Change of Masseter Muscle Thickness Measured by Ultrasound After Gasserian Ganglion Radiofrequency Thermocoagulation Treatment

What this Trial Is About

Trigeminal neuralgia is a common painful disorder often seen in pain clinics. This research aims to evaluate how the thickness of the masseter muscle changes after patients receive gasserian ganglion radiofrequency thermocoagulation, a treatment used especially for cases where other therapies have not worked. The study focuses on the mandibular branch of the trigeminal nerve, which controls the masseter muscle, to understand any possible functional effects of this procedure. The treatment involves performing radiofrequency thermocoagulation under fluoroscopy guidance in a sterile operating room. A needle is positioned at the gasserian ganglion after local anesthesia and confirmed with sensory and motor tests. Then, radiofrequency heat is applied for 70 seconds at 70 degrees to affect the nerve. This study measures the thickness of the masseter muscle on both sides, both at rest and when contracted, by ultrasound before the procedure and at 1 and 3 months afterward. Participants will undergo ultrasound measurements on the day of treatment and at follow-up visits one month and three months later. The study monitors changes in masseter muscle thickness over these time points as the main outcome. The research tracks the muscle's response to the nerve ablation procedure to assess potential effects on muscle function. Participation includes regular follow-up visits to ensure consistent data collection and safety.
