Repeated ear trauma - either actual blows to the ear, but (more likely in grappling) getting your ear smashed over and over again. This trauma causes the cartilage to separate from the overlying tissue of the ear. If the tissue isn't reconnected, the cartilage swells and malforms due to lack of nutrients (which can't be supplied by the now-disconnected tissue).How do you get it from BJJ? Is it from chokes mainly?
