Mastoiditis is a bacterial infection of the mastoid air cells surrounding the inner and middle ear. The mastoid bone, which is full of these air cells, is part of the temporal bone of the skull.
Is mastoiditis surgery serious?
Complications of a mastoidectomy can include: facial nerve paralysis or weakness, which is a rare complication caused by facial nerve injury. sensorineural hearing loss, which is a type of inner ear hearing loss. dizziness or vertigo, which may persist for several days.
What is right Otomastoiditis?
Mastoiditis is an infection of the bony air cells in the mastoid bone, located just behind the ear. It is rarely seen today because of the use of antibiotics to treat ear infections. This child has noticeable swelling and redness behind his right ear because of mastoiditis.
What is chronic Otomastoiditis?

It should be considered a separate entity from acute otomastoiditis.
What is bilateral mastoiditis?
Mastoiditis is a serious infection in the mastoid process, which is the hard, prominent bone just behind and under the ear. Ear infections that people fail to treat cause most cases of mastoiditis. The condition is rare but can become life-threatening without treatment.

What is the pathophysiology of otomastoiditis?
Otomastoiditis, or more simply inflammation of the mastoid air cells, can be divided into two distinct entities: acute otomastoiditis: usually due to bacterial infection.
What is the relationship between cholesteatoma and chronic erosive otitis media?
However, chronic erosive otitis media and cholesteatoma commonly coexist; the main role of imaging is to show the extent of disease rather than to “make a diagnosis.” Cholesteatoma may also obstruct the mastoid antrum and may promote infection or inflammation in the mastoid ( Fig. 111.2C ).
Can cholesteatoma coexist with granulation tissue in the ear?
Recall that cholesteatoma may coexist with granulation tissue and that loculated fluid in the middle ear or mastoid will not enhance.
Which soft tissue changes are characteristic of otitis media (OM)?
On the left (A, B), soft tissue changes are seen in the middle ear cavity in a patient with long-standing otitis media. Secondary to the inflammation, fibro-osseous material has formed in the epitympanum, resulting in fixation of the malleal head to the epitympanic tegmen.
