Endoscopic optic nerve decompression: the Graz experience II

Recommendations for management of traumatic injuries to the optic nerve in the literature include expectant management, medical therapy, surgical treatment, and medical therapy combined with surgical decompression. Traditional surgical approaches to optic nerve decompression (OND) are a neurosurgical or craniotomy approach, extra nasal transethmoidal approach, transorbital approach, transantral approach, and intranasal microscopic approach. Since 1991 endonasal endoscopic decompression of the optic nerve has been the surgical approach of choice in patients requiring OND in the authors' hospital. The endoscopic method offers many advantages over the traditional approaches. Decreased morbidity, preservation of olfaction, rapid recovery time, more acceptable cosmetic results with no external scars, no risk of injury to the developing teeth in children and less operative stress in a patient who may have multisystem trauma are only some of the benefits associated with the endoscopic OND. The authors' technique of endonasal endoscopic approach to OND, medical management, and indications for surgery and the results of 51 patients undergoing this procedure are discussed
