目的探讨基于骨组织标志点三维坐标的测量分析法在颅面骨骼畸形患者实施轮廓整复术中的作用.方法将CT数据导入Mimics 10.0软件,调整头颅三维模型在系统坐标系内的位置,使得眶耳平面与坐标系的水平面平行,中矢状面与坐标系的中矢状平面重叠.在三维模型上标记测量点并提取其三维坐标值,分别获取两侧对应测量点三维坐标相对于系统中矢状面的三维差值,以测量结果为指导分块截除多余病变骨,实施轮廓整复手术.结果三维CT测量分析可以全面评估畸形程度,获得面部骨骼对称结构在三维方向上的差异,以测量结果为指导实施轮廓整复术14例,手术时间缩短,出血量减少,术后容貌明显改善.结论三维CT测量分析可提高手术准确性和安全性,有利于恢复面部对称性,为术前规划和实施精确手术开辟了新思路.

Objective To investigate the quantitative analysis based on three-dimensional computed tomography (3D-CT) in contouring surgery of complex craniofacial fibrous dysplasia (FD).Methods 14 patients with craniofacial FD underwent 3D-CT scan.Axial images of patients with craniofacial FD were reconstructed into 3D model by using Mimics 10.0.Anatomical landmarks were located and the coordinate of the landmarks obtained.The differences between the right landmarks and the left were calculated and analyzed.Quantitative contouring surgery was performed based on the quantitative analysis result.Results With the detail data from the 3D-CT analysis,the surgery of contouring was more safe and accurate with less operation time,less bleeding and good results.Conclusions The method of 3D CT quantitative analysis can provide precise information in the diagnosis and treatment planning of craniofacial deformity.Based on the result of 3D-CT quantitative analysis,the operations can be performed more accurately and safely with good symmetric consequence.
