An operation to repair the perforation is called a ‘myringoplasty’. The benefits of closing a perforation include prevention of water entering the middle ear, which could cause ear infection. Repairing the hole means that you should get fewer ear infections. It may result in improved hearing, but repairing the eardrum alone seldom leads to great improvement in hearing. If the hole in the eardrum has only just occurred, no treatment may be required. You should discuss with your surgeon whether to wait and see, or have surgery now.
You may change your mind about the operation at any time, and signing a consent form does not mean that you have to have the operation. If you would like to have a second opinion about the treatment, you can ask your specialist. He or she will not mind arranging this for you. You may wish to ask your own GP to arrange a second opinion with another specialist.
A mastoidectomy is an operation to remove an infection or skin growth behind your eardrum together with the surrounding (mastoid) bone.
Mastoid surgery is performed when infections in the middle ear spread to the mastoid cavity. Commonly a pocket of skin develops on the ear drum and may invade the middle ear and subsequently the mastoid. This may cause recurrent ear discharge. The cholesteatoma may also invade the ossicles (3 bones in the ear that are involved in hearing), causing hearing loss. Other important structures like the brain, nerve that supplies the muscles of the face and blood vessels run close by and hence the cholesteatoma must be removed to prevent these structures from being eroded. The operation to do this is known as a mastoidectomy
