The far-lateral approach demonstrated here facilitates access to lesions involving the anterior portion of the foramen magnum.<\/jats:p><jats:p>In this video, we present a 62-year-old woman with hand numbness and weakness. The patient had significant difficulty in fine motor movements of both hands. In the neurological examination, she had a significant right-hand intrinsic muscle weakness and mild quadriparesis.<\/jats:p><jats:p>Magnetic resonance imaging (MRI) showed a dural-based homogeneously enhancing extra-axial mass in the anterior foramen magnum with a significant mass effect on the brain stem and the upper cervical cord. The decision was made to proceed with a far lateral transcondylar skull base approach including partial C1 laminectomy.<\/jats:p><jats:p>The surgery and postoperative course were uneventful. The postoperative MRI showed gross total resection of the mass. The histopathology indicated a WHO (World health Organization) grade-I meningioma. The patient's postoperative course was uneventful. She improved to normal neurological function within several weeks and continues to do well without recurrence at 20\u2009months' follow-up.<\/jats:p><jats:p>In this video, we demonstrated important steps for the microsurgical resection of these challenging lesions.<\/jats:p><jats:p>The link to the video can be found at: https:\/\/youtu.be\/_nuX2Y7YU9w.<\/jats:p>","DOI":"10.1055\/s-0039-1695063","type":"journal-article","created":{"date-parts":[[2019,10,15]],"date-time":"2019-10-15T18:59:16Z","timestamp":1571165956000},"page":"S360-S362","source":"Crossref","is-referenced-by-count":0,"special_numbering":"S","title":["Microsurgical Gross Total Resection of Foramen Magnum Meningioma via Far Lateral Approach"],"prefix":"10.1055","volume":"80","author":[{"given":"Sima","family":"Sayyahmelli","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, University of Wisconsin Medical School, Madison, Wisconsin, United States"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mustafa K.","family":"Ba\u015fkaya","sequence":"additional","affiliation":[{"name":"Department of Neurological Surgery, University of Wisconsin Medical School, Madison, Wisconsin, United States"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2019,10,15]]},"container-title":["Journal of Neurological Surgery Part B: Skull Base"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/s-0039-1695063.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,11,19]],"date-time":"2019-11-19T18:31:09Z","timestamp":1574188269000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/s-0039-1695063"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,10,15]]},"references-count":0,"journal-issue":{"issue":"S 04","published-online":{"date-parts":[[2019,11,19]]},"published-print":{"date-parts":[[2019,12]]}},"URL":"https:\/\/doi.org\/10.1055\/s-0039-1695063","relation":{},"ISSN":["2193-6331","2193-634X"],"issn-type":[{"value":"2193-6331","type":"print"},{"value":"2193-634X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,10,15]]}}}
