Abstract：Objective To explore the clinical effect of radiofrequency thermocoagulation guided by frameless stereotaxy for primary trigeminal neuralgia. Methods Under the guidance of frameless stereotaxy, the gasserian ganglion was punctured through foramen ovale via anterior approach in 30 patients with primary trigeminal neuralgia. The targets were verified by intraoperative electrical stimulation and treated by radiofrequency thermocoagulation. Results One-time puncture success rate was 100%. During the follow-up period of 6 to 36 months, the trigeminal neuralgia disappeared in 29 patients and was relieved in 1 patient. The complications included facial numbness in 8 patients and masticatory force weakness in 1, and there were no other serious postoperative complications. Conclusion Radiofrequency thermocoagulation under the guidance of frameless stereotaxy is safe and effective for primary trigeminal neuralgia, of a high success rate of one-time puncture and can decrease the complications caused by blind puncture.
