摘　　要：目的采用单腔双扩张器重叠扩张术提高皮肤软组织扩张效率,修复皮肤缺损。方法2003年6月~2005年3月,采用重叠扩张术,将传统的单腔单囊扩张变为在同一个皮肤软组织腔隙内重叠埋置2个扩张器进行皮肤软组织扩张,治疗5例皮肤缺损患者。其中男3例,女2例。年龄11~28岁。前臂瘢痕2例,黑毛痣1例;瘢痕性秃发2例。病程1.5~24年。皮肤缺损范围12cm×5cm^13cm×12cm。重叠置入均采用椭圆形上200ml、下250ml的扩张器。重叠扩张区域实际注水量480~685ml。患者均采用扩张皮肤一次修复皮肤缺损区域。结果5例患者均顺利完成预定的皮肤软组织扩张且一次修复皮肤缺损区域,扩张器扩张时间为27~50d,重叠扩张区域扩张皮肤13.0cm×6.0cm^14.5cm×9.0cm。术后供、受区创面均期愈合,经3~15个月随访,扩张皮肤无收缩与色素沉着,未见瘢痕复发,外观修复均满意。结论重叠扩张术可明显提高皮肤软组织扩张效率,适用于皮肤缺损边缘可扩张皮肤有限、或不便于过多剥离而又需足够多的扩张皮肤修复的区域。Objective To improve the efficiency of skin soft tissue expansion with the overlapping tissue expansion techniques. Methods From June 2003 to March 2005, 5 cases of skin soft tissue defects were treated with the overlapping tissue expansion technique-two overlapped expanders in one soft tissue pocket, which was different from the traditional technique one expander in one soft tissue pocket. Five patients included 3 males and 2 females, aging from 11 to 28 years. The defect was caused by scar of forearm in 2 cases, by melanotic nevus in 1 case and by cicatricial baldness in 2 cases. The disease course was 1.5 to 24 years. The defect size ranged from 12 cm×5 cm to 13 cm×12 cm. Results Skin expansion process was satisfactory and skin defect was completely repaired with the expanded skin tissue in one operation in 5 cases. After operation, the wound of donor-recipient site healed by first intention. All patients were followed up from 3 to 15 months, no contracture, pigmentation and scar occurred at the expanded skin area. The long-term appearances were satisfactory. Conclusion Compare with the traditional tissue expansion techniques, the new overlapping tissue expansion techniques can apparently improve the efficiency of skin soft tissue expansion. It is suitable for the patients whose expandable skin is limited or no more skin tissue can be dissected near the skin defect and who need more expandable skin to repair skin defect.
