Abstract
Peak Nasal Inspiratory Flow: A Diagnostic Tool to Determine the Need for Septoplasty
Highlights
The nose is a major contributing factor for nasal resistance
The peak nasal inspiratory flow (PNIF) meter is a viable, noninvasive, easy to handle, and cost-effective alternative for the evaluation of nasal patency. It is an indirect measure of nasal obstruction, which considers that the increase in nasal resistance modifies the nasal airflow and the PNIF

Summary
Peak Nasal Inspiratory Flow: A Diagnostic Tool to Determine the Need for Septoplasty. The visual analog score (VAS) was used to clinically determine the severity of nasal obstruction and a peak nasal inspiratory flow (PNIF) meter was used to objectively test the severity of nasal obstruction. Objective tests that assess nasal patency must be comfortable, accurate, standardized, and easy to perform, clinically applicable, and must not impact nasal anatomy-physiology. The peak nasal inspiratory flow (PNIF) meter is a viable, noninvasive, easy to handle, and cost-effective alternative for the evaluation of nasal patency. It is an indirect measure of nasal obstruction, which considers that the increase in nasal resistance modifies the nasal airflow and the PNIF
