Abstract

Single staged posterior approach was carried out for three patients of dumbbell shaped schwannomas at the cervical region. Gross total resection was achieved in all of the patients, using a modified posterior midline exposure with hemilaminectomy and complete unilateral facetectorny. This exposure provided contiguous intraspinal, foraminal and extraforaminal access delete up to 2-3cm from lateral dural margin. The vertebral artery could be safely preserved from tumor mass. Although the follow up period is short, three patients showed no postoperative cervical spinalies from these operation. Illustrations of this approach with its possible application is discussed.
