Nasal obstruction frequently has been associated with sleep-disordered breathing as a potential etiologic factor.
Nasal obstruction results in pathologic changes in airflow velocity and resistance.
Experimentally produced nasal obstruction increases resistance and leads to sleep-disordered breathing events, including apnea, hypopnea, and snoring.
Clinical research examining the correlation between nasal obstruction and sleep-disordered breathing is limited, especially in regard to patients with conditions that increase nasal resistance, such as rhinitis and sinusitis.
To further identify risk factors for sleep-disordered breathing, the role of chronic and acute nasal congestion was investigated in a population-based sample.
Data on nasal congestion history and sleep problems were obtained by questionnaire (n=4927) and by objective inlaboratory measurement (n=911).
Participants who often or almost always experienced nighttime symptoms of rhinitis (5 or more nights a month) were significantly (p<0.0001) more likely to report habitual snoring (3 to 7 nights a week), chronic excessive daytime sleepiness, or chronic nonrestorative sleep than were those who rarely or never had symptoms.
Habitual snorers had significantly (p<0.02) lower air flow than nonsnorers, although a linear relation between decreased airflow and sleep-disordered breathing severity did not exist.
Participants who reported nasal congestion due to allergy were 1. (...)
