The Malar-Genial-Gonial Triangle: How I Think About the Central Face in Every Facelift
March 03, 2026 | Facelift
I want to start with something that might seem obvious but tends to get lost in how we talk about facelift surgery: the word “facelift” is actually a misnomer. The change patients are after isn’t a lift — it’s a younger appearance. And youth in the face, more than anything else, is a question of shape.
What I do is more accurately described as restorative facial shape surgery. There are infinite features to consider in that context, and over time I’ve zeroed in on a handful of keystone areas that I find consistently meaningful. One of them is the malar-genial-gonial triangle — what I call the MGG triangle.
This is how I think about it, why it matters, and what I actually do about it surgically.
What the MGG Triangle Actually Is
The triangle is defined by three points on the face: the most prominent part of the cheek mound — the malar eminence — the chin, and the angle of the jaw, which is the gonial angle. Connect those three points and you get a triangle that sits right in the central face, covering a lot of the real estate that determines how youthful and defined someone looks.
Moving clockwise, I think about the three lines that connect those points: the malar-genial line running from cheek to chin, the genial-gonial line from chin to jaw angle, and the gonial-malar line completing the triangle back up to the cheek.
My job — as I think about it — is to maximize the triangular character of that triangle. The more inverted and well-defined it is, the younger and more feminine the face looks.
What a Good Triangle Looks Like
In an attractive female face, this triangle tends to approximate either an equilateral or isosceles triangle — with the gonial-malar line being the shorter limb. That shorter upper line is what gives a face its lifted, defined quality. When that line lengthens with age, everything starts to look heavier and less structured.

“The shorter the gonial-malar line, the tighter the triangle — and the more youthful and defined the result. That’s the geometric goal behind everything I do in this region.”

Malar eminence, chin, and gonial angle — each one can be addressed independently, and each one matters.
The three sides of the triangle. What disrupts them, what defines them, and how to restore them.
The central cheek itself — often an area where selective hollowing can produce a very defining result.
Enhancing Each Defining Point
The three apices of the triangle can each be addressed on their own terms, and combining all three gives you a result that’s coherent rather than piecemeal.

The primary maneuver here is the mid-SMAS vertical oblique plication suture — essentially pushing volume upward onto the cheek mound. That’s the foundation. From there, fat grafting can augment the result as needed. I prefer to do this at the end of the case, once I can actually see where I am and assess the final position.
Fat graft: 3–5 cc · Deep or pre-periosteal plane · End of case
The chin is the inferior apex of the triangle, and its projection matters more than people often realize. For larger corrections I’ll use an osteotomy genioplasty — nothing gives you the same three-dimensional control. For moderate needs a chin implant works well. When the correction needed is minimal, fat grafting alone is often enough.
Fat graft: 2–3 cc anterior chin · 1–2 cc lateral chin / pre-jowl
The gonial angle defines the posterior apex and the width of the triangle. I use a retroauricular vertical SMAS suspension with a tethering bite and a small myotomy to allow the tissue to move and define properly. A SMAS turnover flap can add posterior augmentation where needed. When the gonial angle is well-defined, the gonial-malar line shortens — and the whole triangle tightens up.
Fat graft: 2–4 cc · SMAS turnover flap as indicated

What Disrupts Each Line — and What I Do About It
Two of the three lines have a primary disruptor. The third is different — it doesn’t get disrupted so much as it gets defined, or fails to be.

Disruptor
The main culprits here are the nasolabial fold and nasolabial crease — sitting inferior and medial to the malar eminence, right where this line wants to run clean. As the malar fat pad descends with age, the fold deepens and that smooth diagonal sweep from cheek to chin gets broken.
What I do: Three steps. First, micro-liposuction along the fold with a 2 mm cannula. Second, direct subcision — through a lip lift incision or trans-nasally — to release the tethering that’s holding that fold down even as the deeper tissue lifts. Third, fat grafting of about 1 to 1.5 cc to restore smooth contour over the top.
Disruptor
Here the disruptor is the jowl — no surprise. It forms as the malar fat pad descends and the mandibular ligament tethers tissue down, creating that convex bulge below the jaw border that breaks an otherwise clean line from chin to jaw angle.
What I do: The primary driver of jowl improvement is malar fat pad elevation. Re-suspending that fat pad directly unweights the jowl and restores the line. I’ll add micro-liposuction of the jowl as an adjunct to minimize recurrence — but jowl liposuction alone, without re-suspension, is treating the effect and not the cause.
Aesthetic Definer
This one is different. There isn’t really a disruptive feature along this line — what matters here is whether the line is defined at all. In thinner, younger faces you’ll often see a subtle hollow just inferior and posterior to the malar eminence. That hollow — what I call the infero-retro-submalar hollow — is what marks this line and gives the cheek its sculptural quality. Fuller faces don’t have it. And with age, as the malar fat pad descends, this line actually lengthens — which is one of the more underappreciated contributors to facial aging.
What I do: In appropriate patients, I place an oblique-vector SMAS suture secondary to the primary SMAS suture. The oblique vector creates focused tension that produces that infero-retro-submalar hollow. It’s not something I do in every case — it requires the right tissue thickness and the right patient — but when it’s indicated, it tends to contribute meaningfully to the overall result.

The Infero-Retro-Submalar Hollow
I want to say a bit more about this hollow, because it’s one of those things that separates a result that looks genuinely sculpted from one that just looks lifted.
The hollow sits inferior and posterior to the malar eminence. It’s not a void — it’s a subtle shadow that exists in youthful, lean faces and disappears as tissue descends and fills in with age. When you create it surgically, it does two things at once: it sharpens the definition of the cheek above it, and it marks the upper boundary of the gonial-malar line.
“`
“Volume gets a lot of attention in facelift surgery. But hollows matter just as much. The infero-retro-submalar hollow is what makes a result look three-dimensional rather than filled.”

What Lives Inside the Triangle
The central region of the triangle — the sub-malar cheek — is the third level of focus, and it’s counterintuitive for a lot of patients. When that area is full, it makes people look heavier than they are. It creates disproportionate volume in the lower half of the face. It’s actually aging in effect, even though volume is often thought of as youthful.
A true sub-malar hollow — what some call a buccal hollow or model hollow — is often one of the most attractive features of a young female face. When you create it, you’re not just removing something; you’re simultaneously enhancing the cheek above it, the jaw body below it, and the gonial angle behind it. It does a lot of work at once.
The technique is selective buccal fat pad reduction — either through direct resection or intraorally, depending on the situation. It’s not for everyone, and patient selection matters a lot here. But when it’s indicated, it can contribute substantially to the overall definition of the result.
Putting It Together
The MGG triangle is a way of organizing my thinking about the central face in facelift surgery. It gives me a framework to have a real conversation with a patient about what’s aging them, what’s achievable, and what I’m actually going to do about it — point by point, line by line.
More than that, it keeps me from treating any one feature in isolation. The malar eminence, the chin, the jaw angle, the lines between them, the central cheek — they all influence each other. When you address them as a system, the result is coherent. When you don’t, it shows.
That’s what restorative facial shape surgery means to me — not lifting, but restoring the geometry that helps a face look like a more youthful version of itself.
