The authors performed direct sagittal computed tomography (CT) on 4 cadaver temporomandibular joints (TMJ) and examined 51 TMJs in 47 patients clinically. The results were correlated with cadaver anatomical sections and clinical arthrographic findings. A fat plane between the bellies of the lateral pterygoid muscles, termed the "lateral pterygoid fat pad," served as the anatomical basis for detection of internal derangements by CT. CT was 94% accurate in detecting meniscal derangements and 96% accurate in detecting degenerative arthritis. The authors suggest that CT rather than arthrography be employed as the primary TMJ imaging modality when internal derangement or arthritis is suspected.
作者对4具尸体的颞下颌关节（TMJ）进行了直接矢状面计算机断层扫描（CT），并对47例患者的51个TMJ进行了临床检查。将结果与尸体解剖切片及临床关节造影结果进行了对比。翼外肌肌腹之间的一个脂肪平面，称为“翼外肌脂肪垫”，作为CT检测关节内紊乱的解剖学基础。CT检测半月板紊乱的准确率为94%，检测退行性关节炎的准确率为96%。作者建议，当怀疑有关节内紊乱或关节炎时，应将CT而非关节造影作为主要的TMJ成像方式。
