“Waistlines Are Not Defined by Fat Alone”2026.05.24
AVAN TOKYO’s philosophy behind RIBXCAR (Rib Remodeling Surgery)
One of the latest body contouring trends becoming increasingly popular in the US and South America is:
“RIBXCAR” (Rib Remodeling Surgery)
Particularly in:
- Miami
- Beverly Hills
- Colombia
- Brazil
high-end body contouring is evolving toward:

“Rib Remodeling + Waist Liposuction + Fat Transfer Breast Augmentation”
to redesign the entire upper body silhouette.
At AVAN TOKYO, we believe that:
“The position of the waist itself”
can be redesigned.
Waistlines are influenced by bone structure
Many people think:
“Removing fat creates a waistline.”
However, in reality,
skeletal anatomy plays a major role.
Factors such as:
- Rib flare
- Rib angle
- Pelvic width
- Distance between ribs and pelvis
- Waist height
all dramatically affect body proportions.
This means that:
liposuction alone has limitations.
What is RIBXCAR?
RIBXCAR is a procedure that reshapes the lower ribs (mainly ribs 10–12) to narrow the waistline from the skeletal level.
At AVAN TOKYO, we do not remove the ribs.

Instead:
controlled partial fractures
are created using specialized instruments, and the ribs are repositioned inward with long-term corset fixation.
In other words:
the skeletal frame itself is redesigned.
Ideal candidates
RIBXCAR may be suitable for patients who:
- Are already relatively slim
- Have limited improvement potential from liposuction alone
- Have strong rib flare
- Feel their waist appears “straight” despite being thin
- Desire a higher-level body contour
Procedure flow
The surgery is performed under:
general anesthesia
with anesthesiologist support.
Typical flow:
- Design and evaluation
- Waist liposuction
- Rib remodeling
- Corset fixation
- Fat transfer breast augmentation if needed
Risks and downtime
RIBXCAR is a relatively invasive body contouring procedure.
Possible risks include:
- Pneumothorax
- Pain
- Swelling
- Asymmetry
- Relapse
- Infection
- Chronic discomfort
Long-term corset fixation is extremely important to maintain the result.
AVAN TOKYO’s approach to body contouring
At AVAN TOKYO, we focus not only on fat removal, but also on:
bone structure, skin, muscle, and overall body balance.
By combining:
- Rib remodeling
- Waist liposuction
- Fat transfer breast augmentation
- Hybrid breast augmentation
we aim to create:
“a naturally elegant upper body silhouette.”
