Determination of nasal breathing disorders according to computer tomography

The most important factor that determines the normal functional state of the nasal mucosa is that which passes through it during inhalation and exhalation air flow, which, entering the nasal cavity, due to the active expansion of the chest feels resistance from the surrounding structures. This factor is influenced by an indicator such as air flow resistance, with 54% of the total resistance of the respiratory system to the upper respiratory tract, including 46% of the resistance of the nasal cavity. In addition, it is necessary to study the aerodynamic laws that play an important role in the regulation of the degree of nasal resistance. Nasal resistance can be affected by a variety of external factors and pathological processes in the nasal mucosa: cold air inhalation, hyperventilation, allergy and inflammation, alcohol abuse. Thus, the blood supply in the cavernous venous plexuses promotes swelling of the nasal membranes, an increase in their size, and narrowing of the lumen of the nasal valve to completely block the nasal cavity, causing changes in normal function. Such air flow supports clearly require an objective study to overcome it. Given that the objective assessment of nasal resistance is extremely difficult, it is necessary to create additional diagnostic methods, tools and criteria based on data from a complex of diagnostic measures, such as computed tomography, endoscopy, rhinomanometry.
