Congenital epiglottis cysts are more common in clinical practice and include both congenital and acquired types of epiglottis cysts, with differences in the causes of their formation. Throat epiglottis cyst is a benign disease, generally growing slowly, and most of them are found during physical examination.1. Congenital type epiglottis cyst: during the developmental period, due to abnormal development, the laryngeal bursa is enlarged and mucus is not secreted, and the early secretion is very little and can be absorbed by itself. However, if the laryngeal bursa continues to expand, more and more secretions cannot be discharged, and cyst-like substances are formed on the epiglottis over time, forming laryngeal epiglottic cysts, which can be single or multiple; 2. Acquired epiglottic cysts: mainly due to chronic inflammatory stimulation, trauma, mechanical stimulation, improper diet, etc., which make inflammation and secretions appear in the glands of the epiglottic mucosa. If the secretion cannot be discharged normally, it will gradually swell to form a laryngeal epiglottic cyst with a single or multiple cysts around the epiglottis, and the cyst skin is wrapped with a cloud of cystic fluid. Chronic inflammation long-term stimulation, glandular secretions more and more, excretion is not out, the cyst around the epiglottis will also grow bigger and bigger, and eventually affect breathing and swallowing. If the patient has a large cyst in the epiglottis, a foreign body sensation in the throat and a feeling of pressure, surgery is required. At present, the laryngoscopic method of low-temperature plasma radiofrequency ablation is mostly used to support the removal of laryngeal epiglottis cysts. At the same time, we should pay attention in our daily life, try to eat less spicy and stimulating food, avoid smoking and alcohol.
