Can you give me some info on minimally invasive resection of intradural extradullary spinal neoplasms?

Safe. These types of surgery are done in highly specialized centers by dedicated and committed pioneers. Steady hands, robotic technology and high magnification have made such operations possible and safe. Recovery is fast. One 17 month infant had similar nepolasm. It was resected completely in less than 3 hours. He was alert and feeling good 2 hours after the operation.
