PurposeTo demonstrate the feasibility to acquire high-resolution sagittal ultrasound images of the temporomandibular joint (TMJ).Patients and MethodsThe investigators employed commercially available ultrasound (U/S) probes to assess the TMJ via a transoral soft tissue window in order to acquire sagittal images. Magnetic resonance (MR) imaging and clinical correlation were compared to the U/S findings by the consensus assessment of two of the senior investigators.ResultsThe sample was composed of 10 TMJ's (6 subjects) with an age range of 34-71 years old, and with a male:female ratio of 3:1. The condyle and subcondylar surface were visible in 10/10 (100%) joints; the disc in 7/10 (70%) of joints, and the pterygoid muscles in 6/10 (60%) of joints. In the 5 joints with MR correlation, disc position and configuration were confirmed in all cases.ConclusionWe demonstrate the first sagittal transoral sonograms of the TMJ disc and associated joint components.
