Minimally invasive microsurgical treatment of cervical intraspinal extramedullary tumors

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 a classical laminectomy was 3+/-0.39 hours and blood loss was 123+/-34 mL. Twenty-five patients had their tumors removed entirely, and two patients had partial removal. Twenty-six patients were followed-up for between 38 months and 7 years (mean=5 years), of whom 23 improved and three remained in a stable condition. One patient with a meningioma had a tumor recurrence 3 years post-operatively and underwent further surgery. The surgical time for the hemilaminectomy or hemi-semi-laminectomy group was 2.5+/-0.3 hours and blood loss was 88+/-18 mL. All patients were followed-up for between 26 and 42 months (mean=31 months) and 11 recovered to an improved grade while one remained in a stable condition. No patient had a tumor recurrence. The hemilaminectomy or hemi-semi-laminectomy approach achieved similar clinical outcomes to the conventional posterior midline laminectomy approach and was also associated with a shorter operative time, decreased intraoperative blood loss, greater preserved ligament and bone structure and a reduced deformity rate
