The Harappan skull indicates,"trepanation"surgical practice done 4300 years ago in India.
Scientists at the Anthropological Survey of India claim 
to have found evidence of an ancient brain surgical practice on a Bronze
 Age Harappan skull. 
The skull, believed to be 
around 4,300 years old, bears an incision that indicates an “unequivocal
 case” of a surgical practice known as trepanation, says a research 
paper published in the latest edition of Current Science. India is the place where plastic surgery was invented and Shushrut -Samhita was a surgical book describing many methods of surgery.
Trepanation,
 a common means of surgery practised in prehistoric societies starting 
with the Stone Age, involved drilling or cutting through the skull 
vault, often to treat head injury or to remove bone splinters or blood 
clots caused by a blow to the head. 
Other instances
While
 evidence of the practice has been found from regions in Peru, Europe 
and Bronze Age Jericho of Palestine, this is the first time the 
trepanation has been found in the Harappa civilisation. 
According
 to the research paper, a trepanated hole was found in a Harappan male 
skull that had been kept in the Palaeoanthropology Repository of the 
Anthropological Survey of India in Kolkata. 
There is evidence 
too of healing, “indicating that the victim survived for a considerable 
time after the operation,” the paper adds. “Scholars have recorded 
striking similarities in trepanation techniques across the continents, 
and therefore consider it as important evidence for prehistoric 
movements of people and for transfer of surgical skills from one society
 to another,” the authors say.
