Condylar position as a predictor of temporomandibular joint internal derangement.
Scout tomograms and arthrograms of 243 patients were separated and numbered. The location of the condyle within the fossa in the closed-mouth position was assessed by means of three evaluation techniques. Later, the arthrograms were interpreted and matched with the corresponding tomograms to evaluate the relationship between posterior displacement of the condyle and anterior displacement of the articular disk. The position of the disk within the fossa was found to be extremely variable whether disk position was normal or abnormal.
