Distraction osteogenesis is an alternative treatment option for patients with facial asymmetry and mandibular hypoplasia. New bone is formed between bone segment surfaces that are gradually separated by incremental traction. The purpose of this article is to report the treatment of a 22-year-old man with hemifacial microsomia, facial asymmetry, and a skeletal Class II profile. The patient's left mandibular ramus was lengthened with distraction osteogenesis, and miniscrew-assisted rapid palatal expansion was used to correct the maxillary transverse deficiency. Postoperative orthodontic treatment achieved tooth alignment and closure of the posterior open bite. The total treatment period was 27 months. These therapeutic treatments improved the patient's facial appearance.
牵引成骨术是治疗面部不对称和下颌骨发育不全患者的一种替代治疗选择。新骨在逐渐分离的骨段表面之间形成。本文旨在报告一例 22 岁男性患者的治疗情况，该患者患有单侧颜面短小症、面部不对称和骨骼 II 类错颌。患者的左侧下颌升支通过牵引成骨术延长，并用微型螺钉辅助快速腭扩张来矫正上颌横向发育不足。术后正畸治疗实现了牙齿的排齐和后牙开颌的关闭。总治疗期为 27 个月。这些治疗方法改善了患者的面部外观。
