Surgery is not mandatory for epiglottis cysts. Smaller epiglottis cysts with no obvious symptoms can be left untreated for the time being, and can be reviewed regularly. Surgery is an option for epiglottis cysts that cause clinical symptoms. An epiglottis cyst is a cystic swelling formed when the mucus ducts of the epiglottis are obstructed, resulting in retention of mucus. Epiglottis cysts usually have no obvious symptoms and are usually found by chance during a throat examination. If the epiglottis cyst is large in size, corresponding symptoms will appear, such as foreign body sensation in the pharynx, and some patients will have mild difficulty in swallowing, irritating cough and other symptoms. If obvious symptoms appear, you need to go to the hospital in time. If the patient develops an infection, the infection needs to be controlled by antibiotic drugs first, such as ceftriaxone. After the infection is controlled, it can be treated by surgery, such as cystectomy. Drugs should be used under the guidance of a doctor.
