脑外伤患者中有6-8％伴有视神经管骨折。骨折片压迫视神经可引起视神经缺血、水肿和变性,最终导致永久性视力障碍甚至失明。唯一的有效治疗方法是尽早手术取除骨折碎片,全程开放视神经骨管以松解视神经的受压状态。作者采用鼻外经筛蝶窦进路视神经管减压术治疗了11例外伤性视神经管骨折导致失明的病人,有效率为72％。其中效果最好的一例在术后视力恢复到0.9,另外0.4,0.2各一例,0.1二例,0.05、0.01各一例,指动一例,其余三例无效。从上述病例的临床治疗中,可以看到:1、脑外伤后发生失明的时间越短,治
6-8% of traumatic brain injury with optic canal fracture. Fractures of the optic nerve compression can cause optic nerve ischemia, edema and degeneration, eventually leading to permanent vision disorders or even blindness. The only effective treatment is to remove the fracture as soon as possible surgery, the entire open optic canal to loosen the optic nerve compression state. The authors adopted the nasal canal by the sphenoid sinus approach optic canal decompression in the treatment of 11 cases of traumatic optic nerve canal fracture leading to blind patients, the effective rate was 72%. One of the best results in the postoperative visual acuity recovered to 0.9, the other 0.4,0.2 each one case, 0.1 two cases, 0.05,0.01 each one case, refers to the move in one case, the remaining three cases are invalid. From the clinical treatment of the above cases, we can see: 1, the shorter the time of blindness occurred after traumatic brain injury, governance
