There are indications for tonsillectomy. Tonsillectomy is required in the following cases: 1. Recurrent tonsillar inflammation or the presence of peri-tonsillar abscesses. 2. Benign tumors on the tonsils, which need to be removed along with the tumors and tonsils. 3. Enlarged tonsils, which affect swallowing function or affect breathing, causing snoring during sleep. 4. Tonsils become a lesion and cause certain systemic complications, such as acute nephritis, myocarditis, arthritis, etc. Except for the above cases, tonsillectomy is not recommended because tonsils have immune function and have a certain effect on the body’s resistance to diseases. At present, tonsillectomy is mostly performed by plasma tonsillectomy, which is minimally invasive and has the advantages of less damage, less bleeding and less pain.
