Removal of intraspinal tumors by the classic posterior midline approach with laminectomy may cause damage to and instability of cervical segments. We investigated whether the less invasive hemilaminectomy or hemi-semi-laminectomy can achieve satisfactory clinical outcomes in 39 patients with intraspinal extramedullary tumors of the cervical spine. Twenty-seven patients were treated with conventional microsurgery using a posterior midline approach; and were compared to 12 patients treated with hemilaminectomy or hemi-semi-laminectomy using a posterior midline approach. Patients were retrospectively reviewed and their preoperative and postoperative clinical status was measured using the Frankel Grade. The surgical time for the 27 patients who underwent…
