Preoperatively and postoperatively computed tomographic scanning was performed in every patient. For the CAD treatment group, firstly, the 3D graph of the patient's skull was built based on the CT data using the reconstructing function of Mimics 8.11. Then the 3D file was imported to Geomagic 4.0. The injury lateral was resected and replaced by the mirror of the intact side, so an intact skull was generated at last. Consequently, a model was manufactured in a technical machine. The last step was to prebend the titanium mesh on the model.

CAD/CAM治疗组是利用术前诊断CT，将DICOM格式CT数据输入图像处理软件Mimics8.11，由软件生成颅颌面骨STL格式的三维图像文件，应用另一个图像处理软件Geomagic4.0读取该文件，并应用镜像工具以中线为轴线生成健侧半的镜像，最终得到双侧对称的颅颌面模型，将该图像信息输入快速成型系统，通过逐层树脂堆积，生成树脂头模。
