Figure 1.

Schematic imaging features of osseous changes in the mandibular condyle (A-D) and fossa (E-G) for evaluation. Osteophyte (A): marginal bony deposition and bone outgrowth on the condyle are marked with an asterisk. Erosion: loss and irregular surface of cortical bone of the condyle (B) and fossa (E) are marked with arrows. Flattening: the bony contour becomes flattened on the articular surface of condyle (C) and fossa (F), as marked with arrows. Sclerosis: the increased cortical bone area extending into the bone marrow of the condyle (D) and fossa (G) is marked with an asterisk.
