耳后皮肤扩张法治疗耳轮瘢痕疙瘩

目的 为治疗耳轮瘢痕疙瘩提供一种较好的外科治疗方法。方法 手术分两期：第一期，在耳廓背侧及耳后乳突区皮下置入容量为50ml的肾形扩张器，定期向扩张器内注水行耳后皮肤扩张；第二期，约2个月后切除耳轮瘢痕疙瘩，取出扩张器，将耳后扩张皮瓣向耳轮推进，覆盖创面。术后无需其它辅助治疗。结果 2000年以来，采用本术式共治疗12例16只耳的耳轮瘢痕疙瘩，随访3个月～2年，让实效果满意，无复发，修复后的耳轮外形良好。结论 本术式以血运丰富的耳后扩张皮瓣，无张力修复耳轮瘢痕疙瘩切除后的创面，对耳后乳突区为正常皮肤条件下的耳轮瘢痕疙瘩提供了一种较为理想的治疗方法。

Treatment of helical keloid with retroauricular skin expansion

Objective To introduce a new technique for the treatment of helical keloid. Methods The procedure consisted of two steps.In the first step,a kidney-shaped expander of 50 ml was placed subcutaneously in the retroauricular area.Routine inflation with normal saline followed.In the second step,about two months afterwards,the expander was taken out and the helical keloid was excised.The expanded flap was advanced to cover the wound. Results The operation has been performed on 12 patients of 16 sites of helical keloid since 2000.Postoperative follow-up from 3 months to 2 years revealed satisfactory results.The reconstructed ear maintained a good contour. Conclusion The technique creates a retroauricular flap rich in blood supply,which can be used to close the defect left by helical keloid excision.It provides a good treatment for the helical keloid replaced with normal skin from the mastoid region.
