This patient was operated for Mastoidectomy for Cholesteatoma disease.The ossicular chain was intact.
An endoscopy was done to check for any remnant disease preserving the Ossicular chain and the hearing ability.
A mastoidectomy is performed to remove infected mastoid air cells resulting from ear infections, such as mastoiditis or chronic otitis, or by inflammatory disease of the middle ear (cholesteatoma). The mastoid air cells are open spaces containing air that are located throughout the mastoid bone, the prominent bone located behind the ear that projects from the temporal bone of the skull.
Sometimes the infection spreads onto the temporal bone. If this occurs, parts of the bone may need to be removed. This results in hearing loss.
There are several types of mastoidectomy.
Simple mastoidectomy: the surgeon opens the mastoid bone, removes the infected air cells, and drains the middle ear
Radical mastoidectomy: the surgeon may remove the eardrum and middle ear structures. Sometimes a skin graft is placed in the middle ear.
Modified radical mastoidectomy: this is a less severe form of radical mastoidectomy.
Not all middle ear bones are removed and the eardrum is rebuilt.
Some hearing loss is to be expected with radical and modified radical mastoidectomy.
