Localized pus flow after ear surgery is generally considered to be caused by an infection in the surgical wound, which depends on the severity of the inflammatory infection. If the infection is heavy, you need to use antibiotics for systemic application, and cephalosporin anti-inflammatory drugs are generally recommended. Then there is the need for localized ear cleaning with hydrogen peroxide, and after cleaning the pus, topical application of Telbital ear drops can be used. Do not eat spicy and stimulating foods during this period to avoid affecting the healing of the wound. If possible, local physical therapy can be done to promote the absorption of inflammation. If the infection is more serious and accompanied by headache, a brain CT should be done to prevent intracranial complications after surgery, and then treat the symptoms.
