Subglottic Stenosis.

The subglottis is a narrow region of the pediatric airway that is exquisitely susceptible to the development of airway stenosis. The incidence of acquired subglottic stenosis in the setting of prolonged intubation has significantly decreased because of improved endotracheal tube management protocols. Advances in otolaryngology interventions, such as balloon dilation and endoscopic cricoid split techniques, may allow the avoidance of tracheostomy in patients with mild to moderate subglottic stenosis. However, patients with severe subglottic stenosis are often tracheostomy dependent. Open surgical techniques to treat severe disease, such as laryngotracheal reconstruction and cricotracheal resection, offer high rates of tracheostomy decannulation.
