    摘 要:目的 探讨在神经导航指导下，脑肿瘤及周围结构的定位和外科手术治疗效果. 方法 应用Stealth Station和Vector Vision神经导航系统，手术切除36例脑肿瘤，总结治疗效果，分析定位准确性与疗效的关系. 结果 36例脑肿瘤共36个，全切除35个(97%)、次全切除1个(3%).出院时患者症状明显改善29例(81%)、无明显变化7例(19%)、本组无症状恶化及死亡.平均注册误差和10cm预期准确性分别为(2.09±0.67)mm和(1.95±0.37)mm.术中持续准确性SA1，SA2和SA3分别为(2.02±0.95)，(1.03±0.48)和(1.15±0.98)mm. 结论 使用Stealth Station和Vector Vision神经导航系统，在术前可制定脑肿瘤手术计划，术中提供瘤体的动态跟踪和实时导航，手术定位准确、可靠，有助于肿瘤全切除及降低手术并发症，疗效好.
