5. Brain surgery
According to archaeologists, brain surgery has been performed since the late “Neolithic” period. Believed to go back about 5,000 years ago, the earliest known technique was trepanation, the removal of bone from the skull. However, an ancient tomb discovered in the French village of Ensisheim suggests that brain surgery was performed at least 7,000 years ago.
In 1997, an archaeologist working in Ensisheim discovered the remains of a 50-year-old man with two holes in his skull. There was a fracture in the skull, which they pointed out was caused by surgery and not by violence. Located in the frontal lobe, the first hole is about 6 cm wide, while the other holes at the top of the skull are about 3 cm wide. This suggests that the surgery took place at different times. The surgery must have been successful because both holes healed before he died. The small foramen is completely covered by a new layer of bone, and the large foramen is partially covered.
Although it is the oldest known evidence of brain surgery, archaeologists believe it is possible that brain surgery appeared even earlier. In fact, the trepanation was performed perfectly and the man survived.
