Background

  • Congenital narrowing of the larygeal cartilage that causes upper airway obstruction and problems with swallowing.
    • A frequent complication of surgical repair of esophageal atresia (EA) and TEF
  • Most common cause of stridor in infancy
    • Typically infant to <2 years
  • Affects the epiglottis and/or arytenoid cartilages
  • When the epiglottis is usually folds in on itself because it is abnormally elongated, and the arytenoid cartilages are abnormally large. Because the misshapen epiglottis does not function properly, it can prolapse during inspiration, causing a high pitched "stridor".

Clinical Features

  • Infants
    • Brassy, barking cough
    • Can also develop “dying/death spells” that begin after 2–3 months of age[1]
      • Characterized by cyanosis, apnea, bradycardia, and hypotonia that require resuscitation[2]
  • Severe

Differential Diagnosis

Abscesses

Neoplastic Disorders

  • Neoplasms/tumors

Allergic and Auto-Immune Disorders

  • Spasmodic/tracheobronchitis
  • Angioedema/Angioneurotic edema

Metabolic, Storage Disorders

Evaluation

  • High clinical suspicion
  • ENT consult for nasopharyngoscopy vs. bronchoscopy

Workup

Management

  • Close observation
  • Recurrent “death spells”
    • May require more invasive intervention such as nasal CPAP temporarily
  • Aortopexy or tracheostomy for long-term relief

Disposition

  • Admit
