The number of days in the hospital for tonsillectomy depends on the patient’s condition and postoperative recovery, but in general tonsillectomy requires a hospital stay of five to seven days. In general, tonsillectomy requires 5 to 7 days of hospitalization. Those with postoperative infections and poor recovery will need to be hospitalized for longer. Tonsillectomy is usually performed 2 days prior to hospitalization with a comprehensive examination of the patient, such as routine blood tests, imaging tests, electronic laryngoscopy, etc., to determine the location of the lesion and the severity of the lesion, and at the same time, to assess whether the patient is able to tolerate the operation, the patient meets the conditions of the operation, the operation will be arranged on the third day. Observation is required for 2 to 3 days after tonsillectomy, mainly to observe whether there is localized bleeding and infection, and hospitalization will be required for a longer period of time if complications such as delayed bleeding and infection occur. After tonsillectomy in adults, due to recurrent episodes of chronic tonsillitis caused by peritonsillar vascular trapezoidal hyperplasia, the chance of postoperative bleeding is higher, more hospitalization for observation for a slightly longer period of time. Tonsillectomy usually requires 5 to 7 days of hospitalization, and the exact length of hospitalization needs to be decided according to the recovery.
