Epiglottis cyst belongs to a kind of pharyngeal cyst, which can occur in the epiglottic folds, epiglottic tongue surface and other loose mucosal tissues, and can be caused by chronic inflammation, mechanical stimulation, congenital developmental deformities and other reasons. Smaller cysts can be asymptomatic and do not cause abnormalities in the function of the surrounding tissues. As the swelling increases in size, it may manifest itself as a foreign body sensation in the pharynx, a feeling of swallowing obstruction, swallowing effort, and dyspnea, among other symptoms. For epiglottis cysts that cause obvious discomfort, the effective treatment is surgical resection. There are many methods of surgical removal of epiglottis cysts, including electrosurgical removal, radiofrequency ablation, low-temperature plasma removal, laser treatment and other measures. It is recommended to go to the hospital in time and follow the doctor’s instructions to standardize the treatment of epiglottis cyst.
