Generally the best age for tonsillectomy is after 4 years of age, but surgical intervention can be performed as early as possible if there is an indication for surgery. As an immune organ, the tonsils have their own physiological functions. Especially in children, the tonsils have an important protective role for the organism. Arbitrary removal of the tonsils will result in loss of local immune response and even immune surveillance disorders. Therefore, the indications must be strictly controlled. This type of surgery is currently performed under general anesthesia, due to anesthesia safety considerations, it is recommended that tonsillectomy should be performed after the age of 4 years, when the risk of anesthesia will be reduced relative to younger children. However, age is not an absolute contraindication to tonsillectomy, if tonsil hypertrophy causes obvious symptoms (such as snoring, open-mouth breathing, otitis media, poor diet, chronic runny nose, etc.), or affects the child’s daily life and after medication is ineffective can be as early as possible for surgical intervention. If the child is diagnosed with enlarged tonsils, it is recommended to actively seek medical advice from a specialist who will integrate the patient’s condition and physical status to give advice on whether surgery is needed and to receive standardized treatment.
