One-piece resection for the treatment of ventral intradural extramedullary spinal meningioma: a retrospective study

One-piece resection was a feasible, safe and effective procedure for treating VIESMs. Partial removal of the ipsilateral pedicle, facet joint, and even posterior vertebral wall to establish a wide surgical corridor and vision, resection of the dentate ligaments to minimize spinal cord traction, and meticulous coagulation of the dural attachment to reduce recurrence were the key technical points.
