ABSTRACT

Objective Developmental mandibular asymmetry is a common deformity in the human craniofacial skeleton and the treatment is not easy to get satisfactory results. A retrospective study was performed to investigate the clinical results and stability after treatment of developmental mandibular asymmetry by using combination of orthognathic surgery with orthodontics. Methods 58 cases of developmental mandibular asymmetry were treated by preoperative orthodontics-orthognathic surgery -postoperative orthodontics procedure. 82 times of operation, such as mandibular osteotomy, bimaxillary osteotomy, jaw plastic surgery, genioplasty, and distraction osteogenesis were performed according to different type of asymmetry. The facial appearance and occlusion relationship were evaluated with 1～4 years of follow-up. Results Satisfactory results were achieved in 53 cases (91.4 %). Primary satisfactory results were obtained in 4 cases (6.9 %). 1 case (1.7 %) with unsatisfactory result obtained aesthetic effect and ideal occlusion after operation again. Conclusions It is essential to use both of orthodontics and orthognathic surgery in order to ameliorate facial appearance, resume occlusal function, achieve good corrective result and prevent the recurrence of the developmental mandibular asymmetry.
