Impact of nasal XXXX .

@entity1 @entity26 @entity27 @entity387
OBJECTIVES: The purpose of this study was to investigate the relationship between nasal obstruction and @entity387 . The effect of postoperative nasal packing on sleep parameters was compared between @entity1 with @entity27 ( @entity27 ) and those with moderate/severe @entity27 . STUDY DESIGN: A prospective, nonrandomized controlled study. SETTING: Tertiary care center. SUBJECTS AND METHODS: @entity1 were recruited among adult @entity1 with a history of snoring scheduled to undergo nasal surgery from November 2009 to February 2010. All subjects underwent polysomnogram (PSG) testing within 30 days prior to surgery. @entity1 underwent nasal surgery and received postoperative nasal packing, and a PSG was repeated on the first postoperative night with nasal packing in place. Outcome measures included a change in respiratory disturbance index (RDI), minimum @entity26 saturation, @entity26 desaturation index (ODI), and duration of snoring. RESULTS: Forty-nine @entity1 were included in the study. @entity1 were stratified into 2 groups: those with RDI >= 15 (n = 23) and those with RDI <15 (n = 26). Nasal packing was found to significantly increase RDI (5.2    4.0 vs 10.4    10.0; P = .0001), duration of snoring (86.5%    13.1% vs 79.3%    15.3%; P = .008), and ODI (7.6    7.1 vs 9.9    7.4; P = .001) in @entity1 with mild @entity27 but not in @entity1 with moderate/severe @entity27 . Mean minimum arterial @entity26 saturation was unchanged in both groups. CONCLUSION: Postoperative nasal packing aggravated measures of @entity27 in @entity1 with mild @entity27 but not in @entity1 with moderate/severe @entity27 .
