What are the chances of cartilage resorption?

There is only a small amount of cartilage resorption
that can occur in patients. Typically only up to 20% of cartilage resorption,
if any, occurs by five year mark then stabilizes for long-term. However,
cartilage resorption very rarely takes place for patients who have had surgery. 

Hi and thanks for your question. Although cartilage gratfs can move out of place causing deformities years later, I have not known cartilage grafts to resorb. Good luck Dr. PG

There are a variety of cartilage grafts used in the nose.  My experience-  25 plus years-  is that autologous (coming from the individual's own body) can be considered permanent.  "Banked" cartilage  -  commercially available that is from another individual- does in fact resorb, but this is not used by experienced surgeons in my experience.

This is a very good question. Over the years, I have had many patient with septal grafts, ear cartilage grafts, rib grafts and bone grafts. As far as I can tell- they are all still in place. I have not seen any resorption.

Cartilage that is diced and wrapped in surgicel for dorsal augmentation tends to resorb completely in 6 months.  Cartilage used for tip grafts can warp and become visible but not resorb entirely.  It depends on the way it is used.  Infections are another consideration that can affect cartilage longevity.
