Comparison of different materials for interposition arthroplasty in treatment of temporomandibular joint ankylosis surgery: long-term follow-up in 25 cases

Abstract

A variety of interposition materials have been used to prevent recurrence after arthroplasty in treatment of temporomandibular joint ankylosis. The purpose of this retrospective study of our experience was to compare the different materials (skin, temporal muscle, homologous cartilage) used for interposition arthroplasty over a period of 22 years. A total of 25 patients (32 joints) with at least 3 years of follow-up were included. Good results were achieved in 92% of cases using total full thickness skin graft and 83% of cases using temporal muscle flap. Homologous cartilage gave poor results.
