Abstract：Objection To investigate the feasibility and effectiveness of the fenestration microsurgery for intraspinal tumor by a small incision and hemilaminectomy.Methods Fenestration operation by small incision and hemilaminectomy were performed in 21 patients with intraspinal tumors via posterior midline approach.The extent of tumor resection was reviewed by MRI 5 to 7 days after the operation,and three dimensional CT was performed to confirm the degree of bone destruction in the spine.Results Total tumor resection was achieved in 21 patients during the operation,there was no residual tumor found by MRI examination,and no injury to the spinous and articular process and damage of spinal stability by 3D spinal canal CT after the operation.Pathological examination showed meningioma in 2 patients and neurilemmoma in 19.Postoperative incision cerebrospinal fluid leakage occurred in 1 patient,and recovery after strengthening skin suture.During a follow-up period of 1 to 13 months,neither patient recurred,nor infection or rupture of incision occurred.Conclusions Total tumor resection can be achieved in most of the spinal subdural tumors through fenestration operation with small incision and hemilaminectomy,which can lessen the damage to the muscle,fascia and bone,can maintain the spinal stability,meet the requirements of the patients for beauty and reduce postoperative complications.
