对称性是影响人脸吸引力的重要因素之一。因此，它的修复是口腔颌面外科的一项重要任务。直到最近，大多数客观量化面部不对称性的技术都是基于二维数据（即照片）的评估。这些技术在文献中得到了很好的建立，并且共同点是手动识别面部中的几个地标，并将其放在公式中以获得面部不对称值。随着三维测量系统的日益普及，基于面部表面的密集三维点云，可以对面部对称性进行自动三维分析。该分析的结果一方面是镜面，其最好地满足面部关于正中矢状面的部分对称性，另一方面是量化整体面部不对称特征的3D不对称指数。本文对三种二维分析方法和一种三维分析方法进行了比较。(C)2014年欧洲颅颌面外科协会。由爱思唯尔有限公司出版。保留所有权利。
Symmetry is a significant factor, among others, influencing the attractiveness of human faces. Hence its restoration is an essential task in oral and maxillofacial surgery. Until recently, most of the techniques to objectively quantify the facial asymmetry were based on the evaluation of two-dimensional data, i.e. photographs. These techniques are well-established in literature and have in common that several landmarks in the face are identified manually and put together in a formula to obtain a facial asymmetry value. The increasing availability of three-dimensional measuring systems offers the possibility to perform an automated 3D analysis of the facial symmetry based on a dense 3D point cloud of the facial surface. The results of this analysis are on the one hand a mirror plane, which meets best the partial symmetry of the face regarding the median sagittal plane, and on the other hand a 3D asymmetry index quantifying the overall facial asymmetry characteristics. In this paper three selected 2D analysis methods and one 3D analysis method are compared. (C) 2014 European Association for Cranio-Maxillo-Facial Surgery. Published by Elsevier Ltd.
