摘　　要：目的 通过分析锥形束CT辅助下颌骨升支矢状劈开术在正颌外科治疗中的作用,为科学规范地开展正颌外科手术提供参考.方法 对2012年7月至2014年4月收治的31例下颌骨骨性错（牙合）患者进行回顾性研究,患者术前、术后进行锥形束CT头影测量及三维重建,结合传统正颌外科术前设计,分析下颌骨升支矢状劈开术在骨性错（牙合）治疗中的应用.结果 除1例患者外形欠满意外,其余患者的容貌及咬（牙合）得到明显改善,患者满意率达96.8％.结论 在行下颌骨升支矢状劈开术前运用锥形束CT结合传统的正颌外科术前设计,可以设计个体化的手术方案,明显改善骨性错错（牙合）患者的容貌及咬（牙合）关系.Objective To analyze the role of CBCT assisted sagittal split raum osteotomy in orthognathic surgery to provide a reference for conduct orthognathic surgery more scientifically and normally. Methods A retrospective study was conducted on 31 patients with dentofacial deformity in our hospital from Jul 2003 to Apr 2014. Preoperative and postoperative Cone-beam cephalometry and CT reconstruction were performed in all ca- ses. The design of preoperative orthognathic was carried out by combining traditional method and the application of sagittal split raum osteotomy in orthognathic surgery was also analyzed. Results All patients were satisfactory with the results both in appearance and occlusion except one with unsatisfactory aesthetic result. The satisfac- tion rate was 96.8%. Conclusion The cone-beam computed tomography combined with preoperative design of orthognathic surgery were used to perform individual design before sagittal split raum osteotomy, which could obviously improve the appearance and occlusion of patients with dentofacial deformities.
