laryngomalacia
Pronunciation: lar-in-go-mal-A-sha
Softening of laryngeal cartilage causing inspiratory stridor and breathing difficulties in infants.
Full Definition
Laryngomalacia is the most common cause of stridor in newborns, characterized by immature, floppy laryngeal cartilage that collapses inward during inspiration. The condition typically presents with inspiratory stridor, feeding difficulties, and failure to thrive in severe cases. Most cases resolve spontaneously as cartilage matures, though severe cases may require surgical intervention. This diagnosis appears frequently in ENT consultations, sleep study reports, and pediatric pulmonology evaluations. The term's spelling and pronunciation often challenge medical transcriptionists and editors.
Usage
Usage note: Note the spelling with 'malacia' (softening). Distinguish from acute conditions like laryngitis or laryngospasm.
