Inflammation and swelling of the epiglottis.
Inflammation of the epiglottis, characterized by severe sore throat (pharyngitis), difficulty in swallowing (dysphagia), and fever. If untreated, complete airway obstruction with respiratory failure and death may result. It is most common in children 3-5 years old, but may also occur in adults. The cause is a bacterial infection (Hemophilus influenza). Treatment involves hospitalization, intravenous antibiotics, and possibly, placement of an endotracheal tube for breathing.
Severe infection or inflammation of the epiglottis and surrounding tissues which can result in stridor, respiratory distress, and partial to complete airway obstruction; occurs most commonly in children ages 2-12.
Inflammation and swelling of the leaf-shaped piece of fibrous cartilage (epiglottis) that covers the opening of the larynx (voice box) during swallowing to prevent solids or liquids from getting into the trachea.
A rare but serious inflammation of the epiglottis that can cause a child to suffocate if not treated immediately. The valve at the top of the windpipe (trachea) becomes swollen due to infection and can obstruct breathing. The bacteria Haemophilus influenzae type b is the most common cause. Children between the ages of 2 and 6 are most susceptible. The first signs of infection are a sore throat and high fever, rapidly progressing to noisy, hoarse, and labored breathing called stridor. Swallowing may become so difficult that a child drools.
Inflammation of the mucous membrane of the epiglottis. Swelling and inflammation of the tissues at the laryngeal entrance obstructs the air flow to the lungs, causing a dangerous form of croup.
Acute epiglottitis is a septicaemic illness which includes an acute inflammatory oedema of the epiglottis, due to Haemophilus influenzae. It progresses very rapidly and a child can be dangerously ill — or even die — within hours of onset. Once recognized, however, it is easily and successfully treated by immediate transfer to hospital for emergency intubation and ventilation and use of antibiotics and steroids. Fortunately it is now very rare as a result of the introduction of haemophilus vaccine into the primary vaccination course of infants.
Inflammation of the epiglottis as the result of infection. The severe swelling above the epiglottis may obstruct air flow and can cause death. Epiglottitis is an emergency and must be treated immediately.
Akin to a leaf, a cartilaginous structure emerges upwards from the larynx, assuming the role of a lid that can seal the trachea shut, effectively safeguarding the airway against the intrusion of food or liquid during swallowing.
