What is epiglottitis and what causes it?
Epiglottitis is a potentially life-threatening condition that occurs when the epiglottis — a small cartilage “lid” that covers your windpipe — swells, blocking the flow of air into your lungs. A number of factors can cause the epiglottis to swell — burns from hot liquids, direct injury to your throat and various infections.

Laryngitis is an inflammation of your voice box (larynx) from overuse, irritation or infection. Chronic laryngitis can cause vocal cord strain and injuries or growths on the vocal cords (polyps or nodules).
What is respiratory failure of the epiglottis?
Respiratory failure. The epiglottis is a small, movable “lid” just above the larynx that prevents food and drink from entering your windpipe. But if the epiglottis becomes swollen — either from infection or from injury — the airway narrows and may become completely blocked.
