Children are physically fragile, and tonsillectomy is not recommended for children under 4 years of age without special circumstances. After 4 years of age, tonsillectomy can be performed with clear indications and no obvious contraindications. Indications for tonsil surgery include moderately to severely enlarged tonsils affecting physiologic function, and enlarged tonsils causing severe obstructive sleep apnea. Repeated tonsillar infection and inflammation causing systemic symptoms, repeated tonsillar inflammation causing glomerulonephritis. With these indications, resection can be considered. However, attention should be paid to the contraindications. It is important to pay attention to whether the inflammation is under control, whether there is any disorder in the hematopoietic and coagulation system, and whether there is any systemic disease. Tonsillectomy can be performed after exclusion. Tonsil surgery in children is best performed after the age of 4. There are no overly detailed rules, but it depends on the condition and individual circumstances, and is under the guidance of the doctor.
