ABSTRACT
The deviated nasal septum is one of the most frequent deformations of the facial skeleton. A postsurgical result of the treatment of this pathology depends on the correction of pathological changes of airflow. The structural changes of the nasal septum, intranasal formations, and their spatial correlation may be assessed using physical methods, whereas the examination of the respiratory function of the nose is complicated. The generally used frontal active rhinomanometry and an acoustic rhinometry do not answer the main question: how does the deformed nasal septum airflow change? The only way of objective assessment of the nasal respiration is the method of computational aerodynamics of the nasal cavity. It provides visualization of the airflow passing through the nasal cavity, the assessment of its main parameters as well as the modeling of surgical intervention. The objective of this literature review is to popularize the method of computational aerodynamics of the nasal septum. The authors believe that a simple explanation of the principles of the method and the demonstration of main characteristics of the airflow (rate, direction, humidity, temperature) will make its application more preferable than other diagnostic tools which will improve the efficacy of the nasal breezing improvement surgery.
