ABSTRACT
The primary application of surgical navigation systems (SNSs) for intracranial use by most practitioners is likely to be fashioning minimal access craniotomies (MACs) for resection of primary and metastatic tumors (1-13). Knowing the precise location of an intracranial lesion along with vascular and cortical relationships may allow for very small cranial openings and minimize the need for intracranial exploration. Computer-assisted minimally invasive craniotomies appear to reduce neurological and wound complications as well as operative time and patient discomfort compared to traditional techniques (1,2,6,7,14).
