New discoveries in Peru reveal the possibility of the Inca skull surgery

More than 800 skulls found in Peru show the bone drilling signs with some holes. Researchers believe that Inca's surgeons have improved their technique over 2000 years.

Thousands of years before anesthesia techniques and accurate medical devices were born, humans performed complicated surgeries. In it, the most horrible is the skull drill - some parts of the skull will be shaved, cut or drilled to treat all problems from headaches, or devil-related injuries.

Hundreds of prehistoric skulls with drilling errors have been found in Peru, dating from 400 BC. Although prehistoric methods are rudimentary, researchers suggest that ancient anatomists are experts in skull surgery. In the Inca Empire era, the survival rate when performing a human skull surgery was twice that of the American Civil War!

In the time of the Inca Empire, the survival rate when performing cranial surgery was very high.

According to a new study published in World Neurosurgery, more than 800 skulls were found in Peru's Andes plateau showing signs of skull drilling when one or more holes are cut in surgical form. arts on their heads.

While the skull surgery has been around the world before, experts say there is nowhere to get skull drilling techniques like in Peru. During the excavation process in the late 1800s and early 1900s, hundreds of skulls were found mainly in burial caves, more than the total number of skulls drilled worldwide combined.

According to the researchers, sanitation issues have certainly played an important role in the success of skull surgeries. And for nearly 2000 years, these ancient anatomists have improved their techniques to only cause as little injury as possible.

Contrary to that, surgeons in the US Civil War frequently used non-sterile instruments and examined open wounds with their bare hands.

The ancient surgical instruments have been focused on hygiene.

Researchers were able to assess patients' survival ability based on evidence of recovery; In the absence of signs of healing, they assumed that the patient died during or immediately after the surgery.

According to researchers, ancient Peruvians have drawn experience without cutting the protective membrane of the brain. In the first years, the survival rate of brain surgery was not high - from about 400 to 200 BC, the rate was lower than in the American Civil War.

But things have changed rapidly after a few centuries. From 1000 to 1400 AD, the survival rate even increased to 91%. Throughout, the average survival rate is from 75 to 83%.
