Conventional posterior approach for resection of an intradural tumor at C2 involves C2 lamincectomy and detachment of extensor muscles from C2 spinous process. Being major extensors of the cervical spine, the destruction of C2-attached muscles may lead to detrimental consequences, namely, neck pain, limited neck motion, progressive kyphosis, and instability. We report a new technique on exposing and reconstructing the C2 level while preserving C2 extensors for resection of an intradural tumor at C2 level. We performed an en bloc hemilaminectomy of C2 while carefully preserving C2 extensor muscles to adequately expose the dura mater at the C2 level. After removal of the tumor, we proceeded with the reconstruction by recapping the C2 hemilamina using 2 laminar screws.
