To present the benefits of the addition of a conjunctival flap when correcting lower eyelid retraction using an auricular cartilage graft.
An auricular cartilage graft was obtained either from the concha o the scaphoid fossa. When preparing the receiving bed, the conjunctival incision was made 2 mm below the inferior margin of the lower eyelid tarsus, therefore, a conjunctival flap arising from the inferior border of the tarsus was obtained. The cartilage graft was placed in the lower eyelid. The inferior border of the graft was sutured to the retractors and conjunctiva using absorbable sutures. The superior border was sutured to the inferior tarsus, so that de conjunctival flap covered the superior portion of the graft.
Fourteen patients underwent the surgical technique. No corneal complications were observed in the early or late postoperative period. Donor site complications were not encountered.
The confection of a conjunctival flap that lines the superior portion of an auricular cartilage graft in the lower eyelid provides protection against corneal postoperative complications until the graft is epithelized.
介绍在使用耳软骨移植物矫正下眼睑退缩时添加结膜瓣的益处。
从舟状窝的耳甲腔获得耳软骨移植物。在准备接受床时，结膜切口在下眼睑睑板的下边缘下方 2mm 处进行，因此，从睑板的下边缘获得了一个起源于结膜的瓣。将软骨移植物放置在下眼睑中。使用可吸收缝线将移植物的下边缘缝合到牵引器和结膜上。上边缘缝合到下睑板，使结膜瓣覆盖移植物的上部分。
14 名患者接受了手术技术。在早期或晚期术后均未观察到角膜并发症。未发生供体部位并发症。
在眼睑下部的耳软骨移植物的上部分制作结膜瓣可提供保护，防止角膜术后并发症，直到移植物上皮化。
