Usually this can be estimated at the time the operation is planned. Generally, the main goal of surgery is a clean, safe ear, free of infection. Perforations in the eardrum can usually be repaired successfully. Hearing loss can often be improved. If an active infection is present, a smaller operation in the future may be the best means of improving hearing.
Surgery is generally safe and well tolerated.
However, as with any operation, there are risks as well as benefits. This is particularly true when cholesteatoma is present. The first post-op appointment is 2 weeks after the surgery. At this time, gauze packing is removed from the ear. Follow-up visits are made about once a week thereafter until the ear is completely healed, usually 6 weeks or so.
