摘　　要：目的探讨计算机辅助技术在小颏畸形颏部截骨整形术中的应用效果.方法对2015年7月至2018年1月就诊于整形外科医院的17例小颏畸形患者行截骨整形术,男5例,女12例,年龄17~32岁,平均24岁.术前均应用计算机辅助设计技术模拟手术,确定颏部截骨整形前移量、下降量和移动方向,并应用计算机辅助制造技术制作个性化导板,指导手术操作.对比术前计算机辅助设计和术后的CT头颅三维重建模型,评估术前设计的精确性.结果所有病例术后效果满意,颏部畸形得到了明显矫治.术前计算机辅助设计和术后CT头颅三维重建模型配比精确度高,颏前点的误差为(0.24±0.08)mm,颏下点的误差为(0.15±0.17)mm.结论应用计算机辅助设计技术可精确模拟手术,计算机辅助制造技术制作的个性化导板可精准指导手术操作,术后效果满意.Objective To discuss the efficacy of computer aided design (CAD) and computer aided manufacturing (CAM) in the treatment of microgenia by osseous genioplasty. Methods From July 2015 to January 2018, 17 cases (Male, n=5, Female, n=12), aged from 17 to 32 years, with the meanage of 24 years, were enrolled. All patients had microgenia, and underwent osseous genioplasty. Computed tomography (CT) was performed preoperatively and 7-10 days postoperatively for all cases. Based on preoperative CT data, CAD was applied to make individualized surgical plan, surgery simulation, todetermine the movement of mentum. CAM was used to prefabricate the individualized surgical templates and transfer the CAD into intraoperative guidance. The registration of CAD and postoperative CT were performed to evaluate the surgical accuracy. Results All patients were satisfied with the surgical outcomes. The deformity of microgenia was significantly corrected. The Pg error was (0.24±0.08) mm, and the Me error was (0.15±0.17) mm. Conclusions The application of CAD increases the accuracy of surgical planning, and CAM provides areliable guidance with individualized template. Anoptimal surgical outcome can be achieved.
