Answer:
A large hematoma of the ear should be drained with a large-bore needle or small stab incision and several minutes of pressure should be applied to achieve hemostasis and remove any remaining blood. A pressure dressing should then be applied with follow-up in case repeat draining is necessary. If an undrained hematoma is subperichondrial, the new cartilage formation below the elevated perichondrium can result in permanent ear deformity ("cauliflower ear").
