The technique of tonsillectomy for enlarged tonsils in children has gradually matured, and the chance of risk is generally low. Localized pain and a runny nose may occur after surgery, and a very small number of people may vomit or even suffocate after surgery due to the side effects of anesthesia medication. Enlarged tonsils are usually caused by chronic inflammatory stimulation around the local area, or by personal eating disorders or over-nutrition, resulting in enlarged tonsils and causing related discomfort. Surgery can be used when conservative treatment is not effective in some children. 1. If traditional surgery is chosen, the patient will have obvious pain, bleeding and runny nose after the surgery, which are common after the surgery. 2. In traditional surgery, only a very small number of patients will be induced to vomit and other uncomfortable symptoms due to the side effects of anesthesia drugs. If preventive measures are not taken in time, the vomit will be retained in the throat or refluxed into the trachea, which will cause the patient to suffocate. 3. With the development of medical technology, now the surgical method of low-temperature plasma radiofrequency ablation treatment, has the advantages of simple operation, less bleeding and so on. After the removal of tonsil hypertrophy in children, due to individual variability, then the postoperative risk rate can not be generalized, it is recommended to consult a professional doctor.
