Objective To evaluate the effectiveness of transfrontal craniotomy decompression of optic nerve on traumatic blindness.Methods 31 patients with total blindness were treated by transfrontal craniotomy decompression of optic nerve,which allowed complete decompression of the optic canal,incision of optic sheath,and removal of apical orbital bone fragments.Results After operation,16 cases recovered visual acuity.The cure rate of this treatment was 51.5%.Conclusion Transfrontal craniotomy for decompression of optic nerve is the only way to completely decompress the optic nerve.
