Abstract
Traumatic optic neuropathy complicates approximately 2% of closed head injuries. Although sudden blindness is an infrequent presenting symptom after craniofacial trauma, its consequences are devastating for the patient, thus requiring prompt recognition. Although a uniform approach to the management of traumatic optic neuropathy is not currently available in the literature, the options for therapy consist of observation or a combination of systemic steroids and/or surgical decompression of the optic nerve by intracranial or extracranial approaches. In this article, 12 optic nerve specimens in cadavers were dissected, with anatomic landmarks delineated and measurements taken from the anterior nasal spine. The transnasal approach using endoscopic surgical technique is discussed in this article. Endoscopic optic nerve decompression can be offered as a method of treatment for traumatic optic neuropathy.
