Two-Z-epicanthoplasty in a three-dimensional model of Asian eyelids

Abstract

Background: Epicanthoplasty is a procedure currently available for medial epicanthus correction. However, potential problems such as difficult designs, undercorrection, and unpleasant scarring in the medial canthus area make patients hesitant about undergoing epicanthoplasty. These barriers are challenges to surgeons.

Methods: From January 2007 to May 2010, epicanthoplasty was performed for 23 patients using two-Z-plasty in a three-dimensional surgery model. A total of 20 patients underwent a simultaneous double-eyelid operation when required. The medial canthal distance was measured preoperatively and 12 months postoperatively. The extent of postoperative scarring and improvement of the epicanthal fold were evaluated after surgery.

Results: The average intercanthal length decreased significantly from a mean of 37.0±2.1 mm preoperatively to 31.4±1.9 mm 12 months postoperatively (p<0.01, paired t test). Epicanthoplasty yielded excellent aesthetic results in terms of an open medial canthus without definite relapse, hypertrophic scarring, and injury of the lacrimal apparatus during the 12-month follow-up period.

Conclusions: Two-Z-epicanthoplasty can be reproduced easily in a three-dimensional surgery model. This procedure is very effective for correction of the epicanthal fold, resulting in a pleasant-appearing, inconspicuous scar and a long-lasting outcome.
