Abstract

Lumbar Intradural extramedullary schwannomas often cause neurological symptoms, and complete surgical removal is mandatory. Traditional surgical procedures for tumor removal have numerous disadvantages, including extensive muscle dissection, prolonged recovery, and increased postoperative pain. As endoscopic surgery becomes increasingly popular for treating spinal disorders, the use of endoscopic techniques for treating spinal tumors is imminent. However, the development of these techniques has been challenging due to various inherent difficulties with traditional endoscopic surgery, including a steep learning curve, technical complexity, and fluid management. In this article, we present a successful case of treating an intradural extramedullary schwannoma using unilateral biportal endoscopy (UBE), share the 2-hand technique involved, and discuss the advantages and limitations of UBE in such cases.
