The Distribution of the Velocity and Pressure Fields in the Nasal Cavity at Different Respiration Modes

摘要

Topical are the problems associated with the prediction and evaluation of the functional results of endonasal sur- gery, which, in the case of respiratory and olfactory dis- orders [1-3], are the condition of air passage through the superior nasal passage and the restoration of olfactory sensitivity. Changing the direction of the main air stream with nasal breathing leads to constant irritation o f certain sections of the muco us membrane (for example, a portion of the mu- cosa of the nasal cavity that contains olfactory receptors, the so-called olfactory zone), which will subsequently lead to cellular infiltration in this region and then to hy- pertrophy of the mucosa shell. Therefore, it is necessary to study the distribution of velocities and pressures in the nasal cavity under different respiration regimes.
