| The article is devoted to the study of the negative influence of air flow on the mucous membrane of the nasal cavity. in the section the basic provisions of the aerodynamics of the nasal cavity are considered, the main characteristics of the laminar boundary layer in the nasal cavity are determined. it is determined that the thickness of the boundary layer strongly depends on the mode of respiration, with forced breathing, the difference in the thickness of the boundary layer between the norm and in the narrowing of the nasal passage significantly decreases. with a quiet breath, the thickness of the boundary layer will essentially depend on the equivalent diameter of the nasal canal. thus, with the growth of the equivalent diameter of the nasal passages, the thickness of the boundary layer increases significantly, which is especially noticeable when forced respiration. therefore, the negative effect of air flow will be manifested, above all, with increased costs and narrowing of the nasal cavity and depend on the heterogeneity of the mucous membrane of the nasal cavity, which with forced breathing is more likely to go beyond the laminar boundary layer. in calculating the parameters of the boundary layer, it is necessary to specify the parameters of air flow, obtained as a result of computer olfactometry or physiological data for the corresponding breathing regimes. with the increase of respiration and the corresponding reduction of the thickness of the boundary layer of the air stream, the risk of negative influence of turbulent air flow on the mucous membrane of the nasal cavity increases. the use of this method makes it possible at the stages of diagnosis and surgical planning to quantify the effect of the negative influence of air flow on the mucous membrane of the nasal cavity, which is associated with turbulent drying and determine the areas that are subject to surgical correction by the proposed criterion. |
