Intratympanic cholesteatoma.

Cholesteatomas occurring behind an intact TM are relatively unusual, and intratympanic keratomas are even less common. This article presents the case of a Baffin Zone Inuit gentleman with an intratympanic cholesteatoma confined to the membranous portion of his TM. Although it is generally accepted that many native populations, including the Inuit, demonstrate an elevated preponderance of aural disease, cholesteatoma formation, particularly within the TM, in an individual from this area of the high Arctic is extremely rare.
