Abstract
Abstract Background: The use of magnetic resonance imaging (MRI) in the assessment of temporomandibular joint (TMJ) injuries has been a mainstay. Since it can non-invasively showing major regional anatomic structures and revealing the presence of joint effusion and bone marrow signal-intensity abnormalities. Aim of Study: To elucidate the role of MRI in the diagnosis of TMJ injuries and for which extent MRI is able to detect its abnormalities. Patients and Methods: A total of 43 patients with TMJ injuries were included in the study. A 1.5 tesla MRI machine is used to assess the TMJs. The position of the disc, its configuration, the presence or absence of joint effusion, osteoarthritis, and the morphology of the mandibular condyle were all evaluated. Results: The clinical symptoms of the patients there were higher of symptoms in sensation of pain (86%); followed by limited mouth opening (44.2%). The patients anterior disc dislocation with reduction was higher value was found in patients' injuries of temporomandibular joint 17 patients (39.5%) with p-value
