For patients considering facial contouring surgery, one of the most common questions is:
“How much smaller can my face actually become?”
Many people focus on the number of millimeters that can be reduced. However, in facial contouring surgery, the more important question is not how much bone can be removed, but which areas should be reduced and how they should be balanced.
Two patients may both have 1 cm of reduction, yet one appears dramatically smaller and more harmonious, while the other may look less natural despite a larger reduction.
In this article, I’ll explain how facial contouring surgery actually makes the face smaller, using the cheekbones and jawline as examples.
Understanding the Three Parts of the Cheekbone
Although the cheekbone appears to be a single structure, aesthetically it is helpful to divide it into three separate areas:
- Anterior zygoma (front cheekbone)
- Malar eminence (45-degree cheekbone)
- Lateral zygomatic arch (side cheekbone)
Each area affects facial appearance differently.
1. Anterior Zygoma
A moderate amount of volume in the anterior cheekbone creates a youthful and vibrant appearance.
Excessive reduction of this area can make the face appear flat and less three-dimensional. Therefore, in most cases, the anterior cheekbone is preserved as much as possible, and in some patients, subtle augmentation may even be considered.
2. Malar Eminence (45-Degree Cheekbone)
This is the most prominent part of the cheekbone when viewed from a 45-degree angle.
When excessively projected, it can create a stronger or more masculine appearance and often disrupt the smooth contour of the facial profile.
3. Lateral Zygomatic Arch
This area is one of the most important determinants of facial width when viewed from the front.
Many patients who feel their face looks wide are actually noticing prominence in this region.
Making the Face Smaller Is Not Just About Reducing the Side Cheekbone
In the past, many zygoma reduction procedures focused primarily on moving the lateral arch inward.
While this could narrow the face to some degree from the front view, the malar eminence (45-degree cheekbone) often remained unchanged. As a result, the malar prominence could appear even more noticeable after surgery.
In fact, this is one of the most common reasons patients seek revision cheekbone surgery.
For this reason, modern facial contouring surgery typically addresses both the malar eminence and the lateral zygomatic arch together to achieve a more balanced and natural facial shape.
Does Greater Reduction of the Malar Eminence (45-Degree Cheekbone) Cause More Sagging?
One reason some surgeons hesitate to aggressively reduce the malar eminence is concern about soft tissue sagging.
However, modern techniques focus not only on bone reduction but also on:
- Minimizing soft tissue dissection
- Repositioning soft tissue appropriately
- Selective fat reduction when necessary
- Rigid fixation of the repositioned cheekbone segments
When performed properly, these measures can significantly reduce the risk of postoperative sagging.
Therefore, preserving excessive malar prominence solely out of fear of sagging is not always the best solution.
How Much Reduction Is Actually Possible?
The amount of reduction depends on each patient’s anatomy.
For the lateral zygomatic arch, inward movement of approximately 0–7 mm per side is generally possible.
This means that total facial width reduction can exceed 1 cm in some patients.
However, greater reduction is not always better.
Patients with a relatively large skull or prominent mandibular angles may actually develop less balanced facial proportions if the cheekbones are reduced excessively.
Ultimately, successful facial contouring is about achieving harmony rather than maximizing reduction.
The Same Principle Applies to the Jawline
Historically, mandibular contouring often focused on removing as much of the gonial angle as possible.
Although this could create a dramatic change from the front view, it frequently resulted in an artificial-looking jawline from the side profile.
Today, most surgeons prefer to preserve a natural mandibular angle while reshaping it more conservatively.
The goal is not to create an obviously operated appearance, but rather to make it look as though the patient naturally has a smaller face.
Why Cortical Bone Reduction Matters
One of the most important concepts in modern jaw contouring surgery is cortical bone reduction.
After refining the mandibular angle, the outer cortical layer of the jawbone can be additionally reduced.
Because the cortical bone contributes significantly to facial width, removing approximately 5 mm per side may provide more than 1 cm of additional width reduction when both sides are combined, on top of the effect achieved by angle reduction alone.
By combining conservative mandibular angle reduction with cortical bone reduction, surgeons can create a noticeably slimmer facial appearance without eliminating the natural contour of the jawline.
The Goal Is Not the Smallest Face—It’s the Most Natural One
The purpose of facial contouring surgery is not simply to remove as much bone as possible.
A successful result requires:
- Preserving appropriate anterior cheekbone volume
- Balancing the malar eminence (45-degree cheekbone) and lateral arch
- Maintaining a natural jaw angle
- Reducing facial width while preserving harmony
In the end, the best facial contouring surgery is not the surgery that removes the most bone.
It is the surgery that creates the most natural and balanced facial appearance.
