Description

Tic douloureux is an excruciating facial pain which occurs in spasms. Apparently the cause is unknown, and the pain may be triggered by facial movement when talking or eating. After attempts to treat Hales with medications and an infraorbital alcohol block proved unsatisfactory, surgical intervention was suggested. The surgery eliminates the pain through destruction of portions of the fifth cranial nerve which serves the right side of one's face. Ideally, only two of the three divisions of the fifth cranial nerve are destroyed or severed, leaving the first or ophthalmic division functional. At the time of Hales' treatment, at least three methods of treatment were recognized: subtemporal rhizotomy, injections of hyperbaric alcohol or phenol, and radio frequency coagulation. The subtemporal rhizotomy involves a direct surgical entrance at the base of the skull exposing the fifth cranial nerve. The second and third division nerves are then selectively severed. An injection of hyperbaric alcohol or phenol into the fifth cranial nerve root, the Gasserian ganglion, causes destruction of the nerve fibers by caustic action of the injected solution. Finally, radio frequency coagulation involves a needlelike cathode which is injected into the Gasserian ganglion through an opening in the base of the skull. The nerve fibers are then selectively destroyed by the use of controlled heat developed from radio frequency current.
