The advantage of tonsil excision is mainly to solve the problem of recurrent chronic tonsillitis, the disadvantage is that it may affect the respiratory immunity. Tonsils belong to autoimmune organs and are prone to inflammation, especially in children, who are very prone to recurrent episodes of purulent tonsillitis during growth and development. Symptoms such as difficulty in breathing at night and wheezing occur after enlarged tonsils, and in severe cases, sleep may even be affected. Removal of the tonsils can effectively stop the recurrence of tonsillitis. However, since the tonsils belong to the lymphatic system, which has the function of immunization and prevention of disease, there is a possibility that the immunity of the respiratory system will be reduced after the removal of the tonsils. At the same time, there is a possibility of surgical complications, such as bleeding and infection. It is recommended to visit a regular medical institution, weigh the pros and cons, and follow the doctor’s instructions for treatment.
