title: Denervation of the painful temporomandibular joint.
abstract: The successful management of temporomandibular joint (TMJ) pain remains elusive. Often the initial relief of pain is complicated by recurrence of the symptoms. This time frame suggests that the pain may be related to neuromas of the nerves that innervate the TMJ. In 2003, an anatomic description of the innervation of the TMJ suggested that denervation of this joint might be the appropriate treatment for pain resistant to traditional forms of therapy. In January, 2005, this approach was used to treat recalcitrant left TMJ pain in a 21-year-old woman with congenital hearing loss who had recurrent dislocations of her TMJ articular disc. She previously had two arthroscopic surgeries and one open attempt to treat her TMJ pain. The last failed TMJ surgery created a painful neuroma that prevented her from wearing her hearing aid. A medial and lateral denervation of the TMJ joint was done. The successful results of this surgery are presented at one-year follow-up. The technical considerations of this approach and risk to the facial nerve are discussed.
