Laryngotracheomalacia

Last edited: 4/15/2026

Overview

Laryngotracheomalacia is a congenital or acquired condition characterized by dynamic airway collapse during inspiration, leading to respiratory distress, stridor, and potentially life-threatening airway obstruction. 1

Diagnosis

  • Clinical presentation includes inspiratory stridor, particularly during feeding or activity.
  • Flexible laryngoscopy often reveals collapse of supraglottic structures during inspiration.
  • Imaging studies like CT or MRI may help assess the extent of airway narrowing but are not routinely required for diagnosis. 1
  • Management

  • Single-stage Laryngotracheal Reconstruction (SS-LTR): Combines stabilization, healing, and decannulation into a single procedure with postoperative intubation. Effective for managing complex laryngotracheal stenosis. 1
  • Cartilage Grafts: Utilized in reconstructive procedures to widen and stabilize the airway lumen. 1
  • Endotracheal Tube Stenting: Postoperative intubation supports airway patency during healing. 1
  • Special Populations

  • Pediatrics: SS-LTR is increasingly utilized in pediatric patients, accounting for 30% of LTR procedures by 1993, indicating its efficacy and acceptance in this population. 1
  • Key Recommendations

  • Consider single-stage laryngotracheal reconstruction (SS-LTR) for managing laryngotracheomalacia, especially in pediatric patients, to streamline stabilization, healing, and decannulation processes. (Evidence: Moderate) 1
  • Employ postoperative intubation as part of SS-LTR to ensure airway patency during the critical healing phase. (Evidence: Moderate) 1
  • Utilize cartilage grafts in reconstructive procedures to effectively widen and stabilize the airway lumen in cases of laryngotracheomalacia. (Evidence: Weak) 1
