摘　　要：目的分析临床中正畸正颌联合治疗颜面不对称患者头颅定位后前位片的非对称性。方法回顾性分析2013年6月-2014年6月采用正畸正颌联合治疗的50例不同程度颜面不对称患者资料,对治疗前后测量头颅定位后前位片指标的非对称率与同期进行体检的50名正常人的非对称率进行对比分析。结果上颌指标:L 2、L 3、L 4、L 5、L 6、L 7、L 8、L 9、L 10非对称率与正常值差异均有统计学意义(P<0.05);治疗前后L 3、L 6、L 7、L 10非对称率差异均有统计学意义(P<0.05)。下颌指标:L 1、L 3、L 4、L 5、L 6、L 7、L 8、L 9、L 10非对称率与正常值差异均有统计学意义(P<0.05);治疗前后L 1、L 3、L 4、L 5、L 6、L 7、L 8、L 9、L 10非对称率差异均有统计学意义(P<0.05)。结论临床中颜面不对称患者主要体现在面下的1/3位置,颜面下颌体部不对称最为明显。Objective To analyze the asymmetry of posterior-anterior radiograph of patients with facial asymmetry after orthodontic and surgical treatment.Methods We retrospectively analyzed the clinical data of 50 patients with varying degrees of facial asymmetry treated with orthodontic and surgical methods between June 2013 and June 2014.The asymmetric rate of posterior-anterior radiograph of the patients before and after treatment were compared with that of another 50 healthy subjects.Results Maxillary indexes including L2,L3,L4,L5,L6,L7,L8,L9,and L 10 asymmetric rates of the patients were significantly different from those of the normal subjects（P〈0.05）;L3,L6,L7 and L 10 asymmetric rates were significantly different before and after treatment（P〈0.05）.Mandibular indexes including L1,L3,L4,L5,L6,L7,L8,L9,and L 10 asymmetric rates were significantly different from normal indicators（P〈0.05）;L1,L3,L4,L5,L6,L7,L8,L9,and L 10 asymmetric rates changed significantly after treatment（P〈0.05）.Conclusion Clinical facial asymmetry mainly manifests on the bottom 1/3 part of the face,and facial mandibular asymmetry is the most obvious.
