Tonsillectomy in adults has certain indications for surgery. Under normal circumstances, tonsillectomy is not recommended for patients due to the presence of easy bleeding and dryness of the pharynx. However, if the indications are met, surgery can be performed to reduce tonsillar disease and possible complications.1. Benefit: Tonsillectomy can effectively improve the undesirable symptoms or prevent the reoccurrence of disease in the following groups of people, such as those with recurrent acute attacks of chronic tonsillitis or multiple peri-tonsillar abscesses; those with excessive tonsillar hypertrophy that hinders swallowing and respiratory functions and causes eating disorders or slurred speech. Those whose tonsils have become foci causing lesions in other organs due to chronic inflammation or are associated with lesions in neighboring organs; those with tonsillar keratosis and diphtheria with bacteria that have been ineffective with conservative treatment; those with benign tumors of the tonsils; those with unexplained long-term low-grade fever and the presence of chronic inflammation in the tonsils; 2. Cons: The process of tonsillectomy inevitably leads to tissue damage, such as mucosal tearing, edema, and subsequent release of inflammatory mediators such as prostaglandins and histamine, which further stimulate the glossopharyngeal and vagus nerves and cause pain. Postoperative pain may also occur if recovery is poor during the rehabilitation period. Therefore, postoperative rehabilitation care, such as paying attention to the hygienic condition of the affected area, taking care to avoid infection, eating a light diet after surgery, not eating spicy and stimulating foods, and going to the hospital for regular review, can prevent or improve the appearance of the above-mentioned drawbacks.
