BACKGROUND Nasal obstruction is one of the most bothering allergic rhinitis (AR) symptoms and there is a need for objective parameters to complement clinical evaluation due to blunted perception in many patients. In this study we compare measures of peak nasal inspiratory flow (PNIF) and peak nasal expiratory flow (PNEF) in patients with AR and in individuals without nasal symptoms and correlate them with the perception of nasal obstruction. METHODS A comparative cross-sectional study was… CONTINUE READING
