Predictive factors of long-term dorsal column dysfunction after intramedullary spinal cord tumor resection: a comparative case series

The DC dissection and preservation myelotomy technique is associated with lower long-term DCD and intraoperative SSEP loss and better health-related quality of life and disability when compared with the midline coagulation and incision technique. The myelotomy technique and intraoperative SSEP disappearance, even if transient, are major determinants of long-term disability and DCDs.
