Tracheomalacia/Laryngomalacia: Tracheomalacia/Laryngomalacia - etiology
(The 5-Minute Pediatric Consult)

• Laryngomalacia:
  • Multiple factors likely involved
  • Inward collapse of aryepiglottic folds (cuneiform cartilages) during inspiration
  • Elongated, flaccid, omega-shaped epiglottis prolapses posteriorly into the pharynx during inspiration
  • Immaturity of the laryngeal cartilage results in weakness and collapse during inspiration.
  • Immaturity of neuromuscular control results in hypotonia of pharyngeal muscles.
• Tracheomalacia:
  • Weakness of the tracheal wall secondary to softening of the anterior cartilaginous rings and to decreased tone of the posterior membranous wall
  • During exhalation, increased collapsing pressure across a compliant airway wall causes invagination of the posterior membrane.
  • With increasing age, the length, area, thickness, and amount of cartilage increases in the anterior rings, as well as the size and contractility of the membranous wall.
