The Art of the Midface: A Story of Structure, Sequence, and Subtlety
Let me share with you a profound truth about facial aesthetics: the midface is not one simple territory, but two distinct lands divided by an invisible line. This line connects three key points and, like a border between countries, it separates the lateral midface from the medial midface. Understanding this division is the foundation of our entire journey today.
On the lateral side, we find passive tissues. As the years pass, gravity gently pulls them downward, creating that soft laxity along the jawline. But on the medial side, something entirely different happens. Here, structures like the zygomaticus major and the levator anguli oris muscle pierce through the layers from bone to skin. Rather than sagging, this region experiences a quiet disappearance of volume. This is the first great secret: sagging is not the same as volume loss.
And here lies a critical principle that many overlook. If we add volume to the lateral side first, we will need less volume medially. It is a profound mistake to rush into filling the medial cheek before building a strong lateral foundation. Think of it as constructing a house: you must set the scaffolding before you hang the curtains.
The Architecture of the Cheek
This part of the face is not simply a flat canvas. The lateral midface is organized like layers of an onion—concentric rings where we can reposition tissues. But the medial cheek is different. It is more like roof tiles, stacked one upon another, with structures transecting the layers. This gives the medial region far more stability.
My treatment plan begins with the lateral midface. First, I must identify the boundaries of the zygomatic arch. I follow the cheekbone with my fingers, tracing its natural direction. Once I am confident I have found it, I understand the angle of the cheekbone, and that is essential information. Next, I need to pinpoint the apex of the cheek—the most projected part. This is not an anatomical structure but an aesthetic one. A reliable way to find it is to locate the midpoint between the orbital bone laterally and a vertical line we have already established. That is where we want to create projection.
In our subject, she already possesses beautiful, natural cheekbones. There is some volume loss medial to them, which means her apex is already well-projected. However, this does not mean we should add nothing. We will deliberately add structure here to avoid overfilling medially later. This is a strategic choice, not a random one.
The Three Targets of the Lateral Midface
The first target is the apex of the cheek, which lies in the suborbicularis oculi fat (SOOF). The second target is the lateral zygomatic arch, deep into the preperiosteal fat along the zygomatic bone. The third target is the area behind the line of ligaments beneath the zygomatic bone—the preauricular, subzygomatic, and submandibular region. This entire region can be volumized with hyaluronic acid in layer two. This is what gives the lovely definition and tension laterally to that ligament line, improving both the jawline and the midface.
For this treatment, we use a 22-gauge cannula. After a small scratch for the entry point, we glide through the dermis. Layers matter here. We move beneath the orbicularis oculi muscle, feeling a tethering and dimpling as we enter the SOOF. But there is a deeper plane still. Beyond the SOOF is another fascial plane, and then the preperiosteal fat. That is where I inject today, aiming for maximum structural depth. I glide down onto bone, then deposit approximately 0.3 ml of hyaluronic acid at the apex of the cheek. Then, I reposition in the subcutaneous plane along the zygomatic arch, again perforating through the orbicularis oculi to reach the deep plane. This creates a smooth, continuous transition from the lateral arch to the apex.
After this half-syringe is used, we must resist the temptation to flatten the gel. A deliberate shape has been created. Pressing with the thumb would spoil it. Instead, we can gently roll with a finger to create definition. The result is a nicely defined apex and lateral projection.
The Medial Midface: A Deeper Conversation
Now, we shift focus to the medial midface. First, I find the inferior bony margin of the orbit. This is the highest point of any treatment—above it lies the eye, and we must never trespass. I then locate the medial limbus of the iris while the patient looks straight ahead. This point corresponds to where the zygomatic cutaneous ligaments insert into the prominence of the zygoma. These two major ligaments define the structural shape of the midface.
We have already treated the SOOF between these ligaments. What remains? With aging, the fat pads in the subcutaneous plane descend with gravity and skin elastosis. This reveals a bony ledge called the palpebral groove, which sits over the lateral aspect of the undereye. This is not the tear trough. It is a specific groove revealed as tissues migrate downward. We can treat it, and the target is the interlaminar fat, which lives between the bands of the orbicularis retaining ligaments. This is an extension of a tear trough treatment.
The tear trough itself is the gap between the medial aspect of the orbicularis retaining ligament and the nasojugal groove. The nasojugal groove is the superior pole of the nasolabial fat pad. It is a very narrow target, but it can extend into the palpebral groove treatment. However, we must work from deep to superficial. There are deeper targets in the midface that we address before the tear trough.
The first deep target is the deep medial cheek fat. This is the intended target for many original filler treatments. But here is the caution: if the patient gives a big smile, there is little scope for excessive volume. If filler moves into the wrong zone, it will move on animation. Therefore, we must inject deep to the muscles. In the medial cheek, we have the infraorbital foramen, which emerges from the maxilla. The vessels from this foramen move medially, separating two compartments down onto bone. Medial to the vessels is the deep pyriform space. In this case, I do not feel significant recession of the maxilla, so I will not treat the deep pyriform space. Instead, I focus on the deep medial cheek fat, which sits beneath the levator labii superioris muscle.
To access this fat pad, we can use a cannula in the deepest plane beneath the SMAS and the levator, or use a needle down onto bone. I choose a needle. The major risks here are the facial artery becoming the angular artery along the nasolabial fold, and the deep infraorbital vessel. To minimize risk, I inject in line with the midpupillary line or lateral limbus of the iris, down onto bone, slowly, using a high G prime product. This ensures the gel settles beneath the lip elevator muscles, avoiding movement on expression.
I use a 27-gauge needle, inject 0.3 ml down onto the maxilla, aspirate for a full 10 seconds, and inject with slow pressure. The cohesiveness of the product keeps it in the deep plane. After gently molding, I address the deep lateral cheek fat as well, using another 0.2 ml. The levator anguli oris muscle divides these two compartments. With both deep compartments volumized, we see a significant improvement in the hollowing of the medial cheek.
The Final Reflection
When we ask the patient to smile, we see we have not overfilled. The result is natural, structural, and stable. This is the wisdom of the midface: start laterally, build deep, and respect the moving parts. The cheek is not a single volume to be restored, but a delicate interplay of layers, ligaments, and fat compartments. Treat it with sequence, and the result will speak for itself.
