Abstract
Sleep apnea and the nasal airway.
Highlights
Perhaps the simplest way of improving the nasal airway is to mechanically dilate the nasal valve area, the site of minimum cross-sectional area in the normal nose
The active treatment was associated with a reduced arousal frequency but no improvement in the other polysomnographic variables – sleep architecture, apnea-hypopnea index (AHI) or oxygen saturation
The use of a nasal decongestant did not result in any improvement in either the AHI or snoring in 20 asymptomatic individuals with mild obstructive sleep apnea (OSA) [13]
Summary
Perhaps the simplest way of improving the nasal airway is to mechanically dilate the nasal valve area, the site of minimum cross-sectional area in the normal nose. Medication can be used to improve nasal obstruction in patients with OSA. Kerr and colleagues [12] used a randomized crossover study design to compare the effect of topical nasal decongestant in combination with stenting of the nasal vestibule with placebo (saline nose drops) in patients with OSA.
