laryngotracheomalacia
Pronunciation: lar-ing-go-TRAY-kee-oh-muh-LAY-shuh
Congenital condition where cartilage of the larynx and trachea is abnormally soft, causing airway collapse.
Full Definition
Laryngotracheomalacia is a congenital disorder characterized by abnormal softening of the cartilaginous framework of the larynx and trachea, leading to dynamic airway collapse during breathing. It presents with inspiratory stridor that worsens with agitation, feeding difficulties, and potential respiratory distress. The condition can be isolated or associated with other airway anomalies or genetic syndromes. Mild cases may improve with growth as cartilage matures, while severe cases may require surgical intervention such as supraglottoplasty or tracheostomy. Flexible laryngoscopy and bronchoscopy are essential for diagnosis and assessment of severity.
Usage
Usage note: Distinct from laryngomalacia (existing term) - this involves both laryngeal and tracheal cartilage abnormalities.
