Abstract:
Objective To investigate the therapeutic effect of the hemilaminectomy approach in intraspinal tumor with the help of intraoperative ultrasound,high-speed drill and ultrasound knife.Methods Clinical data of 35 cases with the intraspinal tumor were analyzed retrospectively.All the patients were treated by hemilaminectomy approach,the position of the lesions were fixed by preoperative X-ray and intraoperative ultrasound,root of the spinous process were removed in order to achieve adequate visual field by high-speed drill and ultrasound knife.Electrophysiologic monitoring were used if the lesions were in the spinal cord.Results Total surgical resection was achieved in 32 cases,gross total resection was in 3 cases.Twenty-eight of the 35 cases were followed up.The symptom alteration of the first period ( 1 - 3 months postoperative):improved in 25 cases,no changed in 2 cases,aggravated in 1 case.The symptom alteration of the second period (6-24 months postoperative):no changed in all cases,no stability change of the vertebral column had been found.Conclusions Followed with the development of the electrophysiologic monitoring,high-speed drill,intraoperative ultrasound,the indication of the hemilaminectomy and have no influence of the spinal stability.However,to spinal meningioma which have a wide base,the hemilaminectomy approach may not adapt.
