Abstract:
A 33-year-old immunocompetent man developed rapid visual loss and a third nerve palsy secondary to acute rhinosinusitis and intracranial abscess formation. Despite endoscopic drainage of the ethmoid and sphenoid sinuses and empiric broad-spectrum antibiotics, the patient experienced progressive visual and neurological decline and ultimately required craniotomy for drainage of an optic apparatus abscess. Although odontogenic sinusitis rarely results in abscess formation of the visual pathways, early recognition and immediate treatment is imperative to decrease the risk of profound and permanent visual impairment.

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...
