双颌手术同期植骨矫治唇腭裂术后严重双颌畸形

目的:总结分析高位Le Fort Ⅰ型截骨术与下颌升支矢状劈开截骨术联合应用,配合牙槽嵴裂植骨术矫治唇腭裂术后严重双颌畸形的手术设计与效果.方法:2002年1月～2006年4月,共收治18例唇腭裂术后严重双颌畸形患者,男8例,女10例.年龄16～33岁,平均24.5岁.单侧唇腭裂15例,双侧3例.影像学检查均有继发严重双颌畸形的主要表现.均联合应用高位Le Fort Ⅰ型截骨术和下颌升支矢状劈开截骨术,同期行牙槽嵴裂自体髂骨游离移植Ⅰ期手术矫正.结果:术后伤口均Ⅰ期愈合.复查头部X线片,所有患者上、下颌骨位置均得到明显改善.随访6个月～3年,牙弓外形良好,X线片示无明显骨质吸收,植骨区密度与周围接近.18例均获得满意面容及良好的<牙合>关系. 结论:高位Le Fort Ⅰ型截骨术与下颌升支矢状劈开截骨术联合应用,配合牙槽嵴裂植骨术可以Ⅰ期矫治唇腭裂术后严重双颌畸形,并可以获得满意的手术效果.不但可以减少手术次数,而且还降低了手术费用,是矫治唇腭裂术后严重双颌畸形的一种有效方法.
