Whether to recommend adenotonsillectomy versus watchful waiting for young children with obstructive sleep apnea (OSA) is often a difficult decision. To address this issue, researchers at a single center in Sweden randomized 60 otherwise healthy children (ages 2–5 years at first polysomnogram) with mild or moderate OSA to adenotonsillectomy or watchful waiting. Severity of apnea/hypoxia (measured with the obstructive apnea-hypoxia index [OAHI]), clinical symptoms, and quality of life (measured with the OSA-18 questionnaire) were assessed at baseline and after 6 months. Mild OSA was defined as an (OAHI) score ≥2 and <5, moderate OSA as a score ≥5 and <10.
At 6 months, OAHI scores had decreased in both the adenotonsillectomy and watchful waitin…
