Unilateral Bi-portal Endoscopic Decompression via the Contralateral Approach in Asymmetric Spinal Stenosis: A Technical Note

We discuss the technical details and operative advantages of approaching pathologies from the contralateral side in cases of asymmetric spinal stenosis. The contralateral approach offers better manipulative freedom and a more accessible target approach along the plane of the pathology, allowing safer decompression and facet preservation; further, this approach is ergonomic for surgeons. We recommend the adoption of this approach in decompressing asymmetric spinal stenosis.
