Tonsils are an immune organ of the body and are more important in childhood. As the whole body immune system of children is not yet complete, if removed, it will have a short term effect on the immunity of children. Therefore, tonsillectomy is not suitable for everyone, but is only considered under certain circumstances. Tonsillectomy requires certain surgical indications, and in healthy conditions, tonsils cannot be removed. Tonsillectomy can only be considered when there are indications for surgery. When the tonsils are repeatedly inflamed and purulent, more than 3-5 times a year, you can consider removing the tonsils because, in this case, there is chronic inflammation of the tonsils, which may have adverse effects on other systems of the body if they are repeatedly inflamed in the long run. In children, if the symptoms are not recurrent inflammation and suppuration, but sleep snoring and breath-holding, the enlarged tonsils must also be removed to avoid affecting the sleep of the affected child, leading to lack of oxygen during sleep and open-mouth breathing, which affects the development of the face, body and intelligence. In addition, tonsillar keratosis and benign and malignant tumors of the tonsils are also considered for removal of diseased tonsils. In the case of malignant tumors, some tonsils do not need to be removed but are treated with a combination of radiation therapy and chemotherapy. For children, the greatest danger of tonsil removal is that it affects the immunity of the body, and for patients with tonsils that are indicated for surgery, tonsillectomy is a necessary treatment
