Endoral ultrasound was introduced for imaging of T1 and T2 tumors of the anterior third of the tongue and the floor of the mouth in 1988. Using this method, 100 patients with diseases of the oral cavity and the oropharynx were examined, and the findings were compared with those of transcutaneous ultrasound, CT and MRI. Endoral ultrasound provided valuable additional information in tumors of the tongue base and the middle and dorsal third of the tongue. Tumors of the tonsil were demonstrated very well. MRI proved to be superior for imaging of large lesions. CT was of less value in diagnostic imaging of the oral cavity and the oropharynx due to low soft tissue contrast.
