How is the RIBFIT™ diced autologous rib implant made — CT-based custom mold and surgical steps
2025. 5. 10.
RIBFIT™ — finely dicing autologous rib cartilage and compression-molding it into a 3D CT-based custom mold. Organizes the 5 surgical steps, differences from existing dermis·diced-rib methods, and when it can be considered.
Key points
- RIBFIT™ harvests the patient's own rib cartilage, finely dices it, then compression-molds it into a personalized custom mold built from 3D CT data to create an autologous-tissue implant.
- A method that designs the target shape in advance with diced particles and a custom mold, while planning the bridge line without an artificial implant.
- It can be considered for those who experienced inflammation·foreign-body sensation after artificial implants, have thin skin, or need stability first after multiple revisions.
In rhinoplasty, choosing an implant is a complex medical decision that goes beyond simple aesthetics — the patient's biocompatibility, long-term stability, and infection risk must all be considered. Some people can't escape the worry of inflammation when an artificial implant has to be used, and the RIBFIT™ system started from that concern.
This article organizes what RIBFIT™ is, which steps it proceeds through, and how it differs from existing autologous-tissue rhinoplasty.
01
What is RIBFIT™?
RIBFIT™ is a system that harvests the patient's own rib cartilage, finely dices it, then compression-molds it into a personalized custom mold built from 3D CT data. This lets the bridge line be planned with an implant made of autologous tissue — no artificial implant needed.
It's less a simple autologous-tissue surgery than a hybrid rhinoplasty grafting digital technology onto tissue engineering. Guidance on the autologous rib cartilage approach overall can be seen at RIBFIT™ autologous rib cartilage.
02
Which steps does the surgery proceed through?
- CT imaging and anatomical analysis — precisely analyzes nasal structure, skin thickness, bone-cartilage junction positions and more.
- Custom 3D mold design·fabrication — simulates the ideal shape to be inserted at the bridge.
- Autologous rib harvest, then dicing — processes the harvested cartilage into fine particles that can be compressed into the mold.
- Particle compression molding — compresses into the designed mold to complete the autologous-tissue implant.
- Insertion and seating — realizes and fixes the bridge contour.

How does it differ from existing autologous-tissue rhinoplasty?
Even with the same autologous tissue, the way the shape is made differs.
| Item | Existing autologous dermis | Existing diced autologous rib | RIBFIT™ |
|---|---|---|---|
| Tissue form | Dermis cut and used | Used after particle-level processing | Particle-level processing, then compressed |
| Implant shape | Shaped by eye | Shaped by eye | CT-based 3D mold precision design |
| Absorption·shape change | Affected by individual variation and processing | Affected by individual variation and processing | Actual long-term comparison data on the compressed structure needed |
| Foreign-body sensation | Autologous tissue can still differ in feel·contour | Autologous tissue can still differ in feel·contour | Autologous tissue, but individual differences in feel·contour exist |
| Shape | Planned via cutting·layering | Planned via particle placement | Target shape designed in advance with custom mold |
| Recovery period | Differs by harvest extent | Differs by harvest·fascia use | Differs by harvest extent and surgical content |
RIBFIT™ is an option that designs the target shape with autologous tissue without an artificial implant. However, asserting that inflammation·absorption·revision rates are lower than other methods requires comparative data, so for now we only explain the differences in material and fabrication method. Rhinoplasty planned without artificial implants overall can be seen in more detail at implant-free rhinoplasty.
04
In which cases can it be considered?
- When inflammation or foreign-body sensation was experienced after past artificial implant use
- When thin skin makes silicone contours easily visible
- When aversion to implants is strong
- When stability must come first after multiple revisions
- When autologous rib cartilage surgery is wanted but warping·asymmetry is a concern
Having performed diverse rhinoplasties for over 20 years, what feels most important is 'design matched to the individual's anatomy' and 'stable tissue response.' RIBFIT™ is a method designed to target both elements together.
05
Summary — it's about how it's made, not the material
RIBFIT™'s verifiable difference is the fabrication method: finely dicing autologous rib cartilage and compression-molding it into a CT-based custom mold. Comparative claims of superior accuracy·stability·absorption over other autologous methods require separate evidence, so judgment should center on whether this fabrication method suits the current nasal state.
