腓骨瓣及CAD/CAM技术在重建下颌骨缺损中的应用

摘要/Abstract

摘要： 目的　探讨应用腓骨瓣及CAD/CAM技术修复大面积下颌骨缺损的经验。方法　根据16例患者下颌骨缺损的部位和特征，通过螺旋CT扫描获取缺损区的数据，在软件中应用CAD/CAM技术模拟下颌骨切除及重建手术，利用快速成型机加工制作出实物模型，依据模型对腓骨进行塑形、钛板重建，恢复下颌骨的形态和功能。结果　CAD/CAM技术的应用使术中截骨、腓骨塑形、定位速度明显加快；术后患者面部外形基本对称，影像学检查显示下颌骨缺损区的重建形态及固位良好；无严重并发症。结论　腓骨瓣联合CAD/CAM技术重建下颌骨缺损，能够明显缩短手术时间，提高手术质量，保证手术效果，是值得推广的重建下颌骨缺损的理想方法。

Abstract: Objective　To explore the application of mandibular defects reconstruction with fibula flap and CAD/CAM technology. Methods 16 patients with mandibular defects were selected. The digital data of defect area were obtained using CT scan technology according to the patients’ respective characteristics. The mandibular resection and reconstruction were simulated using CAD/CAM technology and the natural pattern was made with rapid forming machine. The fibula was shaped and Titanium plate was reconstructed based on the model to restore the morphology and function of mandible. Then the postoperative complication and recovery status were evaluated. Results　Application of CAD/CAM technology in mandibular defects reconstruction has quicken fibula osteotomy, shaping and positioning. The postoperative facial appearances were basically symmetrical and there were no obvious complications. Imaging diagnosis showed that the shape and position of the reconstructed mandible were good. Conclusion　Fibula flap reconstruction combining with CAD/CAM technology in treatment of mandibular defects have shown good effectiveness and it has shortened the time of surgical operation. It is a perfect technology and it’s worth promoting.
