What Role Does Synovitis Play in Craniomandibular Dysfunction (CMD)? A 3T-MRI Study.

PURPOSE: The purpose of the present study was to investigate the degree and clinical relevance of synovitis in craniomandibular dysfunction.

MATERIALS AND

METHODS

In total, 140 temporomandibular joints were examined using a 3 T MRI scanner. Quantitative analysis of synovial enhancement was performed and interrelated with arthrosis deformans, degenerative disc disease, joint effusion, bone marrow edema and restriction of motion.

RESULTS

We found a statistically high and significant correlation between the degenerative changes as mentioned above and the intensity of synovial enhancement.

CONCLUSION

The study shows that typical MRI findings in CMD patients are often combined with signs of synovitis. Presumably joint inflammation has an effect on the clinical signs and symptoms and also the prognosis of CMD. These results should be taken into consideration when selecting treatment.

KEY POINTS: · 3T-MRI using a dedicated coil is the method of first choice in the examination of CMD syndrome.. · MR imaging allows quantification of increased synovial enhancement.. · There is a highly significant correlation between degenerative changes of the disc or cartilage and synovitis.. · Results of the study are relevant for the clinical assessment and therapy of CMD syndrome..
