One hundred fifty eight joints (79 patients) with temporomandibular disorders were studied with MRI and tomography in order to clarify the relationship between the bony changes of the condylar head and the displacement of the disk of the temporomandibular joint.The bony changes of the condylar heads were seen in 77.8% of the joints with anterior disk displacement. All cases of erosion, osteophyte and deformity (3 cases, 9 cases, and 5 cases, respectively) had anterior disk displacement without reduction.From these results, it is suggested that the bony changes of the condylar head are closely related to anterior disk displacement (p<0.001) and should be interpreted as signs of internal derangemet of the joint.
