Figure 14a. Aneterolateral disk displacement. (a) Sagittal and (b) coronal MR images (2,800/15) of a pathologic TMJ with the jaw closed. In a, anterior displacement and deformity of the disk are noted. The arrow indicates the completely dislocated and deformed disk. For the whole sequence of images from medial to lateral, see Movie 4. In b, the lateral component of the anterolateral disk displacement can be easily identified. The disk (arrow) bulges laterally beyond the lateral condylar contour (indicated by the line). For the whole sequence of images, see Movie 5.
