摘　　要：目的建立"不对称指数"结合体积差的评估模式,并用于验证既往面部不对称患者的手术效果。方法选取面部不对称患者30例行激光扫描,在扫描所得图像上建立坐标系,并选取标志点,计算出各标志点面部不对称指数(AI);并利用镜面翻转技术计算体积差。对所得数据进行统计学分析,并得出最终结论。结果面部不对称患者术后各个标志点的AI均有不同程度的降低,体积差亦明显改善,提示治疗效果良好。结论 AI结合体积差的评估模式,能精确、直观、全面地评估面部不对称患者的手术效果,为手术方案的改进提供了可靠的参数。Objective To establish an evaluation system combining asymmetry index and volume difference aiming at the surgical effect of facial asymmetry patients. And to evaluate previous surgical treatment of facial asymmetry. Methods Thirty facial asymmetry patients were selected and their laser scan data were acquired. Coordinate was set up based on the data, mark points were picked, and asymmetry index （AI） for each point was calculated. Then volume difference was figured out with mirror flip technique. The acquired data was analyzed with statistical approach, then a conclusion was drawn. Results For facial asymmetry patients, the AI decreased with different levels for each mark point postoperatively, and the volume difference reduced markedly as well, indicating a significant treatment effect. Conclusion The evaluation system combining AI and volume difference can evaluate the surgical effect for facial asymmetry precisely, concisely and thoroughly, which offers a reliable guidance for the improvement of surgical treatment.
