Arthrographic evaluation of the internal derangement of temporomandibular joint.

From a functional point of view, the temporomandibular joint(TMJ) is one of the most important joints in the body. Optimal radiographic visualization is becoming increasingly important to medical and dental specialists as abnormal TMJ derangements are becoming better understood. Because the most common TMJ arthropathy is the internal derangement of TMJ, arthrography of the temporomandibular joint is widely performed in clinical practice. From January 1986 to December 1990, twenty temporomandibular joint arthrographies were performed in patients with symptoms of pain, clicking and dysfunction. We report our findings on these twenty patients who were examined by arthrography, which was conducted due to internal derangements related to meniscal dysfunction.
