100 patients with abnormal pain in the facial area have been examined and questioned about their symptoms and the preceding therapy. At the time of this study the patients already had a history of pain of about five years. Since no cause could be discovered for the pain, treatment was limited to symptomatic relief using injections of long-acting local anesthetics or carbamacepine. Generally, both methods resulted in a relief of the symptoms.
