摘要
目的根据患者头颅CT扫描数据,利用快速成形技术,构建三维头颅模型,评价基于头颅模型的模型外科在颅颌面畸形诊断治疗中的应用价值。方法对12例复杂颅颌面畸形患者进行电子束CT扫描,数据三维重建,应用计算机辅助制造技术制作三维头颅模型,进行术前测量,手术模拟操作,并预制骨缺损修补体,置入物塑形模板。结果在头颅模型上进行的模型外科操作与真实手术吻合程度很高,预制的修补体以及置入物塑形模板能够缩短手术时间,改善术后效果。结论基于三维头颅模型的模型外科对严重颅颌面畸形的诊断治疗具有良好的辅助作用。
Objective This study was to construct a geometric skull model with 3-dimension scanning and rapid-prototyping（RP） technology and also to evaluate the significance and further application of surgery simulation in the treatment of complex craniomaxillofacial malformation. Methods Twelve patients with complex craniomaxillofacial malformation were involved. The data obtained with CT scanning were transferred to a personal computer for surface rendering 3-dimention reconstruction. A geometric model was manufactured by selective laser sintering using rapid-prototyping device. Surgery simulation was performed both on the model and in the computer. Accordingly, a custom implant and an implant template, when needed, were constructed with the computer- aided design （CAD） and prefabricated with computer- aided manufacture （CAM） process. Results Surgery simulation made the operation shorter, the complications lower and the outcome better. Conclusions Skull model provides great convenience in the treatment of cranio-maxillofacial malformation.
