摘　　要：目的:探讨Ⅱ类患者下颌前移术后双侧髁突变化的规律。方法:收集11例成人骨性Ⅱ类错牙合畸形患者,行双侧下颌支矢状劈开术(bilateral sagittal split ramus osteotomy,BSSRO)术前、术后的锥形束CT数据,利用Mimics软件测量分析横断面上双侧髁突角度及体积变化。结果:术前术后双侧的髁突角度没有显著差异,术后左侧髁突角度总体变化不明显,右侧髁突角度变大,并且双侧变化量差异具有统计学意义。双侧髁突术后体积减小,右侧变化显著大于左侧。结论:BSSRO改善患者Ⅱ骨性畸形术后,双侧髁突的变化表现出不一致性,右侧变化较左侧明显。Objective： To investigate the rule of the bilateral condylar changes in patients with skeletal class Ⅱ deformity after bilateral sagittal split ramus osteotomy. Methods： To take advantage of Mimics software to analysis the condylar angle in the axial plane as well as the condylar volumes of 11 patients pre-and post-surgery through their CBCT data. Results： The angle and volume changes both show that the change rate of right side were much more obvious than the left side.Conclusion： Patients with skeletal class Ⅱ deformity after BSSRO,their bilateral condyle shows unparallel changes,and the right side is more significant.
