Right, well, we all know that holes (from injury or disease) in a living human’s skull can be surgically repaired with a metal plate attached over the bone, and I’ve even seen a kid who had over _half_ his skull replaced with acrylic after a gunshot wound destroyed it (and the brain beneath).

My question is: how much of the skull, at maximum, could we replace with current medical technology, without killing the patient (whom I’d judge has been through enough already)? How much _has_ been replaced in a single person? Could you replace the entire cranial vault?
