What is laryngotracheal stenosis?

Laryngotracheal stenosis (LS), a narrowing of the larynx 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, while congenital LS is a narrowing present at birth. Neck trauma, inhalation burns and prolonged intubation can also lead to LS.

Diagnosis
