Do the apnea-hypopnea index (AHI) and lowest oxygen saturation (LSAT) in children with obstructive sleep apnea (OSA) improve following isolated supraglottoplasty for laryngomalacia?
Background: A subset of children with OSA has laryngomalacia, in which supraglottic tissue collapses and subsequently obstructs normal airflow, which can lead to inspiratory stridor. In congenital laryngomalacia (CL), patients have symptoms during wakefulness and sleep; in sleep exclusive laryngomalacia (SEL), the collapse occurs only during sleep. Studies have reported that supraglottoplasty has successfully treated or even cured OSA in patients with laryngomalacia.
