OBJECTIVES: To test the hypothesis that flattening of the slope of the articular eminence occurs with progressive internal derangement (ID) of the TMJ. METHODS: MR images of 170 TMJs in 130 patients with proven disk displacement were studied. The correlation between the prevalence of a flattened articular eminence and radiological stage of ID was analysed. RESULTS: The prevalence of a flattened articular eminence was significantly higher in the joints with advanced ID (Mann-Whitney's U-test, P < 0.05). CONCLUSIONS: It appears that a flattening of the slope of the articular eminence occurs as a result of remodeling or degenerative changes secondary to ID.
