ABSTRACT

The surgical approach to spinal tumors varies not only with the level and location of the tumor, but also with the type and extent of the tumor. Some of the dumbbell neurofibroma(neurilemmoma) can be removed through simple laminectomy, but usually are approached through two separate incisions by two stages. In this report, posterior and anterolateral approaches in a single stage to dumbbell neurofibroma(neurilemmoma) of the spinal region are described. This approach provides full exposure of intra- and paraspinal portions of the tumor, thus permitting safe dissection and total removal. Six patients who underwent this procedure are described to illustrate its application.
