Double-eyelid surgery is one of the most common cosmetic surgeries performed in Asians. The palpebral marginal incision technique (PMIT) conceals the incision scar and creates natural-looking double-eyelids. However, the amount of eyelid skin removed by conventional PMIT is limited, which potentially results in an unnatural crease or inferior skin below the palpebral crease that appears swollen.
The aim of this study was to introduce a modified PMIT which creates scarless, dynamic, and natural double-eyelids with a limited amount of eyelid skin excision.
From January 2018 to December 2020, 382 patients (764 eyelids) underwent double-eyelid surgeries with the described technique. The key point was to form a pretarsal levator aponeurotic flap, acting as a soft motor transmission to bridge tarsus, orbicularis oculi muscle, and skin dermis. Satisfaction with the overall aesthetic outcomes-as assessed by surgeon and patients-and complications were postoperatively evaluated at various follow-ups.
The mean follow-up period was 7.6 months (range, 6-12 months). Of the patients, 332 (86.9%) reported self-assessment of outcomes as satisfactory and 37 (9.7%) as fair. Secondary operations were required for 13 (3.4%) patients for double-eyelid asymmetry or crease curve malformations. Early-stage hematoma (12 cases) and lagophthalmos (19 cases) were observed and completely recovered within 1 month.
Our modified PMIT technique was capable of achieving scarless and natural-looking double-eyelids with a biomimetic anatomic structure.
双眼皮手术是亚洲人最常进行的美容手术之一。睑缘切口技术（PMIT）隐藏切口疤痕，打造自然的双眼皮。然而，传统的 PMIT 切除的眼睑皮肤量有限，可能导致双眼皮折痕不自然或双眼皮线下方的皮肤肿胀。
本研究旨在介绍一种改良的 PMIT，该技术可通过有限量的眼睑皮肤切除，实现无痕、动态、自然的双眼皮。
2018 年 1 月至 2020 年 12 月，采用描述的技术对 382 例患者（764 只眼）进行了双眼皮手术。关键在于形成提上睑肌腱膜前叶额状瓣，作为软动力传输，连接睑板、眼轮匝肌和皮肤真皮。术后各个随访期，由医生和患者评估整体美学效果满意度和并发症。
平均随访时间为 7.6 个月（6-12 个月）。332 例（86.9%）患者自我评估结果满意，37 例（9.7%）认为效果尚可。13 例（3.4%）患者因双眼皮不对称或折痕曲线畸形需要进行二次手术。早期血肿（12 例）和睑裂闭合不全（19 例），均在 1 个月内完全恢复。
我们改良的 PMIT 技术能够实现无痕、自然的双眼皮，并具有仿生解剖结构。
