The epiglottis is a leaf-shaped flap of cartilage located behind the tongue, at the top of the larynx, or voice box. The main function of the epiglottis is to seal off the windpipe during eating, so that food is not accidentally inhaled.
Epiglottitis is usually caused by an infection from Haemophilus influenza type b (Hib) bacteria, the same bacteria that cause pneumonia and meningitis. Transmission of the bacteria is the same as with the common cold: Droplets of saliva or mucus are spread into the air when a carrier of the bacteria coughs or sneezes.
The epiglottis is a leaf-shaped flap in the throat that prevents food from entering the windpipe and the lungs. It stands open during breathing, allowing air into the larynx.
Most people with epiglottitis recover without problems. However, when epiglottitis is not diagnosed and treated early or properly, the prognosis is poor, and the condition can be fatal. Epiglottitis also can occur with other infections in adults, such as pneumonia.
