A Defined Waist Is Not Created by Fat Reduction Alone2026.04.14
— Rib Remodeling: Redefining the Structure of the Waist —
In recent years, a new approach to body contouring has gained popularity in the US and Europe:
Rib Remodeling × Waist Liposuction × Fat Grafting Breast Augmentation
This combined strategy allows for the creation of a structurally refined waistline that cannot be achieved through liposuction alone.
Why Liposuction Alone Has Limitations
The shape of the waist is not determined solely by fat volume.
Key factors include:
- Rib cage angle
- Skeletal width
- Position of the waist indentation
While liposuction can reduce volume, it does not change the underlying bone structure.
As a result:
- The waist position may remain unchanged
- The contour may appear less defined
- The ideal S-curve may not be achieved
What Is Rib Remodeling?
Rib remodeling is a procedure that modifies the angle of the lower ribs to redesign the waistline.
This allows for:
- A deeper inward curve of the waist
- Optimization of the waist position
- Improved overall upper body silhouette

Case Study: 1 Week Post-Op
This patient underwent:
- Waist liposuction (approx. 2200cc of pure fat removal)
- Rib remodeling
- Fat grafting breast augmentation
The patient had previously undergone abdominal and flank liposuction overseas and already had a defined waist.
By adjusting the rib angle, we were able to
reposition the waist to its most aesthetically optimal location.
Although swelling is still significant at 1 week post-op,
changes in both the position and angle of the waistline are already visible.
True Waist Design Is About Position
A common misconception is that having a waist is enough.
In reality, what matters most is
where the waist is positioned.
Rib remodeling enables us to:
- Relocate the waist to the most visually flattering point
- Enhance overall body proportions
The AVAN TOKYO Structural Approach
At AVAN TOKYO, we focus not only on fat, but also on skeletal structure, including:
- Ribs
- Clavicle
- Scapula
By adjusting structural projection when necessary, we achieve:
- A more refined silhouette
- Enhanced appearance in fitted clothing and dresses
- Improved three-dimensional contour

Ideal Candidates
- Patients dissatisfied after liposuction
- Those who want to change the position of their waist
- Patients seeking a more defined S-line
- Individuals aiming for a Western-style body contour
Total Body Design
At AVAN TOKYO, we combine:
Fat reduction × Structural adjustment × Fat redistribution
to achieve results beyond conventional procedures.
Beauty Is Defined by Structure
Body contour is determined not only by fat, but by:
Structure × Volume × Placement
