BACKGROUND: We sought to determine the ability of the endoscopic Mueller maneuver (MM) to predict the severity of OSAS based on upper airway (UA) collapse. METHODS: This chart review retrospectively analyzed the results of endoscopic Mueller maneuvers examining the UA on 506 @entity1 suspected of having OSAS. There were 3 areas of UA collapse that were evaluated: velopharynx (VP), base of tongue (BOT), and lateral pharyngeal walls (LPW). A sleep study was done after the examination to assess the severity of OSAS based on the @entity27 index (AHI). RESULTS: A total of 506 @entity1 met criteria for OSAS, with 194 mild cases (5    <=   AHI   <   15), 163 moderate cases (15    <=   AHI   <   30) and 149 severe cases (30    <=   AHI). At the VP, 30 @entity1 had minimal collapse (mean AHI   =   17); 41 @entity1 had moderate @entity891 (mean AHI   =   25); 392 @entity1 had severe @entity891 (mean AHI   =   27). At the BOT, 144 @entity1 had minimal collapse (mean AHI   =   19); 187 @entity1 had moderate @entity5773 (mean AHI   =   24); 175 @entity1 had severe @entity5773 (mean AHI   =   33). At the LPW, 158 @entity1 had minimal collapse (mean AHI   =   20); 109 @entity1 had moderate @entity7551 (mean AHI   =   25); 120 @entity1 had severe @entity7551 (mean AHI =33). The correlations found between @entity891 , @entity5773 , and @entity7551 and OSAS severity were: r   =   0.069 (95  % CI; -0.022, 0.16), r   =   0.26 (95  % CI; 0.18, 0.34) and r   =   0.22 (95  % CI; 0.12, 0.31), respectively. CONCLUSIONS: In this study, the degree of collapse of the UA at all levels, especially at the BOT and LPW levels, correlate significantly with the severity of OSAS. The Mueller maneuver helped identify @entity1 with severe @entity387 based on UA collapse. The MM cannot be used to diagnose OSAS, but can be a valuable tool to help the physician estimate the severity of @entity387 and the urgency to obtain a sleep study.
