Introduction: MRI is regarded as superior to other imaging techniques in evaluating temporomandibular
disorders (TMDs), since MRI can provide positional information about disc, volume
of synovial fluid, and qualitative data about the status of retrodiscal tissues and surrounding
muscular tissue.
Objective: The aim of this study was to evaluate disc position, degenerative changes of condylar
head, intracapsular effusion and signal intensity of retrodiscal tissues in patients with
TMDs using with MRI.
Material and Method: 32 patients with TMDs were examined with MRI. Spurring, flattening and
erosion along condylar surface, glenoid fossa or articular eminence were classified as degenerative
changes on the MRIs. Intracapsular effusion was evaluated with T2-weighted images as
increased signal. The signal intensity of TMJ disc was also assessed.
Results: The disc position was normal in 9.3 % and anteriorly displaced in 37.5 % of the TMJs.
Intracapsular effusion was observed in 18.75 %. There was a significant correlation between
displacement of the disc and the hyperintense signal (p < 0.01). The relationship of intracapsular
effusion with disc displacement, TMJ pain and the type of disc displacement were
statistically significant (p
