The patient, 62-years-old woman, had a constant dull pain in the right mandible and an intermittent spontaneous burning sensation of the mouth. The pain began 6 months ago. About 5 years ago, a trauma in her right mandible which was so severe that kept her in the hospital for 2 days. This was followed by mouth opening disturbance with pain for about 2 years. However, she did not have a treatment for the temporomandibular disorder symptoms. After then, she experienced the trigeminal neuralgia characterized by an electrical pain which lasted about 30 minutes in her right face and head when touching the skin or hair. After taking a year course treatment of trigeminal neuralgia, the symptom disappeared. The pain was a constant dull pain and a intermittent burning pain which are contradictory. And the pain responded to various modalities such as physical therapy, anti-inflammatory drug, carbamazepine, and amitriptyline, among which carbamazepine was most effective. The diagnosis was clinically made as an atypical trigeminal neuralgia. The term 'atypical' is used when there is something unknown and the problem is not identified. It is thought that an atypical pain may be approached in the perspective of chronic pain, neuropathic pain, and myofascial pain, the mchanisms of which are poorly understood. As the knowledge of pain physiology improves, there needs to be modification and re-evaluation. Pain disorders must be classified on the basis of an understanding of the underlying mechanism and etiology.
