Abstract
The endoscopic endonasal trans-sphenoidal approach can decompress the traumatized and swollen optic nerve without brain retraction. Three cases of traumatic optic neuropathy (TON) were treated by this endoscopic approach. We performed 58 endoscopic endonasal trans-sphenoidal approaches in 52 patients between April 2006 and December 2007. Three patients, 2 men and a woman aged 42-66 years, with TON were treated by endoscopic endonasal trans-sphenoidal optic nerve decompression. Adequate decompression of the optic canal was observed in all three patients. Two experienced improved visual function, but the third did not. No surgical complications were observed in any patient. We were able to reach the optic canal above the opticocarotid recess near the orbit. Endoscopic endonasal trans-sphenoidal optic canal decompression using a navigation system may be a safe and effective surgical strategy in carefully selected patients with TON.
