Figure 4

Images demonstrating anterior displacement of the disc in the sagittal plane in the (a) closed-mouth position with MR, (b) disc recapture in the open-mouth position with MR, (c) closed-mouth position with US, and (d) recapture in the open-mouth position with US. The disc retains normal morphology. A focal annotated view was provided to aid visualization with the articular disc outlined with a dotted contour; condyle = “c”; eminence = “e”; anterior = “ant.”
