A cholesteatoma is a sac of infection behind the ear drum into the middle ear and mastoid. It results in a chronic, foul smelling ear discharge, can damage delicate structures of the ear and cause complications of the.
Mastoidectomy is an ear surgery performed to remove diseased mastoid air cells as a result of an ear infection. There are different types of mastoidectomy:
Simple mastoidectomy: ENT surgeon opens mastoid bone and removes infected air cells.
Radical Mastoidectomy: Infected air cells along with ear drum and middle ear structures are removed.
Modified Radical mastoidectomy: Only disease middle ear bones are removed and ear drum is rebuilt.
If mastoid infection or cholesteatoma is untreated it could destroy hearing-deafness, balance organs-dizziness and facial nerve which can cause paralysis of face. It can cause meningitis & brain infections. Removing cholesteatoma is for safety to prevent spread of further infection and improve hearing in the ear. A mastoidectomy may also be done to put a cochlear implant for profound hearing loss.
Hospital stay for at least one night may be required. Stiches are removed after 7 days. In open cavity mastoidectomy cavity need regular care in ENT clinic. You can wash hair after one week just keep water away from operated ear.Swimming can be done after 4-6 weeks after the operation.
