Description of the ProcedureThe type of surgical procedure will depend on your condition. Factors such as hearing status and the size and location of the tumor will be considered. One of the following surgical methods will be selected:TranslabyrinthineThis approach is often used when you already have significant hearing loss. The mastoid bone in the skull and bone in the inner ear will be removed. This allows access to the ear canal and the tumor.Retrosigmoid/Sub-occipitalAn opening will be made in the skull behind the ear. It makes it easier to see and protect the nerves during surgery.Middle FossaThe tumor will be removed from the upper surface of the ear canal. This approach is used when there is a good chance that hearing may be maintained.
