If there is a feeling of obstruction under the throat, one should consider whether it is caused by epiglottis cyst, reflux pharyngitis or esophageal cancer, and the treatment mainly includes medication and surgery. 1. Epiglottis cyst: It is a cyst formed by mucus retention due to obstruction of mucous gland ducts of epiglottis mucosa. It may cause discomfort, foreign body sensation and blockage in the larynx. The main treatment method is to support laryngoscopic epiglottic cyst excision. 2. Reflux pharyngolaryngitis: gastric contents reflux into the throat, stimulating the mucous membrane of the throat, causing congestion and swelling of the mucous membrane, so there will be a sense of blockage. Treatment can apply acid-suppressing drug Omeprazole, gastric power-boosting drug Domperidone and so on. 3. Esophageal cancer: esophageal cancer leads to rigidity of esophageal movement, causing narrowing of lumen and feeling of obstruction when swallowing. Treatment should be surgical resection of tumor and supplemented by radiotherapy. If the above symptoms occur, one should consult doctor in time to find out the cause of the disease and treat the cause.
