In these days, expansive laminoplasty is the most popular operation as posterior decompression surgery for patients of cervical spondylotic myelopathy.In 1974, expansive laminoplasty was started in our clinic. In this report, the authors described the postoperative results and radiographic observations on 43 cases (expansive laminoplasty in 25 cases and laminectomy in 18 cases) who were followed for more than 1 year. We compared expansive laminoplasty with laminectomy, in respect to postoperative results and radiographic observations, in order to examine whether it had more advantage.
