The diagnosis and treatment of petrous bone cholesteatoma is a challenge to aural surgeons. Seven patients with extensive petrous bone cholesteatomas which invaded the labyrinth and fallopian canal are presented. These cholesteatomas originated as secondary to acquired lesions. The cases were evaluated according to the clinical features, the intraoperative findings, the radiological findings, and the surgical approaches. In this series, six patients presented with facial paralysis associated with profound or total deafness. The transtemporal lateral approach was used in all the cases. Acute facial nerve palsy or facial nerve pareses progressing to palsy in patients with chronic ear disease should be studied radiographically for petrous bone cholesteatoma, even if there is no physical evidence of cholesteatoma.

D010579	Petrous Bone	The dense rock-like part of temporal bone that contains the INNER EAR. Petrous bone is located at the base of the skull. Sometimes it is combined with the MASTOID PROCESS and called petromastoid part of temporal bone.	Petrous Apex,Petrous Pyramid,Bone, Petrous,Petrous Bones
D001847	Bone Diseases	Diseases of BONES.	Bone Disease,Disease, Bone,Diseases, Bone
D002781	Cholesteatoma	A non-neoplastic mass of keratin-producing squamous EPITHELIUM, frequently occurring in the MENINGES; bones of the skull, and most commonly in the MIDDLE EAR and MASTOID region. Cholesteatoma can be congenital or acquired. Cholesteatoma is not a tumor nor is it associated with high CHOLESTEROL.	Cholesteatomas
D005158	Facial Paralysis	Severe or complete loss of facial muscle motor function. This condition may result from central or peripheral lesions. Damage to CNS motor pathways from the cerebral cortex to the facial nuclei in the pons leads to facial weakness that generally spares the forehead muscles. FACIAL NERVE DISEASES generally results in generalized hemifacial weakness. NEUROMUSCULAR JUNCTION DISEASES and MUSCULAR DISEASES may also cause facial paralysis or paresis.
