Computational Fluid Dynamics in the assessment of nasal obstruction in children.

In the 5 children, the results of CFD were concordant with clinical complaints and examination. In 3 children, AAR and CFD were concordant. In one patient, CFD corrected the results of AAR. In one patient, AAR was not feasible, unlike CFD, which contributed to diagnosis. This study highlighted the feasibility of CFD in children and that it can support or refute diagnosis of nasal obstruction with good reliability. These results indicate that CFD modeling could be widely used for functional exploration in pediatric rhinology.
