The main hazards of tonsillectomy are the possible short-term effects on children’s immunity, and in some patients, removal of the palatine tonsils may result in hyperplasia of the lingual tonsils, producing a foreign body sensation in the throat. But other than that, in patients with indications for tonsillectomy, the benefits of tonsillectomy generally outweigh the harms. The tonsils are the lymphoid tissue of the pharynx, and have a defensive role against upper and lower respiratory diseases. However, the immune function of the tonsils generally only has a greater role in adolescence, because the bone marrow function is not developed in this period, and the tonsils can produce more lymphocytes into the body fluids, to make up for the lack of lymphocyte demand. After the age of 18, the tonsils begin to atrophy and lose their defensive role. Therefore, tonsillectomy in adolescents should be performed in accordance with the indications for surgery and should not be performed lightly. Common indications for tonsillectomy include hypertrophy of tonsils affecting breathing, recurrent inflammation of tonsils causing nephritis, and benign and malignant tumors of tonsils, etc. At this time, the advantages of tonsillectomy outweigh the disadvantages. Currently, tonsillectomy is a minimally invasive procedure, which has improved the comfort of the surgery and postoperative bleeding rate. If you want to undergo tonsillectomy, it is recommended that you actively seek medical advice from your doctor, who will take into account the patient’s condition and the results of the examination to give you a professional opinion.
