目的：分析正畸正颌联合治疗的颜面不对称患者头颅定位后前位片测量指标的非对称性。方法选取不同程度颜面不对称患者45例，对所有患者治疗前后头颅定位后前位片进行测量，采用单样本t检验将治疗前测量指标的非对称率与个别正常人群的非对称率进行比较，通过相关系数的分析，归纳出颜面不对称患者倾向于采用正畸正颌联合治疗的测量指标，并得出其参考值。同时通过配对t检验比较治疗前后测量指标非对称率的差异。结果有14项指标治疗前的非对称率与个别正常人群的非对称率相比差异有统计学意义（P<0.05）。45例患者中与Me[X]具有较高直线相关关系的指标为Ag[X]。28例患者以下颌骨体部不对称为主，15例患者以下颌升支不对称为主，2例患者同时存在下颌体部和下颌升支的不对称。Me[X]等15项测量指标治疗前后差异均有统计学意义（P<0.05）。结论颜面部的不对称主要集中在面下1/3，以下颌体部不对称为主要表现。当与Me[X]具有高度直线相关关系的指标Ag[X]的非对称率大于参考值下限11.31%，Go[X]的非对称率大于参考值下限9.79%，且Me[X]大于参考值下限5.2mm时，该患者的治疗方案更倾向于正畸正颌联合治疗。

Objective To analyze the asymmetry of measurements in facial asymmetry patients with skull positioning posterior-anterior radiographs after orthodontic-orthognathic treatment. Methods Posterior-anterior cephalometric radio-graphy and cephalometric analysis were performed in forty-five patients with different degrees of facial asymmetry. A single sample t-test was conducted to compare the asymmetry of measurements before treatment and individual normal occlusion. The measurement and reference values in facial asymmetry patients who underwent orthodontic-orthognathic treatment were summated by analyzing the correlation coefficient. The paired t-test was employed to compare the difference between the two groups before and after the treatment. Results Fourteen measurements were significantly different before the treatment and individual normal occlusion (P<0.05). Me[X] exhibited a higher correlation index of Ag[X] in forty-five cases. Twenty-eight patients showed the main asymmetry in the mandibular body, whereas fifteen patients in the ramus. Two patients showed the main asymmetry in both mandibular body and ramus. Fifteen measurements were significantly different before and after the treatment (P<0.05). Conclusion Facial asymmetry is mainly concentrated in one-third of the surface, primarily manifested in the mandibular body. Orthodontic-orthognathic treatment is preferred when Ag[X] is greater than the minimum reference value of 11.31%, Go[X] is greater than 9.79%, and Me[X] is greater than 5.2 mm.
