Definition and Types of Mastoidectomy

In this article, we will discuss the Definition and Types of Mastoidectomy. So, let’s get started.


Mastoidectomy is a surgical procedure performed to remove the mastoid air cells. It can be done as part of treatment for mastoiditis, chronic suppurative otitis media or cholesteatoma or for access to the middle ear.


Simple mastoidectomy: This aims at draining mastoid air cells by a post ant app. It does not disturb the structure and function of middle ear, hence the hearing is unaffected.

Radical mastoidectomy: In this operation the mastoid, the middle ear and external auditory canal are converted into a single cavity by lowering the wall between the mastoid and external ear and by the removal of the ruminants of the ear drum, malleus, and incus the stapes is not removed as the labyrinth gets exposed and may be damaged. Conductive deafness may be a sequale of this operation.

Modified radical mastoidectomy: The mastoid, attic, and external ear are converted into a single cavity without touching the mesotympanum. Hearing is not affected.
