Not quite
This goes along with previously found remains of skulls with large, regular openings in them that had partially healed, leading to the inescapable conclusion that early civilizations practiced brain surgery.
It leads to no such inescapable conclusion. It does lead to the conclusion that early civilisations practiced trepanning, which has everything to do with making a hole to let the evil spirits out and nothing to do with brain surgery.
And they didn't "close the skull". The reason we know people survived the trepanning process is because the edges of the bone around the hole had started to heal.
Just the facts, ma'am :-)
