CSA is relatively common in infants with laryngomalacia. There seems to be a higher prevalence of CSA in infants with certain risk factors, but none of the risk factors are statistically significant. The presence of CSA can lead to alteration in sleep architecture. In addition to clinical evaluation, polysomnography may be warranted for the evaluation of infants with laryngomalacia and associated complex medical conditions.

Oral PresentationsP117 required later in 6 patients. Age at the time of SGP significantly affected the incidence of additional procedures. Infants receiving SGP at an age greater than 6 months were more likely to require management of adenotonsillar hypertrophy (82.1%) than their younger counterparts (14.8%) (P < 0.05).Conclusions: Accessory upper airway obstruction due to adenoidal or adenotonsillar hypertrophy, both synchronous and non-synchronous (occurring after) is more common in patients with severe laryngomalacia. Infants older than 6 months receiving SGP are more likely to require additional procedures to relieve upper airway symptoms. Management of accessory sources of upper airway obstruction should be explored in infants with laryngomalacia.
