Condition
Pediatric Subglottic Stenosis
What You Need to Know
The subglottis is that portion of the airway located just below the vocal cords. It serves as the entry point of air into the trachea. Narrowing, or stenosis, of the subglottis can be a “congenital” anomaly that is present at or shortly after birth or an “acquired” condition that most commonly arises in infants who required prolonged airway intubation for ventilation.
Symptoms
Symptoms of subglottic stenosis include:
- Recurrent croup
- Shortness of breath
- Exercise intolerance
- Cough
Diagnosis
The diagnosis of subglottic stenosis usually requires “direct laryngoscopy and bronchoscopy” where the airway is examined in the operating room under general anesthesia.
Treatment
Depending on the severity of symptoms and the type of narrowing, treatment includes:
- Observation
- Balloon dilation
- Laser excision
- Open surgical airway reconstruction (sometimes)
