Structural and cosmetic outcomes of medial epicanthoplasty: An outcome study of three different techniques.

AIM

The authors intended to evaluate the structural and cosmetic outcomes of medial epicanthoplasty.

METHODS

Medical records and photographs of 92 eyes from 46 Korean patients who underwent medial epicanthoplasty were reviewed retrospectively. The patients underwent epicanthoplasty using root Z-plasty, Y-V plasty, Mustarde's technique, and modified one-armed Mustarde's technique, from January 2009 to August 2011. Postoperative changes in the horizontal fissure width were measured for the assessment of structural outcome. The cosmetic outcomes were assessed in terms of appearance, symmetry, and scarring using a three-point grading system. Postoperative outcomes were evaluated at 1, 3, and 6 months after surgery.

RESULTS

Root Z-plasty, Y-V plasty, and Mustarde's method (including Mustarde's technique and modified one-armed Mustarde's technique combined) with medial canthopexy were performed on 64, 13, and 15 eyes, respectively. Six months after surgery, the horizontal fissure width increased by an average of 1.74 (8.4%), 1.64 (8.9%), and 1.89 mm (12.9%), respectively (p < 0.001, 0.041, and 0.027). In addition, root Z-plasty had a higher postoperative appearance grade than Y-V plasty and Mustarde's method (p < 0.001). Grades of symmetry were good for all methods, and grades of scarring were good for root Z-plasty and fair for the others. Scarring was significantly improved until postoperative 6 months in root Z-plasty and Y-V plasty (p < 0.001 and p = 0.022, respectively).

CONCLUSIONS

Medial epicanthoplasty increased the horizontal fissure width of about 1.7 mm. Most cosmetic outcomes were satisfactory, with root Z-plasty resulting in excellent outcomes. Scarring faded over time.
