Chinese mummy suggests brain surgery was carried out 3,600 years ago
A three-and-a-half-millennia-old skull has uncovered evidence of an early form of brain surgery. The mummified woman’s perforated skull was discovered in the Xiaohe tomb in China’s Xinjiang Uygur Autonomous Region.
Experts said that the hole, which measures around 2 inches (50mm) in diameter, was most likely an early form of craniotomy. The amount of skull removed depends on the type of surgery being performed, and the flap is later replaced using screws.
It may have also been a form of trepanation, which involves the removal of a piece of bone from the skull. This procedure has been performed since prehistoric times, and cave paintings indicate that ancient people believed the practise would cure epileptic seizures, headaches and mental disorders.
Lead archaeologist Zhu Hong who made the discovery said: ‘[The wound] suggests the female, who died in her 40s, must have lived for at least a month, or even longer, after receiving the surgery.’
He added there were also signs of healing tissues around the wound. The mummy dates back to 1,615 BC and is one of the hundreds discovered in the Xiaohe ‘Little River’ Tomb complex.
Lying 108 miles (175 km) west of the ancient city of Loulan, the site was first explored in 1934 by Swedish archaeologist Folke Bergman, but not fully excavated until 2005.
Dating of the area has shown it goes back to approximately 2,000 BC, although tests have revealed the bodies contain DNA from the east and west.
In particular, males were found to have chromosomes typically found in Northern and Eastern Europe, alongside DNA found in Siberia. The mᴀssive burial site has more than 330 graves and contains the largest number of mummies ever found in the world.
These tombs include adults and children as well as 15 intact mummies, although approximately half of the tombs were said to have been looted by grave robbers.
The majority of the coffins found on the site were made of wood, and were shaped like boats, buried upside down. This practice is similar to how the Egyptians believed boats would take Pharaohs to the land of the ‘Gods’
Clothes and jewellery found in the tomb were also buried alongside the mummies, in small baskets, and the bodies were wrapped in cowhide and wool.
This prevented sand from getting inside the corpses. In addition to the wood coffins, four clay-covered rectangular coffins were also found, surrounded by stakes.
And six of the coffins were found to contain wooden ‘bodies’, rather than corpses. Each of these wooden sculptures was the same shape and were designed to look like males. Sєxual iconography was everywhere at the site, with posts representing phalluses and vulvas placed in front of each grave.
Sientists recreated ancient brain surgery to understand medical techniques that existed almost 2,500 years ago. A team of experts in Russia spent the past year examining skulls found with intricate surgical holes in a bid to fathom out how early nomadic doctors carried out their work.
Evidence suggested they were among the earliest ever examples of trepanation – the oldest form of known neurosurgery – with the procedures skillfully carried out. The oldest samples of skulls with boreholes drilled into them were found in a burial site in France dating back to 6500 BC.
But it was also used by the Ancient Egyptians, Chinese, Indians, Romans, Greeks and the early Mesoamerican civilisations. Even the ‘father of medicine Hippocrates advocated the process in his 400 BC tome ‘On Injuries of the Head’.
The procedure was carried out by Aleksei Krivoshapkin according to ancient methods used in the Altai Mountains on the skull of a woman who had died of natural causes shortly before.
Analysis of the skulls of ancient patients found that the operations were carried out with only one tool, a bronze knife, with the surgeons, carefully scraping at the skull, yet leaving behind only minimal traces of their work.
