    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.

    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]

    en.wikipedia.org/wiki/Croup

    Croup (/ k r uː p / KROOP), also known as croupy cough, is a type of respiratory infection that is usually caused by a virus. [2] The infection leads to swelling inside the trachea, which interferes with normal breathing and produces the classic symptoms of "barking/brassy" cough, inspiratory stridor and a hoarse voice. [2]

  5. Epiglottis - Wikipedia

    en.wikipedia.org/wiki/Epiglottis

    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] The incidence of epiglottitis ...

  6. Laryngomalacia - Wikipedia

    en.wikipedia.org/wiki/Laryngomalacia

    These bands are known as the aryepiglottic folds. The shortened aryepiglottic folds cause the epiglottis to be curled on itself. This is the well known "omega shaped" epiglottis in laryngomalacia. Another common finding of laryngomalacia involves the posterior or back part of the larynx, where the arytenoid cartilages or the mucosa/tissue over ...

    en.wikipedia.org/wiki/Vocal_cord_dysfunction

    Vocal cord dysfunction (VCD) is a condition affecting the vocal cords. [1] It is characterized by abnormal closure of the vocal folds, which can result in significant difficulties and distress during breathing, particularly during inhalation.

  8. Respiratory disease - Wikipedia

    en.wikipedia.org/wiki/Respiratory_disease

    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.

  9. Subglottic stenosis - Wikipedia

    en.wikipedia.org/wiki/Subglottic_stenosis

    People affected by subglottic stenosis have a FEV1 of over 10. [2] Subglottic stenosis is graded according to the Cotton-Myer classification system from one to four based on the severity of the blockage. Grade 1 is up to 50% obstruction, Grade 2 is 50-70% obstruction, Grade 3 is 70-99% obstruction, and Grade 4 is with no visible lumen. [5]
