Total Alloplastic Temporomandibular Joint Reconstruction for Management of TMJ Ankylosis.

Introduction: Temporomandibular joint (TMJ) ankylosis involves the fusion of the mandibular condyle to the glenoid fossa, the skull base. The dilemma with regards to treatment planning whether distraction is done before gap arthroplasty or as a simultaneous procedure or after gap arthroplasty is still a controversy. In an attempt to carry out both the procedures simultaneously there is loss of vector control of the distal segment and the risk of pseudoarthrosis at the osteotomy site.
