Abstract
When a “crowing” inspiratory stridor occurs in an infant or in a child, the chances are that he has a laryngeal lesion. In newborns and infants, almost all lesions—immature supraglottic cartilages, webs, cysts, laryngoceles, vocal cord paralysis, subglottic stenosis and hemangiomas—are congenital. In older children, infections, trauma or juvenile papillomas are more likely to be responsible.
