Full-thickness skin graft interposition after temporomandibular joint ankylosis surgery. A study of 31 cases.

Recurrence is a major problem after release of temporomandibular joint ankylosis. Early physiotherapy and choice of interpositional material are important in preventing recurrence. Currently, the most used technique is gap arthroplasty associated with coronoidectomy, temporalis muscle flap interposition and reconstruction of the condylar unit with a costochondral graft. Full-thickness skin graft interposition, using the technique described by Popescu & Vasiliu, can also be used. This retrospective review of 31 patients confirms the reliability of full-thickness skin graft interposition. Results were successful in 90% of the 20 patients with follow-up longer than one year.
