Abstract

The advent of computed tomography has greatly reduced magnification errors from geometric distortions that are common in conventional radiographs. Recently introduced 3-dimensional (3D) software enables 3D reconstruction and quantitative measurement of the maxillofacial complex; 3D images are also useful in understanding asymmetrical structures. This article describes the use of 3D images in the diagnosis of facial asymmetry. A step-by-step procedure for 3D analysis developed by the authors is described by using the example of a 23-year-old man with a chin deviation to 1 side.

摘要

计算机断层扫描的出现极大地减少了传统X光片中常见的几何失真所导致的放大误差。最近推出的三维(3D)软件能够对颌面复合体进行三维重建和定量测量;三维图像在理解不对称结构方面也很有用。本文描述了三维图像在面部不对称诊断中的应用。通过一名23岁下巴向一侧偏斜男性的病例,介绍了作者开发的三维分析的逐步流程。
