Taking into account the impact of nasal airway resistance on sleep-disordered breathing, the present results suggest that chronic nasal obstruction impairs QOL, at least partially, through excessive daytime sleepiness possibly caused by sleep-disordered breathing. We stress that sufficient and appropriate rhinologic treatment may improve the quality of daily and social activities of individuals with sinonasal diseases.

Induction of sleep-disordered breathing (SDB) is a possible cause of excessive daytime sleepiness and impaired QOL in subjects with nasal obstruction. A variant of SDB such as silent upper respiratory resistance syndrome may participate in this phenomenon in the absence of snoring.
