Computational Fluid Dynamics (CFD) uses highly sophisticated computer algorithms to simulate the flow of air and particles through complex 3D structures in an accurate, reproducible and scientific manner.
In recent years, researchers have begun to explore the use of CFD in the nose and airway, firstly by modelling airflow patterns, calculating changes in temperature and pressure, and measuring wall shear stress. Next, researchers studied common abnormalities, such as septal deviation, septal perforations and inferior turbinate hypertrophy. Recently, CFD has been used to model and predict the effects of surgery and therapeutic interventions.
It has become clear that CFD is a disruptive technology that is fundamentally changing our understanding of airflow in the human respiratory system and our approach to surgical procedures.
The Society for CFD of the Nose and Airway (SCONA – www.scona.org) was formed to foster knowledge, collaboration and collegiality between researchers in this exciting new field.
