ObjectiveTo review the application and progress of unilateral biportal endoscopy (UBE) technology in the treatment of cervical degenerative diseases, and to provide reference for clinical treatment decisions. MethodsThe literatures related to UBE in the treatment of cervical spondylotic radiculopathy (CSR) and cervical spondylotic myelopathy (CSM) at home and abroad were extensively reviewed, and the surgical methods, indications, effectiveness, and safety were analyzed and summarized. ResultsUBE technology is effective in the treatment of CSR and CSM, and has the advantages of good surgical field, reducing the injury of the posterior structure of the cervical spine, and protecting the facet joint process, but in general, the indications are relatively narrow, limited to single-segment or adjacent double-segment lesions, and the requirements for the operator are relatively high, and the learning curve is long. ConclusionUBE technology can be applied to the treatment of CSR and CSM, but it needs to be carried out by experienced UBE surgeons for specific cases.
