Abstract:
Estimation of nasal airflow, flow asymmetry and nasal valve stiffness was performed using anterior rhinomanometry in a group of 12 normal subjects and a group of 12 patients suffering from nasal obstruction. The method, based upon a simplified mathematical model of nasal airflow and utilizing logarithmic transformation of inspiratory pressure and flow data, improved the sensitivity and specificity of rhinomanometry and gave a more comprehensive index of nasal function.
