Abstract

This chapter provides an up-to-date literature review on the relevance of CFD modeling results in clinical settings and the efforts made in the field to establish normative ranges for some CFD-derived variables. We discuss the significance of CFD-derived variables such as unilateral nasal airflow partitioning, nasal airway resistance, heat flux and wall shear stress on nasal function or symptomatology, and the strong associations established with these variables. Two important issues are discussed: (i) a need to establish meaningful representation involving combinations of different computed variables in order to accurately capture the full dynamical nature of patient-reported symptomatology; (ii) a need to develop a robust database of normative values for CFD-derived variables since typical healthy human sinonasal airway anatomies are characterized by substantial intersubject variability that confound concise description of normal airflow profile.

This relation is obtained using the definitions of airflow partitioning, nasal resistance, and the fact that the pressure drop is the same in the left and right cavities.
