计算机辅助外科在颅颌面部骨纤维异常增殖手术中的应用

Application of computer-aided surgery in fibrous dysplasia of cranio-maxillofacial bone

目的：探讨计算机辅助外科技术在颅颌面骨纤维异常增殖症手术中的治疗效果。方法：选择1999年1月-2012年12月接受诊疗的颅颌面骨纤维异常增殖症患者22例．根据患者的具体情况设计手术切除方案。利用计算机辅助外科技术制作头颅模型和导航模板，术后观察和评价疗效。结果：22例颅颌面骨纤维异常增殖症患者部分切除病变骨质，基本恢复面部对称，随访6～36个月，效果满意。结论：计算机辅助外科通过术前设计、术中导航及术后预测，有助于提高颅颌面手术的准确性，缩短手术时间，恢复面部对称性，是一种安全、有效的颅颌面手术辅助方法。

PURPOSE： To evaluate the effect of computer-aided surgical techniques in surgical treatment of cranio- maxillofacial fibrous dysplasia. METHODS： Twenty-two patients from January 1999 to December 2012 with cranio- maxillofaeial fibrous dysplasia were treated in our department. According to the patients＇specific conditions, surgeons designed surgical programs, and used computer-assisted surgical techniques to produce skull model and navigation template individually. The effects after surgery were evaluated. RESULTS： Twenty-two patients with resection of the bone lesions restored facial symmetry partially. The patients were followed up for 3 to 36 months, and the treatment effects were satisfactory. CONCLUSIONS： With preoperative planning, intraoperative navigation and postoperative prediction, computer-aided surgery shows its great value in improving the accuracy of cranio-maxillofacial surgery, shortening operating time and restoring facial symmetry. It is regarded as a valuable and safe surgical technique in cranio- maxillofacial surgery. Supported by Beijing Natural Science Foundation （7112124）.
