It is generally believed that large eyelid defects must be repaired using a vascularized flap for 1 lamella, while the other can be a free graft. Recent studies indicate that the pedicle of a tarsoconjunctival flap does not contribute to blood perfusion. The purpose of this study was to explore whether large eyelid defects can be repaired using a free bilamellar eyelid autograft alone.
Ten large upper and lower eyelid defects resulting from tumor excision were reconstructed using bilamellar grafts harvested from the contralateral or opposing eyelid. Revascularization of the flap was monitored during healing using laser speckle contrast imaging, and the surgical outcome was assessed.
The functional and cosmetic results were excellent. All grafts survived and there was no tissue necrosis. Only 1 patient underwent revision after 4 days as the sutures came loose. Two patients developed minimal ectropion but needed no reoperation. All patients were satisfied with the surgical results. Perfusion monitoring showed that the grafts were gradually revascularized, exhibiting 50% perfusion after 4 weeks and 90% perfusion after 8 weeks.
A free bilamellar eyelid graft appears to be an excellent alternative to the tarsoconjunctival flap procedure in the reconstruction of both upper and lower eyelid defects, especially in patients who cannot tolerate visual axis occlusion or the 2-stage procedure of the conventional staged flap procedure.
人们普遍认为,大面积眼睑缺损必须使用带血管的皮瓣修复 1 层,而另 1 层可以使用游离皮片移植。最近的研究表明,睑板结膜瓣的蒂部并不参与血供。本研究旨在探讨是否可以单独使用游离双层眼睑自体移植物修复大面积眼睑缺损。
10 例因肿瘤切除导致的上下眼睑大面积缺损,采用对侧或对侧眼睑的双层移植物进行重建。使用激光散斑对比成像监测皮瓣的再血管化过程,并评估手术结果。
功能和美容效果均极佳。所有移植物均存活,无组织坏死。仅 1 例患者在 4 天后因缝线松动而需要再次手术。2 例患者出现轻微的眼睑外翻,但无需再次手术。所有患者对手术结果均满意。灌注监测显示,移植术后 4 周时灌注 50%,8 周时灌注 90%。
游离双层眼睑移植物似乎是修复上下眼睑缺损的一种极好的替代方法,尤其是对于那些不能耐受视轴阻塞或传统分期皮瓣手术 2 期手术的患者。
