脱细胞异体真皮与自体表皮复合移植修复创面

目的　研究应用脱细胞异体真皮与自体表皮复合移植修复创面的临床效果。　方法　 2 0 0 0年 7月～2 0 0 2年 8月 ,应用脱细胞异体真皮与自体表皮构成的复合皮对 34例头颈、躯干及四肢等部位的创面进行修复 ,创面最小5 cm× 10 cm,最大 12 cm× 19cm,其中陈旧性肉芽创面 2例 ,巨大色素痣切除创面 4例 ,皮肤广泛毛细血管瘤切除后创面 6例 ,瘢痕切除后创面 2 2例。观察移植皮片的成活率及愈后皮片色泽、功能情况。　结果　临床应用 34例 ,术后移植复合皮全部成活 ,30例获 3个月～ 2年随访 ,移植皮片颜色与周围正常肤色接近 ,皮片柔软 ,瘢痕增生不明显 ,功能改善显著。　结论　脱细胞异体真皮与自体表皮复合移植较单纯自体表皮移植后 ,皮片质量及关节部位功能上均有明显改善 ,尤其适合于四肢创面修复。

CLINICAL APPLICATION OF ACELLULAR ALLOGENIC DERMIS WITH AUTOGENOUS EPITHELIUM IN WOUND REPAIR

OBJECTIVE: To observe the clinical effect of acellular allogenic dermis with split-thickness autogenous skin graft for coverage of wound. METHODS: Acellular allogenic dermis with split-thickness autogenous skin graft was used to repair 34 wounds of head, neck, trunk and extremities. The area of wounds was from 5 cm x 10 cm to 12 cm x 19 cm. Out of 34 wounds, there were 2 due to old granulation, 4 due to excision of giant pigmented nevus, 6 due to excision of capillary hemangioma of skin and 22 due to excision of scar. RESULTS: All grafts survived and had the smooth surface without obvious pigmentation and with slight wound contraction. CONCLUSION: Acellular allogenic dermis with autologous epithelium for coverage of various wounds is an ideal procedure.
