目的：探讨三叉神经半月节射频热凝术中电生理监测的内容和意义。方法神经导航下三叉神经半月节射频热凝术患者30例，记录术中电生理监测的数据：刺激诱发面部感觉异常的范围和阈值、刺激诱发面部运动的部位和阈值、毁损前的电阻值。毁损术前、术后分别评估视觉模拟评分（ VAS）。结果30例患者电刺激诱发面部感觉异常的阈值0．05～0．5V，平均0．21V。刺激诱发面部运动反应的阈值0．08～0．5V，平均0．27 V。毁损前电阻值283～580Ω，平均396Ω。29例患者疼痛的术后明显缓解或者消失。1例患者术后出现咬肌肌力减弱。结论完整细致的电生理监测有助于提高三叉神经半月节射频热凝术的有效率及减少手术不良反应。

Objective To assess the content and significance of electrophysiological studies during percutaneous radiofrequency ( RF) thermocoagulation of trigeminal semilunar ganglion .Methods 30 patients of RF for trigeminal neuralgia were studied for their electrophysiological monitoring data including thresholds of evoked paraesthesia and facial movement .Pre-and post-operative visual analog scores(VAS) were assessed for each patient .Results The thresholds for evoked paraesthesia and facial movement for the patients were 0.21V(range:0.05-0.5V) and 0.27V(range 0.08-0.5V), respectively .All patients received significant pain relief from the RF surgeries except one .One patient reported masseter weakness postoperatively .Conclusion Complete and thorough electrophysiological monitoring is of great significance for maximizing the effect of trigeminal semilunar ganglion RF thermocoagulation and minimizing its possible complications .
