A variety of approaches have been described, and selection of approach should be tailored to the location of the tumor relative to neurovascular structures and surgical experience. The authors present two patients with petroclival meningiomas with varying relationships to cranial nerves and skull base anatomy who underwent endoscopic endonasal and open petrosectomy approaches, to demonstrate the complementarity of the endonasal transpetrous and open transpetrosal corridors. Proficiency in both open and endonasal approaches is critical to appropriate approach selection and maximal safe resection.<\/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\/2022.1.FOCVID21252\">https:\/\/stream.cadmore.media\/r10.3171\/2022.1.FOCVID21252<\/jats:ext-link>\n                  <\/jats:p>","DOI":"10.3171\/2022.1.focvid21252","type":"journal-article","created":{"date-parts":[[2022,4,1]],"date-time":"2022-04-01T07:06:17Z","timestamp":1648796777000},"page":"V9","source":"Crossref","is-referenced-by-count":1,"title":["Approach selection for resection of petroclival meningioma"],"prefix":"10.3171","volume":"6","author":[{"given":"Christina","family":"Jackson","sequence":"first","affiliation":[{"name":"Departments of Neurological Surgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kent S.","family":"Tadokoro","sequence":"additional","affiliation":[{"name":"Otolaryngology, University of Pittsburgh Medical Center, Pittsburgh, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eric W.","family":"Wang","sequence":"additional","affiliation":[{"name":"Otolaryngology, University of Pittsburgh Medical Center, Pittsburgh, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Georgios A.","family":"Zenonos","sequence":"additional","affiliation":[{"name":"Departments of Neurological Surgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carl H.","family":"Snyderman","sequence":"additional","affiliation":[{"name":"Otolaryngology, University of Pittsburgh Medical Center, Pittsburgh, Pennsylvania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul A.","family":"Gardner","sequence":"additional","affiliation":[{"name":"Departments of Neurological Surgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"issue":"1","key":"r1","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"211","DOI":"10.3171\/2017.4.JNS162483","article-title":"Contralateral transmaxillary corridor: an augmented endoscopic approach to the petrous apex","volume":"129","author":"Patel CR","year":"2018","unstructured":"Patel CR, Wang EW, Fernandez-Miranda JC, Gardner PA, Snyderman CH.
