Thirty-five percent of chordomas occur in the spheno-occipital region. We present a case of a clival chordoma that had severe brainstem compression. The patient had a 1-year history of slurred speech and left facial weakness (House-Brackmann 3). The endoscopic endonasal transclival approach gave a panoramic view of the region without the necessity of brain retraction or manipulation of the surrounding cranial nerves. Gross-total resection was achieved and no CSF leak was encountered postoperatively. The left facial weakness improved to House-Brackmann 1.<\/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:\/\/youtu.be\/DzW9Q6ckTHw\">https:\/\/youtu.be\/DzW9Q6ckTHw<\/jats:ext-link>\n                    .\n                  <\/jats:p>","DOI":"10.3171\/2020.4.focusvid.19942","type":"journal-article","created":{"date-parts":[[2020,4,25]],"date-time":"2020-04-25T22:01:18Z","timestamp":1587852078000},"page":"V12","source":"Crossref","is-referenced-by-count":1,"title":["Endoscopic endonasal resection of a clival chordoma with massive brainstem compression"],"prefix":"10.3171","volume":"2","author":[{"given":"Mostafa","family":"Shahein","sequence":"first","affiliation":[{"name":"Departments of Neurological Surgery and"},{"name":"Department of Neurosurgery, Aswan University Hospitals, Aswan University, Aswan, Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thiago","family":"Albonette-Felicio","sequence":"additional","affiliation":[{"name":"Departments of Neurological Surgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giuliano","family":"Silveira-Bertazzo","sequence":"additional","affiliation":[{"name":"Departments of Neurological Surgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rafael","family":"Martinez-Perez","sequence":"additional","affiliation":[{"name":"Departments of Neurological Surgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcus","family":"Zachariah","sequence":"additional","affiliation":[{"name":"Departments of Neurological Surgery and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ricardo L.","family":"Carrau","sequence":"additional","affiliation":[{"name":"Departments of Neurological Surgery and"},{"name":"Otolaryngology\u2013Head and Neck Surgery, The Ohio State University Wexner Medical Center, Columbus, Ohio; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel M.","family":"Prevedello","sequence":"additional","affiliation":[{"name":"Departments of Neurological Surgery and"},{"name":"Otolaryngology\u2013Head and Neck Surgery, The Ohio State University Wexner Medical Center, Columbus, Ohio; and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Laryngoscope","doi-asserted-by":"publisher","first-page":"1550","DOI":"10.1002\/lary.20975","article-title":"Reverse rotation flap for reconstruction of donor site after vascular pedicled nasoseptal flap in skull base surgery","volume":"120","author":"Caicedo-Granados E","year":"2010","unstructured":"Caicedo-Granados E, Carrau R, Snyderman CH, Prevedello D, Fernandez-Miranda J, Gardner P, : Reverse rotation flap for reconstruction of donor site after vascular pedicled nasoseptal flap in skull base surgery.
