description OBJECTIVE: To evaluate the usefulness of hemilaminectomy as a surgical approach in patients with intradural-extramedullary tumors. METHODS: Retrospective analysis of patients in which hemilaminectomy was as surgical approach in intradural-extramedullary tumors between June 2006 and December 2015. Demographics, preoperative symptoms, imaging characteristics, intraoperative findings, histological lineage, and postsurgical complications were analyzed. The average follow-up was 48.9 months (6–120 months). RESULTS: Fifty-three patients underwent hemilaminectomy. Tumor was located in the cervical level in 5 cases, in the dorsal level in 24, and in the lumbar region in 24 cases. Histological analysis revealed 28 neuromas, 11 meningiomas, 7 ependymomas, and 7 “multiple injuries.” Total resection without postsurgical neurologic deficit was possible in 96% of the patients. There were no recurrences on follow-up. CONCLUSION: Hemilaminectomy is an effective approach for the resection of lateralized cervicodorsal intradural-extramedullary tumors. It can also be used to treat midline lesions located in the lumbar level.
