摘　　要：目的评价计算机模拟系统对骨性安氏Ⅲ类错畸形正颌术前预测的准确性及其临床应用价值。方法选择2011年1月至2013年1月到沈阳市口腔医院及中国医科大学附属口腔医院口腔颌面外科就诊的骨性安氏Ⅲ类错畸形患者30例,所有患者均拍摄术前、术后CT。利用计算机模拟系统模拟手术和面像预测,并与术后实际效果进行比较。结果 30例患者模拟预测与实际结果比较,所有软、硬组织测量参数差异均无统计学意义(P>0.05)。结论计算机模拟系统能够整合大量医学影像信息,直观模拟手术并预测手术后软、硬组织的变化,可为骨性安氏Ⅲ类错畸形患者正颌手术设计个体化最佳方案提供实用有效的技术及依据。Objective To evaluate the accuracy and potential advantages of computer-assisted simulation system in or- thognathic surgery. Methods Thirty patients with skeletal Angle Ⅲ were chosen and received preoperative and postop- erative CT. Computer-assisted simulation system was used for surgical simulation and preoperative facial appearance prediction. Results The difference between simulation and actual operation showed no statistical significance （P 〉 0.05）. Conclusion Computer-assisted simulation system can integrate various medical imaging data and simulate sur- gery. It can provide practical and effective techniques and scientific basis for establishing the preoperative planning of in- dividual optimal surgical procedure.
