Abstract
✓ The authors describe surgical and anesthetic techniques for the treatment of trigeminal neuralgia by radiofrequency coagulation. Using radiographic landmarks derived from a stereotaxic study of 54 cadaver skulls, they delineate lateral and anteroposterior guidelines which aid in the percutaneous penetration of the foramen ovale. Controlled lesions can be made selectively in any division of the trigeminal nerve. The procedure has been effective in abolishing pain usually with preservation of touch sensation in the face. The percutaneous operation has the added advantage of a short hospitalization, usually 2 days. Of the 65 patients treated, only one still has the pain of trigeminal neuralgia. In six instances the procedure had to be repeated because insufficient sensory deficit was produced by the initial lesion. Three patients have developed anesthesia dolorosa; however, none has developed facial paralysis.
