Abstract　： [Introduction] In the past decade, the arthroscopy of the temporomandibular joint (TMJ) has altered the concept regarding TMJ pathology and diagnosis of the internal derangement and arthrosis. This procedure has also successfully addressed the position as an alternative surgical intervention in the treatment of TMJ internal derangement in replacing with open arthrotomy. This review article describes the current advances of the basic investigations in relation to arthroscopic diagnostic examination, and discuss the clinical usefulness of arthroscopic surgery. [Basic Investigation in the Laboratory and Pathology in Relation to Diagnostic Arthroscopy] Merill and his colleagues described that there was a positive correlation between arthroscopic inspected synovitis and a histologic report of inflamed synovial tissue. Quinn and Bazan identified a significant level of prostaglandin E2 and leukotriene B4 as the chemical pain mediator in the synovial fluid of painful, dysfunctional TMJs, in which the arthroscopic index of synovitis was well correlated to the concentrations of the mediators. Therefore, it is apparently recognized that the synovitis is a barometer of the TMJ arthralgia.
