Laryngotracheal Stenosis

What is Laryngotracheal Stenosis (LS)?
Laryngotracheal stenosis (LS), a narrowing of the larynx and/or trachea, is a condition that can occur in infants and children for several reasons. Acquired LS develops as a result of trauma to the larynx and trachea, usually from endotracheal intubation, whilecongenital LS is a narrowing present at birth. Neck trauma, inhalation burns, and prolonged intubation can also lead to LS.


  • Stridor (noisy breathing)
  • Feeding problems
  • Croup, a loud cough that sounds like barking
  • Recurrent or severe croup


  • Physical exam
  • Imaging tests of the larynx and trachea including neck X-Rays, fluoroscopy, and CT scans
  • Airway endoscopy in the office and in the operating room

This condition may require surgical correction if severe.
