Hello, this is AB Plastic Surgery.

I wrote this post to answer some of the questions many of you have been curious about.

Q. I’m curious about the difference between autologous costal cartilage and donor costal cartilage. Is it true that using donor rib cartilage greatly increases the chance of inflammation??

AB. No. The difference is not large.

Autologous costal cartilage is cartilage taken from your own body and used,

and donor costal cartilage is cartilage taken from another person, processed into a product so that there is no immune reaction, and then used.

Naturally, using your own tissue feels safer and more reassuring.

However, there is no need to be overly worried just because it is donor costal cartilage!

A meta-analysis is an integrated analysis of multiple previously published studies.

Because it is analyzed using a large sample size, it can be considered a more accurate result.

If we cite the paper titled "Is Irradiated Homologous Costal Cartilage Reliable? A Meta-Analysis of Complication Rates in Rhinoplasty," published in 2021,

Plast Surg (Oakv). 2022 Aug;30(3):212-221. doi: 10.1177/22925503211011973. Epub 2021 May 17. Nikita Kadakia et al.

It analyzed complications when donor rib cartilage was used in rhinoplasty, and the resorption rate was 1.14% and the inflammation rate was 1.2%, which are very low numbers.

In another paper published in 2020,

"Comparison of Autologous vs Homologous Costal Cartilage Grafts in Dorsal Augmentation Rhinoplasty: A Systematic Review and Meta-analysis," you can also see that,

JAMA Otolaryngol Head Neck Surg. 2020 Apr 1;146(4):347-354. Peter M Vila, et al.

the complication rates did not differ greatly between the use of autologous rib cartilage and donor rib cartilage.

In conclusion, if we compare only these two options, autologous rib cartilage may be a little stronger and better able to withstand inflammation,

but when also compared with other types of cartilage or artificial materials,

donor rib cartilage is a much better material for surgery because it is large and sturdy, and the chance of inflammation is also low.

If your situation calls for rib cartilage, you can use either autologous or donor cartilage,

and there is no need to choose another material out of vague fear.
