A simple, quick, validated method of recording the nasal cycle in humans using a subjective scale
Published online by Cambridge University Press: 16 November 2018
Abstract
Studies on the nasal cycle can be limited by time-consuming rhinomanometric measurements. However, quantifiable subjective assessment of nasal airflow has been limited by poor correlation with rhinomanometric data, even when investigating patients with a deviated nasal septum.
Thirty healthy participants attended two study days for rhinomanometric and subjective assessment of nasal airflow (using the subjective ordinal scale). A nasal partitioning ratio was calculated for both measures.
Objective and subjective nasal partitioning ratios were compared; strong correlations were seen, with a correlation coefficient of 0.64 (p < 0.00001) on day 1 and 0.68 (p < 0.00001) on day 2.
The use of the subjective ordinal scale and nasal partitioning ratio provides a sensitive tool for assessing relative nasal airflow, with results that correlate strongly with rhinomanometric data. This finding strongly suggests that this combination could be used for future subjective assessment of the nasal cycle.
