Abstract:
Aneurysmal bone cyst (ABC) is an uncommon lesion of the temporal bone (TB), with only 20 cases reported. Facial paralysis is a rare complication (2 cases); however, no cases have been reported with preoperative reversal of paralysis. We report a 60-year-old man with a history of remote head trauma, who presented with serious otitis media and right hemifacial paralysis, which resolved with nonsurgical therapeutic measures. Magnetic resonance imaging and computed tomography showed a destructive and expansile lesion of the TB. The lesion was surgically removed, and ABC was diagnosed histologically. The patient had an uneventful recovery and demonstrated no recurrence at 1 year of follow-up. This report presents an unusual presentation of ABC in the TB, with a review of the clinical, radiological, pathological, and therapeutic features of this entity.

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...
Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
