Optimization of the nasal valve pathology diagnostics

Abstract

The authors improved diagnostics of the external nasal valve dysfunction by means of spectral acoustic analysis of audio signals, using ≪Мulti Speech≫ program. 102 patients have been examined according to this method: 70 people without the external nasal valve pathology, 32 people with of the external nasal valve failure. The results of the study: based on the study of registration of the nasal breathing duration, it was found that in the patients with the external nasal valve failure, causing its inspiratory collapse, the inhalation duration during Сottle’s Test increased by 17,9%, and during the forced respiration it decreased by 79,8% (р < 0.05). In patients with cicatricial deformation of the nasal vestibule of the nose the inhalation duration during Сottle’s Test did not change, and during the forced respiration it decreased by 70,1% (р < 0.05).
