"A new study by two American anthropologists now provides evidence that the Incas performed trepanation to treat head injuries; that the procedure was far more common than was previously thought; and that the Incan practitioners of trepanation were highly skilled surgeons with a detailed knowledge of the anatomy of the skull.... Of these 411 skulls, 66 exhibited perforations of varying shape and size. More than half were circular, but some were oval or irregularly circular, and one (above) was rectangular. The diameters of the circular holes ranged from approximately 0.3 - 7.3 cm. In all, 109 holes were observed in the 66 skulls, and there was one individual with 7 trepanations."
