Temporo mandibular joint disease in ankylosing spondylitis

Abstract

The occurrence of temporo mandibular joint (TMJ) disease in ankylosing spondylitis is not widely recognized and its incidence is disputed. 79 Patients attending 2 routine rheumatology clinics were therefore examined by a dental surgeon, and 9 (11.5%) were considered to have specific TMJ involvement. These patients were older than the remainder, and had more extensive spinal and peripheral joint disease. Symptoms were mild, and the predominant clinical feature was restricted mouth opening, which could present considerable difficulties during emergency anaesthesia. Bilateral condylectomy was undertaken in one patient with some benefit.
