Let’s first understand what tonsils are all about. The human voice is rich in lymphoid tissue, the largest pair of which is called tonsils. The tonsils are an immune organ of the human body, which can defend against various disease-causing microorganisms that invade the body and play a certain role in fighting diseases, especially before the age of 4 years old when the immune function is strong and shows compensatory hypertrophy, becoming an important line of defense against diseases. Tonsillitis is divided into two categories: acute and chronic. When the acute attack of tonsillitis is manifested as high fever, chills , headache, general weakness, throat pain is especially obvious, especially when swallowing food pain is increased, some children therefore do not eat food, and even do not drink water. Some children may not eat or even drink water because of this. Other children may have a high fever that causes a seizure. On examination, the tonsils are visibly congested and swollen, with grayish or yellowish-white pus spots on the surface, which become a layer of pus moss if fused into a sheet, along with enlarged and painful submandibular lymph nodes. After antibiotics such as penicillin, cephalosporin, erythromycin and other symptomatic treatments, it heals in about 7-10 days. Some children often have recurrent episodes of acute tonsillitis, 4-5 times a year, or even once a month, resulting in chronic tonsillitis. Chronic tonsillitis is mostly caused by repeated attacks of acute tonsillitis or local inflammation that does not heal. Examination reveals enlarged tonsils, enlarged crypt orifice, and yellowish-white secretions or food boluses can be seen in the crypt orifice. A lymph node the size of a soybean or a date palm can be felt under the jaw, without obvious tenderness. So what kind of tonsils should be removed? 1.Chronic tonsillitis is often recurrent, with inflammation more than 4-5 times in a year. 2.Have had peri-tonsillitis and peri-tonsillar abscesses. 3.Tonsils are excessively enlarged and have affected breathing and sleep. 4. Focal tonsillitis. This means that the tonsillitis is complicated by nephritis, rheumatic heart disease, myocarditis and rheumatoid arthritis. Research in the last decade or so has found that psoriasis is also closely related to tonsillitis. This kind of patients can have their tonsils removed during the stable period. 5, unexplained long-term low fever, tonsils themselves have chronic inflammation, in the exclusion of other medical diseases can be removed tonsils. 6.Tonsil keratosis or stones, polypoid hyperplasia, cysts and other benign masses on them. When it is decided to have a tonsillectomy, when is the most appropriate time? As long as the health condition is good in the near future, no cold, fever, cough can be operated, or 10 days after the tonsillitis is healed, or focal tonsillitis in the stable period of the disease can be operated.
