Abstract：
OBJECTIVE: Radiofrequency thermocoagulation (RFT) for refractory trigeminal neuralgia is usually performed in awake patients to localize the involved trigeminal branches. It is often a painful experience. Here, we present RFT under neuromonitoring guidance and general anesthesia.
METHODS: Stimulation of trigeminal branches at the foramen ovale with the tip of the RFT cannula is performed under short general anesthesia. Antidromic sensory-evoked potentials (aSEP) are recorded from the 3 trigeminal branches. The cannula is repositioned until the desired branch can be stimulated and lesioned.
CONCLUSIONS: aSEP enable accurate localization of involved trigeminal branches during RFT and allow performing the procedure under general anesthesia.

摘要：
目的：难治性三叉神经痛的射频热凝（RFT）通常在清醒患者中进行，以定位受累的三叉神经分支。这往往是一种痛苦的经历。这里,我们在神经监护指导和全身麻醉下进行RFT。
方法：用RFT套管的尖端刺激卵圆孔的三叉神经分支是在短暂的全身麻醉下进行的。从3个三叉神经分支记录了反行感觉诱发电位（aSEP）。套管被重新定位,直到期望的分支可以被刺激和损伤。
结论：aSEP能够在RFT期间准确定位受累三叉神经分支，并允许在全身麻醉下进行手术。
