Epiglottis cysts usually have no obvious symptoms when they are relatively small, and if they are more serious, they may lead to pharyngeal discomfort, swallowing obstruction and other symptoms. Epiglottis cyst is a relatively common benign tumor, which may be caused by congenital developmental malformation of the larynx, or may be caused by other reasons. If the epiglottis cyst is relatively small, there is usually no obvious manifestation, and most of the time, it is found during laryngeal examination. If the epiglottis cyst is heavy, or causes pressure on the local tissues, it will lead to obvious discomfort in the pharynx, such as a sense of foreign body in the pharynx or even a sense of obstruction, etc. As the volume of the epiglottis cyst gradually increases, it may also cause blockage of the airway, which may lead to respiratory difficulties. If epiglottis cysts cause obvious discomfort, it is necessary to go to the hospital in a timely manner, cooperate with the doctor to take surgical treatment, and pay attention to the follow-up examination after the operation.
