Invisible scar medial epicanthoplasty: A novel approach

Presently, many techniques have been described to make the epicanthal fold less prominent. However, visible scarring remains a major concern in most techniques. The aim of this study was to develop a novel design using concealed incisions with minimal tension.

Between December 2010 and May 2015, charts were reviewed from patients who underwent a concealed incision and tension-free technique to correct the epicanthal fold. The intercanthal distance (ICD), interpupillary distance (IPD), scar visibility, and cosmetic results were evaluated preoperatively and 1 year after the surgery. The ratio of the ICD to IPD (ICD ratio) was calculated, and the visibility of the scar was assessed.

In total, 136 patients (mean age 25.2 ± 2.7 years, range 20-32 years) were included. The preoperative median ICD ratio was 0.60 (range, 0.54-0.68) and decreased to 0.54 (range, 0.48-0.62) postoperatively. The median ICD ratio reduction was 9.1% (range, 3.6%-22.0%; P < 0.001, Wilcoxon signed-rank test). One hundred and thirty-four patients (98.5%) had no visible scarring or minimal scarring visible only under close inspection. Two patients (1.5%) experienced a more prominent scar, but none of them developed a severe scar requiring revision. The aesthetic outcome judged by the patient and surgeon was excellent or good in all cases.

From our experience, the scar after medial epicanthoplasty can be minimized by using a concealed incision and tension-free technique. Our technique is an effective and individualized method, leading to a high satisfaction rates.
