An extranasal transethmoidal approach has been applied for optic canal decompression surgery in patients suffering from indirect traumatic optic neuropathy. However, this approach does not always offer a wide operative field to surgically manage the entire course of the optic canal, because the medial wall of the orbit bulges medially. In the last two years, we have performed optic canal decompression surgery in four patients who suffered from indirect traumatic optic neuropathy. Three of these patients underwent optic nerve decompression by an endonasal approach under endoscopic control and one patient by a transcranial approach. Two of the three patients who were operated on by the endoscopic endonasal approach showed a remarkable improvement in their visual acuity after surgery. The other lost his vision six days after surgery, because it was not possible to remove a relatively large bone fragment of the skull base which had compressed the optic nerve from above. One patient who underwent optic nerve decompression transcranially markedly recovered his vision. Compared to the external transethmoidal approach, endoscopic endonasal and transcranial approaches can provide a wide operative field for the decompression of the optic nerve. In addition, an endonasal approach under endoscopic control is less traumatic than an extranasal transethmoidal approach. A transcranial approach is also useful for the patients with severe skull base bone fracture.
