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.
