Removal of bone in cranial base image-guided surgery—performed in a clever and anatomically complex manner—reduces or even eliminates the need to disrupt healthy brain regions by moving them out of the way.
Skull base procedures, for example, may be designed to traverse the bone containing the ear (petrous bone), around the eye (orbit), through the nose or paranasal sinuses, low on the temple beneath the brain, or even upwardly directly from the neck region.
Fundamentally, these are minimally invasive techniques that afford the highest possible degree of tumor removal while preserving neurological function to the greatest extent possible.
