UNLABELLED: Acoustic rhinometry, rhinomanometry and Inspiratory Peak Nasal Flow (IPNF) are used in order to objectively assess nasal patency. These are expensive not very practical tests, except for IPNF, which is a fast, simple and low cost method. OBJECTIVE: To assess IPNF in healthy individuals complaining of nose obstruction caused by allergic rhinitis. METHOD: IPNF use in 78 individuals with and without rhinitis symptoms. STUDY DESIGN: Contemporary cross-sectional cohort. RESULTS: IPNF showed significant results for nasal obstruction, rhinorrhea, pruritus, sneezes and tearing (p < 0. 001). There was no correlation between the presence of nasal septum deviation and IPNF (p = 0. 561). We found a positive correlation between IPNF and the Visual Analogue Scale (VAS) for nasal obstruction (p = 0. 002). In the multiple linear regression model, there was a statistical significance between the values found in IPNF with allergic rhinitis and age (p = 0. 005 and p = 0. 023 respectively). CONCLUSIONS: IPNF proved to be a reliable method to detect changes in nasal patency, by obstructive causes as well as inflammatory causes, with an acceptable level of statistical significance, simple, easy to handle, inexpensive and reproducible.
