Abstract：Objective To explore the feasibility and effectiveness of microsurgical treatment of intraspinal tumor by hemilaminectomy approach. Methods The clinical data of 106 patients with intraspinal tumors were analyzed retrospectively. Microsurgery via hemilaminectomy approach was performed in all the patients. The bone window for hemilaminectomy was 10-15 cm in size and differed from 1 segment to 9 segments. The neurophysiological monitoring was performed in 20 patients. Results Total resection was achieved in 98 patients, near-total in 5, sub-total in 3. All the symptoms were improved but one with intramedullary tumor whose neurological function deteriorated after operation. There was no spinal deformity by X-ray, CT or MRI reexaminations. Recurrence was found in 1 patient with spinal meningiomas during follow-up of 3 to 34 months. Conclusions Hemilaminectomy approach can be applied to resect quite a lot of intraspinal tumors because of its minor effect on the stability of spine with minimal invasion and quick recovery. Meanwhile, the application of a high-speed drill, intraoperative electrophysiological monitoring and intraoperative ultrasound can improve the protection of spinal neurological function and decrease the risk of operation and complications after operation.
