<unk>  or hematoma auris or perichondrial hematoma is a condition most common among wrestlers, rugby players, mixed martial artists, and 1920s boxers. If the external portion of the ear suffers a blow, a blood clot or other fluid may collect under the perichondrium. This separates the cartilage from the overlying perichondrium that is its source of nutrients, causing the cartilage to die. When this happens, the outer ear becomes permanently swollen and deformed, thus resembling a<unk> .
Headgear that protects the ears is worn in wrestling, many martial arts and other contact sports to help prevent this condition.
