Postoperative precautions for epiglottis cyst include diet, oral hygiene and anti-inflammatory treatment. 1. Diet: In the early stage after cyst surgery, you should pay attention to eating some warm and cool fluids, and gradually transition to soft fluids in the later stage. It is recommended not to eat too hard or too hot food within one month, so as not to cause bleeding from the wound and affect the healing of the wound. 2. Oral hygiene: Because of the fresh wound after cyst removal, if it triggers local infection in the pharyngeal cavity, it will easily lead to wound ulceration and bleeding. Therefore, it is necessary to pay attention to maintaining oral hygiene and rinse the mouth before going to bed and after meals to avoid bacterial infection. 3. Anti-inflammatory treatment: Because the pharyngeal cavity belongs to class II incision after cyst surgery, it is easy to suffer from bacterial infection, so it is necessary to carry out anti-inflammatory treatment after surgery, and antibiotics can be used for anti-inflammatory treatment, preferred to cephalosporins and penicillins, such as cefuroxime, amoxicillin and so on. It is recommended that the patient actively cooperate with the doctor under the guidance of the doctor to do rehabilitation therapy, if there is discomfort, timely communication with the doctor to deal with.
