Abstract

Labyrinthine fistula caused by cholesteatoma can make various complications according to the site of the lesion. The lateral canal, superior canal ampulla, posterior canal and promontory of the cochlea are the common areas of fistulization. However, invasion into the cochlea or internal auditory canal (IAC) is very rare. We have experienced a case of cholesteatoma extending into the cochlea and IAC, which was successfully treated via the transotic approach. Herein we report this case with a review of literature
