摘要
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.
