If your doctor advises you that your ear needs surgery for otitis media, there are a few things to be prepared for: 1. Ear surgery, whether it is tympanic membrane repair or mastoid radical treatment, requires a long post-operative recovery time, not a wound that will be fine once the stitches are removed. Because tympanic membrane repair is a transplant, it takes time to establish new blood circulation to the transplanted tissue; mastoid radical treatment is to grow flesh on the bone surface, which is completely different from soft tissue healing, and requires more time to grow flesh buds on the bone surface first, and then crawl skin; 2. The inner ear also causes damage, even if the level of the doctor to restore completely normal hearing, in fact, is very difficult. This is because doctors are often dealing with patients who have accumulated many years of lesions to a certain degree; 3. It is also important to have the right expectation that no pus will flow after surgery. It is true that the vast majority of patients no longer have pus after surgery, but there are a small number of patients who will have pus and water flowing. This may be related to the underlying pathology of each individual. The auditory chain is an important element of middle ear hearing conduction, but it is also the area around it that is most heavily lesioned. Many surgeons consider preserving a portion of the patient’s normal auditory bone during surgery to ensure that the patient can still hear after surgery. This is a contradiction of going and staying, and if more is left, there is a risk of postoperative reflux. There is another situation that is difficult for the surgeon to handle. For example, if the lesion is adjacent to an important structure, such as around the facial nerve, we cannot sacrifice the function of the facial nerve in order to clean up some lesions. 4.Does facial paralysis occur frequently? With experienced doctors and hospitals, and with facial nerve monitoring during surgery, the incidence of facial palsy is now rare compared to the past.
