Surgery of the non-ankylosed temporomandibular joint.

Apart form the sequelae of acute trauma and ankylosis, the principal conditions affecting the temporomandibular joint for which surgery may be required are condylar hyperplasia, recurrent dislocation, internal derangement and degenerative joint disease. The indications for and techniques of surgery for these conditions are reviewed, and the results of a small survey conducted in the West Midlands are presented.
