  • Title: The role of nasal obstruction in obstructive sleep apnea syndrome.
    Author: Papsidero MJ.
    Journal: Ear Nose Throat J; 1993 Jan; 72(1):82-4. PubMed ID: 8444135.
    Abstract:
    In summary, there is much evidence in the literature that nasal obstruction causes obstructive sleep apnea, usually of mild to moderate degree, in many individuals. In addition, it is a contributory factor in individuals with severe obstructive sleep apnea. This appears to occur because of its contribution to upper airway resistance which directly or indirectly results in a reduction in intraluminal pressure during inspiration and collapse. Nasal obstruction via its influence on the so-called nasal-pulmonary reflex, may also result in alveolar hypoventilation. In patients who have symptoms consistent with obstructive sleep apnea syndrome and/or other disorders of excessive somnolence, a careful history eliciting findings of possible nasal obstruction as well as a thorough nasal examination is appropriate. If nasal obstruction is present, intervention should be considered as part of the routine therapy for obstructive sleep apnea syndrome.
