A mastoidectomy is done to remove diseased mastoid air cells. These compartments sit in a dull space in the skull, behind the ear. The diseased cells are habitually the result of an ear infection that has supper into the skull.
Sometimes the infection feasts onto the temporal bone. If this befalls, parts of the bone may need to be detached. This results in hearing harm.
simple mastoidectomy: the surgeon opens the mastoid jawbone, removes the infected air cells, and sanitations the middle ear
radical mastoidectomy: the surgeon may remove the membrane and middle ear structures. Sometimes a skin graft is placed in the central ear
modified radical mastoidectomy: this is a less simple form of radical mastoidectomy. Not all middle ear bones are aloof and the membrane is rebuilt.
