摘　　要：选择6例颌面部畸形的患者,通过螺旋CT扫描获得所有颌面部畸形患者的影像资料,通过三维重建,采用计算机辅助测量、分析、手术模拟,最后确定手术方法。计算机辅助三维重建技术为6例颌面部畸形患者术前提供相对准确的诊断,通过辅助三维重建技术获得的图像弥补了普通X线及二维CT轴位图像不足,可以全面立体地显示病变,在正颌外科的术前诊断、手术计划制定及手术后效果评价中具有重要临床应用价值,可作为颌面常规的影像学检查方法,也是口腔计算机辅助外科的数据基础。Six patients of orthognathic osteotomies were included in this study. Orthognathic osteotomies image data were obtained by spiral CT scan. Surgical plan was determined by 3D reconstruction and computer-aided measure- ment, analysis and surgical simulation. The computer-assisted three-dimensional reconstruction technique could be used to provide relatively accurate clinical diagnosis and so cover the shortage of X-ray and two-dimensional CT axi- al images. Moreover, it could show disease in each aspect, and was of great value in preoperative diagnosis, surgi- cal plan making and surgical effect evaluation. Therefore, the computer-assisted three-dimensional reconstruction technique could be used for normal method of maxillofacial imaging examination. Moreover, this technique provides basic data for oral computer assisted surgery.
