Description
Late 19th century or early 20th century medical study human skull. Has an odd cutout or hole on the side that reminds me of trepanning.
Trepanning, also known as trepanation, trephination, trephining or making a burr hole is a surgical intervention in which a hole is drilled or scraped into the human skull. Trepanning was a common surgical process from the Renaissance until the beginning of the 19th century, it was routinely used to treat head wounds, and into the 18th century (some speculate into the 19th century), it was used to treat epilepsy, mental disorders and spiritual cleansing.
