Their close relationship with the optic nerve and ophthalmic artery makes surgical intervention highly complex. This video presents two illustrative cases\u2014an optic nerve sheath meningioma and an optic canal meningioma\u2014both treated using an endoscopic endonasal approach (EEA). This direct ventral corridor provides early optic canal decompression and panoramic visualization of critical neurovascular structures, avoiding optic nerve manipulation. The same technique was employed in both cases, but was tailored to the distinct surgical challenges of optic nerve sheath and optic canal meningiomas.<\/jats:p>\n                  <jats:p>\n                    The video can be found here:\n                    <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" ext-link-type=\"uri\" xlink:href=\"https:\/\/stream.cadmore.media\/r10.3171\/2025.10.FOCVID25196\">https:\/\/stream.cadmore.media\/r10.3171\/2025.10.FOCVID25196<\/jats:ext-link>\n                  <\/jats:p>","DOI":"10.3171\/2025.10.focvid25196","type":"journal-article","created":{"date-parts":[[2026,1,1]],"date-time":"2026-01-01T05:52:11Z","timestamp":1767246731000},"page":"V12","source":"Crossref","is-referenced-by-count":0,"title":["Endoscopic endonasal surgery for optic nerve sheath and optic canal meningiomas: 2D operative video"],"prefix":"10.3171","volume":"14","author":[{"given":"Erik","family":"Burgos-Sosa","sequence":"first","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuanzhi","family":"Xu","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jonathan","family":"Lamano","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vera","family":"Vigo","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matei A.","family":"Banu","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Chang","sequence":"additional","affiliation":[{"name":"Otolaryngology, Head & Neck Surgery, Stanford University Hospital, Stanford, California"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Collin","family":"Liu","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan C.","family":"Fernandez-Miranda","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"issue":"Suppl 3","key":"b1","series-title":"Neurosurgery","first-page":"431","article-title":"Endoscopic endonasal approach to the optic canal: anatomic considerations and surgical relevance","volume":"11","author":"Abhinav K","year":"2015","unstructured":"Abhinav K, Acosta Y, Wang WH,  Endoscopic endonasal approach to the optic canal: anatomic considerations and surgical relevance.
