Neuronavigation
Science Daily
The Stealth Station computer then transforms the data into several three-dimensional images that are displayed on a high-resolution monitor in the operating room. On the computer screen, a red "X" pinpoints the location and movement of the instruments in real time. The Stealth Station is accurate to less than one millimeter.
The Zeiss-MKM System for Frameless Image-Guided Approach in Epidural Motor Cortex Stimulation for Central Neuropathic Pain
The mean spatial accuracy of distance between (MR) imaging-defined and actual central sulcus was 2.4 mm (range 5-10 mm). The intraoperative SSEP-defined central sulcus was close to that defined by MR imaging (mean distance 6.4 mm). Although very precise, intraoperative SSEP recordings were impaired by artifacts and wave attenuation in six of the 12 patients. Stereotactic correlations between anatomical and functional data in the navigation system corrected final targeting in 10 of 12 cases. Pain relief was obtained in eight patients.

wo 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.

omparing preoperative and intraoperative fiber tracking visualizes a marked shifting and deformation of major white matter tracts because of tumor removal. This shifting emphasizes the need for an intraoperative update of navigation systems during resection of deep-seated tumor portions near eloquent brain areas.
