Abstract: Compressive cervical myelopathy (CCM) is a common disease of spinal surgery. Various kinds of reasons such as herniation of cervical disc and ossification of the posterior longitudinal ligament (OPLL) lead to spinal canal stenosis, thereby compressing the spinal cord, and a series of neurological symptoms are caused. Currently, posterior cervical expansive open-door laminoplasty (PCEOLP) is widely used for cervical decompression in patients with CCM involving three or more levels. This operation can expand the spinal canal while preserving the posterior structures of the cervical spine, and non-neurological complications are relatively rare. However, there are characteristic complications to this procedure such as nerve root palsy, axial neck pain, and loss of range of motion (ROM). Various modified techniques of PCEOLP have been developed to reduce postoperative complications. In this review, clinical research progress of PCEOLP in recent years is summarized, mainly focusing on internal fixation of materials and methods, operative approach, cervical decompression level, combined application of different surgical procedures, opening size and application of new technologies.
