[The influence of the nasal septum tubercle on certain aerodynamic characteristics].

The objective of the present work was to investigate the influence of the tubercle of the nasal septum thickening on the localization of the regions of precipitation of aerosol particles in the nasal cavity under the experimental conditions. The experiment was conducted using the newly developed 3D stereolithographic model of the nasal cavity. The study has demonstrated that the tubercle of the nasal septum thickening is an aerodynamically-conditioned normal anatomical structure, and its absence deteriorates the aerodynamic characteristics of the airflow through the nasal cavity.
