Clinical Value Of The Unilateral Hemilaminectomy Approach In The Treatment Of Subdural Extramedullary Tumors

Objective To compare the clinical results of the unilateral hemilaminectomy appr oach and the total laminectomy approach in the treatment of subdural extramedullary t umorsMethod 100 cases with subdural extramedullary tumors in September 2012- Sep tember 2014 in the General Hospital of Ningxia Med. Univ. underwent surgery interve ntion were prospective analyzed.Among them,50 cases(the observation group) received tumor resection by the unilateral hemilaminectomy approach,another 50 cases(the contr ol group) received the treatment by the total laminectomy approach.All received electro physiological monitoring in the operation.Operation time,intraoperative bleeding,postoper ative hospitalization duration and postoperative recurrence rate in 6 months to 1 year e tc. were recorded and compared.Results Operation time,intraoperative bleeding,postoperative hospitalization duratio,costs and postoperative fields time in the the observation group were less than the con trol group(P <0. 05).There was no significant difference in curative effect aspects.In th e postoperative follow-up(6 months to 1 year),the spinal instability cases in the observat ion group(0 case) was significantly less than the control group(6 cases).Conclusion Compared with the total laminectomy approach,the unilateral hemilam inectomy approach in the treatment of subdural extramedullary tumors has more advant ages as follows:better curative effect, smaller trauma, quicker recovery, fewer complicat ions, great maintenance in spinal mobility and stability etc.
