Abstract | OBJECTIVES: Some primary brainstem tumors, when extensive, are considered inoperable. We wanted to assess the value of robotic image-guided microscopic surgery in the resection of these tumors and to improve survival and quality of life for these patients. METHODS: Two patients with extensive brainstem tumors were evaluated at our center. They previously underwent several biopsies, attempted partial resections, radiotherapy and shunting. They presented with progressive neurological deterioration, ' coma vigil' for several months, and required life-supporting measures prior to surgery. Both patients underwent frameless stereotactic craniotomy using a MKM robotic microscope, intraoperative neurophysiological monitoring, and extensive resection of their recurrent brainstem tumors. RESULTS: In the immediate weeks after surgery, both patients became interactive and regained major motor and cranial nerve deficits present prior to surgery. Nine months after surgery, 1 patient succumbed to pneumonia. At 2 years after the operation, 1 patient has maintained his neurological status and showed no recurrence on imaging studies. CONCLUSIONS:
Image-guided surgery with an MKM microscope allows surgical outlines to be injected in the microscope viewer and facilitates resection of extensive brainstem tumors previously considered inoperable.
