Abstract: Objective To analyze and compare the clinical effect of intraspinal tumor of thoracic spine between hemilaminectomy approach and complete laminectomy approach. Methods The clinical database was reviewed for patients with intraspinal tumor of thoracic spine who underwent surgical procedure by hemilaminectomy approach or total laminectomy between January 2010 and June 2016. Of 60 cases received surgery，32 underwent hemilaminectomy approach（observation group）and 28 complete laminectomy（control group）. The perioperative indicators，curative effect，the spinal stability and complications were compare between two groups. Results After surgery，the preoperative symptoms improved in all patients. Compared with complete laminectomy approach ，hemilaminectomy microsurgery showed better clinical effect. There were significant differences between the two groups in the operation time （t=8.473 ，P<0.001），the amount of intraoperative bleeding （t=17.612 ，P<0.001），the time of hospitalization（t=16.655，P<0.001），the time to go out of bed（t=54.138，P<0.001），spinal stability （χ2=6.184，P=0.013）. There was no statistically significant difference in the incidence of complications between two groups. Conclusion The clinical efficacy of hemilaminectomy approach for treatment of intraspinal tumor of thoracic spine is better than that of the laminectomy .
