Reconstruction of full-thickness upper eyelid defects often requires repair of both the anterior lamella (skin and orbicularis oculis muscle) and the posterior lamella (tarsus and conjunctiva). Various autogenous grafts have been used for posterior lamellar reconstruction, but it is still unclear which material is most suitable for repairing the posterior lamella. We report a patient in whom a subtotal defect of upper eyelid was reconstructed with a bipedicled myocutaneous flap lined by hard palate mucoperiosteum. We also examined tarsoconjunctiva, labial mucosa, hard palate mucoperiosteum, and auricular cartilage histologically and assessed the histologic features of these tissues as substitutes for the posterior lamella. An even and stable upper eyelid was formed by our method of reconstruction. A mucoperiosteal graft from the hard palate bears a close resemblance to the tarsoconjunctiva histologically because it contains both fibrous connective tissue and a mucous membrane. The graft took completely and there was no donor site morbidity or postoperative complications. A hard palate mucoperiosteal graft may be an optimal substitute for the posterior lamella of the upper eyelid.
全层上睑缺损的修复通常需要修复前层(皮肤和眼轮匝肌)和后层(睑板和结膜)。各种自体移植物已被用于后层重建,但哪种材料最适合修复后层仍不清楚。我们报告了一例用上腭粘骨膜衬里的双蒂肌皮瓣重建上睑大部缺损的患者。我们还对睑板结膜、唇黏膜、上腭粘骨膜和耳软骨进行了组织学检查,并评估了这些组织作为后层替代物的组织学特征。通过我们的重建方法形成了一个均匀稳定的上睑。来自硬腭的粘骨膜移植物在组织学上与睑板结膜非常相似,因为它既含有纤维结缔组织又含有黏膜。移植物完全成活,供区无并发症或术后并发症。硬腭粘骨膜移植物可能是上睑后层的最佳替代物。
