Traditionally, cephalograms have been used to evaluate a patient's maxillofacial skeleton and facial soft-tissue morphology. However, magnification and distortion of the cephalograms make detailed morphologic analysis difficult in patients with complex deformities. The purpose of this article was to introduce a new method for visualizing deformation and deviation of the maxillofacial skeleton and facial soft tissues.
Standard 3-dimensional Japanese head models were sized to match the sella-to-nasion distance obtained from 2 patients' (1 man, 1 woman) maxillofacial skeletal images. Then, the scaled standard model was superimposed on each patient's 3-dimensional computed tomography image.
This system provided clear shape information independent of size and facilitated the visualization of shape variations in maxillofacial skeletal and facial soft-tissue morphology.
This method will be useful for 3-dimensional morphologic analysis of patients with jaw deformities.
传统上，头影测量片一直用于评估患者的颌面骨骼和面部软组织形态。然而，头影测量片的放大和失真使得对复杂畸形患者进行详细的形态学分析变得困难。本文的目的是介绍一种可视化颌面骨骼和面部软组织变形及偏差的新方法。
将标准的三维日本头部模型进行尺寸缩放，以匹配从2名患者（1名男性，1名女性）的颌面骨骼图像中获得的蝶鞍至鼻根点距离。然后，将缩放后的标准模型叠加在每位患者的三维计算机断层扫描图像上。
该系统提供了独立于尺寸的清晰形状信息，并有助于可视化颌面骨骼和面部软组织形态的形状变化。
该方法将有助于对颌骨畸形患者进行三维形态学分析。
