Timing and severity of presentation depend on the size of the cyst and its proximity to the glottis and range from severe prenatal airway obstruction leading to polyhydramnios and pulmonary hypoplasia to postnatal inspiratory stridor associated with muffled cry, hoarseness and cyanotic episodes, and to feeding difficulties and failure to thrive. It can be associated with laryngomalacia. SCTID:765763007 Orphanet:141124 UMLS:C0339880 MEDGEN:451040 MONDO:0015396 congenital
