TRANSCRANIAL OPTIC NERVE DECOMPRESSION FOR FRONTO-ORBITO-SPHENOIDAL FIBROUS DYSPLASIA / 解放军医学杂志

ABSTRACT

To evaluate clinical effect of transcranial optic nerve decompression on fronto orbito sphenoidal fibrous dysplasia with progressive vision loss, 25 cases were studied retrospectively. All patients had undergone transcranial optic nerve decompression. One week after operation, 21 patients experienced improvement or stability in vision, but 4 patients complained reduction in vision. Before operation, the vision of the affected eye was near blindness in 3 cases among the 4 cases who failed to gain improvement in vision after operation. Effective follow up was achieved in 18 cases, and the follow up period was from two to twenty two years (average six years). Among them, only 3 paticnts showed recurrence of visual disturbance. The results showed that transcranial optic nerve decompression was effective in rescuing vision in fronto orbito sphenoidal fibrous dysplasia with progressive vision loss. Once the patient was near blind before the operation, the surgical result was unsatisfactory.
