[Anterior approach for cervical dumb-bell typed neurinomas].

We experienced three cases of the dumb-bell typed cervical neurinoma. All of them compressed the spinal cord in the spinal canal, and had developed through the intervertebral foramen and compressed and displaced the vertebral artery. The decompression of the vertebral artery and reconstruction of the spine as well as the removal of the tumor were thought to be important. We used the anterior approach and were able to operate safely and completely. The anterior approach was thought to be effective for the surgical treatment of dumb-bell typed cervical neurinoma.
