The first evidence of surgery is trepanned skulls from the stone age. Some adults had holes cut in their skulls. At least sometimes people survived the 'operation' because the bone grew back. We do not know the purpose of the 'operation'. Perhaps it was performed on people with head injuries to release pressure on the brain.
Other documented examples of cosmetic surgery in the ancient world include the Egyptians, where basic cosmetic surgery was performed. The Romans used simple cosmetic surgery to repair war wounds, such as damaged earlobes.
