摘要
目的 探讨利用计算机辅助设计与制造（CAD／CAM）技术进行个体化塑形颅骨缺损修补术的临床价值。方法 2004年5月-2006年3月收治颅骨缺损患者32例，将患者颅骨缺损前后CT数据在计算机上分别进行三维重建，采集颅骨缺损部位的三维几何模型数据，应用人工智能技术，设计补片几何形状，制作出凹凸两个模具，利用模具将颅骨修补材料钛网压制成形，用成形好的钛网修补颅骨缺损。结果 术中医师塑形工作量、麻醉及手术操作时间明显减少，术后无一例出现因塑形欠佳造成的并发症，复查头颅CT修复后的颅骨形状与原颅骨形状完全一致。结论 颅骨缺损修补手术应用CAD／CAM技术塑形颅骨修补材料实现了按人配置修补颅骨缺损，使患者颅骨缺损修补后头颅形状恢复生理原貌，患者满意度100％，此方法值得应用与推广。
Objective To study the clinical value of computer-aided designation （CAD） of individual shaped titanium armor plate in repairing skull defects. Methods Thirty-two patients who suffered from skull defect were treated and cured in my hospital from May 2004 to March 2006. The CT data were distinguishly 3-D reconstructed before and after cranieetomy, so we got 3-D geometric model of skull defect. Then, we designed a geometric shape of patch and made the dice of both concavity and convex by intellectual technology, finally we got the dice to shape titanium armor plates before operation. Results Neurosurgeons/shaping workload, anaesthetic and operational time were decreased significantly compared to traditional handwork shaping. There was no complication for the shaping below the mark. Thirtysix patients regained original shapes of cranial bones. Conclusions We implemented individual treat- ment to repair skull defect by CAD/CAM. The satisfaction rate of patients approaches 100% after operation. So it is a good method and can be recommended clinically.
