title: [Microsurgical endonasal decompression of the optic nerve].
abstract: A new endonasal microsurgical technique for decompression after traumatic optic neuropathy is presented. Compared to the external transethmoidal, the transfrontal or the pterional approach, the main benefit of this method is the superb stereoscopic vision of the medial aspect of the optic canal. The nerve is approached from a 60 degree to 90 degree angle and continuous suction irrigation allows for safe removal of the bony shell. This surgery is done via the endonasal route and therefore has fewer serious complications compared to intracranial, extradural or intradural approaches. Additional trauma due to retraction of the brain is avoided. The anterior ethmoidal cells and the nasofrontal duct remain untouched, avoiding late mucocele formation.
