- <p><strong><span lang="EN-US">Abstract</span></strong></p> <p><strong><span lang="X-NONE">Background:</span></strong><span lang="X-NONE"> Temporomandibular joint (TMJ) disorders are prevalent, affecting up to 28% of the population, with internal derangement being the most common etiology. Magnetic resonance imaging (MRI) is a non-invasive, high-resolution imaging modality critical for evaluating TMJ pathologies due to its superior soft tissue contrast and ability to visualize disc displacement, joint effusion, and degenerative changes.</span></p> <p><strong><span lang="X-NONE">Objective:</span></strong><span lang="X-NONE"> This study aims to assess the role of 3 Tesla MRI in diagnosing TMJ pathologies, focusing on its diagnostic accuracy in detecting abnormalities such as disc displacement and joint effusion, and its correlation with clinical findings to enhance treatment planning.</span></p> <p><strong><span lang="X-NONE">Methods:</span></strong><span lang="X-NONE"> An observational descriptive study was conducted at a tertiary care hospital, involving 98 patients (196 joints) with suspected TMJ dysfunction. Patients underwent 3T MRI scans using T1-weighted, T2-weighted, and proton-density sequences in multiple planes. Parameters assessed included disc position, degree of displacement, disc reduction, disc shape, joint effusion, degenerative changes, and condylar translation. Data were analyzed using SPSS, with statistical significance determined by Pearson’s Chi-Square test (P<0.05). Diagnostic accuracy was compared to arthroscopy.</span></p> <p><strong><span lang="X-NONE">Results:</span></strong><span lang="X-NONE"> Abnormal MRI findings were observed in 54.5% of joints, with anterior disc displacement in 51% (20.9% complete, 30.1% partial). Disc reduction occurred in 69.8% of joints, and joint effusion was prevalent in 92.8%. Degenerative changes were noted in 10.2% of joints, and osteoarthritis was diagnosed in 2%. MRI demonstrated a sensitivity of 95%, specificity of 88%, and accuracy of 94% compared to arthroscopy. Female predominance (71.4%) and a younger age distribution (87.6% aged 18-45 years) were significant (P<0.05).</span></p> <p><strong><span lang="X-NONE">Conclusion:</span></strong><span lang="X-NONE"> 3T MRI is a highly effective diagnostic tool for TMJ pathologies, offering excellent sensitivity and specificity in detecting disc displacement and joint effusion. Its ability to correlate imaging findings with clinical symptoms supports its role in guiding treatment and improving patient outcomes.</span></p>
