The pinna, because of its exposed and protruding position, is frequently traumatized. Blunt injury may lead to formation of an auricular haematoma. The haematoma typically form in the subperichondrial plane. If treatment is delayed, the haematoma may dissect along the subperichondrial plane and result in unsightly deformity. Thus auricular haematoma need to be evacuated promptly and pressure dressing applied to conform with the shape of the pinna by means of through and through stitches. A prophylactic course of antibiotics is indicated to minimize secondary infection.
