Blows and traumatic injury to the ears can be complicated by hematomas which can produce a cauliflower deformity as the cartilage framework is destroyed by the injury, the presence of the blood, the inflammatory response to the blood, and the scar tissue from the deposition of collagen in the injury field.  In addition, the cartilage must be protected from infection, and requires porper tissue coverage in order to heal well.  To achieve the best long term results, the hematoma must be evacuated, the blood cleared from the area of injury, and the perichondrium must be properly restored.  With the foundation restored, the overlying tissue layers can then be properly approximated to complete the repair.
