Pinna Contusion and Hematoma

Blunt external ear trauma may cause a contusion or hematoma of the pinna which, if untreated, may result in cartilage necrosis and chronic scarring or further cartilage formation and permanent deformity or "cauliflower ear." Open injuries include lacerations (with and without cartilage exposure) and avulsions.

Pinna Contusion. Contusion without hematoma is present. Reevaluation in 24 hours is recommended to ensure a drainable hematoma has not formed.

Pinna Hematoma. A hematoma has developed, characterized by swelling, discoloration, ecchymosis, and fluctuance. Immediate incision and drainage or aspiration is indicated, followed by an ear compression dressing.
