Abstract
The Magnetic Resonance lmaging has been used widely to evaluate the disk position without any interruption of the TMJ structures, and the Dynamic MRI presenting computed serial imaging or the video-recorded simulation images is thought to be very
effective to evaluate the disk position under function.
This is to study the correlation between the clinical diagnosis and the findings of Dynamic MRI for the diagnosis of internal derangement of the temporomandibular joints. 30 joints (15 patients) were examined clinically, and the movement of TMJ
meniscus
was reviewed in the dynamic MRI.
@ES The comparative results are as follows :
@EN 1. All internal derangements of TMJ disk displacement without reduction were consistent with MRI findings.
2. 5 joints(50%) of disk displacements with reduction could not be confirmed by MRI findings
3. The disk displacements in MRI were found in 55% of painful joints, 50% of clicking joints, and 70% of the joints with restricted movement.
4. The reliability of MRI for the diagnosis of TMD was evaluated as 77% ; 24 of 30 joints who presented with clinical diagnosis of TMD.
5. MRI is very reliable to diagnose the disk displacement without reduction, but it is rather not so effective to diagnose the early derangement or muscle disorders.
