Middle ear functional state in case of pathological changes of nose and throat

Abstract

Objectives -to compare the functional state of middle ear in adults in case of various pathology of nasal cavity, paranasal sinuses and throat. Material and methods. In 2018-2019 period, 151 patient, aged from 16 to 70 years, was examined by acoustic impedancemetry. The patients reported the subjective satisfactory state of the acoustic organ, but had a pathology of the upper respiratory tract. Results. In the groups, there were no significant differences associated with gender. Most of the patients were of working age. In all study groups, the impaired function of the auditory tube, with various intensity, was registered, although the patients had no hearing complaints. At the same time, the acumetry and tonal threshold audiometry data indicated the normal acuity of hearing. Conclusion. Acute and chronic sinusitis was the most frequent risk factor for middle ear ventilation disorder. A quarter of patients with acute sinusitis, without otological complaints, had type B and C tympanograms. 93.7% of patients, who had undergone the surgical correction of the deviated nasal septum, did not have a middle ear ventilation disorder. Surgical intervention in the nasal cavity and oropharynx leads to a transient dysfunction of the auditory tube, but does not require special treatment due to self-recovery.
