Try radiofrequency thermal lesioning. Radiofrequency thermal lesioning, also known as RF ablation, is an outpatient procedure consisting of coagulating nerve fibers with an electrode to desensitize areas where pain is experienced.
- During the procedure, a needle with an electrode is inserted into the trigeminal nerve.
- Once the area of nerve that causes the pain is located, your doctor sends small electrical pulses through the electrode to damage the nerve fibers, resulting in numbing of the site.
- In about 50% of the patients, the symptoms reoccur three to four years following the procedure.
