Dedolatio, from dedolare, (de, and dolare, dolatum,) 'to cut and hew with an axe.' This word has been used by surgeons to express the action by which a cutting instrument divides obliquely any part of the body, and produces a wound with loss of substance. It is commonly on the head, that wounds by dedolation are observed. When there was a complete separation of portion of the bone of the cranium, the ancients called it Aposceparnismus.
