An infected epiglottis becomes swollen and causes issues with swallowing, speaking, and breathing due to its proximity to the esophagus and trachea. Other labeled structures include the tongue (pink arrow) and vertebral bodies of the cervical spine (grey arrow) Stridor is a sign of upper airway obstruction and is a surgical emergency.

For this reason, acute epiglottitis is considered a medical emergency, because of the risk of obstruction of the pharynx. Epiglottitis is often managed with antibiotics, inhaled aerosolised epinephrine to act as a bronchodilator, and may require tracheal intubation or a tracheostomy if breathing is difficult. [8]
X-ray findings may include subglottic narrowing. The priority is to secure the patient's airway, and to rule out croup and epiglottitis which may be fatal. Suspicion for tracheitis should be high in cases of onset of airway obstruction that do not respond to racemic epinephrine. [citation needed]
The causes of upper airway obstructions can be acute or chronic. Acute causes of upper airway obstruction include foreign body aspiration, blunt trauma to the neck, infection, and swelling due to allergies or other inflammatory conditions. [3] In children, viral infections such as croup or epiglottitis are frequent causes. [4]
An upper respiratory tract infection (URTI) is an illness caused by an acute infection, which involves the upper respiratory tract, including the nose, sinuses, pharynx, larynx or trachea. [3] [4] This commonly includes nasal obstruction, sore throat, tonsillitis, pharyngitis, laryngitis, sinusitis, otitis media, and the common cold.
In radiology, the thumbprint sign, or thumbprinting, is a radiologic sign found on a radiograph that suggests the diagnosis of either epiglottitis or intestinal ischemia.. In a lateral C-spine radiograph, the sign is caused by a thickened free edge of the epiglottis, which causes it to appear more radiopaque than normal, resembling the distal thumb.
Epiglottitis is a bacterial infection of the larynx which causes life-threatening swelling of the epiglottis with a mortality rate of 7% in adults and 1% in children. [10] Haemophilus influenzae is still the primary cause even with vaccinations. Also Streptococcus pyogenes can cause epiglottitis.
