Application of the ISG Viewing Wand in Skull Base Procedures
Tumors arising from or attached to the skull base shift little during surgical removal and are therefore well suited to interactive image-guided surgical techniques. However, most skull base surgical procedures are done without interactive image guidance, as is true at our institution. We have had experience with 16 cases in which the ISG/Elekta Viewing Wand was used during surgery on a skull base tumor; some of these cases were gathered from a prospective trial in which the utility of the system was assessed by the surgeon. Given the number of variables influencing the duration and outcome of each skull base case, “randomized” studies seem inappropriate. We review here some of the technical considerations for use of the Viewing Wand during skull base surgery in general, present some representative cases from our own institution, and discuss selected papers from the literature evaluating image-guided techniques for skull base surgery.
