The role of upper airway morphology in apnea versus hypopnea predominant obstructive sleep apnea patients: an exploratory study.

CONCLUSIONS: Decrease in airway volume doesn't signify the type of respiratory event, but significant narrowing of velopharynx in both dimensions; thus having the narrowest value below a certain level causes more apnea. Advances in knowledge: We did not find a similar study when we did a literature search, showing the relationship of apnea versus hypopnea predominance and upper airway parameters in computerized tomography in patients with OSA.
