They Drilled a Hole in the Living Skull, and the Patient Lived

Trepanation, the history of the oldest surgery on Earth: cutting a hole in the living skull, from Neolithic times through Hippocrates and Galen to the Renaissance. This is that history, told soberly. I'm Dr. Hollis, a retired coroner and pathologist. In this one I walk you, carefully and with respect for the people it involved, through trepanation, or trephination: the deliberate opening of the living skull, one of the oldest surgical procedures known, practised on nearly every inhabited continent. We look at the astonishing archaeological evidence, the many prehistoric skulls whose smoothly healed bone margins prove the patient survived, sometimes for years, long before anaesthesia or germ theory. We cover the tools, from worked flint and the bow drill to the crown-shaped trephine, the teaching of the Hippocratic writings and of Galen on head wounds, and how the operation persisted into the medieval and early-modern age, done to relieve pressure, and also for epilepsy, headache and to let out bad humours or spirits. The inversion at the heart of it: a crude version had a real, occasional rationale, relieving pressure from a bleed or a depressed fracture, the ancestor of a modern emergency operation, yet for most of its history it was done for reasons we now reject, and people survived it for millennia. Accuracy is the point. Where a claim is contested, I say so out loud: why the earliest people trepanned is genuinely unknown and debated, and the survival figures are estimates, not settled numbers. This is history, not medical advice. Nothing here is health guidance, a recommendation, or a how-to of any kind. It is the story of the oldest operation we know, and of why we very nearly stopped.

Sources and further reading: On trepanation, also called trephination, cutting, scraping or drilling an opening through the vault of the living skull, as one of the oldest known surgical procedures, evidenced from the Neolithic and found on nearly every inhabited continent. On the many recovered prehistoric trepanned skulls whose healed, remodelled bone margins indicate the person survived, sometimes years, before anaesthesia or germ theory, with some studied assemblages, such as sites in ancient Peru, reporting strikingly high proportions of healing; exact survival rates are estimates and remain debated. On the techniques of scraping, grooving, boring, and the circular crown-shaped saw known as a trephine, sometimes worked with a bow drill. On the Hippocratic Corpus of ancient Greece and on Galen in the second century, who wrote on head wounds and skull surgery. On the persistence of the operation through the medieval and early-modern era for depressed fractures and head wounds, and also for epilepsy, headache and to release supposed humours or spirits. On the one defensible rationale, relieving raised pressure from bleeding or a depressed fracture, which overlaps with modern emergency neurosurgery. On the genuine and unresolved debate over why the earliest people trepanned, whether for head trauma, epilepsy, headache, or ritual and spiritual purposes. Several figures and attributions are commonly cited estimates and remain debated. The people in this story are treated with dignity, not as spectacle.
