In this article we describe the surgical management of petrous bone cholesteatoma, a rare form of an epidermoid cyst growing medially into the petrous part of the temporal bone. In our series of 5 patients, high resolution Computerized Tomography (CT) played an essential role in the diagnosis of this pathological entity. CT was also important in planning for the surgical access to this intricate part of the temporal bone. In all cases we performed a subtotal petrosectomy with skeletonization of the facial nerve bony canal to preserve the facial nerve function. We were able to remove totally the medially growing cholesteatoma with low morbidity.
