SDB in children markedly differs from that seen in adults, in particular with respect to clinical manifestations, PSG (Polysomnography) findings, and treatment approaches. Pediatric SDB is due to a combination of increased upper airway resistance and repetitive pharyngeal collapsibility leading to intermittent hypoxemia and arousals during sleep. It is a common and highly prevalent disorder in pediatric age, affecting 4 to 11% of all children. If left untreated, it can result in serious morbid consequences including cardiovascular morbidity and neurocognitive dysfunction.
