Abstract

Objective: To evaluate the surgical results of optic nerve sheath meningiomas. Subject and method: A prospective and descriptive study, 12 patients optic nerve sheath meningiomas who underwent surgery at the Neurosurgery department of ChoRay Hospital from 01/01/2017 to 30/09/2019. We descriptived clinical and MRI features of all patients. The post-operative results were evaluated by neuroophthalmological improvability, total tumoral resection and complications at the 3 month post-op. Result: Mean age of the 5 male (41.7%) and 7 female (58.3%) patient was 40.6 ± 14.7 years (ranging 13 - 61 years). The most common presenting symptoms were exophthalmos and decreased visual acuity (100%), optic disc atrophy (50%), and pain (16.7%). In 3 (25%) cases, the tumors invasive intracranial. The mean diameter of orbital tumors was 33.6 ± 9.6mm (18 - 45mm). The diagnosis was based on pathology and the tumors were all grade I meningiomas. Transcranial orbitotomy approach was used in all cases. Total resection was achieved in 7 patients (58.3%) while subtotal resection was 41.7%. No one died in this study. There was not intraorbital or intracranial hematoma or infection. The mean follow up period was 24.5 months (range from 9 months to 39 months), ten patients (83.3%) experienced loss of vision. Conclusion: Surgical treatment is often associated with loss of vision in the affected eye. Surgical intervention is recommended in patients with no useful vision, significant proptosis and for preventing contralateral eye spread.
