The medial epicanthal fold is a common ethnic trait in East Asian faces, and there is a significant demand for its correction for cosmetic reasons. Numerous epicanthoplasty techniques have been proposed; however, visible scarring and unnatural canthal shapes have been challenges. This study aimed to introduce a simpler approach for medial epicanthoplasty to address these issues and evaluate its outcomes.
From January 2020 to October 2023, 199 patients who were followed up for more than 6 months and had no history of prior medial epicanthoplasty were included in the study. The intercanthal distance (ICD) was measured from preoperative and recent medical photographs, and the ratio of the ICD to the corneal diameter was calculated for magnification correction. Postoperative complications and patient-reported aesthetic outcomes were evaluated.
The medial epicanthoplasty techniques used were the elliptical excision method in 94 patients and the mini-redraping method in 105 patients. The average follow-up period was 10.8 months. The ICD measurements demonstrated a statistically significant reduction after surgery in both groups. In the elliptical excision group, 14 patients (14.9%) reported dissatisfaction with their surgical outcomes. Two patients had prominent medial vertical scars, and 12 patients reported undercorrection. In the mini-redraping group, only 4 patients reported dissatisfaction with the surgical outcome (3.8%), all owing to undercorrection. No significant postoperative complications were observed in either group.
With the mini-redraping method, the medial epicanthal fold can be effectively addressed with minimal complications while achieving the natural shape and symmetry of both canthi in a straightforward manner.
内眦赘皮是东亚人面部常见的种族特征，出于美容目的对其进行矫正的需求很大。已经提出了许多内眦成形术技术；然而，明显的瘢痕形成和不自然的眦部形状一直是挑战。本研究旨在介绍一种更简单的内眦成形术方法来解决这些问题并评估其效果。
从2020年1月至2023年10月，纳入199例随访超过6个月且既往无内眦成形术史的患者。从术前和近期医学照片测量内眦间距（ICD），并计算ICD与角膜直径的比值以进行放大校正。评估术后并发症和患者报告的美学效果。
采用的内眦成形术技术中，94例患者采用椭圆形切除法，105例患者采用微型重睑法。平均随访期为10.8个月。两组术后ICD测量均显示有统计学意义的降低。在椭圆形切除组中，14例患者（14.9%）报告对手术效果不满意。2例患者有明显的内侧垂直瘢痕，12例患者报告矫正不足。在微型重睑组中，只有4例患者报告对手术效果不满意（3.8%），均由于矫正不足。两组均未观察到明显的术后并发症。
采用微型重睑法，可以有效解决内眦赘皮问题，并发症最少，同时能直接实现双侧眦部的自然形状和对称。
