At what age do most cases of laryngomalacia resolve by?

Laryngomalacia is a common congenital laryngeal anomaly characterized by soft, floppy tissue above the vocal cords that collapses inward during inhalation, leading to stridor. Most cases of laryngomalacia are mild and typically resolve as the child grows. The condition is most prevalent in infancy, with many children showing improvement in symptoms as they approach about 8 to 12 months of age. This resolution is linked to the maturation of the larynx and overall airway dynamics as the child develops. By this age range, most children will have outgrown the condition, as the laryngeal structure becomes firmer and better supports normal breathing.

Although it's noted that some milder cases can resolve by 6-9 months, the most consistent and widely recognized timeline for significant resolution of laryngomalacia symptoms tends to be from 8 to 12 months. In contrast, while some cases may take longer to fully resolve, such as those persisting until 12-18 months or even up to 2 years, these scenarios are less common and typically indicate a longer-than-average duration of the condition.
