OBJECTIVE: @entity8968 is considered to be a potential etiological factor in @entity387 . However, a significant correlation between nasal measurements and @entity27 has not been demonstrated so far. The aim of this study was to investigate the relationships between nasal resistance, nasal volumes and selected sleep parameters using nasal measurements performed in both seated and supine positions. We also investigated whether snoring @entity1 in our clinical sample showed increased positional or decongestive nasal mucosal changes. MATERIAL AND METHODS: Forty-one snoring @entity1 on a waiting list for correction of nasal obstruction underwent polysomnography, anterior rhinomanometry and acoustic rhinometry. Nineteen non-snoring control subjects were also recruited. Nasal measurements were performed in a seated position, after lying down in a supine position and, after decongestion of nasal mucosa, in a seated position again. RESULTS: In the overall @entity1 group, nasal volume at a distance 2-4 cm from the nares in the supine position correlated inversely with @entity27 ( @entity27 ) (r = -0.32, p < 0.05) and @entity26 desaturation index (ODI) (r = -0.49, p < 0.05). In the @entity28 @entity1 , total nasal resistance measured in a supine position correlated with @entity27 (r = 0.50, p < 0.05) and ODI (r = 0.58, p < 0.05) and supine nasal volumes were also inversely correlated with ODI. No significant correlations were found between baseline nasal measurements performed in a seated position and sleep parameters. Postural or decongestive changes in nasal measurements were not increased in snoring @entity1 compared with control subjects. CONCLUSION: The relationship found between nasal measurements and sleep parameters suggests that nasal obstruction does augment airway collapse.
