Overview
Panoramic TMJ projections provide bilateral overview of condylar position and joint space in a single acquisition. They are useful for screening degenerative change and gross asymmetry. Proper patient positioning ensures comparable bilateral images.
Technique
Use panoramic equipment with TMJ specific settings and instruct the patient to bite in centric occlusion. Center to the TMJ region and ensure head stabilization during rotation. Remove metallic objects that may cause artifacts.
Clinical Indications
Panoramic TMJ imaging is indicated for screening degenerative disease trauma and gross asymmetry. It complements dedicated TMJ open closed views and MRI for soft tissue evaluation. Use as part of dental and maxillofacial assessment.
Image Assessment
Compare condylar morphology joint space and symmetry between sides. Look for erosive change osteophytes and gross displacement. Recommend MRI for disc and soft tissue pathology when indicated.
