title: Arthrographic imaging of post-traumatic temporomandibular joint disorders.
abstract: Clinical, arthrographic and surgical findings in 20 patients who showed persisting TMJ-pain or dysfunction after an acute traumatic event were reviewed and compared to findings in a control group of 65 patients who did not remember an acute post-traumatic onset of symptoms. Anterior disk displacement (82%), disk perforation (65%) and rotational anteromedial disk displacement (34%) were the most common abnormalities encountered. Other important abnormalities were joint adhesions and capsule perforation. When compared with the control group, all these abnormalities occurred more often in traumatised joints. Arthrography was found to be highly accurate in detecting most types of abnormalities found during surgery. Arthrography is reported to be more effective than MRI in detecting disk perforations, adhesions and capsule perforations, which points to its continuing importance as an imaging tool for evaluating post-traumatic temporomandibular joint disorders.
