If your mouth looks a little “too forward”,
it can get frustrating fast.
Is ASO enough
or do I need double jaw surgery?
That’s usually the most confusing part.
Let’s make it clear and simple.
This is what the change can look like.
Diana
Every one thinks I got a nose job, but I did not. I believe the jaw surgery lifted my midface.
When he tells you that you mouth won’t remain twisted, it is the truth.
Diana started because of her “protruding mouth” concern,
but the biggest change she noticed was
overall facial balance
—especially how her midface looked.
Hanna
I had a weak chin, a protruding mouth, and facial asymmetry. Therefore, I underwent genioplasty, double jaw surgery, and V-line surgery.
For Hanna, it wasn’t just “pushing the mouth back.”
Her results were about balance: chin, jawline, smile, and symmetry.
Selina
During my vacation, one of my friends recommended Dr. Lee to me... So, I decided to fly to Korea to meet Dr. Lee as well.
With bigger surgeries,
what you need most is clarity.
Not vague promises
just a plan you truly understand.
Now here’s the part that matters most.
Don’t start with “Which surgery?”
Start with why your mouth looks protrusive in the first place—
and then decide whether ASO is enough or double jaw is needed.
Dr. Lee Joong Kyu usually starts with jaw balance, not just the lips.
That’s why 3D simulation becomes a big part of the explanation.
A protruding mouth concern is common. Orthodontics can help in some cases, but today I’m focusing on surgical options—by “type.” In consultation, I look at three things first: 1) Is it mainly the front segment (teeth/gum bone) that is forward? 2) Is the lower jaw set back, making the mouth look more prominent? 3) Is it a broader facial balance issue (facial length, asymmetry, contour)? That’s what separates cases where ASO is enough from cases where Double Jaw Surgery is more appropriate.

ASO (Anterior Segmental Osteotomy) is a surgery that typically creates space
(often by removing teeth behind the canines),
then moves the front gum-and-tooth segment backward to reduce protrusion.
It tends to fit better when facial length and asymmetry are not major issues.
If the main issue is “just the front” and the face is relatively shorter with minimal asymmetry, ASO can be effective. But if the face is long or asymmetry is significant, moving only the front segment backward may disrupt balance—so double jaw surgery should be considered first.

Double Jaw Surgery repositions the upper and lower jaws to improve overall balance—
including front-back projection, facial length, and asymmetry (depending on the case).
Sometimes patients feel “my mouth is protruding,” but the main reason is the lower jaw is set back—so the mouth looks more forward in comparison. In those cases, focusing only on “pushing the mouth back” can make the face look longer or heavier. The goal is to reposition the jaws to restore balance first.

In some cases, it’s not only about the mouth position—
it’s also about jawline shape, facial width, and asymmetry.
The typical logic is: fix the foundation (jaw balance) first, then refine if needed.
Even when protrusion is not extremely severe, a long face, asymmetry, or strong jawline concerns can change the plan. ASO alone may not address overall balance. Double jaw surgery allows broader adjustment (including vertical and asymmetry correction in some cases), and contouring can be added only when appropriate.

Genioplasty moves or reshapes the chin to improve the profile line.
It doesn’t “move the mouth back,” but it can make the mouth look less prominent by restoring balance.
If pushing the mouth back feels too invasive for you, chin advancement can be a smaller option to improve harmony. But if the core issue is facial length, asymmetry, or jaw position, ASO or double jaw surgery may be the more appropriate direction.

The most practical question isn’t “Is it hard?”
It’s when breathing feels easier, when talking feels normal, and when food feels manageable.
The first day was the hardest.
By the third day, my breathing improved a lot.
Now, two weeks post-op, I can eat soft foods and talk much better.
I experienced coughing with a lot of saliva and blood for almost two weeks.
would like to share you guys about my 3 months post surgery. I think it still swollen in my jowl but it so much better than before.
I look so transformed for the better.
After 6 months, people often talk less about “big change” and more about
things settling into a more natural look.
Now, more than two years have passed, and it has been a beautiful journey when I look back at the progress.
So far, I am satisfied with the results, and I would like to recommend Dr. Lee from The Face Dental.
Long-term, what stands out is often simple:
“I’m happy I did it.”
That’s the part you can’t fake
because it only shows up after time passes.
The difference isn’t only the surgery name.
It’s understanding your plan—clearly—before you commit.
He answered my questions in detail, and we communicated really well.
He was right about every thing.
