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. 1Diagnosis
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. 1Management
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. 1Special 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. 1Key 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) 1References
