The combined petrosal approach allows a wide exposure of the petroclival region and provides multiple angles of attack, limiting brain retraction.<\/jats:p>\n                  <jats:p>The authors present the case of a 54-year-old man with a large left petroclival meningioma responsible for headaches, dysphagia, and trigeminal neuralgia. The lesion was resected using a combined petrosal approach. A progressive improvement of the preoperative symptoms was observed. Postoperative MRI showed a near-total resection of the tumor, along with reexpansion of the brainstem.<\/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.FOCVID21226\">https:\/\/stream.cadmore.media\/r10.3171\/2022.1.FOCVID21226<\/jats:ext-link>\n                  <\/jats:p>","DOI":"10.3171\/2022.1.focvid21226","type":"journal-article","created":{"date-parts":[[2022,4,1]],"date-time":"2022-04-01T07:06:17Z","timestamp":1648796777000},"page":"V6","source":"Crossref","is-referenced-by-count":4,"title":["Combined petrosal approach for resection of a large left petroclival meningioma"],"prefix":"10.3171","volume":"6","author":[{"given":"Francesco","family":"Paglia","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Lariboisiere Hospital, Paris Diderot University, Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lorenzo","family":"Giammattei","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Lariboisiere Hospital, Paris Diderot University, Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paolo","family":"di Russo","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Lariboisiere Hospital, Paris Diderot University, Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sebastien","family":"Froelich","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Lariboisiere Hospital, Paris Diderot University, Paris, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"issue":"11","key":"r1","series-title":"Acta Neurochir (Wien)","doi-asserted-by":"publisher","first-page":"2343","DOI":"10.1007\/s00701-019-04022-z","article-title":"How I do it: combined petrosectomy","volume":"161","author":"Hanakita S","year":"2019","unstructured":"Hanakita S, Watanabe K, Champagne PO, Froelich S.
