A new concept for elevating a switch flap from the lower eyelid and then closing the defect is advocated. This flap is composed of two different-sized lamellae, the horizontally extended anterior lamella and the conventional wedge-shaped posterior lamella and lid margin. The donor's defect is to be closed with each lamella; the posterior lamella is horizontally advanced and directly closed with the aid of lateral canthotomy and cantholysis, and the anterior lamella is closed directly by extending the incision laterally to the temporal region and advancing the skin superolaterally. The switch flap can be applied to previously unindicated, nontypical upper eyelid defects by means of the split lamella concept and procedure. An illustrative case is presented.
本文提倡一种新的概念，即从下眼睑掀起一个转换皮瓣，然后关闭缺损。该皮瓣由两个不同大小的板层组成，水平延伸的前板层和传统的楔形后板层及睑缘。供区缺损由每个板层关闭；后板层水平推进，并借助外眦切开术和眦松解术直接关闭，前板层通过将切口向外侧延伸至颞区并将皮肤向上外侧推进而直接关闭。通过分层板层的概念和操作，转换皮瓣可应用于以前未涉及的非典型上睑缺损。本文展示了一个典型病例。
