The consequences of untreated epiglottic cysts depend on the severity of the patient’s condition and may continue to increase in size. An epiglottic cyst is a cystic mass formed by the obstruction of the mucus ducts of the epiglottis, resulting in mucus retention. Whether a cyst requires treatment depends on the size of the cyst and the symptoms it causes, as determined by a feasible physical examination and electronic laryngoscopy. If the epiglottis cyst is small and does not cause any symptoms after examination by the doctor, it can be left untreated for the time being and should be reviewed regularly. If the epiglottic cyst is larger and has symptoms such as pharyngeal discomfort and foreign body sensation, it should be actively treated. If it continues to be untreated, it may lead to aggravation of the cyst and continue to increase in size causing a significant foreign body sensation when eating or swallowing, and if the cyst wall is thin at this time, it may cause the outflow of cystic fluid and lead to choking and coughing. Larger cysts blocking the vocal canal may cause breathing difficulties, and repeated inflammation without treatment may lead to acute epiglottitis, which may cause breathing difficulties or even asphyxia in severe cases. Patients can temporarily observe the epiglottis cyst after discovery, if the symptoms continue to not improve, feasible local surgical treatment, also feasible laser, plasma knife and other elimination, postoperative antibiotics to avoid infection, but also use low-dose hormone nebulization to relieve symptoms.
