Medications

-
Epitympanic (attic) cholesteatoma. This is a typical primary acquired cholesteatoma in its earliest stages.
-
A large epitympanic (attic) cholesteatoma that is much more advanced than the lesion in the previous image.
-
A large cholesteatoma. No landmarks are visible, which typically is the case with advanced cholesteatomas.
-
A cholesteatoma with a white mass can be seen behind an intact drum.
-
An unenhanced computed tomography (CT) scan demonstrating that the posterior canal wall has been eroded and the external auditory canal has filled with cholesteatoma, pus, and debris. Surprisingly, the middle ear appears relatively free of disease, a characteristic of primary acquired cholesteatomas.
-
The photo exhibits a large meatoplasty performed as part of an open cavity (canal wall–down) mastoidectomy. A similar meatoplasty usually is necessary if a clean, dry, problem-free cavity is to be maintained.
-
A typical audiogram demonstrating bilateral conductive hearing loss, which may be observed in an individual with a cholesteatoma.
-
Advanced cholesteatoma with exposure of posterior cranial fossa dura.
