目的：利用计算机辅助导航技术，提高颞下颌关节侧方成形术的精确性和安全性。方法7例单侧颞下颌关节强直的患者，在导航辅助下进行颞下颌关节侧方成形术。通过术前手术规划，确定截骨的位置和范围。将术前手术规划的数据输入导航系统，用于术中导航。术中观察导航系统的实时性和精确性。测量和比较术前、术中及术后最大张口度的变化。术后随访观察患者并发症及复发情况。结果术前手术规划能够在导航系统工作站中顺利完成。利用探针或手术工具的实时导航，所有颞下颌关节侧方成形术均顺利完成。术前的平均最大张口度为7.0 mm，术中为37.9 mm，而术后为36.7 mm。术后随访观察，患者的功能和形态都得到了很大的改善，未发现并发症和复发情况。结论对于复杂的颞下颌关节侧方成形术，计算机辅助导航技术的应用将提高其精确性和安全性。

Objective To improve the accuracy and safety of lateral gap arthroplasty of temporomandibular joint by applying computer -assisted navigation. Methods Seven patients with unilateral temporomandibular joint ankylosis underwent the navigation-guided lateral gap arthroplasty. Preoperative planning was performed to determine the osteotomy line and extent of ankylosed bone to be resected. The data of preoperative planning were inputted into the navigation system. During the operation, the real-time and accuracy of navigation system were observed. Maximum mouth opening was measured and compared preoperatively, intra-operatively and postoperatively. Patients were monitored for complications and signs of recurrence in the follow-ups. Results Preoperative planning was performed successfully at the workstation of navigation system. All navigation-guided lateral gap arthroplasty were completed by using real-time pointer-based or instrument-based navigation. Measurements illustrated that the mean of maximum mouth opening was 7.0 mm preoperatively, 37.9 mm intra-operatively and remained 36.7 mm postoperatively. Follow-up evaluation showed remarkable improvement in function and esthetics, and no complications and signs of recurrence were observed. Conclusion Computer-assisted navigation in lateral gap arthroplasty of temporomandibular joint could improve the accuracy and safety.
