Abstract
Keloids and hypertrophic scars are fibroproliferative disorders of the skin caused by abnormal wound healing and are characterized by chronic inflammation. Local risk factors for keloids and hypertrophic scars include 1. cyclical tension, 2. inadequate moist condition, 3. foreign body and allergic reaction, and 4. infection. It has been suggested that these factors cause persistence of inflammation. It is important for both the physician and patient to understand treatments for the reduction of mechanical forces and inflammation. In this paper, we discuss therapies for reduction of mechanical forces including 1. improvement of tension reduction sutures, 2. Z-plasty, 3. small wave incision, 4. core excision method, 5. reconstruction using flaps, and 6. stabilization using gel sheet or tape as therapies. We also discuss therapies for reduction of inflammation including 1. postoperative radiation therapy, 2. radiation monotherapy, 3. laser treatment, and 4. corticosteroid injection tips.
