Autologous Rib Nose Surgery — What Is Different with a Custom Implant (RIBFIT™)?

2025. 5. 30.

RIBFIT™ — an autologous tissue custom implant made by processing autologous rib cartilage into fine particles and compression-molding them in a 3D mold built from the patient's CT. How it differs from conventional rib rhinoplasty that carves cartilage, and what can be expected.

Key points

The autologous tissue custom implant RIBFIT™ is a method that processes autologous rib cartilage into fine particles, places them in a 3D mold made from the patient's CT data, and compression-molds them into an implant.
The fabrication process differs from carving a solid piece of cartilage, but whether warping, absorption, symmetry, and shape retention are actually superior must be verified through comparison data.
It is an option for those who feel aversion toward artificial implants like silicone or Gore-Tex.

"I knew implants were made of silicone, but I heard they can also be made from autologous rib."

A question from someone who had been looking into autologous rib nose surgery. While searching, they came across something called an 'autologous tissue custom implant' and wondered whether one made of autologous tissue might be better in terms of rhinoplasty side effects.

This article organizes how the autologous tissue custom implant RIBFIT™ differs from conventional autologous rib nose surgery, and what can be expected.

How is the autologous tissue custom implant RIBFIT™ made?

RIBFIT™ differs in its fabrication process from carving a solid piece of cartilage.

Autologous rib cartilage is processed into fine particles.
A 3D mold is made based on the patient's custom CT data.
Cartilage particles are placed in the mold and compression-molded to fabricate the implant.

The core difference is that instead of carving a block of cartilage into shape as in conventional autologous rib nose surgery, the form is set by compressing autologous rib particles inside a mold.

What changes when it is molded rather than carved?

Separating the items planned in mold fabrication from the results that require separate verification:

Item	What to check
Warping / absorption	Long-term change after compression molding, and data compared to solid cartilage
Left-right symmetry	The difference between mold design and actual surgical/recovery outcomes
Line / height	CT-based plans referenced, while reflecting real conditions like skin and scar tissue
Take / stability	Not assuming superiority from the fact of being autologous alone — check complications and revision rates

In summary, RIBFIT™ is a fabrication method combining a custom mold referencing CT with compression molding of autologous rib cartilage. Whether the result is superior to other materials and processing methods requires separate comparison data. The RIBFIT™ mold system and surgical process can be seen in more detail in the autologous rib RIBFIT™ guide.

Who can consider it?

It is an option for those who feel aversion toward artificial implants like silicone or Gore-Tex. If you, like the person who asked, were looking into autologous rib nose surgery and are weighing material choices, it helps to compare the characteristics of artificial implants and autologous tissue. The traits of each material are organized in the nose surgery materials guide.

At KOWON, we have introduced the RIBFIT™ system and perform the whole process in-house — from CT analysis to implant fabrication, surgery, and aftercare. However, which material and method fits differs by the nose's condition, so it is good to concretely set the surgical direction through an in-person diagnosis and CT scan.

Summary — "carved or molded" is the starting point

The autologous tissue custom implant RIBFIT™ processes autologous rib cartilage into particles and compression-molds them in a CT-based 3D mold — a fabrication process different from carving solid cartilage. Whether the process difference leads to actual differences in warping, absorption, symmetry, shape retention, and revision rates must be verified through comparison data. If choosing a material is a concern, the direction fitting your current nose condition can be checked in a 1:1 video consultation.

Frequently asked questions

Answers to common questions patients ask before a consultation.

How does RIBFIT™ differ from conventional autologous rib nose surgery?

Conventional autologous rib nose surgery carves the harvested rib cartilage into shape. RIBFIT™ processes rib cartilage into fine particles, then places them in a 3D mold made from the patient's CT data and compression-molds them into an implant. The difference is setting the form with a mold instead of a carving process.

What are the advantages of an autologous tissue custom implant?

There is the process characteristic of planning the form with a CT-based mold and compression-molding autologous rib cartilage into fine particles. Results for warping, absorption, symmetry, shape retention, and take must be checked together with comparison data and individual conditions.

If I dislike artificial implants, should I just choose RIBFIT™?

It is true that it is a method those with aversion to artificial implants like silicone or Gore-Tex can consider. However, which material fits differs by the nose's condition and the degree of support needed, so it is good to decide the surgical direction after diagnosis and a CT scan.

Responses to treatment and recovery progress vary by individual. Outcomes and side effects vary from person to person. Bleeding, infection, swelling and asymmetry may occur. Please consult our medical team before making a decision.
