To compare the etfectiveness of two kinds of operation which Combined fronto temporal orbito zygomatic intradural and epidural combined approach or Simple pterional approach of Decompression of optic canal

Objective Analysis and comparison of combined fronto temporal orbito zygomatic intradural and epidural combined approach and simple pterional approach for decompression of optic nerve canal curative effect.Methods A retrospective summary of 1998 January to 2011 September Tangshan City people's hospital using different approach for decompression of optic nerve canal in 58 cases operation effect.Results Approach of decompression of optic canal 28 cases total efficiency of 71.43%,combined fronto temporal orbito zygomatic epidural combined approach for decompression of optic nerve canal in 30 cases of the total efficiency of 80%.Conclusion The combined fronto temporal orbito zygomatic epidural combined approach to safe operation,good effect and less complication after operation.
