Chronic otitis media cholesteatoma type, i.e. middle ear cholesteatoma, the recovery time after surgery is related to the patient’s body resistance and whether or not the postoperative treatment is standardized, and usually one month after surgery. Surgery for middle ear cholesteatoma is mainly applicable to cases where the cholesteatoma has invaded the mucosa, bone and related functional structures of the middle ear. After surgery, if the patient’s body resistance is strong and the postoperative medication and review are standardized, the patient can usually recover in about one month. If the patient’s body resistance decreases and wound infection occurs, it will take a longer time to recover. If the patient is not feeling well after the middle ear cholesteatoma surgery, he/she should consult the hospital in time, and standardize the diagnosis and treatment after the systematic examination by the professional doctor.
