Cranial trepanation in two skulls of early medieval Italy.

Cranial trepanation is a practice known since prehistory in various, often geographically distant populations. In this work are presented two early medieval trepaned skulls. The first skull comes from Canosa in Apulia (6th-7th c. AD; according to radiocarbon dating), the second is from Ticineto Alessandrino (5th-8th c. AD). The skull of Canosa shows a single perforation on the bregmatic quadrant of the right parietal, whereas the Ticineto skull presents three lesions of different shapes and sizes. Two perforations are on the left parietal and the other is on the right parietal. The lesions of the Ticineto skull can be referred to a therapeutic operation following a trauma, with survival of the individual. In the Canosa skull the absence of a healing reaction suggests a pathological process, without survival of the subject. Moreover, a particular ritual practice cannot be excluded (i.e. a post-mortem trepanation)
