Surgical Treatment of Dumbbell Type Tumor of Cervical Spine.

The authors operated on 61 tumors of the cervical spinal cord from 1980 to 2000, of which 15 were dumbbell tumors. Two were resected by anterior approach, 8 by posterior approach, and 7 by both the anterior and posterior approaches simultaneously. To preserve the alignment of neck, laminoplasty or partial laminectomy with bone graft was performed. The tumors were resected including the capsule to prevent recurrence, and gross total resection was achieved in 13 patients. There were no symptoms of recurrence.
