What is the difference between epicanthoplasty and blepharoplasty?

Blepharoplasty is related to surgery of the eyelid and could be a traditional "freshening up" of a middle aged man/woman for brighter look and improve vision if there's too much skin. Epicanthoplasty is almost exclusively done in Asian population to "open up" either the front/near your nose or the back/closer to your ears. It can change the look of a person somewhat and is almost always optional.
Wish you the best in your journey.

Treatment of the epicanthal fold is an individual issue.  Upper blepharoplasty with and without epicanthoplasty will typically result in an improved appearance with more of the eyelid above the lashes visible.  There is a prefered technique for epicanthoplasty which does not leave visible scars in this area. Cheers.  Please consult in person with an experienced Board Certified Plastic Surgeon prior to making treatment decisions. Cheers.

Blepharoplasty - surgery of eyelidAsian blepharoplasty - double eyelid surgeryEpicanthoplasty - surgery of epicanthal( mongolian) fold to enlarge the opening of the inner corner of the eyeSince medial epicanthal fold is not an anomaly, not all medial epicanthal folds need to corrected. In fact, many consider it an asian beauty and find it aesthetically pleasing. Before considering this procedure, you should have a good idea how you would look with or without this procedure. Your surgeon should be able to show you this with a mirror. It really comes down to your personal preference.

it really depends on your anatomy.  There are not that many ideal candidate for epicanthoplasty so approach that one cautiously.  Typically Asian eyelid surgery or Asian blepharoplasty performed properly without epicanthoplasty is more than enough to create a very nice natural look with either a crease that is a bit higher allowing for easier makeup use or even a lower crease that is still enough to brighten the eyes.  It is also important to remember that the epicanthoplasty, which is performed at the inner corner of the eye, is the most likely place for you to develop visible scarring after your eyelid procedure.  I'll attach a video that may be helpful to you.Chase Lay, MD
