Objective and Subjective Effects of a Prototype Nasal Dilator Strip on Sleep in Subjects with Chronic Nocturnal Nasal Congestion.

ABSTRACT:

Introduction

This exploratory study characterized the performance of a nasal dilator strip with improved spring forces in lowering nasal resistance during sleep and reducing sleep-disordered breathing in subjects with difficulty sleeping due to chronic nocturnal nasal congestion.

Methods

Subjects applied the strip at bedtime for 28 days (active phase; n = 70). Objective assessments included snoring variables, breathing route during sleep, and polysomnography measures compared with baseline. Nasal breathing, congestion, and sleep were measured subjectively using rating scales and questionnaires. During a crossover nasal resistance phase (n = 55), nasal resistance was measured using posterior rhinomanometry with the strip applied on one of two nights.
