>Trepanation dates back to 7,000–10,000 years ago,[8] and it is perhaps the oldest surgical procedure for which there is archaeological evidence,[9] and in some areas may have been quite widespread.

At one burial site in France dated to 6500 BCE, 40 out of 120 prehistoric skulls found had trepanation holes.
