Snoring is a very common human habit, and for this reason it is considered more a social nuisance that a disease symptom. The nasal valve area has the minimal cross-sectional area of the upper airways. A problem at this level may easily induce impaired breathing and consequently snoring, therefore nasal dilation might significantly improve this complaint. Nas-Air® is a new internal nasal dilator which was tested on 41 outpatients who snore. Snoring duration, assessed by smartphone, visual analogue scale for the perception of sleep quality were measured before and during Nas-Air® use. A significant reduction of snoring time and an improvement of sleep quality were achieved during Nas-Air® wearing. In conclusion, the present study demonstrates that Nas-Air® is an internal nasal dilator able to reduce snoring time and improve sleep quality.
