Epidemiology
Absolute data for the incidence and prevalence of laryngomalacia (LM) are lacking. It is the most common source of stridor in infants and is the most common congenital laryngeal anomaly, accounting for 60% to 70% of cases.[1][2][3] LM occurs in almost twice as many males as females and presents in the first few weeks of life with resolution within 12 to 24 months.[10] Between 17% and 47% of patients with severe LM have been reported to have additional associated conditions or syndromes.[7][8]
