Objectives. To evaluate the advantages and limitations of the utilized
system in accordance with the operative indications of stereotactic
neuroendoscopy.
Patients and Methods. We reviewed our collective experience
of computer-assisted stereotaxy (frame-based and frameless) and virtual
endoscopy in neuroendoscopic surgery from 1982 to 2003.
Sterotactic guiding
systems (frame-based and frameless) have been used to perform more than 450
neuroendoscopic operations at our institute.
Results. Even though image
guidance is not essential in all cases, technological developments have
definitely been one of the major factors in improving outcomes.
Planning
endoscopic trajectory and intraoperative orientation within the ventricular
system or other cavities are the main indications for its application.
Conclusions. No surgical tool, no matter how accurate, can be a substitute
for thoughtful and methodical pre-operative planning.
Image-guided
technologies are applied in order to make endoscopic surgery safer, faster
and more easily reproducible.
Despite the high initial cost of the
equipment, overall expenses are expected to be reduced because of greater
operative efficiency and shorter hospital stay.
