Ectropion is sometimes due to a shortage of skin of the lower lid (cicatricial) and may result from previous surgery, trauma, burns, skin diseases etc. Excessive exposure to the sun has also been incriminated. Vertical traction lines in the skin of the lower lid, accentuated by gazing up or by opening the mouth, suggest this condition. This paper describes the use of pedicle skin flaps rotated from the upper lid to treat cicatricial ectropion occurring in the absence of any predisposing factor and not responding to conservative treatment--that is, due to essential skin shrinkage. All 10 patients had an improved appearance, and epiphora persisted in only 1 patient, who subsequently underwent a punctum-enlarging procedure. In an 11th patient there was insufficient redundant upper-lid skin, so a free skin graft was used instead.
睑外翻有时是由于下睑皮肤短缺（瘢痕性）引起的，可能由先前的手术、创伤、烧伤、皮肤疾病等导致。过度暴露于阳光下也被认为是一个因素。下睑皮肤的垂直牵引线，在向上凝视或张口时会更加明显，提示这种情况。本文描述了使用从上睑旋转的带蒂皮瓣来治疗在没有任何诱发因素且对保守治疗无效的情况下出现的瘢痕性睑外翻——即由于原发性皮肤收缩所致。所有10例患者的外观均有改善，只有1例患者仍有溢泪，该患者随后接受了泪点扩大手术。第11例患者上睑多余皮肤不足，因此改用游离皮片移植。
