Abstract: The C1–2 level is a relatively common location for extradural neurogenic tumors. However, surgical access to this region is anatomically demanding because of its close relationship to the vertebral artery and the spinal cord. To our knowledge, there have been no previous reports of using the unilateral biportal endoscopic (UBE) technique for such cases. We present the first successful removal of a C1–2 extradural tumor using UBE, demonstrating the feasibility, safety, and effectiveness of this approach.
