What is mastoid obliteration?
Mastoid obliteration is commonly performed to reduce the size of mastoidectomy cavity following canal wall-down tympanomastoidectomy for chronic otitis media. The indications and techniques for mastoid obliteration as well as total tympanomastoid obliteration will be reviewed.
What are the types of mastoidectomy?
Broadly, there are two major types of mastoidectomy: canal wall up and canal wall down. [1] Canal wall up mastoidectomy preserves the posterior bony external auditory canal, which separates the ear canal from the mastoid cavity.

The indications and techniques for mastoid obliteration as well as total tympanomastoid obliteration will be reviewed. The vast majority of obliteration techniques consist of either local flaps or free grafts (bone, cartilage, fat, hydroxyapatite). The radiographic and histopathologic features of mastoid obliteration will also be reviewed.
What is the difference between primary and secondary mastoid obliteration?
Patients with primary cholesteatoma who had mastoidectomy and mastoid obliteration were defined as having primary obliteration. Secondary obliterations were those with an existing canal wall down mastoidectomy who were having otorrhoea and who had revision mastoidectomy and mastoid obliteration.
What are the possible complications of a mastoidectomy?
A mastoid cavity resulting from a canal wall down mastoidectomy can result in major morbidity for patients due to chronic otorrhea and infection, difficulty with hearing aids and vertigo with temperature changes. Mastoid obliteration with reconstruction of the bony external ear canal recreates the normal anatomy to avoid such morbidity.
What is mastoid Obliteration with reconstruction of the external ear canal?
