Cholesteatoma-type otitis media, i.e. middle ear cholesteatoma, should follow the doctor’s instructions to observe the condition, regular rechecking, reasonable diet, ensuring clean and dry ears, and guarding against respiratory infections, etc. After surgery, the patient should follow the doctor’s instructions to observe the condition and recheck regularly. 1. Observe the condition and review regularly. Observe the ear canal in daily life to see if there is fluid or pus flow, or if the hearing deteriorates, or if there is dizziness or tinnitus, etc. If there are corresponding symptoms, it is necessary to consult the doctor in time; it is recommended to follow the doctor’s instructions to review the condition regularly after the surgery until there is no cholesteatoma remaining, no infection, and the tympanic membrane is healed well. 2. Reasonable diet. Generally, it is forbidden to eat and drink within 6 hours after the surgery; after 6 hours, you can eat fluids, and after 1 day, you can eat soft food, such as congee, noodles, etc. according to the recovery situation. 3. Ensure that the ear is clean and dry. You need to wear waterproof earplugs, etc. when bathing to prevent water from entering the ear canal, thus keeping the ear canal dry; you cannot clean the affected ear canal by yourself, and don’t use medicine drops into the ear canal without authorization. For surgical incisions, care should be taken to keep them clean and dry, especially when washing hair or bathing. 4. Prevent respiratory infections. Make sure you have a regular routine, exercise moderately to strengthen your body, and try to avoid catching a cold, as sneezing and blowing your nose when you have a cold may cause pressure to damage the eardrum. 5. Don’t travel by airplane within 3 months after the surgery, in order to avoid adverse effects on the repair of the eardrum or the artificial hearing bone. After the middle ear cholesteatoma surgery, you should strictly follow the precautions given by the doctor and go to the hospital as soon as possible if you have any discomfort in order to avoid any adverse consequences.
