Subglottic hemangiomas may form a large mass in the subglottic airway causing varying degrees of airway obstruction. They grow rapidly for at least 12-18 months followed by slow shrinking (called involution). However, not every subglottic hemangioma will shrink completely. Many require active intervention because of their life-threatening nature in the airway. Watch as a surgeon at The Children's Hospital of Philadelphia removes a subglottic hemangioma, and see the airway before and after treatment.
