Nasal influences on snoring and obstructive sleep apnea.
Although the relationship between nasal obstruction and sleep disturbance is variable, either partial or total obstruction of the nasal passages can cause snoring, obstructive sleep apnea, and the sequelae of alveolar hypoventilation. In addition, nasal obstruction can cause sleep fragmentation, sleep deprivation, and the known sequelae of disturbed sleep architecture, including associated daytime tiredness and alterations in normal behavior patterns. Nasal obstruction may produce greater physiologic effects during sleep than during the awake state. A complete examination of the upper respiratory tract should be done in all patients with obstructive sleep apnea and snoring. The degree of nasal obstruction is not directly correlated with the severity of symptoms and findings.
