摘　　要：目的:观察改良下颌升支矢状劈开截骨术在矫治下颌骨畸形中的应用效果。方法:6例下颌骨畸形患者中单纯下颌前突畸形3例,前突伴偏颌畸形2例,继发性偏颌畸形1例。X线头影测量SNA为79°～83°,SNB为80°～88°,ANB为-5°～-2°。采用改良口内进路下颌升支矢状劈开截骨后退术,并配合术前、术后正畸治疗。结果:创口均一期愈合,无严重并发症发生,病例均获得协调的上下牙颌关系和满意的面部形态。结论:口内进路下颌升支矢状劈开截骨术配合正畸治疗是治疗下颌骨畸形的有效方法,值得临床推广应用。Objective：To investigate the effects of the modified sagittal split ramas osteotomy in treatment of mandibular deviation. Methods：Six mandibular deviation cases were included in this study,there were 3 cases with simply deformity ,2 cases with protrusion and partial jaw deformity and 1 case with partial secondary jaw malformation. SNA, SNB and ANB by X-ray cephalometric measurement were 79° -83°, 80°- 88° and -5°-_ -2°, respectively. All patients were operated with the modified sagittal split ramas osteotomy combined with preoperative and postoperative orthodontic treatment. Results ：Wound healing had no serious complications and the relations of the upper and lower tooth jaw and facial morphology were good. Conclusions ：Treatment of mandibular deviation with the modified sagittal split ramas osteotomy combined with orthodontic treatment is a effective way,which is worthy of being widely applied in clinic.
