Subglottic and Tracheal StenosisSubglottic and tracheal stenosis are two different terms used to describe a narrowing in the upper airway (trachea or windpipe) or in the area just below the vocal folds. This condition may be either congenital or acquired.

Causes of Subglottic and Tracheal Stenosis

There are many causes of subglottic stenosis and tracheal stenosis, but they all have their origins in an injury to the windpipe that results in a round scar, which ultimately narrows the breathing space. Acquired subglottic stenosis is most commonly caused by prolonged intubation.

Symptoms, Signs, Diagnosis of Subglottic and Tracheal Stenosis

If the injury is just below the vocal folds, it may interfere with the way the vocal folds work, leading to voice changes. An injury that is slightly lower down in the windpipe may cause difficulty breathing as the scar (stenosis) narrows the airway. Additional symptoms may include noisy breathing (inspiratory/expiratory stridor) and cough.

Treatment for Subglottic and Tracheal Stenosis

Many patients with this condition are treated with intermittent dilations of the trachea performed in the operating room. There are also cutting edge office therapies available for the treatment of this condition provided at the Voice and Swallowing Center
