摘要
目的 总结正颌外科矫正颌骨畸形的临床经验。方法 对600例颌骨畸形患者进行正颌外科手术,其中上颌Le FortⅠ截骨与下颌体部截骨术212例,单纯上颌Le Fort Ⅰ截骨56例,单纯双下颌升支矢状劈开截骨(SSRO)30例,下颌体部截骨145例,行Downfracture或Wassmund法矫治112例,下颌前突伴偏颌畸形行下颌体部截骨45例。结果 60X例中术后部分复发28例,完全复发2例,下唇感觉异常9例,术后感染6例,其余术后面容和咀嚼功能获得满意效果。结论 上颌Le Fort Ⅰ截骨与下颌体部截骨术能较好地矫正上颌后缩及下颌前突畸形,但牙颌关系恢复不良。前牙根尖下截骨是纠正双颌前突畸形的理想术式,SSRO矫正下颌前突畸形效果满意。
Objective To evaluate orthognathic surgeies for the treatment of detofacial deformities. Methods The medical records of 600 cases with dentofacial deformities were summed up and analysed from aspects of an operation and postoperative effects. Results The 600 cases with dentofacial deformities were corrected by the orthognathic surgery,of which 212 with maxillary retrusion and mandibular prognathism were treated by Le Fort I osteotomy and mandibular body osteotomy, 56 with maxillary retrusion by Le Fort I osteotomy;30 with mandibular prognathism by sagittal split ramus osteotomy(SSRO) , 145 with mandibular prognathism by mandibular body osteotomy; 112 with maxillary and mandibular prognathism or with maxillary prognathism by Downfracture or Wassmund; 45 with mandibular prognathism and asymmetry by mandibular body osteotomy. The complications were relaps, postoperative infection and permanent sensory losses. Conclusion The long-term results showed that Le Fort I osteotomy and SSRO for the correction of dentofacial deformities effective methods methods.
