OBJECTIVE: The purpose of this study was to evaluate the MR characteristics of temporomandibular joint (TMJ) disk displacement in elderly patients. METHODS: Of the MR images of 1660 TMJs in 847 patients with disk displacement who underwent MRI for suspected temporomandibular disorders, 301 TMJs in 154 patients aged more than 50 years were studied as an elderly group. These MR images of the elderly group were compared with those of a control group (1359 TMJs in 693 patients aged less than 51 years) concerning disk displacement with or without reduction, joint effusion and osteoarthrosis. RESULTS: The incidence of disk displacement with osteoarthrosis was significantly different between the elderly (41.9%) and the control (19.8%) groups (P = 0.000). Logistic multivariate regression analysis demonstrated that the osteoarthrosis was a significant variable (odds ratio = 2.94, P = 0.000). CONCLUSION: This study suggests that MR characteristics of TMJ disk displacement in elderly patients includes osteoarthrosis. |
