Population
This was a retrospective study of pediatric patients who underwent PSG in the sleep laboratory of the university hospital of Clermont-Ferrand, France, between September 2018 and March 2019.
All children selected for the analysis were referred for a suspicion of OSAHS. They were aged two to ten years and had tonsillar hypertrophy graded ≥ 2 on the Brodsky scale [19]. Patients with OSAHS type 2 and type 3 or with other sleep disorders than OSAHS were excluded. Sixteen children (11 girls and 5 boys) aged two to ten years (mean age 4.8 ± 1.8) were enrolled in the study. With an average body mass index (BMI) of 16.1 ± 2.4 kg/m2, they all had a BMI-for-age between the 5th and 95th percentiles.
Prior to sleep recording, all patients had undergone a comprehensive clinical examination performed by an otolaryngologist, consisting in measurements of weight in kilograms (kg) and height in meters (m), calculation of BMI (kg/m2) and tonsil grading according to the Brodsky scale [19]. All parents of included children completed the French version of the SHS questionnaire.
