计算机辅助颅颌面畸形的三维诊断

Computer Aided Three Dimensional (3 D) Diagnosis of Craniomaxillofacial Deformity

利用侧位Ｘ线头影测量对颅颌面畸形进行诊断分析，已有相当长的时间．但因该方法取自颅颌面结构左右两侧的均值，用其测量分析不对称颅颌面畸形，有很大局限性．本文报告一种将正位和侧位两张Ｘ线头影片结合起来的三维Ｘ线头影测量分析方法，以及标准化与个体化相结合的诊断方法在复杂、不对称颅颌面畸形诊断中的应用．

It is a long time to diagnosis and analysis craniomaxillofacial deformities with lateral cephalogram.The lateral cephalometric analysis,that bases on average data of skull left and right structures,has a limitation to analyze the asymmetric craniomaxillofacial deformities.This paper reports a three dimensional cephalometric method and its application on diagnosis of the complex asymmetric craniomaxillofacial deformity.
