Bilateral Open-Door Laminoplasty

Cervical laminoplasty has been widely used as an effective surgical treatment for cervical myelopathy caused by cervical spinal stenosis, ossification of the posterior longitudinal ligament (OPLL), and other conditions. Various techniques of cervical laminoplasty are available, and each has its advantages. In 1968, Kirita developed the procedure of extensive simultaneous multisegment laminectomy [1, 2] using a surgical air drill, with the aim of achieving atraumatic decompression of the spinal cord, while Hattori developed Z-shaped laminoplasty [3]in which the lamina was preserved to ensure cervical support and prevent nerve compression by postoperative scarring. Recognizing the varying advantages of these techniques and making good use of their characteristics, we developed bilateral open-door laminoplasty [4-6] as a simpler operative technique in 1977.
