Archaeologists find evidence of first ear surgery in 5,300-yr-old skull

Archaeologists have found a 5,300-year-old skull in Spain with evidence of the earliest ear surgery carried out in the world by humans. The skull that seemingly belonged to a middle-aged woman from Neolithic age had several cut marks visible around the left ear canal. Researchers said these marks point to mastoidectomy, a surgical procedure possibly performed to relieve ear pain.
