What is the definition or description of: larynx obstruction?

Larynx obstruction: Anything that blocks the lumen of the airway at the larynx level, is called laryngeal obstruction, or vocal cords. Mucous can be cleared with suction or spitting it out. Swelling and edema can occur when people have infection of these structures or one has a breathing tube put in their airway for breathing. Scarring can occur that can block the airway if one is not careful. Good luck.
