Abstract:
Classic laryngomalacia presents in the awake infant with progressive stridor when agitated. Occult laryngomalacia usually presents with stridor in children older than 2 years and is limited to sleep or exercise. There have been no documented cases of occult laryngomalacia causing obstructive sleep apnea in infants. We report the youngest documented case of an infant with state-dependent laryngomalacia resulting in severe obstructive sleep apnea. This patient was successfully treated with supraglottoplasty, with resolution of symptoms. In conclusion, state-dependent laryngomalacia resulting in obstructive sleep apnea may present in children younger than 12 months of age. In these individuals, supraglottoplasty should be considered.
