TEHRAN The first surgery on human brain in Iran was done 4,800 years ago, according to studies made on the skull of a 13 or 14 years old girl, discovered in southeastern Iran. Scientific researches and medical studies conducted on the skull show that the patient suffered from hydrocephaly. The skull was discovered in a mass grave in Shahr-e Soukhteh (burned city) located in the vicinity of Zabol, Sistan-Baluchestan Province. In order to reduce the pressure inside the girl's brain, the surgeons had to remove part of her right parietal bone.

By doing that, they succeeded in temporary treatment of the girl, the studies said. According to the indications, the patient could live for six more months after the surgery. The mass grave discovered in Shahr-e Soukhteh is one of the oldest in its kind ever found in Iran. (IRNA)
