目的 :探讨导航系统应用于椎管内外肿瘤切除手术的临床意义。方法 :自 2 0 0 1年 3月至 2 0 0 1年 9月我院在导航系统 (Stealthstationsystem)辅助下共施行了 14例椎管内外肿瘤切除术。 结果 :本组患者均达到手术全切 ,术后恢复良好 ,无手术致残。结论 :应用计算机辅助导航系统切除椎管内外肿瘤的手术定位精确 ,可减少损伤、缩短手术时间 ,提高外科医生对手术部位及相邻脊柱解剖结构的辨别能力。 Objective: To investigate the clinical significance of navigating system applied in tumor resection of spinal canal. Methods: From March 2001 to September 2001, 14 patients underwent spinal and internal tumor resection with the help of the Stealth System. Results: All the patients in this group achieved complete surgical resection, recovered well after surgery, and had no surgical disability. Conclusion: The accuracy of computerized navigation system for the removal of tumors in and out of the spinal canal can reduce the injury, shorten the operation time and improve the ability of the surgeon to distinguish the anatomic structures of the operation site and adjacent spine.
