Tracheal Stenosis

Tracheal Stenosis Symptoms and Causes

Tracheal stenosis is a narrowing of the trachea (windpipe) that is caused by an injury or a birth defect.

Acquired tracheal stenosis (narrowing from injury) is a reaction to repeated irritation by something, such as a breathing tube. It may also be a reaction to tissue injury caused by the pressure of a breathing tube cuff.

Congenital tracheal stenosis (narrowing due to a birth defect) is a rare condition in which the cartilage "rings" in the trachea, normally two half-round pieces of cartilage facing one another fuse together into solid rings during fetal development. This makes the airway very narrow and prevents it from growing.

Some signs of tracheal stenosis are noisy breathing, recurring pneumonia and wheezing.
