When the medial third of the upper or lower eyelid has to be reconstructed after full-thickness tumour excision, we usually use Hübner tarsomarginal grafts, but when medial canthal lesions spread to the medial orbital wall without invading the orbital margin, conchal graft becomes our first surgical option. Previously reported solutions to this difficult problem are few and concern more directly medial orbital wall fractures. We found no article dealing specifically with the use of conchal graft in post-ablative reconstruction of the medial orbital wall. Nevertheless the concha presents great advantages over bone grafting or rib cartilage, because it is more flexible and malleable. And it is less prone to extrusion or infection as may be allografts implants. It is a very effective way to repair medial orbital defects, but graft reorientation must be perfect to match exactly the medial orbital wall concavity.
当上睑或下睑的内三分之一在全层肿瘤切除后需要重建时，我们通常使用许布纳睑缘移植片，但当内眦病变蔓延至眶内侧壁而未侵犯眶缘时，耳甲移植片就成为我们的首选手术方式。此前针对这个难题报道的解决方法很少，且更多直接涉及眶内侧壁骨折。我们未发现专门论述耳甲移植片在眶内侧壁切除后重建中应用的文章。然而，耳甲相较于骨移植或肋软骨具有很大优势，因为它更柔韧且可塑性更强。并且它不像同种异体植入物那样容易发生排斥或感染。这是修复眶内侧缺损的一种非常有效的方法，但移植片的重新定向必须完美，以精确匹配眶内侧壁的凹陷。
