[Optic nerve decompression by the transorbital sphenoethmoidal approach].

5 cases of intracanalicular optic nerve injury were treated with decompression by the transorbital-sphenoethmoidal approach. The methodology and a typical case were presented. The indications and principles of the operation were discussed. The authors deemed the procedure facile, safe and with few complications, hence worthy of recommendation for early adoption, preferably within 2 weeks after the trauma for good effect.
