Although various techniques have been reported to correct blepharoptosis, undercorrection is still a commonly occurring complication and needs further revision procedure. Scar formation and distorted anatomy make reoperation more difficult than the primary surgery. However, tarsus is usually fully maintained in the first correction process, and this study combined tarsus resection with levator resection. The resected tarsus can offset the amount of levator excised, which makes this technique applicable for ptosis secondary revision. Fifty-nine patients with undercorrection complication were included who underwent secondary revision by combining excision of tarsus and levator muscle. The correction and symmetry results were evaluated and analyzed in different groups, which were based on patients' different primary correction techniques. Adequate correction can be achieved in 51 cases (86.4%). The patients who took frontalis suspension surgery in the first correction surgery showed higher adequate correction rate than patients who underwent levator-based technique in their primary surgery. In all patients, 43 cases (72.9%) achieved good or fair symmetry results. Combining excision of levator and tarsus is effective with respect to blepharoptosis reoperation, with better biomechanics and a satisfying aesthetic outcome. It provides a new method in limited secondary revision techniques.
尽管已有多种技术用于矫正上睑下垂,但矫正不足仍是常见的并发症,需要进一步的修复手术。瘢痕形成和解剖结构变形使再次手术比初次手术更困难。然而,在首次矫正过程中睑板通常能完全保留,本研究将睑板切除术与提上睑肌切除术相结合。切除的睑板可抵消提上睑肌切除的量,这使得该技术适用于上睑下垂的二次修复。纳入59例矫正不足并发症患者,他们接受了睑板和提上睑肌联合切除的二次修复手术。根据患者初次矫正技术的不同,对不同组的矫正和对称结果进行了评估和分析。51例(86.4%)可实现充分矫正。初次矫正手术采用额肌悬吊术的患者,其充分矫正率高于初次手术采用提上睑肌相关技术的患者。所有患者中,43例(72.9%)获得了良好或尚可的对称效果。提上睑肌和睑板联合切除术在上睑下垂再次手术中有效,具有更好的生物力学性能和令人满意的美学效果。它为有限的二次修复技术提供了一种新方法。
