title: [Research of optic canal decompression by transnasal endoscopic approach].
abstract: OBJECTIVE
  To find a better method to treat traumatic optic neuropathy.
  
  
  METHODS
  Fourteen cases were treated by transnasal endoscopic sphenoethmoidal optic canal decompression in clinic.
  
  
  RESULTS
  Nine of them had their visual acuity improved from NLP, HM, FC/50 cm, HM, NLP, LP, NLP, HM, NLP to 0.2, 0.3, 0.3(+2), 0.4, 0.06, 0.3, 0.1, 0.7, 0.12 after the operation. The clinical anatomy, attentions during operation, merits of operative approaches were discussed.
  
  
  CONCLUSIONS
  Transnasal endoscopic sphenoethmoidal optic canal decompression is a good method for treatment of post-traumatic optic neuropathy.
