Changes in sleep apnea after supraglottoplasty in infants with laryngomalacia.

Objective: To determine the clinical and polysomnography outcomes in infants with laryngomalacia undergoing supraglottoplasty.

Methods: Infants (<1 year old) who underwent polysomnography pre- and post-supraglottoplasty at our tertiary referral center between 2003 and 2009 were reviewed retrospectively. Outcome measures included changes in stridor, sleep disordered breathing, swallowing, and polysomnography parameters before and after surgery.
