After a patient has undergone a tonsillectomy, the tonsillitis itself will not recur because the tonsils have been removed intact. However, patients may experience different degrees of pain, dryness, burning, and foreign body sensation in the throat during the postoperative period, and such symptoms are often related to the acute and chronic inflammation of the throat mucosa. Patients also need to pay attention to strengthen the protection of the throat area, avoid excessive use of voice, avoid smoking, drinking, eating spicy and irritating food and other possible influences or causative factors to minimize the onset of acute and chronic inflammatory conditions in the throat.
