Analysis of obstruction site in obstructive sleep apnea syndrome patients by drug induced sleep endoscopy

Lateral pharyngeal wall collapse associated with hypoxemia in obstructive sleep apnea

“…An analysis of individual collapse patterns revealed that patients with complete lateral oropharyngeal collapse had significantly higher AHI and BMI as compared to patients with no oropharyngeal collapse. Koo et al reported similar findings in their study of Korean men with OSA. Analysis of other parameters indicative of nocturnal hypoxemia, such as ODI, T < 90%, and minimal SaO 2 also showed significant associations with complete lateral oropharyngeal collapse.…”

Drug-induced sleep endoscopy in children with Prader-Willi syndrome

“…Multilevel airway obstruction was observed in six out of nine children with PWS (66.6 %). In accordance with previous DISE studies in children and adults with OSA [15][16][17][18], our study provided the evidence that the majority of children with PWS had obstruction at multiple sites of the upper airway. The velum was the most common site of obstruction in our study (100 %) as an isolated entity or as part of a multilevel obstruction.…”

Drug-induced sleep endoscopy

“…12 Other studies have found a statistically significant correlation of increasing AHI and increasing DISE scores, by using slightly modified VOTE classification systems. 10,24 These results indicate that DISE does agree with the findings of polysomnography.…”
