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.

Diagnosis
