Abstract：
This case report describes a novel surgical technique, the \"levator switch,\" for correcting severe blepharoptosis in a 65-year-old man with poor Bell\'s phenomenon following previous bilateral ptosis surgery. He presented with recurrent ptosis, weak levator function, and excessive frontalis muscle use. The technique involves a sequential approach: anterior levator resection followed by repurposing the resected tissue as a posterior lamellar graft to the lower tarsal border. This elevates the eyelid margin while maintaining a stable palpebral fissure height. The levator switch addresses ptosis from poor levator function and minimizes postoperative corneal exposure. It offers advantages over the existing tarsal switch procedure by preserving the tarsus and meibomian glands, thus maintaining eyelid stability and contour.
摘要：
这个病例报告描述了一种新颖的手术技术，提升器开关，“用于纠正一名65岁的男性在先前的双侧上睑下垂手术后出现严重的Bell现象。他出现了复发性下垂，提升机功能较弱，和过度使用额肌。该技术涉及顺序方法：前提提肌切除术，然后将切除的组织重新用作后板层移植物到下骨边界。这提高了眼睑边缘，同时保持稳定的睑裂高度。提上肌开关解决了由于提上肌功能不良而引起的上下垂，并最大程度地减少了术后角膜暴露。通过保留tar和睑板腺，它比现有的tar转换程序具有优势，从而保持眼睑的稳定性和轮廓。
