Accumulation of blood in the auricle of the ear, which can cause swelling and pain. It often results from physical injury that, if repeated, can disfigure the external ear. The blood supply to the cartilage is impaired and new cartilage forms in the space made by the haematoma (a condition known as cauliflower ear). Urgent treatment, consisting of draining the haematoma of blood, injection of hyaluronidase in a local anaesthetic, and application of a firm pressure bandage, is needed to prevent permanent deformity. The ear can be protected from further damage by covering it with a few layers of two-way stretch strapping wrapped around the head.
