Meningiomas may grow into the optic canal even without evidence of involvement on MRI studies. We aim to investigate the effect of routine optic canal unroofing performed by skull base trained surgeons versus general neurosurgeons on the postoperative visual outcomes in anterior skull base meningiomas.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Between January 2013 and October 2023, consecutive patients in our institution who underwent craniotomies due to visual impairment were retrospectively reviewed. Patient records were screened for data on optic nerve compression, patient characteristics, lesion characteristics, intraoperative factors, the exact preoperative and postoperative visual acuity, as well as the postoperative clinical course. The primary outcome was the change in visual acuity postoperatively compared to the preoperative visual acuity. Multivariable linear regression analysis was performed with best postoperative visual acuity as a dependent adjusting for prognostic factors.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Out of 709 patients who underwent craniotomies for anterior skull base meningiomas, 94 patients showed optic nerve involvement on MRI. In total, 59 cases were treated by skull base trained surgeons and 35 by general neurosurgeons. Optic canal decompression was performed in 65% of the patients. There was no significant difference between patients treated by skull base surgeons and general neurosurgeons in terms of postoperative permanent complications. In patients with tuberculum sellae or anterior clinoid process meningiomas, postoperative secondary deterioration of visual acuity occurred in 40% (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u200910) of the cases treated by general neurosurgeons versus 11% (\n                      <jats:italic>n<\/jats:italic>\n                      \u2009=\u20094) in the group treated by skull base trained surgeons.
