Epiglottitis Overview

Epiglottitis is a medical emergency that may result in death if not treated quickly. The epiglottis is a flap of tissue that sits at the base of the tongue that keeps food from going into the trachea, or windpipe, during swallowing. When it gets infected and inflamed, it can obstruct, or close off, the windpipe, which may be fatal unless promptly treated.

Respiratory infection, environmental exposure, or trauma may result in inflammation and infection of other structures around the throat. This infection and inflammation may spread to involve the epiglottis as well as other upper airway structures. Epiglottitis usually begins as an inflammation and swelling between the base of the tongue and the epiglottis. This may cause the throat structures to push the epiglottis backward. With continued inflammation and swelling of the epiglottis, complete blockage of the airway may occur, leading to suffocation and death. Autopsies of people with epiglottitis have shown distortion of the epiglottis and its associated structures including the formation of abscesses (pockets of infection). For unknown reasons, adults with epiglottic involvement are more likely than children to develop epiglottic abscesses.
