[1] [2] As the epiglottis is in the upper airway, swelling can interfere with breathing. [7] People may lean forward in an effort to open the airway. [1] As the condition worsens, stridor and bluish skin may occur. [1] Epiglottitis was historically mostly caused by infection by H. influenzae type b (commonly referred to as "Hib"). [1]
The epiglottis may be inflamed in a condition called epiglottitis, which is most commonly due to the vaccine-preventable bacterium Haemophilus influenzae. Dysfunction may cause the inhalation of food, called aspiration, which may lead to pneumonia or airway obstruction. The epiglottis is also an important landmark for intubation.
Allergic reactions are a relatively common cause of throat swelling in general, but sometimes the uvula can be affected alone. “This is known as uvular angioedema,” says Dr. Morrison.

The most common cause of epiglottitis is an infection by the bacteria, H influenza. The condition may present all of a sudden with high fever, severe sore throat, difficult and painful swallowing , drooling saliva, hoarse voice, difficulty breathing and malaise.
The symptoms are rarely life-threatening, though edema of the epiglottis can make breathing difficult, edema of the brain can cause reduced alertness, and in less than 5% of cases of SVCO, severe neurological symptoms or airway compromise are reported. Resolution of superior vena cava syndrome is directly related to the treatment of the ...
