The Value of Epicanthoplasty on the Modification of Upper-eyelid Appearance

The Value of Epicanthoplasty on the Modification of Upper-eyelid Appearance: a Retrospective Study

In East Asian populations, the combination of an epicanthic fold and mono-eyelid is one of their anatomical characteristics. Misalignment of the orbicularis oculi muscle and fibrous connections leads to longitudinal tension, forming the epicanthic fold. The epicanthic fold may diminish the aesthetic effects of eyelid cosmetic surgery, shorten the horizontal length, and affect the postoperative shape of double eyelids. As upper eyelid cosmetic surgery is one of the most common cosmetic procedures in Asia, there is increasing attention on the modification of the epicanthic fold and its impact on the formation of double eyelids.
