摘　　要：目的模拟下颌角整形术,将逆向工程原理应用于下颌角整形手术设计中。方法重建病人术前头部CT颅骨模型,测量相关数据并导入geomagic(V5)软件中,根据东方经典美丽分析面罩模拟下颌骨整形手术,比较原始模型与模拟后模型以确定截骨线和截骨量,最后重建术后CT模型,评价模拟手术效果。结果重建了不同状态下颌骨三维模型,利用模拟手术结果设计了实际手术方案。结论逆向工程原理对于设计下颌整形术方案有明显的临床应用价值。Objective To carry on virtual mandibular angle reduction plasty, and apply reverse engineering to the design of mandibular angle reduction plasty. Methods Reconstruct the 3 D model of skull with patient＇ s CT data before operation. After measure items concerned, import the model into the software geomagic（V5） and simulate mandibular angle reduction plasty under the direction of orient classical beauty-analyzing veil. Compare original model with the simulated to determine osteotomy-line and osteotomy-volume. Evaluate effect of virtual operation with the 3D model rebuilt on CT data of after-operation. Results Reconstruct mandibula models under different conditions, and design surgery programme with the results of virtual operation. Conclusion Reverse engineering has great clinical application value in the design of mandibular angle reduction plasty.
