摘　　要：目的:建立活体单侧眼眶部缺损的面部三维数字化模型,探讨颜面部缺损三维数据快速精确采集的新方法。方法:采用位相测量轮廓技术对患者面部进行活体测量,获得三维点云数据,运用CloudForm反求工程软件对点云数据进行处理后,转化为相应的数字化文件格式,在Geomagic实体构造软件中重建缺损面部三维数字化模型。结果:实现了单侧眼眶部缺损面部组织的活体三维重建,取得的面部模型数据清晰可靠。结论:应用位相测量轮廓术可快速安全的重建缺损面部的真实三维形态,为眼眶部缺损的计算机辅助设计奠定了基础。Objective： To build 3-D digital face model of unilateral orbital defect and find a new method to get 3-D data of facial defects. Methods： Phase measuring profilometry was used to get the primitive point data of unilateral orbital defect, and then the original point data were dealed with the three-dimensional design software in order to acquire a 3-D digitizing face model. Result： A 3-D digitizing face model of unilateral orbital defect was successfully reconstructed by this method. Conclusion： The phase measuring profilometry was fast and safe to get an actual 3D image of facial defects, and would be helpful to the computer-aided design of unilateral orbital defect restoration.
