摘要
目的 探讨神经导航系统辅助下卵圆孔定位穿刺在三又神经半月神经节射频热凝术中的临床应用。方法 术前颅脑CT薄层扫描获取影像资料，在Brain—Lab导航工作站进行颅底重建，观察并测量卵圆孔相关数据；应用计划系统勾画卵圆孔作为靶点，在导航棒引导下卵圆孔穿刺。结果 共施行21例，均一次性穿刺成功，术中阻抗405～710Ω，平均505Ω，感觉刺激平均值0．52V．运动刺激平均值0．85V。所有病例术后均痛觉消失，触觉保留。将获得卵圆孔相关数据进行统计推断。结论 卵圆孔孔径影像学测量均值与文献尸头测量均值比较无统计学差异，左右侧卵圆孔孔径大小无统计学差异；射频热凝术治疗三又神经痛效果的关键是卵圆孔的准确定位，在导航棒辅助下，卵圆孔穿刺准确率为100％。
Objective To explore the value of navigation foramen ovale localization at radio frequency thermocoagulation of trigeminal semilunar ganglion. Methods Preoperation, We get skull CT laminae scan to obtain image material, to reconstruct basi of the cranium at Brain-Lab workstation,to observe and measure foramen ovale correlated data. Applicating BrainLab workstation to draw the outline of foramen ovale as target,then we punctured by image navigating instrument. Results We performed 21 cases, all successfully punctured by one shot. In operating, the reluctance is 405～710Ω, which mean value is 505Ω; The mean value of sensory irritation is 0. 52V,which of motion stimulation is 0. 85V. All cases analgesia after operation with sense of touch reservation. We followed foramen ovale datas by statistical description and deduction. Conclusion There is no statistics difference in mean valure of foramen ovale between iconography measurement and cadaver head measurement. Foramen ovale bore of both side haven＇t statistics difference;Exact localtion of foramen ovale is key to radio frequency thermocoagulation, assisted by navigation, the accuracy rate of puncturing is 100%.
