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.
瘢痕疙瘩和增生性瘢痕是由胶原蛋白过度沉积所致,其病因尚不清楚。与增生性瘢痕不同,瘢痕疙瘩常持续存在于损伤部位,切除后常复发,且总是超出原始伤口边界生长。已有许多控制瘢痕疙瘩的试验,但大多数都未成功。作者提出一种治疗瘢痕疙瘩的新手术技术,并将其命名为瘢痕疙瘩核心摘除术。他们从瘢痕疙瘩中切除内部纤维核心,并用由囊下血管丛供血的瘢痕疙瘩外皮瓣覆盖缺损处。作者用瘢痕疙瘩核心切除术治疗了24例耳部、躯干、面部和生殖器部位的瘢痕疙瘩。发生了4例部分皮瓣充血或坏死的情况。那些术后一期愈合的患者在随访期间未出现瘢痕疙瘩复发的迹象。作者发现瘢痕疙瘩核心摘除术在预防瘢痕疙瘩复发方面效果极佳,术后无需辅助治疗。
