Several approaches have been described to achieve gross-total resection with low morbidity and mortality. In this 2-dimensional operative video, the authors show a simultaneous combined transpetrosal approach. The patient is a 44-year-old woman with an 8-month history of gait imbalance with evidence of a giant petroclival meningioma on neuroimaging. She underwent a combined middle fossa approach with anterior petrosectomy and retrosigmoid\/retrolabyrinthine approach to achieve gross-total tumor resection. The postoperative course was characterized by trigeminal neuralgia, and neuroimaging showed gross-total resection of the tumor.<\/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.FOCVID21248\">https:\/\/stream.cadmore.media\/r10.3171\/2022.1.FOCVID21248<\/jats:ext-link>\n                  <\/jats:p>","DOI":"10.3171\/2022.1.focvid21248","type":"journal-article","created":{"date-parts":[[2022,4,1]],"date-time":"2022-04-01T07:06:17Z","timestamp":1648796777000},"page":"V8","source":"Crossref","is-referenced-by-count":1,"title":["Combined transpetrosal approach for giant petroclival meningioma: 2-dimensional operative video"],"prefix":"10.3171","volume":"6","author":[{"given":"Vera","family":"Vigo","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Stanford University School of Medicine, Stanford, California; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karam","family":"Asmaro","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Stanford University School of Medicine, Stanford, California; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maximiliano A.","family":"Nu\u00f1ez","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Stanford University School of Medicine, Stanford, California; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahmed","family":"Moyheldin","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Stanford University School of Medicine, Stanford, California; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert K.","family":"Jackler","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery, Stanford University School of Medicine, Stanford, California"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan C.","family":"Fernandez-Miranda","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Stanford University School of Medicine, Stanford, California; and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"issue":"1","key":"r1","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"40","DOI":"10.3171\/2013.8.JNS13535","article-title":"True petroclival meningiomas: results of surgical management","volume":"120","author":"Almefty R","year":"2014","unstructured":"Almefty R, Dunn IF, Pravdenkova S, Abolfotoh M, Al-Mefty O.
