Evaluation of the upper airway in children and adolescents with cystic fibrosis and obstructive sleep apnea syndrome.

Objective: Obstructive sleep apnea syndrome (OSAS) in cystic fibrosis (CF) patients may be associated with the presence of upper airway obstruction caused by chronic infection and nasal polyposis that may also contribute to OSAS severity. Our objective was to identify the profile of findings in CF and OSAS patients by performing upper airway examinations.

Methodology: Observational, cross-sectional study involving 63 children and adolescents between the ages of 2 and 14 with CF.
