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.
回顾了20例在急性创伤事件后持续存在颞下颌关节疼痛或功能障碍患者的临床、关节造影及手术 findings，并与65例不记得有创伤后急性症状发作的对照组患者的 findings 进行比较。最常见的异常情况为盘前移位（82%）、盘穿孔（65%）和旋转性盘前内侧移位（34%）。其他重要异常为关节粘连和关节囊穿孔。与对照组相比，所有这些异常在创伤关节中更常出现。发现关节造影在检测手术中发现的大多数类型异常方面具有高度准确性。据报道，关节造影在检测盘穿孔、粘连和关节囊穿孔方面比MRI更有效，这表明其作为评估创伤后颞下颌关节紊乱的成像工具仍具有重要意义。
