Surgery for internal derangements of the temporomandibular joint.

Three hundred and twenty-seven reconstructive arthroplasties and disk repositionings have been performed during the past 6 years at Montgomery Baptist Medical Center for patients with internal derangements of the TMJ. By our evaluation, 94% are remarkably successful, 4% are marginally successful, 1% are not improved, and less than 1% are failures. On the basis of these experiences, we believe that the surgical technique of reconstructive arthroplasty and disk repositioning has a definite place in the treatment of patients with internal derangements of the TMJ.
