Retrospective analysis of use of buccal fat pad as an interpositional graft in temporomandibular joint ankylosis: preliminary study.

摘要

PURPOSE: To evaluate the feasibility and usefulness of buccal fat pad as an interpositional graft in the treatment of temporomandibular joint (TMJ) ankylosis. MATERIALS AND METHODS: A retrospective study of 10 patients with TMJ ankylosis (9 unilateral and 1 bilateral) was performed with follow-up of 6 months to 2 years. RESULTS: In the present study, patients had a maximum interincisal opening of 32 to 41 mm (mean, 35.1 mm) at the latest follow-up. Mean deviation to the affected side on mouth opening was 1.6 mm (range, 0 to 4 mm), but chewing function was good and all the patients were satisfied. No major occlusal changes were observed and all the patients had satisfactory occlusion at the follow-up periods. No facial paresis of temporal and zygomatic branch of facial nerve was observed in any case. Periodic panoramic radiographs showed well-maintained intra-articular space because of the interposed tissue, with no signs of relapse. CONCLUSION: The findings of this study showed the short-term successful management of TMJ ankylosis using buccal fat pad as an interpositional graft.
