Hello. We are Re:본 Plastic Surgery, meeting you at Exit 1 of Sinsa Station.
During consultations, we often meet people who say things like, “I heard that if you do an inner corner procedure when getting double eyelid surgery, the eyes look much bigger...,” or “My eyes look narrow, so I want to get double eyelid surgery and inner corner surgery together~”
That is because most people see eye corner surgery as an additional procedure done alongside double eyelid surgery.
The term commonly used in Korean, “앞트임,” is a nickname created to make it easier for people to understand. Its original academic names are “medial canthoplasty” or “epicanthoplasty.”
The fact that it has an academic name means, in essence, that an independent surgical method is used to solve an existing problem.
Rather than being a mere option in eye surgery, it should only be performed when correction is actually needed in order to achieve stable results and to prevent various side effects caused by inner corner surgery in advance.
At our clinic as well, many patients visit for revision surgery because their previous inner corner surgery was done too aggressively. Once tissue that has already been opened is corrected back to its original state, it is that much more difficult.
To prevent such unfortunate cases, today we would like to take a more detailed look at ‘eye corner surgery.’

The ‘epicanthic fold’ commonly found in East Asians
Earlier, we said that the medical term for inner corner surgery is ‘epicanthoplasty.’
To understand the surgery, we first need to know about the ‘epicanthic fold.’
The epicanthus, or epicanthal fold, is a fold in which the upper eyelid extends past the inner corner of the eye and down to below the medial canthus, covering the inner side of the eye.
It is a feature often seen in East Asians, where the natural double eyelid rate is only around 30%. Because it covers the inner corner of the eye like a hook, it can easily make the eyes look constricted or give a sharp impression.
However, even if the epicanthic fold is prominent, opening this area does not automatically make the eyes larger and more defined.
At the inner corner of the eye is the ‘lacrimal lake’ (the red area), and the amount of exposure varies from person to person.
Even if the epicanthic fold is prominent, if double eyelid surgery can control the degree of lacrimal lake exposure, an inner corner procedure is not necessarily needed.
Rather, if inner corner surgery is performed together with double eyelid surgery in such cases, the lacrimal lake may become excessively exposed, which can lead to unnatural results. This is something you should keep in mind.
Therefore, when considering inner corner surgery, the decision should be made by comprehensively considering the degree of epicanthic fold development, the degree of lacrimal lake exposure, and the range of lacrimal lake that would become visible if double eyelid surgery is performed.

How is inner corner surgery performed?
Inner corner surgery should not be approached as simply opening the inner corner of the eye; it should be understood as improving the epicanthic fold.
Only then can the various side effects mentioned earlier be prevented in advance.
If inner corner surgery is deemed necessary, the epicanthic fold should be opened to an appropriate degree from an anatomical perspective, and the structure should be corrected so that a stable shape can be restored when a double eyelid is created.
When people undergo eye corner surgery, most assume, “Maybe they just make a small cut in the epicanthic fold?”
~
A heavily developed epicanthic fold also means that the internal structures are intricately intertwined, so the surgery must be performed while taking into account various factors such as the orbicularis oculi muscle of the upper eyelid and multiple fibrous tissues.
If you simply open the area without understanding the epicanthic fold, you can never create harmonious eyes, so please be especially careful about this.

Who is inner corner surgery suitable for?
Even if the lacrimal lake is positioned appropriately on the inner side and the epicanthic fold needs improvement, we do not recommend inner corner surgery if the distance between the eyes is excessively narrow.
In such cases, performing inner corner surgery can make the distance between the eyes appear even narrower and may create a harsher impression.
Therefore, inner corner surgery is recommended for people who have sufficient distance between the eyes, people whose impression still looks constricted even after double eyelid surgery, and people who want to correct the position of the front line of the double eyelid.
Inner corner surgery is more difficult than you might think, isn’t it?
Even a very small opening of 1–2 mm can greatly change the impression, so it must be approached carefully.
It is not something to treat lightly just because you simply want larger eyes, so it may be best to make your decision only after having a thorough consultation about it.
At Re:본 Plastic Surgery, the director provides one-on-one consultations and recommends surgery only when it is truly necessary.
Inner corner surgery can bring a major change in the before-and-after impression. Carefully examine whether it is the right procedure for you before deciding.
We will be back with a more informative post. Thank you. ^^
