Temporalis Myofascial Flap Interpositional Arthroplasty with Bilateral Coronoidectomy for Management of Unilateral TMJ Ankylosis: A Retrospective Study
Journal Title: Journal of Medical Science And clinical Research - Year 2018, Vol 6, Issue 8
Abstract
Introduction: Temporomandibular joint (TMJ) ankylosis is an extremely disabling condition seen commonly. Surgical management of TMJ ankylosis needs careful planning and thorough evaluation to achieve good results. Aims & Objectives: This study was conducted with the aim to evaluate the role of interpositional arthroplasty using temporalis myofascial flap with bilateral coronoidectomy in achieving maximum interincisal mouth opening (MIO) in unilateral TMJ ankylosis. Materials and Methods: A total of 16 patients with unilateral TMJ ankylosis were included in the study. The patients underwent interpositional arthroplasty using temporalis myofscial flap along with bilateral coronoidectomy under general anaesthesia. Pre and post operative MIO’s were measured. Results: The mean MIO after osteoarthrectomy and ipsilateral coronoidectomy was 33.5mm. The mean MIO after bilateral coronoidectomy was 42.1mm. The mean increase in MIO after bilateral coronoidectomy was 8.75mm. There were no recurrences in any patient in this study. Conclusion: The present study shows that temporalis myofascial flap is a good choice for interpositional arthroplasty for management of TMJ ankylosis. Bilateral coronoidectomy in unilateral TMJ ankylosis gives better intraoperative mouth opening which was maintained in the long term
