Abstract
A fundamental effort in neurosurgery is to reduce surgical trauma. Microneurosurgical
technique combined with precise localization of lesions, can minimize the invasiveness
of neurosurgical procedures. This report summarizes the Utility of frameless neuronavigator
systems and examines their value in reducing operative invasiveness. The basic principle
of neuronavigation is the virtual linkage between digitized neuroradiological data
and real anatomical structures, allowing an excellent three-dimensional orientation
by real-time graphic-anatomic interaction. As frameless graphic interactive neuronavigation
is developed further, these devices should become an important component of the modern
microneurosurgical armamentarium and reduce surgical morbidity.
