The epicanthal fold is present during early infancy in all ethnic groups. However in most ethnic groups as the face grows this fold becomes less apparent. In adulthood, the epicanthal fold is a unique feature to the Asian eye.

The epicanthal fold is located on the middle portion of the Asian eyelid and is essentially redundant skin overlying the lacrimal lake (aka the pink portion of the central eyelid).

The shape of the epicanthal fold can vary considerably, with a prominent fold creating a smaller appearance to the eye.

An epicanthoplasty is a surgical procedure performed to change the shape of the epicanthal fold. This procedure is usually performed in conjunction with Asian double eyelid surgery.

Several various surgical techniques have been developed over the years, using various skin flap advancement techniques.

Like all techniques in plastic surgery, the best results are usually from careful preoperative evaluation and proper selection of an effective surgical technique.
