Inca Skull Surgeons Were "Highly Skilled," Study Finds

Inca Skull Surgeons Were "Highly Skilled," Study Finds: "Inca surgeons in ancient Peru commonly and successfully removed small portions of patients' skulls to treat head injuries, according to a new study.

The surgical procedure—known as trepanation—was most often performed on adult men, likely to treat injuries suffered during combat, researchers say.

A similar procedure is performed today to relieve pressure caused by fluid buildup following severe head trauma."
