There are strict indications for tonsil removal, i.e., the tonsils will only be removed due to the need of the condition, and the advantages of removal outweigh the disadvantages. Possible harms include dry throat, foreign body sensation in the throat, decreased immunity in the throat, etc., but the chance of occurrence varies from person to person. Even if there is postoperative discomfort in the throat, the symptoms will gradually subside after a period of recovery. 1. There are a large number of mucous glands on the surface of tonsil tissues. If the tonsils are removed, the mucous gland tissues in the oropharynx will be reduced, which will reduce the mucous secretion in the pharynx and produce the phenomenon of dry throat. 2. When tonsil tissue needs to be removed, most of them have obvious inflammation. When tonsils are removed, fibrous scar tissue may form in the pharynx, and the lymphatic tissue of lingual tonsils and pharynx will proliferate, triggering the phenomenon of foreign body sensation. 3. Tonsil tissue is the lymphatic organ of the oropharynx, after tonsil tissue, the lymphatic organ of the oropharynx may be reduced, leading to a short-term decline in the immune function of the oropharynx, after a period of time can be compensated for the immune function through other parts of the body’s lymphatic organs. If you feel abnormal after tonsillectomy, you can go to the ENT department to clarify the cause of the disease and follow the doctor’s instructions to standardize the treatment.
