Does nose cartilage have "memory"?

 Yes, cartilage and bone can have memory, that's why this is important to seek out a rhinoplasty specialist for best results. A busy round plastic surgeon has dealt with this issue many many times in the past. Impossible to remove scar tissue. Cartilage  structural grafts can help with warpage and movement, however it's important to understand that three-dimensional contraction forces of  the healing  process can have effects upon the memory as well.

Yes, cartilage has memory and may fall back into their original shape. Most of the time sutures control their shape once placed as grafts.

Cartilage does have memory, but when it has been reshaped via sutures it will retain that shape after the sutures have either disappeared in the case of long acting absorbable sutures or when permanent sutures are removed. This occurs because of the scar tissue that is formed during the healing process after an operation. It is unlikely that, by removing sutures in a revision rhinoplasty, your nose would naturally come back to its original shape and position. Your surgeon would have to reshape the alar cartilges inot their new and desired position. I hope this helps.
