Epiglottitis, also termed supraglottitis or epiglottiditis, is an inflammation of structures above the insertion of the glottis and is most often caused by bacterial infection. Before widespread Haemophilus influenzae type b (Hib) vaccination, H influenzae caused almost all pediatric cases of epiglottitis.
The most common cause of epiglottitis in children was infection with Haemophilus influenzae type b (Hib) bacteria. The bacterium also causes pneumonia, meningitis and blood infections.
Adult supraglottitis is a serious and potentially life-threatening condition, characterised by inflammation of the supraglottic structures of the larynx, namely the arytenoids, the false vocal cords, the laryngeal ventricles, the aryepiglottic folds and the epiglottis.
Viral infections are the commonest cause. Bacterial infection with H influenzae type b, Str pneumoniae, and Staph aureus, although common in children, are rare in adults. Other causes include anaphylaxis, a sudden bleed into a laryngeal tumour, foreign bodies, blunt trauma, smoke inhalation, and caustic inges- tion.
If cancer is in the supraglottis or glottis, treatment may include the following: Chemotherapy and radiation therapy given together. Chemotherapy followed by chemotherapy and radiation therapy given together. Laryngectomy may be done if cancer remains.
This disease progresses rapidly to airway compromise. Patients are often drooling and leaning forward with the neck extended. Some patients may have stridor, but a muffled voice is more common. Management depends on establishing a secure airway by intubation and treating with antibiotics.
Supraglottic cancer involves a cancerous growth in the upper part of the larynx. Although supraglottic cancer arises from a combination of genetics and environmental factors, the exact causes are not always known. Tobacco and alcohol use are some of the biggest risk factors for developing supraglottic cancer.
Epiglottitis may be caused by infection (such as with bacteria, viruses, or fungi), environmental agents (such as chemicals or heat damage), allergic reactions, or trauma to the neck or throat. Epiglottitis is contagious.
The supraglottis describes the part of the larynx from above the vocal cords to the epiglottis. In epiglottitis, the epiglottis appears swollen, like a red sausage or ball, rather than a thin flap. In supraglottitis, the other supraglottic tissues behind the epiglottis appear swollen and red.

Epiglottitis (or supraglottitis) is a life-threatening infection of the airway proximal to the vocal cords (Fig. 1.9; see also Fig. 1.6). Historically, it was an infection in 1-4 year-old children caused by Haemophilus influenzae type b.
If left untreated, epiglottitis can progress to life-threatening airway obstruction, and thus remains a diagnosis not to be missed.
Supraglottic obstruction is a medical or surgical emergency. It can result in increased work of breathing and respiratory distress and can progress to fatal cardiopulmonary arrest.
In children, epiglottitis is usually caused by the bacteria Haemophilus influenzae (H influenzae) type B. In adults, it is often due to other bacteria such as Streptococcus pneumoniae, or viruses such as herpes simplex virus and varicella-zoster.
Bacterial tracheitis is also known as bacterial croup or acute laryngotracheobronchitis. It is a rare but often life-threatening upper airway disease that almost always occurs in children.
Introduction: Epiglottitis is a known life-threatening cause of airway obstruction that has numerous infectious and non-infectious etiologies. Here, we present the first case of COVID-19 induced acute epiglottitis in adults found in the literature.
The typical presentation in epiglottitis includes acute occurrence of high fever, severe sore throat and difficulty in swallowing with the sitting up and leaning forward position in order to enhance airflow. There is usually drooling because of difficulty and pain on swallowing.
Visible epiglottis is a rare anatomical variant which is usually asymptomatic without the need of any medical or surgical intervention. It is most commonly seen in children but there are some reports of its prevalence in adults too. Cases of visible epiglottis seem to be unfamiliar among dental professionals.
: situated or occurring above the glottis. supraglottic cancers.
The 5-year relative survival rate for this cancer is 45%. If the cancer is localized in the larynx, the 5-year relative survival rate is 61%. If the cancer is regional, the 5-year relative survival rate is 46%. The 5-year relative survival rate for distant cancer of the supraglottis is 30%.
The supraglottis comprises the section between the inferior boundary of the hyoid bone, epiglottis, and the vestibular folds, also known as the false vocal cords.
supraglottis which is situated between the base of tongue and the vocal cords, glottis composed of the vocal cords and the false vocal cords. subglottis which is a part of the larynx situated just below the vocal cords and upto the trachea.
They include regurgitation and aspiration of gastric contents, compression of vascular structures, trauma, and nerve injury. The incidence of such complications is quite low, but as some carry with them a significant degree of morbidity the need to follow manufacturers' advice is underlined.
Purpose: Acute supraglottic laryngitis (ASL) is manifested by supraglottic inflammation that has the potential for rapid and fatal airway obstruction. Complete/incomplete vocal fold immobility (VFIm) in the setting of ASL may contribute to airway obstruction.
