RESUMO
Objective To study the feasibility of semi-laminectomy procedures for the management of intradural extramedullary tumors of the spinal cord.Method Retrospective analysis of 19 cases of in-tradural extramedullary tumors of the spinal cord were treated by the approach of semi-laminectomy.including 11 cases of neurilemmoma and 8 cases of meningioma.Results Seventeen cases of extraspinal tumors were totally resection,2 of dumbbell neurilemmomas underwent subtotal resection.No new neurologi-cal disfunetions as well as recurrence or comphcations were found in all cases after the operation.Conclu-sion Semi-laminectomy procedures for the management of intradural extramedullary tumors of the spinal cord is a mini-invasive procedure,and is beneficial to the stability of spine,with the advantages of short hos-pitalization time,slight postoperative reactions and less complications.
