On the relation of nasal cycling with nasal airway dimensions

Abstract

The size and configuration of the nasal airways of humans change with time as a result of the normal process of congestion/decongestion of the erectile tissue of the nasal mucosa. To determine the extent to which airway areas change in vivo, we used magnetic resonance imaging (MRI) to quantitate both the cross-sectional area and perimeter of coronal sections of the entire nasal airway of a human subject. Changes in airway size or patency were indexed to measured changes in unilateral nasal airway resistance determined by posterior rhino manometry. The results of this study in which two MRI scans were performed for presumed left-side patency and two for right-side patency, showed that changes in nasal airway resistance were difficult to ascribe to systematic changes In the sizes of the airways.
