Surgical intervention achieving a gross total resection is the main treatment modality. If, however, a gross total resection cannot be achieved, surgery is augmented with radiation therapy. In this video, we present the case of a 27-yr-old male with persistent back pain and radiculopathy who was found to have a myxopapillary ependymoma that was adherent to the conus. Preoperative imaging demonstrated that the tumor was displacing the conus and nerve roots ventrally. A laminoplasty at L1-L2 was performed with near-total resection because of the intimate involvement of neural tissue. The key features of the video include performing laminoplasty and rationale, and performing maximum safe tumor resection with a combination of bipolar cautery, suction, and ultrasonic aspiration augmented with frequent stimulation, gel foam pledgets intradurally, and achieving a watertight closure of the dura and fascia. The patient tolerated the surgery well without any complications. Given his gross residual disease along the conus and young age, he was at a high risk for continued tumor growth without adjuvant therapy, with a recurrence rate of roughly 33% to 45% in patients who underwent subtotal resection. With the addition of adjuvant radiation therapy, the recurrence rate is 20% to 29%.\n                    <jats:sup>1,2<\/jats:sup>\n                    He was discharged to home with a plan for conventional fractionated external beam radiation. At the most recent follow-up, he reported decreased back pain and radiculopathy. Appropriate patient consent was obtained.\n                  <\/jats:p>","DOI":"10.1093\/ons\/opab038","type":"journal-article","created":{"date-parts":[[2021,3,1]],"date-time":"2021-03-01T19:12:58Z","timestamp":1614625978000},"page":"E352-E352","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":3,"title":["Lumbar Laminoplasty for Resection of Myxopapillary Ependymoma of the Conus Medullaris: 2-Dimensional Operative Video"],"prefix":"10.1227","volume":"20","author":[{"given":"Michael J","family":"Strong","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, University of Michigan, Ann Arbor, Michigan, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Timothy J","family":"Yee","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University of Michigan, Ann Arbor, Michigan, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Siri Sahib S","family":"Khalsa","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University of Michigan, Ann Arbor, Michigan, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yamaan S","family":"Saadeh","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University of Michigan, Ann Arbor, Michigan, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert","family":"North","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University of Michigan, Ann Arbor, Michigan, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mark E","family":"Oppenlander","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University of Michigan, Ann Arbor, Michigan, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2021,5]]},"reference":[{"issue":"2","key":"bib1-20251027","doi-asserted-by":"crossref","first-page":"E8","DOI":"10.3171\/2015.5.FOCUS15164","article-title":"Outcomes following myxopapillary ependymoma resection: the importance of capsule integrity","volume":"39","author":"Abdulaziz","year":"2015","journal-title":"Neurosurg Focus"},{"issue":"4","key":"bib2-20251027","doi-asserted-by":"crossref","first-page":"471","DOI":"10.3171\/2013.6.SPINE12927","article-title":"Tumor control after surgery for spinal myxopapillary ependymomas: distinct outcomes in adults versus children: a systematic review","volume":"19","author":"Feldman","year":"2013","journal-title":"J Neurosurg Spine"}],"container-title":["Operative Neurosurgery"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/academic.oup.com\/ons\/article-pdf\/20\/5\/E352\/37041543\/opab038.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/www.ovid.com\/10.1093\/ons\/opab038","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,7]],"date-time":"2026-08-07T16:59:33Z","timestamp":1786121973000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/10.1093\/ons\/opab038"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,2,27]]},"references-count":2,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2021]]}},"URL":"https:\/\/doi.org\/10.1093\/ons\/opab038","relation":{},"ISSN":["2332-4252","2332-4260"],"issn-type":[{"value":"2332-4252","type":"print"},{"value":"2332-4260","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,2,27]]},"assertion":[{"value":"2020-09-09","name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2020-12-28","name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}}]}}
