摘要
目的:总结大面积烧伤后期瘢痕畸形整形应用异体脱细胞真皮基质(ADM)+自体薄皮片复合移植的术后效果,为提高异体ADM移植的成功率提供临床经验。方法:2010年1月-2015年12月在大面积烧伤后期瘢痕整形手术中应用异体ADM与自体薄皮片复合移植201例,手术行瘢痕局部切除、挛缩松解,异体ADM覆盖于创面,四周缝线固定,其上以自体头部或其他部位薄皮片来覆盖,抗菌敷料外敷加压包扎或局部打包固定。术后观察创面情况和随访半年以上的治疗效果。结果:191例(95.02%)异体ADM与自体薄皮片复合移植区皮片成活较好,无疼痛和感染征象,术后6个月随访,复合皮移植区局部外观较好,质地柔软,弹性好,皮片无挛缩,无明显瘢痕形成,关节活动功能明显改善,但部分有色素沉着。10例(4.98%)患者,瘢痕位于口周、下颌或腋窝,术后1周左右创面局部有疼痛,术区敷料有异味,全身发热,自体薄皮片全部液化坏死,异体ADM部分失活、溶解脱落。结论:异体ADM与自体薄皮片复合移植是修复大面积烧伤后期瘢痕畸形的较好方法。
Objective To summarize the postoperative results of acellular allograft dermal matrix combined with autologous skin thin graft in the treatment of extensive post-burn scar deformity late application,provide clinical experience for improving acellular allograft dermal matrix graft success rate.Methods From January 2010 to December 2015,201 cases of large area post-burn scar plastic surgery were performed in patients with autologous thin skin graft and allograft acellular dermal matrix.Local excision of the surgical scar,contracture release,removal of allogenic acellular dermis matrix to cover the wound,around suture fixation,to autologous head or other parts of the thin skin graft to cover,antibacterial dressing external compression bandage or local packaged fixed.The treatment effect of the wound was observed after operation and the patients were followed up for more than half a year.Results In 191 cases(95.02%) allogenic acellular dermal matrix and autologous thin skin graft composite grafting regions skin graft survival better and no signs of pain and infection,after 6 months of follow-up,composite skin graft area local appearance better,soft texture,good elasticity,skin graft without contracture,no obvious scar,joint function improved significantly,but part of the pigmentation.10 cases(4.98%) patients,scar is located in around the mouth,jaw or axillary,about 1 week postoperation wound pain,surgical dressings have peculiar smell,body heat,razor thin autoskin all liquefaction necrosis,allograft dermal matrix partial inactivation,dissolved off.Conclusion Allograft acellular dermal matrix combined with autologous thin skin graft is a good method for the repair of large area post-burn scar deformity.
