Despite favorable outcomes reported in the literature, predictors of functional recovery remain clinically relevant, particularly in resource-limited settings.<\/jats:p>\n <\/jats:sec>\n \n Methods:<\/jats:title>\n We retrospectively reviewed 170 consecutive patients who underwent microsurgical excision of spinal IDEM tumors at a single tertiary care center over a 10-year period. Preoperative neurological status was assessed using Frankel grading, and pain was evaluated using the Denis pain scale (DPS). All tumors were approached through a posterior, facet-sparing technique. Functional outcomes were assessed postoperatively, at 2 weeks, and at 6 months. Factors influencing outcomes were analyzed using univariate statistical methods.<\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n Gross total resection was achieved in 93% of patients. At final follow-up, 157 patients (92.4%) demonstrated a good functional outcome, including 84 (49.4%) patients with \u22652-grade improvement in Frankel score. Poor preoperative neurological status (Frankel A\u2013C) and ventral axial tumor location were significantly associated with poorer outcomes (\n P<\/jats:italic>\n = 0.010 and\n P<\/jats:italic>\n = 0.026, respectively). Mean DPS scores improved significantly following surgery (\n P<\/jats:italic>\n < 0.001). Postoperative complications were infrequent, and there was no operative mortality.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n Microsurgical excision of IDEM tumors through a posterior, facet-sparing approach provides favorable neurological and pain outcomes with low morbidity. Preoperative neurological status and ventral tumor location are important predictors of postoperative recovery. Early surgical intervention remains critical for optimizing functional outcomes.<\/jats:p>\n <\/jats:sec>","DOI":"10.25259\/sni_123_2026","type":"journal-article","created":{"date-parts":[[2026,4,3]],"date-time":"2026-04-03T08:17:22Z","timestamp":1775204242000},"page":"200","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Functional outcomes after surgery for intradural extramedullary spinal tumors: A retrospective study"],"prefix":"10.25259","volume":"17","author":[{"given":"Vartika","family":"Gupta","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pankaj","family":"Gupta","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10894","published-online":{"date-parts":[[2026,4,3]]},"reference":[{"key":"10.25259\/SNI_123_2026\/ref-1","doi-asserted-by":"crossref","first-page":"301","DOI":"10.1007\/s00234-007-0345-7","article-title":"Intradural spinal tumors: Current classification and MRI features","volume":"50","author":"Abul-Kasim","year":"2008","journal-title":"Neuroradiology"},{"key":"10.25259\/SNI_123_2026\/ref-2","doi-asserted-by":"crossref","first-page":"277","DOI":"10.4184\/jkss.2003.10.3.277","article-title":"A 6-year observation of multiple spinal schwannomas before excision: A case report","volume":"10","author":"Ahn","year":"2003","journal-title":"J Korean Soc Spine Surg"},{"key":"10.25259\/SNI_123_2026\/ref-3","doi-asserted-by":"crossref","first-page":"165","DOI":"10.4055\/cios.2009.1.3.165","article-title":"The surgical treatment for spinal intradural extramedullary tumors","volume":"1","author":"Ahn","year":"2009","journal-title":"Clin Orthop Surg"},{"key":"10.25259\/SNI_123_2026\/ref-4","doi-asserted-by":"crossref","first-page":"291","DOI":"10.4103\/1793-5482.162707","article-title":"Spinal tumors: Trends from Northern India","volume":"10","author":"Arora","year":"2015","journal-title":"Asian J Neurosurg"},{"key":"10.25259\/SNI_123_2026\/ref-5","doi-asserted-by":"crossref","first-page":"85","DOI":"10.1038\/sj.sc.3101394","article-title":"Clinical features associated with recurrence of tumours of the spinal cord and cauda equina","volume":"41","author":"Asazuma","year":"2003","journal-title":"Spinal Cord"},{"key":"10.25259\/SNI_123_2026\/ref-6","doi-asserted-by":"crossref","first-page":"1063","DOI":"10.3349\/ymj.2014.55.4.1063","article-title":"Combined muscle motor and somatosensory evoked potentials for intramedullary spinal cord tumour surgery","volume":"55","author":"Choi","year":"2014","journal-title":"Yonsei Med J"},{"key":"10.25259\/SNI_123_2026\/ref-7","doi-asserted-by":"crossref","first-page":"1103","DOI":"10.3390\/jpm13071103","article-title":"Is there a role for intraoperative neuromonitoring in intradural extramedullary spine tumors? results and indications from an institutional series","volume":"13","author":"D\u2019Ercole","year":"2023","journal-title":"J Pers Med"},{"key":"10.25259\/SNI_123_2026\/ref-8","doi-asserted-by":"crossref","first-page":"248","DOI":"10.1016\/j.clinph.2007.09.135","article-title":"Intraoperative neurophysiological monitoring of the spinal cord during spinal cord and spine surgery: A review focus on the corticospinal tracts","volume":"119","author":"Deletis","year":"2008","journal-title":"Clin Neurophysiol"},{"key":"10.25259\/SNI_123_2026\/ref-9","doi-asserted-by":"crossref","first-page":"142","DOI":"10.1097\/00003086-198410000-00015","article-title":"Acute thoracolumbar burst fractures in the absence of neurologic deficit.
