Abstract:
Fibrous dysplasia is an uncommon benign bone disorder of unknown origin. It rarely affects the temporal bone. We report a case of fibrous dysplasia of the temporal bone with cholesteatoma in the external auditory canal, the first complaint of which was left otorrhea. Fibrous dysplasia invaded the external ear canal, stenosis of which causes a cholesteatoma. Mastoidectomy, tympanoplasty, and meatoplasty were performed. We discuss the characteristics of this condition, its differential diagnosis and its treatment.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
