RESUMEN
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.
RESUMEN
To discuss the clinical situation and treatment of cervical intramedullary spinal teratoma, two cases of it in our department were presented, and the related literatures were reviewed. A concomitant anomaly of the cervical vertebral canal was found to be accompanied by cervical intramedullary spinal teratoma. MRI showed the tumors with mixed signal intensity. During operation the tumor was found to have both cysts and hard bony nodules. It was very difficult to remove the total tumor. It is concluded that the plain film of cervical vertebra and cervical spine MRI are sensitive to differentiate teratomas from other tumors. Surgery should be the first choice for treatment.
