PURPOSE: Review drug-induced sleep endoscopy (DISE) findings in children with Prader-Willi syndrome (PWS) and correlate the patterns of airway collapse with apnea-hypopnea index (AHI) and body mass index (BMI).
METHODS: A total of nine children with PWS underwent DISE. DISE findings were recorded using the VOTE classification system. The relationship between different patterns of airway collapse with AHI and BMI was analyzed.
RESULTS: The majority of children with PWS were found to have multilevel obstruction (six out of nine children, 66.6 %). The velum was the most common site of obstruction (nine out of nine children, 100 %). All of the patients had positional obstructive sleep apnea (OSA). Patients with partial or complete anterior-posterior tongue base collapse were associated with a significantly higher AHI (P = 0.016) compared to patients with no anterior-posterior tongue base collapse. Apart from tongue base collapse, no other patterns of airway collapse showed a consistent association with AHI in our results. No patterns of airway collapse showed a significant association with BMI in our study.
CONCLUSIONS: In our study, partial or complete anterior-posterior tongue base collapse was associated with higher AHI values in children with PWS. Therefore, careful attention should be addressed to the management of tongue base collapse. Positional therapy could be a potential treatment for patients with PWS since it may alleviate the severity of tongue base collapse.
