Abstract
INTRODUCTION: Synovial chondromatosis of the temporomandibular joint (TMJ) is characterized by the formation of multiple nodules of cartilage with varying sizes due to metaplastic development of the synovial membrane. Aetiology revolves with primary lesion, and pathogenesis is still unknown with multiple factors, which includes low-grade trauma or internal derangement. This condition remains undiagnosed and leads to therapeutic challenges from clinical manifestations which are non-specific and needs various tools to diagnose with combination of radiologic and histopathological examination. MATERIALS AND METHOD: We report a case series of five cases which were diagnosed as cases of TMD of the temporomandibular joint. Diagnostic arthroscopy including lysis and lavage with Ringers lactate, hyaluronic acid was carried out. Intra-operative findings were suggestive of synovial chondromatosis. Sample taken for histopathological examination confirmed the diagnosis of synovial chondromatosis of TMJ. Postoperative status of mouth opening and pain was assessed at 15 days, one month, 3 months, 6 months and one year during the review to evaluate the success of arthroscopy of TMJ. RESULTS: All patients reported success with the modality of arthroscopy lysis and lavage at 12 months of follow-up with improvement at every follow-up visit in terms of range of motion and reduction of pain score on VAS. Hence, arthroscopy with lysis and lavage came out to be a promising alternative for open joint surgery in cases of synovial chondromatosis of the TMJ with same outcomes in relieving patients who complain of reduced maximum inter-incisal opening and pain. CONCLUSION: Thus, arthroscopic procedures can be considered an alternative and effective modality for successful management of cases of synovial chondromatosis of temporomandibular joint.
