Abstract:
Examination of 40 patients with malignant laryngeal and/or pharyngeal tumours shows the possibility of utilising endoscopic B-mode-sonography in ENT. The currently available devices enhance diagnostic certainty of the established radiographic methods only in cases involving oropharyngeal or certain recurrent tumours and blood vessel infiltration. The pros and cons of endoscopic ultrasonography as well as case studies are discussed.

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
