Why the Lateral Philtrum and Mouth Corners Must Be Evaluated Together | Golden Diamant Plastic Surgery

Hello.

I am Dr. Sang-hoon Song, Chief Director of Golden Diamant Plastic Surgery in Gangnam.

During consultations for philtrum reduction or corner mouth lifts, I often hear very similar concerns.

“My philtrum feels long, but the sides look even longer than the center.”

“The corners of my mouth droop, but I'm worried lifting just the corners will make it look too obvious that I had surgery.”

“My lips look narrow and stiff, but I can't pinpoint what the exact problem is.”

The perioral area may appear small, but in reality, multiple anatomical structures are interconnected.

The central philtrum from the columella to the upper lip, the lateral philtrum extending from beneath the alar base toward the corners of the mouth,

and the position and angle of the mouth corners all come together to create a single overall impression.

A "long philtrum" can manifest in several different ways.

Some individuals have a long central philtrum,

while others have a lateral philtrum that appears longer than the center.

For some, rather than the length of the philtrum itself, the outer edge of the upper lip sags downward, making the mouth area look significantly more droopy.

In particular, when the lateral philtrum is long and the mouth corners point downward, it can give a gloomy, tired impression that looks even more pronounced than the actual physical downturn of the corners.

In such cases, shortening only the central philtrum may result in an underwhelming improvement.

This happens because while the center has shortened, the outer blank space and the downward direction of the mouth corners remain unchanged.

Conversely, lifting only the corners of the mouth can also leave something to be desired.

If the lateral philtrum is long and the outer upper lip droops downward, lifting only the corner tips

can cause the contour of the lips to appear interrupted mid-line, or make the corners look unnaturally pulled up on their own.

Therefore, in modern perioral consultations, rather than making dramatic changes to just a single area, it is crucial to first analyze which lines are prolonged and which lines appear sunken or drooping.

This is where lateral philtrum reduction holds significant value.

Instead of addressing the central philtrum, it adjusts the vertical length between the alar base and the outer upper lip,

helping to refine and tidy up the outer contour of the upper lip.

In essence, its role is to reduce the vertical empty space along the lateral aspect of the mouth.

However, the lateral philtrum directly meets the mouth corner at its end.

Therefore, one must also evaluate whether the newly refined upper lip contour achieved by shortening the lateral philtrum

connects seamlessly and naturally with the existing mouth corners.

Ultimately, the key is not “how much to change,” but “how to connect the lines.”

The perioral region is not composed of isolated components—the central philtrum, lateral philtrum, upper lip vermilion border, and mouth corners—

but rather functions as a single unified aesthetic flow.

In the next post, I will explain the role of our frequently requested Golden View Corner Mouth Lift when paired with lateral philtrum reduction,

and why a harmonious transition between the two procedures is so essential.

Preview of Part 2

- Is a Golden View Corner Mouth Lift simply about elevating the corners?

- Why does evaluating lateral philtrum reduction and a corner mouth lift together yield more natural results?

- Does everyone need both procedures combined?

I will continue this discussion in Part 2.

Thank you.

Frequently Asked Questions

What is lateral philtrum reduction?

It is a surgical procedure that adjusts the vertical height between the bottom of the alar base and the outer upper lip. Rather than focusing on the central philtrum, it reduces the vertical empty space on the outer sides of the mouth area to help refine and balance the outer upper lip contour.

Why might reducing only the central philtrum feel insufficient?

Because the lateral empty space and downward angle of the mouth corners remain intact. When someone has a long lateral philtrum combined with drooping mouth corners, addressing only the center can make the overall aesthetic improvement feel subtle or incomplete.

What happens if only the mouth corners are lifted when the lateral philtrum is long?

The continuous contour of the lips can look broken or stepped, making the mouth corners appear unnaturally hoisted on their own. Raising only the endpoints while the outer upper lip continues to sag downward risks creating an awkward, unnatural line.

Why must the mouth corners and lateral philtrum be evaluated together?

Because the lower edge of the lateral philtrum connects directly into the corner of the mouth. When reducing the lateral philtrum, the surgeon must verify that the newly established upper lip line transitions smoothly and harmoniously into the position and angle of the mouth corners.
