脱细胞异体真皮复合移植修复皮肤缺损78例报告

目的：分析脱细胞异体真皮复合移植的效果。方法：对10例皮肤软组织撕脱伤创面，23例烧伤病人肢体痂创面，45例整形病人疤痕，切除后创面施行“脱细胞异体真皮＋自体表皮”复合移植，共78例次，结果：78例病人中有69例所植的复合皮片全部成活，余9例所植复合皮片部分成活，功能及外观恢复满意。结论：脱细胞异体真皮复合移植后具有良好的组织弹性，耐磨性，是理想的皮肤替代物，它既能保证获得如较厚皮片移植的外观及功能上的效果，又能减少供皮区疤痕的产生，对皮肤撕脱伤创面及大面积深度烧伤切削痂后的创面起到很好的替代真皮，减少疤痕挛缩，恢复功能的作用。

The Repair of Skin Defect by Acellularallodermis Complex Graft

Objective To investigate the effects of acellular allo-dermis for repairing skin defects in clinic.Methods A total of 78 cases were studied in this article. All of these patients were treated by acellular allo-dermis plus autologous epiderm skin complex grafts. Among these patients, 10 patients were injuried with skin,and soft tissue avulsion, 23 patients with limbs eschar wounds caused by burn,and after scar excision,45 patients with wounds undergoing plastic operations. Results 78 cases had satisfactory effects in appearance and functions. The complex skin grafts of 69 cases among all the 78 cases were alive. The complex skin grafts of the other 9 cases were partially skin sheet alive. Conclusions Acellular allo-dermis is an ideal skin surrogate, it has good tissue elasticity and tolerance. It can not only ensure the appearance and functions similar to thicker skin graft, but also reduce scar produce in donor site.
