Case Discussion

Cholesteatoma consists of the presence of keratinized squamous epithelium formed and accumulated in the middle ear or in any other part of the temporal bone, so it can also be located in the external auditory canal, mastoids, and petrous bone.

They're rare but, if left untreated, they can damage the delicate structures inside your ear that are essential for hearing and balance.
