Epiglottitis can be cured, but it is difficult to avoid recurrence, can only improve the living habits to avoid recurrence. The recurrence of epiglottitis is related to infection, allergic reaction and traumatic stimulation.1. Infection: the most common cause of epiglottitis recurrence is infection. The main reason is that Haemophilus influenzae type B infects the neighboring tissues of the throat, and people who are physically weak are easy to get infected again, so it is not guaranteed that there will be no recurrence at all. 2. Metamorphic reaction: metamorphic reaction is commonly known as allergy, which will cause vasodilation and increase permeability. It may be stimulated by drugs, food and other factors to cause allergies, which in turn leads to the recurrence of epiglottitis. 3. Traumatic stimulation: damage to the epiglottis mucosa can lead to inflammatory changes in the pharyngeal mucosa, such as fishbone stuck in the throat, laryngeal trauma and so on easily induced epiglottitis. Patients with epiglottitis should go to a regular hospital and follow the doctor’s instructions for standardized treatment, so as to avoid inappropriate treatment delaying the condition or causing the condition to recur.
