摘　　要：目的建立能够准确、快速获得隆鼻术个性化数字化设计所需三维信息的测量系统。方法随机选取20例隆鼻患者,经激光三维扫描和CT扫描,分别建立激光三维数据来源的数字模型和CT三维数据来源的数字模型(简称激光模型和CT模型),将两种数字模型在图形工作站中同时打开,根据面部标志点进行拟合。结果激光模型能迅速、精确地完成头面部软组织的三维重建,CT模型可重建骨组织、软组织,并可拟合成患者面部的精确三维数据。结论通过激光三维扫描和CT扫描,可以准确、快速获得隆鼻假体数字化设计所需三维信息,对于隆鼻假体个性化数字化设计具有极好的应用前景。Objective To establish a measurement system, which can provide the 3D information immediately and accurately for nose implant. Methods Twenty patients were selected in random; and the figure model was established by 3D laser passing and CT scan. The two models were opened in the photo station at the same time; and then fitting was done according to the facial landmark points. Results By fitting, the precise 3D information of patient＇s faces. Conclusion Combining the information from laser passing and CT scan, the measurement system for designing digital nose implant could be get accurately and quickly. It is more valuable on the digital design of rhinoplasty.
