Abstract

Abstract : Purpose of review: Adenotonsillar hypertrophy is the most common pathogenetic contributor to obstructive sleep apnea syndrome (OSAS) in childhood, and adenotonsillectomy is the standard initial treatment. Here, we summarize the most recent evidence on the efficacy and complications of adenotonsillectomy and explore knowledge gaps in clinical management. Recent findings: Favorable adenotonsillectomy effects have been reported in children with very severe OSAS [apnea–hypopnea index (AHI) >20 episodes/h] and extremely severe OSAS (AHI >100 episodes/h), without postoperative mortality, need for endotracheal intubation, prolonged hospital stay or re-admission after hospital discharge. However, the risk of residual OSAS after adenotonsillectomy, which may reach 30–60%, has not been thoroughly established. Behavior, OSAS-related symptoms and quality of life improve postoperatively even in children with AHI 1–5 episodes/h. Natural history of enuresis resolution is accelerated postadenotonsillectomy and office-based systemic blood pressure is decreased in OSAS and hypertension. However, which children younger than 2 years should undergo adenotonsillectomy instead of adenoidectomy only to prevent recurrence of OSAS symptoms and revision surgery remains unclear. Adenotonsillectomy in children with Prader–Willi syndrome is frequently accompanied by postoperative residual OSAS while complications are not uncommon. Summary: In the last 2 years, several studies have provided evidence supporting the efficacy and safety of adenotonsillectomy as treatment intervention for otherwise healthy children with OSAS.
