A new surgical treatment of keloid: keloid core excision

Keloids and hypertrophic scars result from excessive collagen deposition, the cause of which is not yet known. Unlike hypertrophic scars, keloids frequently persist at the site of injury, often recur after excision and always overgrow the boundaries of the original wound. There have been many trials to control keloids, but most of them have been unsuccessful. The authors propose a new surgical technique to treat keloids and name it keloid core extirpation. They excise the inner fibrous core from the keloid and cover the defect with a keloid rind flap, which is arterialized by the subcapsular vascular plexus. The authors treated 24 keloids of the ear, trunk, face, and genitalia with keloid core excision. Four cases of partial rind flap congestion or necrosis occurred. Those patients who healed primarily after surgery showed no evidence of keloid recurrence as long as they were followed. The authors have found the keloid core extirpation technique to be excellent in preventing keloid recurrence, with no adjuvant therapy after surgery.
