数字化虚拟手术设计辅助正颌外科手术12例临床分析

Clinical analysis of 12 cases of orthognathic surgery with digital computer-assisted technique

目的:探索数字化技术在辅助正颌外科手术中的应用价值。方法:2008年1月—2011年12月间收治12例颌骨发育畸形患者,经CT扫描及三维重建,对12例患者进行手术治疗,并对结果进行评价。结果:经CT扫描,Mimics重建,能够清晰显示颌骨畸形的状态,通过在Mimics软件中虚拟手术,辅助术中导航,术后效果均满意。结论:数字化正颌外科手术能够提高手术操作的可预见性,便于医患沟通,缩短手术时间,减轻患者的痛苦。

PURPOSE： This study was to investigate the effect of the digital computer-assisted technique in orthognathic surgery. METHODS： Twelve patients from January 2008 to December 2011 with jaw malformation were treated in our department. With the help of CT and three-dimensional reconstruction technique, 12 patients underwent surgical treatment and the results were evaluated after surgery. RESULTS： Digital computer-assisted technique could clearly show the status of the jaw deformity and assist virtual surgery. After surgery all patients were satisfied with the results. CONCLUSIONS： Digital orthognathic surgery can improve the predictability of the surgical procedure, and to facilitate patients＇ communication, shorten operative time, and reduce patients＇ pain.
