Herein a modification of the highly useful lateral tarsal strip procedure is presented. The refinement of the technique uses an oblique, vertically orientated, asymmetric, periosteal transposition (OVAPT) flap from the lateral orbital rim to fix the tarsal strip. From a consecutive series of 53 patients, A cohort of 49 procedures on 41 patients with a minimum of 3-month follow up is described. The procedure had a high rate of success in terms of canthal fixation over the median 14-month follow up. There was only one case of late stretching of the canthal repair in an anophthalmic orbit, one case of recurrent cicatricial ectropion due to an inadequate skin graft, and finally a case of early recurrent tarsal ectropion. The OVAPT flap further enhances the stability of the tarsal strip procedure, and allows greater control of lid position and tension. The pull is in a superior and lateral direction, mimicking that of the lateral canthal tendon.
本文介绍了一种对非常有用的睑板条手术的改良方法。该技术的改进采用了一种从眶外侧缘获取的倾斜、垂直定向、不对称的骨膜转位（OVAPT）皮瓣来固定睑板条。在连续的53例患者中，描述了对41例患者进行的49次手术，且至少随访3个月。在中位14个月的随访中，该手术在眦固定方面成功率很高。仅1例无眼球眼眶的眦修复出现晚期拉伸，1例因植皮不足导致复发性瘢痕性睑外翻，最后1例出现早期复发性睑板性睑外翻。OVAPT皮瓣进一步增强了睑板条手术的稳定性，并能更好地控制眼睑位置和张力。拉力方向为上外侧，模拟外眦韧带的拉力方向。
