  • Abstract
  • Look Inside

 Microscopic endonasal decompression of the optic nerve was performed in patients with optic nerve injuries. After widely opening the ethmoid and sphenoid cavity along the orbital funnel, we could detect the optic bony canal wall between the end of the orbital funnel and the contralateral sphenoid cavity. The keys to successful operation were to appropriately adjust the angle between a microscope and patient's head, to early detect the anterior sphenoid wall and to open the funnel previous to the optic canal.

 All five patients treated with this method including a 7-year-old girl showed an immediate to early recovery after operation. Endonasal approach under a microscope proved to be safe and reliable as well as cosmetically favorable.
