Ear cropping is the removal of part of the cartilage of the ear. It is done commonly to breeds of dogs such as boxers, and, far less commonly, to humans. In dogs, the purpose is to shorten the ear and make it stand up, whereas, in humans, the purpose is simply to reshape the ear.
While ear collapse is a risk, and infection is very much a possibility, aftercare is usually uneventful, and the wound heals normally by second intention. Ear tissue is usually removed with a scalpel and sealed using electrocautery or suturing.
