【摘要】 目的　发育性下颌骨不对称畸形是常见的牙颌面畸形之一 ,临床治疗难以取得满意疗效。通过对发育性下颌骨不对称畸形治疗的回顾性研究 ,探讨正颌手术和正畸联合矫治对于提高疗效、减少复发的临床意义。方法　按术前正畸 -正颌手术 -术后正畸的模式 ,对 5 8例发育性下颌骨不对称畸形患者进行矫治 ,行单颌手术、双颌手术、颌骨整形、颏成形术、牵引成骨术共计 82例次 ,设计三级疗效评定标准对手术效果进行评价。结果　经过正畸、正颌联合矫治的发育性下颌骨不对称畸形 5 8例 ,满意 5 3例 (91.4 % ) ,基本满意 4例 (6 .9% ) ,不满意 1例 (1.7% ) ,该例经二次手术得以矫正。结论　发育性下颌骨不对称畸形的矫治必须坚持正颌与正畸的紧密配合 ,通过严格的术前术后正畸 ,可达到改善面形、恢复牙合关系、提高矫治效果 ,减少畸形复发的目的。更多还原

【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.更多还原
