The present study demonstrates highly significant associations between the subjective sensation of nasal obstruction and corresponding measures for nasal cavity volume, area, and airflow. We conclude that AR and PNIF are valuable objective instruments for evaluation of subjective nasal obstruction.
Our study indicates statistically significant associations between nasal cavity dimensions and PNIF. The most important structural determinant for PNIF is the minimal cross-sectional area of the nasal cavity.
We have clearly demonstrated an association between subjective nasal obstruction and reversible congestion of the nasal mucosa by employing the NCI. The measure has proven to be useful for evaluating patients with complaints of nasal obstruction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
