摘要2015年11月至2016年1月,收治2例成年男性颌面部多发骨折患者.术前行颌面部三维重建,并将数据输入三维打印机,制成与患者颌面部1:1的模型,在模型上模拟骨折手术及骨折固定材料预成型,手术中利用计算机辅助导航技术实时导航,术后与模型对比,面部多发骨折被准确复位固定,手术时间明显缩短,术后面部外形和咀嚼功能恢复良好.可见,三维打印结合计算机辅助导航技术可以提高颌面部多发骨折手术的精确性,并达到良好的修复效果.

abstractsFrom November 2015 to January 2016, two patients with multiple maxillofacial fractures were chosen to undergo CT scanning and maxillofacial three-dimensional ( 3D ) imaging reconstruction. The data were input to 3D printer in order to yield rapid prototyping model with the same size of patients′ maxillofacial regions. Simulated fracture surgery and reconstruction of the Ti-palate were performed on the models. The operations were conducted with the guidance of navigation system. The consistency of simulated model and real fractures was compared. The results show the complex maxillofacial fracture could make the operation more accurate and shorten the operation time. Moreover, the facial features and masticatory function of both patients were improved. The 3D printing technique combined with computer-assisted navigation could be applied to complex maxillofacial fractures surgery, in order to improve the surgical accuracy and achieve effective reconstruction.
