Abstract
92 sonographic examinations performed in 62 patients were evaluated to determine the possible application of sonography in the diagnosis and follow-up of malignant tumours of the tongue. Squamous cell carcinomas were by far dominant and proved to be hypoechoic, mainly inhomogeneous and ill-defined masses. In most cases, they ranged between 2 and 4 cm. in diameter. In 50% of the lesions an infiltration of the pharynx wall was confirmed, and exulcerations were correctly detected by sonography in 75%. In preoperative determination of the size of the tumour, sonography correctly detected the size in 93% of the cases and was thus markedly superior to the clinical palpatory examination, which determined a mere 43% correctly. Sonography should be included in the pretherapeutic staging of tumours of the tongue to objectify the clinical findings. It is also adequate to document tumour behaviour during radiation.
