Objective: The objective of this study was to compare findings from ultrasonography imaging (USI) of the temporomandibular joint (TMJ) with those from magnetic resonance imaging (MRI) and cone-beam computerized tomography (CBCT). Methods: A total of 102 patients were included in this study. USI, MRI, and CBCT were performed in the TMJ area for all patients. Results: USI showed 100% sensitivity (Se), 82.76% specificity (Sp), 93.15% positive predictive value (PPV), 100% negative predictive value (NPV) and 94.85% accuracy relative to MRI for identifying anterior disc displacement (ADD), while the Se, Sp, PPV, NPV, and accuracy were 100% for identifying joint effusion, relative to MRI. Moreover, USI showed a high agreement with CBCT, which had 98.08% Se, 94% Sp, 94.44% PPV, 97.92% NPV and 96.08% accuracy for identifying condylar irregularities, while MRI showed a 100% Se, 56.86% Sp, 69.86% PPV, 100% NPV, and 78.43% accuracy for detecting condylar irregularities, relative to CBCT. Conclusions: High-resolution USI is a useful diagnostic method for detecting TMJ pathologies; USI can supplement clinical evaluations for patients with temporomandibular joint disorders (TMDs), and this imaging modality can be used as a diagnostic tool to identify internal derangement of the TMJ.
