Abstract:Objective: To summarize the experience of selective percutaneous radiofrequency thermocoagulation which was performed on 1936 cases with trigeminal neuralgia. Methods: Supraorbital foramen, infraorbital foramen and oval foramen radiofrequency thermocoagulation were performed on 1936 cases of trigeminal neuralgia. X ray, 3D CT and navigation oval foramen locations were used in 22, 19 and 4 patients respectively on intractable trigeminal neuralgia in order that the direction and position could be defined. Results: Pain has been eliminated in 1528 cases, alleviated in 336 cases. No changes were observed in 72 cases. No serious complications occurred in all of the patients. The effective rate is 96.3%. Conclusion: Selective percutaneous radiofrequency thermocoagulation is an effective way for the treatment of trigeminal neuralgia. X ray, 3D CT and navigation oval foramen locations can increase the successful rate of puncture, thus enhancing the safety and reducing the incidence rate of complications.
