PURPOSE: This study aimed to compare fiberoptic nasopharyngoscopy during Mueller's maneuver (FNMM) with @entity20202 ( @entity20202 ) for upper airway (UA) assessment in @entity1 with @entity27 and @entity387 . We also investigated the relationship between daytime endoscopic examinations and nocturnal pressure measurements. METHODS: We conducted a prospective, case-series study at Peking Union Medical College Hospital. All @entity1 were evaluated by daytime FNMM and @entity20202 . The retropalatal and retroglossal regions were continuously video recorded during quiet breathing, FNMM, and @entity20202 . We calculated the narrowing rate and determined the level of obstruction and pattern of collapse (lateral, anterior-posterior, or concentric). @entity1 also underwent nocturnal pressure measurements to identify obstruction sites. RESULTS: Ninety-two @entity1 were enrolled. FNMM and @entity20202 detected @entity3885 in every case. Fifty-six and 38 @entity1 had @entity3885 detected by FNMM and @entity20202 , respectively. There was diagnostic agreement between FNMM and @entity20202 in 72 @entity1 when diagnosing @entity3885 , but the patterns of collapse were different using each technique. Pressure measurements showed that lower @entity386 and @entity387 index (AHI) and the proportion of lower AHI were significantly lower in the isolated @entity3885 group than in the combined obstruction group diagnosed with either FNMM or @entity20202 (p   <   0.01). CONCLUSIONS: Daytime FNMM and @entity20202 are reliable for evaluating the level of obstruction and pattern of UA collapse, and correlate with sleep study findings. @entity20202 may provide some different information regarding patterns of collapse and @entity3885 from FNMM. Both techniques are helpful for determining surgical strategies.
