目的:观察脱细胞异体真皮在烧伤后瘢痕整形手术中的临床应用效果。方法:在22例烧伤后瘢痕整形手术中,创面应用脱细胞异体真皮 自体刃厚皮片复合移植。结果:20例皮片完全成活,创面平整,皮片有光泽;2例成活90%,换药后创面愈合,遗留散在瘢痕。随访4~6个月,术区活动度好,皮片色泽与周围皮肤相似,色素沉着轻,未见明显瘢痕增生或挛缩。结论:脱细胞异体真皮是烧伤后瘢痕整形良好的覆盖与填充材料。

Application of acellular allogenic dermis in plasticity of postburn scar deformity

Objective: To observe the clinical effects of acellular allogenic dermis in plastic surgery of postburn scar deformity.Methods: In 22 cases plastic operation,the surface of wounds was covered by acellular allogenic dermis plus autologous epidermal skin graft,followed by bandaging and immobilization.Results: Growth of wound surface was favorable.20 cases showed the free skin graft completely survived,and wounds surface was smooth and lustrous.The 2 others showed 90% survived.After changed drug,wounds surface healed and remained a little scar.Followed up for 4-6 months,results could finding that the skin area was flexible,their colour and luster were similar to the circumambient skin,no obvious pigmentation.At the same time, scars hyperplasia or contracture also weren't found.Conclusions: Acellular allogenic dermis is an satisfactory coverage and stuffing material in the plastic surgery of postburn scar deformity.
