拥有量密切相关。更多还原
