Description
Summary:ABSTRACT Background The role of objective nasal airflow measures using peak nasal inspiratory flow (PNIF) and rhinospirometry in supporting clinical examination findings when offering patients septoplasty remain undefined. Objective To explore the baseline relationships between clinical examination findings, subjective reported symptoms and objective nasal patency measures in nasal obstruction. Methods This is a sub‐study of the NAIROS trial. Participants with nasal obstruction secondary to septal deviation were included in this NAIROS sub‐study. The side of septal deviation, enlargement of inferior turbinate (IT), the need for IT reduction if septoplasty was being performed, the area of septum deflecting into the airway and observer rated airway block (ORAB–arbitrarily divided by 50% blockage) were assessed by clinicians. The subjective score of nasal obstruction was assessed using the Double Ordinal Assessed Subjective Scale (DOASS). Objective nasal patency measures (e.g., nasal partitioning ratio, [NPR] and PNIF) were measured using PNIF and rhinospirometry. Results The mean NPR for left‐sided, both‐sided and right‐sided septal deviation was −0.35, −0.02 and 0.51, respectively (p
