NEURONAVIGATION
Neuronavigation is a techniqe now in common useage in neurosurgery.
The principle is very similar to satellite navigation, the map is a
patients own CT or MRI scan loaded onto a computer. The satellites
are an array of cameras able to see in 3D, and the navigation tool
is a surgical instrument visible to the cameras. This technology
allows real-time navigation during surgery of the brain or
spine.
We now have an additional system dedicated to pituitary surgery
that utilises electromagnetic navigation and thus does not need the
head to be fixed with pins.
This example shows
neuronavigation being used during a transsphenoidal operation for a
recurrent pituitary tumour.
Due to previous surgery, many of the anatomical landmarks that
allow a surgeon to safely fing the pituitary gland are
missing.
Use of neuronavigation allows a safe and quick exposure of the
pituitary tumor with a reduction in operative
complications.
