扩张薄皮瓣的临床应用

将软组织扩张术与薄皮瓣联合应用修复大面积缺损15例。对拟切除病变的周围正常皮肤软组织进行预扩张,在形成扩张皮瓣的同时剔除其上的部分脂肪组织,但完整保留皮瓣的真皮下血管网。本组扩张薄皮瓣最大长宽之比为4.3:1,I期愈合12例,延迟愈合3例。临床观察和初步实验结果显示皮瓣血供来自近端蒂部、创面基底与周缘。为修复组织缺损提供了一个方法。

Clinical application of expanded thin skin flap

Fifteen patients were treated with the expanded thin skin flaps with the large area defects of soft tissue resulting from scar, pigmented nevus, hemangioma, chronic ulcer and neurofibroma. The operative procedure includes tissue expansion and defatted flap transplantation. All flaps that preserved only a thickness of 3 mm adipose tissue or superficial fascia beneath the subdermal vascular network survived with the primary healing of 12 cases and the delay healing of 3 cases in the maximal ratio of length to width 4.3:1. The details of clinical experience and primary experiment were presented.
