 Petrous bone cholesteatoma is located deep within the temporal bone and is therefore difficult to access surgically. The translabyrinthine approach results in a wide wound cavity, and whether the wound cavity should be treated as an open or closed cavity remains debatable. In this case report, we describe a 65-year-old man with petrous bone cholesteatoma with extensive dural exposure in whom we used a translabyrinthine approach and the wound cavity was left open. Good wound healing without any complications was observed 6 years after the operation.
