Cervical laminoplasty (Hattori's method) has been applied to patients with cervical myelopathy since 1971. A 53-year-old man, operated upon with this method 11 years ago, visited our clinic with paraplegia on July, 1995.Laminectomy were done and the enlarged laminae were examined for X-ray and histological evaluation. Z-sharped laminae achieved hard union, and new bone formation was mainly seen at dorsal side of the laminae. Histologically, thin scar tissue was formed slightly on the durai side. It can be confirmed flom this case that cervical laminoplasty fulfilled the function of the spinal canal with structural bone covering the spinal cord, and obtained moderate limitation of range of motion, with less scar formation around the dura mater.
