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 L10 asymmetric rates of the patients were significantly different from those of the normal subjects (P < 0.05); L3, L6, L7 and L10 asymmetric rates were significantly different before and after treatment (P < 0.05). Mandibular indexes including L1, L3, L4, L5, L6, L7, L8, L9, and L10 asymmetric rates were significantly different from normal indicators (P < 0.05); L1, L3, L4, L5, L6, L7, L8, L9, and L10 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.
