  • Abstract
  • Look Inside

We have applied the frameless navigation system (StealthStationTM) to various neurosurgical proceduresto examine its usefulness. The system consists of a UNIX based workstation that creates triplanar and 3-dimensional images; an infrared optical digitizer with camera array; a reference-light-emitting diode(LED) array (e.g., reference array); and pointer probe modified by the addition of LEDs. This systemwas used to assist in placing a minimal skin incision and craniotomy in 4 cases, to determine thetumor/brain interface in 2 cases, to target the subcortical lesion in one case, and to correlate bony structurewith a skull base tumor in 3 cases. The combined use with magnetic source imaging of the somatosensorycortex allowed a fast orientation of eloquent areas in 2 cases with peri-Rolandic tumor. This system, thus,was proved to be a useful adjunct to open-tumor biopsy or resection.
