To overcome the insufficiency of donor tissue for repairing a large postburn defect.
The donor site was pre-expanded with an external expansion device in 54 clinical cases.
The expansion process was uneventful. The external expansion had delay effect that enabled the flap to be transferred with greater length to width ratio. After external expansion, the donor site of a flap or skin graft could be closed directly. The recipient and donor sites healed simultaneously.
External expansion is a practical method to provide 'extra' skin for reconstruction of a large skin defect.
克服修复大面积烧伤后缺损时供区组织不足的问题。
54例临床病例中，采用外部扩张装置对供区进行预扩张。
扩张过程顺利。外部扩张具有延迟效应，能使皮瓣以更大的长宽比进行转移。外部扩张后，皮瓣或皮肤移植的供区可直接闭合。受区和供区同时愈合。
外部扩张是为大面积皮肤缺损重建提供“额外”皮肤的一种实用方法。
