目的：介绍在使用耳软骨移植矫正下睑退缩时附加结膜瓣的优点。方法：取耳甲或舟状窝软骨移植。当准备接收床时，在下眼睑睑板下缘下方2 mm处做结膜切口，因此，获得了从睑板下缘产生的结膜瓣。将软骨移植物置于下眼睑。使用可吸收缝线将移植物的下缘缝合到牵开器和结膜上。将上级缘与下睑板缝合，使结膜瓣覆盖移植物的上级部分。结果：14例患者接受了手术技术。在术后早期或晚期未观察到角膜并发症。未发生供体部位并发症。结论：在下眼睑耳廓软骨移植物的上级部分衬上结膜瓣的形成提供了对角膜术后并发症的保护，直到移植物上皮化。
Purpose: To present the benefits of the addition of a conjunctival flap when correcting lower eyelid retraction using an auricular cartilage graft. Methods: 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. Results: Fourteen patients underwent the surgical technique. No corneal complications were observed in the early or late postoperative period. Donor site complications were not encountered. Conclusions: 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.
