下颌骨髁突骨折临床30例病例观察

目的:对30例(38侧)髁突骨折临床资料分析,探讨髁突骨折的临床特点。方法:选取大连市口腔医院口腔颌面外科2004-05─2007-10收治的资料完整的30例(38侧)髁突骨折病例,对髁突骨折的发生年龄、性别、致伤原因、骨折类型、全身损伤、治疗方案及手术并发症进行分析,并以开口度、开口型、咬合关系、咀嚼力、面型等5个方面作为术后评价标准,进行综合评价分析。结果:髁突骨折男性多于女性,交通事故伤为最主要致伤原因;髁突骨折42.11%发生在髁突基部,36.84%发生在髁突颈部。主要治疗方法是坚固内固定,正颌手术方法(下颌升支垂直截骨术)等。并发症主要为开口型偏斜(4例),开口度30mm以下(1例),术后髁突吸收(1例)。结论:髁突骨折好发于髁突颈部及基部,坚固内固定是最常用手术方法,牵引成骨技术也应用到陈旧性髁突骨折中。
