When to see a doctor
If you experience severe or worsening symptoms, seek immediate medical attention. Always consult with a healthcare professional for proper diagnosis and treatment.
Causes & Risk Factors
Several factors can contribute to Epiglottitis.
Epiglottitis develops when the epiglottis becomes infected and inflamed, usually due to bacterial invasion.
Epiglottitis develops when the epiglottis becomes infected and inflamed, usually due to bacterial invasion. The most common culprit today is Streptococcus pneumoniae, though Staphylococcus aureus, Haemophilus influenzae, and other bacteria can also trigger the condition. These germs typically enter through the respiratory tract and settle in the epiglottis tissue, causing rapid swelling.
Viral infections can also lead to epiglottis inflammation, though this tends to be less severe than bacterial cases.
Viral infections can also lead to epiglottis inflammation, though this tends to be less severe than bacterial cases. Viruses like those causing the common cold, flu, or chickenpox occasionally spread to the epiglottis. Some people develop epiglottitis after a viral upper respiratory infection weakens their immune defenses, allowing bacteria to take hold.
Non-infectious causes include direct injury to the throat from swallowing very hot liquids, caustic chemicals, or sharp objects.
Non-infectious causes include direct injury to the throat from swallowing very hot liquids, caustic chemicals, or sharp objects. Severe acid reflux can sometimes irritate the epiglottis enough to cause swelling. Drug reactions, particularly to certain medications, represent another potential trigger, though this occurs rarely.
Risk Factors
- Incomplete or missing Hib vaccination
- Compromised immune system from illness or medications
- Male gender - men affected slightly more often
- Age between 20-40 years for adults
- Diabetes or other chronic health conditions
- Recent upper respiratory tract infection
- Exposure to secondhand smoke
- Living in crowded conditions or institutional settings
- History of frequent throat infections
- Taking immunosuppressive medications
Diagnosis
How healthcare professionals diagnose Epiglottitis:
- 1
Diagnosing epiglottitis requires urgent medical evaluation, typically in an emergency room setting.
Diagnosing epiglottitis requires urgent medical evaluation, typically in an emergency room setting. Doctors prioritize securing the airway first, then confirming the diagnosis. The classic presentation of fever, severe throat pain, drooling, and breathing difficulty often points strongly toward epiglottitis, especially when symptoms develop rapidly over hours rather than days.

Direct examination of the throat is usually avoided in children because it might trigger complete airway blockage, but adults can often tolerate a careful look using a flexible laryngoscope.
Direct examination of the throat is usually avoided in children because it might trigger complete airway blockage, but adults can often tolerate a careful look using a flexible laryngoscope. This thin, lighted tube allows doctors to visualize the swollen, cherry-red epiglottis safely. Blood tests typically show elevated white blood cell counts indicating infection, and cultures help identify the specific bacteria responsible.

Imaging studies like lateral neck X-rays can reveal the classic "thumbprint sign" - a swollen epiglottis that looks like a thumbprint on the film.
Imaging studies like lateral neck X-rays can reveal the classic "thumbprint sign" - a swollen epiglottis that looks like a thumbprint on the film. However, X-rays aren't always necessary and shouldn't delay treatment. CT scans provide more detailed images but are reserved for unclear cases. The key is balancing diagnostic accuracy with the urgent need to protect the airway, since epiglottitis can progress from mild symptoms to complete airway obstruction within hours.
Complications
- Airway obstruction represents the most serious and immediate complication of epiglottitis.
- The swollen epiglottis can completely block breathing, leading to respiratory failure and death within hours if untreated.
- This explains why epiglottitis is considered a medical emergency requiring immediate hospital care.
- Even with prompt treatment, some patients require emergency intubation or tracheostomy to maintain breathing.
- Other complications occur less frequently but can be serious.
- The infection may spread to nearby tissues, causing deep neck abscesses or pneumonia.
- Some patients develop sepsis when bacteria enter the bloodstream, though this is uncommon with prompt antibiotic treatment.
- Long-term complications are rare, and most people recover completely without lasting effects on their voice or swallowing ability.
Prevention
- The most effective prevention strategy involves staying current with recommended vaccinations, particularly the Haemophilus influenzae type b (Hib) vaccine.
- This vaccine, routinely given to infants and toddlers, has dramatically reduced childhood epiglottitis cases.
- Adults who missed childhood vaccinations or have compromised immune systems should discuss catch-up vaccination with their doctors.
- General infection prevention measures help reduce overall risk.
- These include frequent handwashing, avoiding close contact with people who have respiratory infections, and maintaining good overall health through proper nutrition and adequate sleep.
- People with diabetes or other chronic conditions should work closely with their healthcare providers to keep these diseases well-controlled, as uncontrolled chronic illness increases infection susceptibility.
- While most cases occur randomly and can't be prevented, avoiding known irritants helps reduce risk.
- This means not smoking, limiting alcohol consumption, and being careful with very hot foods or drinks that could injure the throat.
- People with frequent throat infections should seek prompt treatment to prevent complications, though this rarely prevents epiglottitis specifically.
Emergency airway management takes absolute priority in epiglottitis treatment.
Emergency airway management takes absolute priority in epiglottitis treatment. Medical teams prepare for potential intubation or emergency tracheostomy before doing anything else. Many patients, especially adults with milder cases, can be managed without invasive airway procedures, but equipment stays ready at bedside. Humidified oxygen helps reduce inflammation and eases breathing while other treatments take effect.
Antibiotics form the cornerstone of treatment, typically starting with broad-spectrum intravenous medications like ceftriaxone or cefotaxime before culture results return.
Antibiotics form the cornerstone of treatment, typically starting with broad-spectrum intravenous medications like ceftriaxone or cefotaxime before culture results return. These powerful drugs target the most likely bacterial causes and usually begin working within 24-48 hours. Once specific bacteria are identified, doctors may switch to more targeted antibiotics. Treatment courses generally last 7-10 days, with the first few days given intravenously.
Corticosteroids like dexamethasone help reduce inflammation and swelling of the epiglottis, though their use remains somewhat controversial.
Corticosteroids like dexamethasone help reduce inflammation and swelling of the epiglottis, though their use remains somewhat controversial. Many doctors prescribe them for severe cases or when airway compromise seems imminent. Pain medication and fever reducers provide symptomatic relief, while patients often require IV fluids since swallowing remains painful initially.
Recent advances include better rapid diagnostic tests that identify causative bacteria faster, allowing for quicker targeted therapy.
Recent advances include better rapid diagnostic tests that identify causative bacteria faster, allowing for quicker targeted therapy. Improved intensive care monitoring and airway management techniques have also reduced the need for surgical airway interventions. Most patients show significant improvement within 48-72 hours of starting appropriate antibiotics, with complete resolution typically occurring within a week.
Living With Epiglottitis
During the acute phase of epiglottitis, patients typically require hospitalization for several days while receiving intravenous antibiotics and monitoring for breathing problems. The first 24-48 hours demand the most intensive care, with gradual improvement afterward. Most people can return to normal activities within a week or two, though some fatigue may persist as the body recovers from the infection.
