To introduce our device and procedure of electromagnetic navigation (EMN)-guided radiofrequency thermocoagulation (RFT) in patients with trigeminal neuralgia (TN).
The EMN system mainly consists of an electromagnetic localizer, a thermoplastic facial mask with fiducial markers, and navigation software. A new surgical interface in which the foramen ovale (FO) and the trigeminal ganglion (TG) were integrated was used. It was applied in three patients with TN.
FO was successfully and accurately cannulated on the first attempt by using EMN guidance. During the follow-up period, pain did not reoccur, and appropriate trigeminal sensory paresthesia was elicited. There were no surgery-related complications.
The EMN system is effective and highly accurate for RFT in patients with primary TN. Our modification of the registration system and surgical interface could make the RFT process more simple and accurate.
介绍我们用于三叉神经痛（TN）患者的电磁导航（EMN）引导下射频热凝术（RFT）的设备及操作方法。
EMN系统主要由电磁定位仪、带有基准标记的热塑性面罩和导航软件组成。使用了一种新的手术界面，其中整合了卵圆孔（FO）和三叉神经节（TG）。该方法应用于3例TN患者。
在EMN引导下首次尝试即成功且准确地穿刺到FO。随访期间，疼痛未复发，且引出了适当的三叉神经感觉异常。无手术相关并发症。
EMN系统对原发性TN患者的RFT有效且高度准确。我们对注册系统和手术界面的改进可使RFT过程更简单、准确。
