CFD MODELING OF NASAL AIRFLOW IN THE PATIENTS WITH A NASAL SEPTUM DEVIATION
Relevance: nasal septum deviation is a highly common pathology of the nasal cavity. The emergence of a new method of CFD modeling has made it possible to study the biophysical processes occurring in the pathological nasal cavities.
The purpose of this experiment was to study the velocity and partial pressure of the air flow inside nasal cavity for the different nasal septum deviation types.
Materials and methods: the study used CT scans of 7 patients. Using special software algorithms for CFD modeling, 3D nasal models and virtual air flows were obtained from these images. We examined the mean nasal flow velocity and partial pressure for each type of nasal septum deviation.
Results: the average flow velocity for the 4th and 7th types of nasal septum deviations was 7.3 and 7.6 m / s, and the partial pressure was -10.2 and -9.8 Pa, respectively, which was much higher than the data for other deviation types.
Conclusion: The nasal septum deviation type affects the flow velocity and partial pressure in the nasal cavity.
