| Summary: | <p><strong>Objective</strong> To evaluate the advantages and disadvantages of unilateral hemilaminectomy for the microsurgical removal of intraspinal tumors. <strong>Methods</strong> Clinical data of 19 patients with intraspinal tumors were analyzed from August 2008 to April 2013. All cases were treated microsurgically using unilateral hemilaminectomy procedures. <strong>Results</strong> Tumors were totally removed in all patients, including 12 cases of schwannoma, 1 case of neurofibroma, 5 cases of spinal meningioma and 1 case of hemangioblastoma. After operation signs and symptoms of every patient were significantly improved. Postoperative follow-up period was 6-60 months. No recurrence and spinal instability were found. The average area of intraoperative unilateral hemilaminectomy was (15 ± 2) mm × (32 ± 5) mm. <strong>Conclusion</strong> Unilateral hemilaminectomy for the removal of intraspinal tumors is a mini-invasive procedure, and is beneficial to the stability of spine, with the advantages of short hospitalization time, slight postoperative reaction and good long-term outcome. However, the procedure requires a skilled technology. <br /><br />doi: 10.3969/j.issn.1672⁃6731.2013.11.007</p><p>Video: <a title="Resection of hemangiolastoma located in the dorsal of spinal cord" href="/index.php/cjcnn/pages/view/v13n11a7" target="_blank">http://www.cjcnn.org/index.php/cjcnn/pages/view/v13n11a7</a></p>
