FRAMELESS NEURONAVIGATION IN MODERN NEUROSURGERY

A fundamental effort in neurosurgery is to reduce surgical trauma. Mic roneurosurgical technique combined with precise localization of lesion s, can minimize the invasiveness of neurosurgical procedures. This rep ort summarizes the utility of frameless neuronavigator systems and exa mines their value in reducing operative invasiveness. The basic princi ple of neuronavigation is the virtual linkage between digitized neuror adiological data and real anatomical structures, allowing an excellent three-dimensional orientation by real-time graphic-anatomic interacti on. As frameless graphic interactive neuronavigation is developed furt her, these devices should become an important component of the modern microneurosurgical armamentarium and reduce surgical morbidity.
