Análise por meio de ressonância magnética em pacientes sintomáticos da relação entre as alterações ósseas da articulação temporomandibular e derrame articular em função do posicionamento do disco articular / Analysis by magnetic resonance imaging in symptomatic patients of the relationship between bone changes of the temporomandibular joint and joint effusion related to articular disc position

RESUMO

The temporomandibular joint (TMJ) is considered the most complex articulation of the human body. Like other joints of the musculoskeletal system it can be affected by the same diseases and disorders, such as disc displacement, degenerative joint disease (osteoarthritis - OA), inflammatory arthritis and synovitis. Based on reports obtained by the analysis of images in standard sagittal TMJs of symptomatic patients referred for magnetic resonance exam were evaluated the presence of bone changes in the condyle, articular eminence and glenoid fossa, and the presence of joint effusion arising from the positioning of the disc. The sample consisted of 148 TMJs in 74 symptomatic patients. The bone changes occurred more frequently in the condyles, especially the appearance of osteophytes and erosions in cases of disc displacement without reduction. The results of statistical tests revealed that the bone changes of the condyle type erosion and osteophyte and anterior articular eminence, as well as joint effusion are associated with the disc position.
