目的 观察改良皮肤牵张技术在下肢皮肤缺损治疗中的应用效果。方法 2014年1月至2017年6月,15例患者应用皮肤牵张技术关闭下肢皮肤缺损创面,缺损面积为5 cm×4 cm～22 cm×11 cm。结果 所有创面一期关闭或一期延迟关闭。术后随访6～12个月,所有患者缺损愈合良好,瘢痕隐蔽,功能良好。结论 改良皮肤牵张技术利用皮肤组织的生物力学属性及机械蠕变特性,为下肢中等至较大皮肤缺损提供了一种安全有效的治疗方法,是传统皮瓣及皮片移植外的一种新选择。

Objective To explore the effect of modified skin-stretching technique in the treatment of skin defects in lower limbs.Methods From January 2014 to June 2017,15 patients utilized one or two skin-stretching device for the closure of the skin defect ranged from 5 cm×4 cm to 22 cm×11 cm in thigh(n=5)and lower legs(n=10).Results All patients achieved primary or delayed primary closure.The patients were followed up for 6 to 12 months,the defect healed well with concealed scar and good function.Conclusion The modified skin-stretching technique provides a safe and effective method for the treatment of moderate to large skin defects in the lower extremities by utilizing the biomechanical properties and mechanical creep properties of skin,and provides a new option for clinicians in addition to traditional skin graft and free flap transplantation.
