Abstract
The use of endoscopic techniques has gained significant popularity over the past decade.
The potential advantages of angled lenses to visualize around tight corridors without
retracting have proven to be an attractive feature. The limitation of endoscopy has
been the inability to obtain a true three-dimensional perspective for which microscopy
is ideal. Therefore we postulated that for complex intradural lesions the merger of
the two technologies would prove to be ideal. In this paper we report our experience
with simultaneous microscopy and endoscopy, using picture-in-picture technology, for
intracranial vascular and oncological surgery. We have found it useful to offer enough
visualization to allow for performing surgery and not just for inspection.
