Применение широкополосной тимпанометрии для оценки состояния структур среднего уха у пациентов с хроническим риносинуситом

Abstract

It is well known that chronic rhinosinusitis can cause changes in the auditory analyzer. According to domestic and foreign literature data, the prevalence of otological symptoms in patients with chronic rhinosinusitis occurs from 15 to 42% of cases. In this category of patients, both sensorineural, conductive, and mixed forms of hearing loss may occur. Hearing loss in rhinosinusitis may be associated with several factors. First, the inflammatory process in the nasal cavity and paranasal sinuses leads to impaired circulation of exudate, stagnation of mucus, and, as a result, to an increase in intratympanic pressure. Second, inflammatory changes in the mucous membrane of the nasopharynx and auditory tube lead to a violation of the drainage function of the latter. Despite the obvious anatomical and physiological relationship between inflammatory lesions of the nasal cavity and paranasal sinuses and damage to the structures of the middle ear, the condition of the structures of the middle ear against the background of chronic rhinosinusitis is still insufficiently studied, especially in the preoperative and early and long-term postoperative periods, after rhinosurgery. The expansion of the range of modern diagnostic capabilities allows you to look at this problem differently and solve it.
