Abstract：
The aim of this study was to investigate the underlying causes of the need for redo orthognathic surgery, address surgical strategies, and evaluate postoperative outcomes. A retrospective chart review was conducted involving patients who underwent redo orthognathic surgery between January 2018 and April 2020. A total of 32 patients were included in this study. Prior to the procedures, patients\' chief complaints were unfavorable facial profile, asymmetry, relapse, malocclusion, obstructive sleep apnea, and long face. To address these issues, we performed redo orthognathic surgery: this resulted in satisfactory aesthetic and functional outcomes in most cases. Considering the challenging nature of a redo orthognathic surgery, it is crucial for surgeons to accurately evaluate the patient\'s chief complaints and tailor individualized surgical plans to meet the patient\'s expectations.
摘要：
这项研究的目的是调查需要重做正颌手术的根本原因，解决手术策略，并评估术后结果。对2018年1月至2020年4月期间接受重做正颌手术的患者进行了回顾性图表审查。本研究共纳入32例患者。在程序之前，患者的主要主诉是不利的面部轮廓，不对称，复发,错牙合,阻塞性睡眠呼吸暂停,长脸。为了解决这些问题,我们进行了重做正颌手术:在大多数情况下,这导致了令人满意的美学和功能结局.考虑到重做正颌手术的挑战性，对于外科医生来说，准确评估患者的主诉并制定个性化的手术计划以满足患者的期望是至关重要的。
