A subjective evaluation of a nasal dilator on sleep & snoring.
A noninvasive external nasal dilator device was used by 20 subjects with a history of mild snoring in a 2 week open label study. The baseline assessments were obtained during the first week. Treatment effects were evaluated during the second week. Subjects were evaluated using: pre- and post-sleep questionnaires; Stanford Sleepiness Scales completed at breakfast, lunch and dinner; and post-sleep bed partner questionnaires. All twenty subjects completed the study. A significant number of subjects' scores improved for sleepiness. Mean scores for the subjective assessment for ease of breathing during sleep improved compared to baseline by 25.6%, snoring loudness improved by 34%, sleep quality improved by 21.8%, and the Stanford Sleepiness Scale revealed a 26% reduction in daytime sleepiness.
