摘要
目的提供一种修复体表大面积皮肤缺损的方法。方法Ⅰ期手术埋置扩张器时,在同一个组织腔隙内同时埋置两个扩张器。Ⅱ期手术取出扩张器,进行扩张皮瓣转移的同时,在皮瓣下再次重叠埋置扩张器。如此循环往复,直至大面积皮肤缺损被全部修复。结果共修复各种原因所导致的体表大面积皮肤缺损患者18例,连续扩张次数最少2次,最多9次,每例患者使用的扩张器最少8个,最多42个。除1例患者术后出现1组(2个)扩张器感染外,其余病例术后无血肿、感染、皮瓣坏死等并发症发生。随访时间为6～18个月,远期效果满意。结论扩张器重叠、连续扩张技术在保证扩张过程顺利进行的同时,可以最大限度地对皮肤进行扩张,缩短治疗时间,是一种较好的修复体表大面积皮肤缺损的方法。
Objective To provide a method for repair of large area skin defect. Methods Two expanders were buried overlapped in the same soft tissue pocket in the first-stage operation. The expanders were removed and the expanded skin flaps were transferred to repair partial defect in the second-stage procedure. The expanders were then re-buried under the expanded skin flaps at the same time. The same processes move in circles until the large area skin defect has been repaired completely. Results 18 cases of large area skin defects were treated with the method mentioned above. The minimal number of continued tissue expansion was two and the maximal number was nine. The minimal number of the expander used was eight and the maximal number was forty-two. There were no complications such as hematoma, infection and flap necrosis except one patient with infection of one group expander (two expanders). All cases were followed up and the time ranged from 6 to 8 months. The long-term results were satisfactory. Conclusion The overlapped and continued tissue expansion technique can not only guarantee the smooth carrying out of the expansion process, but also expand the skin maximally and shorten the treatment time simultaneously. It is a good method for repairing the large area skin defect.
