Correlation between nasal airflow characteristics and clinical relevance of nasal septal deviation to nasal airway obstruction.

Highlights: [•] We create 6 anatomically accurate models of nasal cavity with Septal Deviation (SD). [•] These models are of 3 symptomatic and 3 asymptomatic Nasal Airway Obstruction (NAO). [•] We investigated airflow characteristics in 6 asymmetric nasal cavity models by CFD. [•] We correlate airflow characteristics with the clinical relevance of SD to NAO. [•] There exist plausible correlations between airflow properties with symptoms of NAO. [Copyright &y& Elsevier]
