Adenotonsillar hypertophy is the main cause and its treatment is surgical. The primary objective of this paper is to describe the pediatric population that is admitted to our Multidisciplinary Sleep Unit (MSU) for study of suspected OSA.Methods: Observational retrospective study in which a Polysomnography (PSG) was performed to 87 children derived from Pediatric Pulmonology consult for suspected OSA between December2009-January.Contingency tables and Fisher's P were used for data analysis.Results: In our studied population: 34.5% female and 65.5% male; median age: 6.42 years; 7.2% overweight and 27.7% obese.OSA was diagnosed in 37.9% (72.72% male,27.27% female); 3.4% mild, 12.36% moderate,21.8% severe OSA. Their symptoms were: snoring 100%, observed apneas 97%, restless sleep 72.7%, labored breathing 45.5% and enuresis 40.6%. Significant association was found between OSA and obesity, observed apneas, enuresis, adenoid and tonsillar hypertrophy (p 0.04, p 0.02, p 0.024, p 0.027, p 0.040 respectively). Mean PSG parameters: sleep efficiency: 79.32%, AHI: 19/hour, Oxygen desaturation index (IDO): 14.35/hr, time under 90% oxygen saturation (T90): 3.97% and mean microarousal index: 19.56/hr. Surgically treatment performed in 60% (75% adenotonsillectomy, 20% adenoidectomy, 5% tonsillectomy)Conclusions: 1. Enuresis, observed apneas, adenotonsillar hypertrophy and BMI had a significant association with OSA in our pediatric population. ER -
