Traditional surgery for spinal tumors involves midline incision, extensive dissection, muscle damage, blood loss, ligament injury, and bone removal, with an elevated risk of complications. In contrast, minimally invasive techniques cause less soft tissue trauma, bleeding, infections, cerebrospinal fluid leaks, while enabling shorter hospital stays, and yielding similar results compared to open surgery. There have been reports of prior studies have reported the full endoscopic excision of small intradural extramedullary tumors. Here we report a case of a large intradural extramedullary tumor treated with a full endoscopic translaminar approach and dural repair.

Endoscopy is becoming popular in the treatment of various spinal conditions. Soft tissue clearance is a challenge in interlaminar endoscopic spine surgery. The first author (KM) has been using monopolar electrosurgery for the last 7 years. Monopolar electrosurgery is efficient, quick, and cost-effective. However, a thorough knowledge of monopolar electrosurgery is required to avoid complications.
