1. Avoid excessive fatigue, colds or upper respiratory tract infections as much as possible. 2. Do not blow your nose for about a week after surgery. Any nasal secretions retained in the nasal cavity should be aspirated back and coughed up through the mouth to avoid causing ear infections. If you need to sneeze, be sure to open your mouth and never pinch your nose to stop the sneezing, and do not play instruments that use airflow for 3 weeks. 3. You may wash your hair 2 days after the procedure while a cotton ball coated with petroleum jelly is placed at the opening of the external ear canal to ensure a waterproof seal. We usually use intradermal sutures that do not require removal of stitches. The tape behind the ear can be removed one week after surgery and the outer ear cleaned with a towel moistened with warm water, but do not allow water to enter the outer ear canal for at least 3 weeks. 4. After discharge from the hospital until the first follow-up visit, use antibiotic ear drops twice a day, with the affected ear facing upwards, and keep them for 5 to 10 minutes to facilitate the absorption of the solution. Any liquid or gel-like material flowing from the external ear canal can be wiped away with a clean dry cotton ball. 5. Cotton balls should only be placed in the external ear canal during the daytime in dusty environments, and at night in order to prevent the exudate from contaminating the pillow. The cotton balls in the ear canal opening are contaminated (soaked) that is replaced. The exudate should be reddish-brown to brown at first and usually becomes clear or disappears within 3 to 6 weeks. The ear canal is routinely filled with gelatin sponges and the exudate will turn it pink and jelly-like. 6.If your doctor prescribes antibiotics, please purchase the medication as soon as possible and follow the doctor’s instructions. 7. If any of the following occur, contact your supervisor or primary surgeon: 1) persistent bleeding, or persistent fever, or persistent pain or vertigo 2) purulent discharge (foul odor) from the ear canal or incision 3) rash around the ear or incision 4) facial paralysis 8. Do not be overly concerned about your hearing for one month after surgery, as it will take time for the filling material in the tympanic cavity and ear canal to be removed. You may hear the sound of running water in your ear for a few weeks, this is normal and please do not be anxious. 9. Numbness in the ear and possibly a change in taste may occur after surgery, and this change usually resolves gradually. 10.If the artificial auditory tuberosity is used and not prevented from falling off or shifting, you cannot participate in physical activities such as jumping and running for six months. The implanted titanium auditory tuberosity is safe for MRI scanning. 11. Regular follow-up cleaning is required after surgery. The first time is usually 3-4 weeks after surgery.
