Effect of routine extradural optic canal decompression performed by skull base trained surgeons on visual outcomes in patients with anterior skull base meningiomas

Patients with tuberculum sellae and anterior clinoid process meningiomas benefit from skull base surgeons trained in extradural optic canal decompression, as reflected by lower postoperative secondary visual acuity deterioration in patients treated by skull base trained surgeons. All cases presenting with tumors with optic apparatus involvement should be managed by skull base trained surgeons to maximize postoperative visual acuity preservation.
