Over the past decades, the authors have noted an increase in the incidence of exudative otitis media (EOM), and it is 15-17% among all ear diseases. It is known from the scientific literature that in patients with EOM, attention should be paid to the state of the pharyngeal mouth of the auditory tubes and anatomical structures bordering on this area, since it is their pathological changes that most often lead to the development of the disease. Obstructive dysfunction is the most common cause of EOM. It can be caused by a mechanical violation of the patency of the auditory tube due to benign and malignant neoplasms of the nose, paranasal sinuses and nasopharynx.
