Overview
Introduction: The pattern of the nasal airflow is crucial for normal nasal breathing as well as it can be a pathophysiological underlay of nasal symptoms (nasal obstruction, crusting etc). It is difficult to define one physiological airflow pattern because subjective symptoms of patients do not correlate with objective findings quite often. Nowadays, the computational fluid dynamics (CFD) is dominant way how to simulate and study nasal airflow.
Methods: For nasal airflow simulation 3D model of nasal cavity was created according to CT scans of nasal cavity (patient had no problems with nasal breathing). The 3D model was created with the cooperation with Technical University of Ostrava.
Results: Our first experience with CFD showed that there is a different airflow pattern between right and left nasal cavity. Major part of airflow was detected in inferior and inferior part of common meatus and also in the middle and in the middle part of common nasal meatus. These results support studies that declare differences in nasal aerodynamics among healthy adults.
Conclusion: CFD has a potential to be used in clinical practice especially in functional rhinosurgery.
