Acquired subglottic stenosis is commonly seen in babies that were born prematurely and required long periods of ventilation by endotracheal tube. It is stenosis at the level of the cricoid cartilage.
The condition usually presents when the baby is attempted to be extubated. The condition may resolve spontaneously but, if the airway obstruction remains, may involve treatment via laryngotracheoplasty.
Note that this condition is not only seen in babies. Intubation or trauma at any age can lead to subglottic stenosis and a consequent airway obstruction.
The incidence is reduced by the use of uncuffed endotracheal tubes.
