摘　　要：目的 探讨应用Stryker LEIBNGER神经导航指导锁孔显微手术切除重要功能区小病灶的手术效果和精确性以及提高手术疗效及降低并发症的作用。方法 32例患者应用神经导航辅助锁孔显微手术切除重要功能区小病灶。病变直径0．5～1．8cm。对其注册精度、术中导航精度、手术效果进行分析。结果 神经导航系统平均注册误差0．5mm。术中脑移位的平均水平误差0．8mm，平均垂直误差0．7mm。所有病例均顺利寻找到病灶并作显微镜下全切除。骨窗面积平均为2．5cm×2．5cm。术后神经系统功能保留良好。无严重并发症。无手术死亡。结论 神经导航引导下采用锁孔开颅显微手术切除脑重要功能区小病灶具有定位精确，动态示踪和实时导航，侵袭性小，安全、可靠等特点。Objective To evaluate the operative effect and accuracy about the Stryker LEIBNGER neuronavigation-assisted key-hole microsurgery to resect the mini-lesions in the eloquent area. Methods Neuronavigation-assisted key-hole microsurgery to resect mini-lesions in the eloquent area were applied on 32 patients. The diameter range of lesion was from 0. 5cm to 1. 8 cm. It was analyzed about their registration accuracy, intraoperative accuracy and operation effect. Results Neuronavigation＇s average registration error was 0.5mm. In the operation, brain shift of average horizontal error was 0.8mm, and average vertical error was 0. 7mm. All focuses were successfully located and totally resected by using neuronavigation and microscope. The average area of the bony window was 2. 5cm× 2. 5cm. The post-operative neurological function remained well with no serious complication or mortality. Conclusion By using neuronavigation, key-hole microsurgery to resect the mini-lesions in the eloquent area bears many features such as localization accuracy,dynamic state to hint trace, real-time navigation, little infestation, safety and reliability,and so on.
