Epiglottic cysts usually do not go away on their own. However, if there are no symptoms, they usually do not require treatment and can be checked regularly. An epiglottic cyst is a relatively common benign swelling in the throat. It is not easily detected when the cyst is small because there are no obvious physical abnormalities and most are detected during a physical examination. Larger epiglottis cysts can cause a foreign body sensation in the throat. Conservative treatment of epiglottic cysts is not effective, and if the cysts grow, it is better to choose surgery to solve them later, usually by laryngoscopic excision of epiglottic cysts, which can be done by electric knife, laser, or plasma knife. Congenital epiglottic cysts are common in infants and children and can present with symptoms such as dyspnea and cyanosis, requiring urgent treatment. It is recommended that laryngoscopy be done before surgery, and after surgery, care should be taken to prevent infection, cold liquid food should be given for 1-2 weeks after surgery, and bleeding in the throat should be observed.
