Subglottic stenosis is the condition that results when the larynx (voice box) becomes too narrow in a certain spot called the cricoid cartilage, the area below the vocal cords (subglottis) and above the trachea. Scarring in the larynx often causes this stenosis (narrowing).

Our Center for Airway Disorders provides the most advanced, minimally invasive and open airway procedures available. Our team approach includes the expertise of specialists from various fields who provide comprehensive assessment, treatment and follow-up care.

Subglottic stenosis is one of the most common abnormalities requiring tracheostomy in children younger than 1 year of age. At Boston Children’s Hospital, our team has world-renown expertise in tracheostomy but performs this procedure only as a last resort.

What is Subglottic Stenosis?

Subglottic stenosis is a narrowing of the airway below the vocal cords and above the trachea. This disorder involves the narrowing of the cricoid—the only complete ring of cartilage in the airway.  Scarring in the larynx just below the vocal cords often causes the narrowing of this cartilage. It may also involve the vocal cords and affect your child’s voice.

Boston Children’s is so much more than a hospital—it’s a community of researchers, clinicians, administrators, support staff, innovators, teachers, patients and families, all working together to make the impossible possible. ”
