Why does nasal septal cartilage regrow after septoplasty or rhinoplasty and the tip cartilages do not?

The septal cartilage does not regrow after surgery when it is removed.  For this reason, it is important that cartilage that is removed is not structural in nature to the nose or it will lead to collapse of the nose.  Surgeons can place cartilage back in the nose after septoplasty which can allow better physiology of the nose but it will not lead to regrowth.

the septal cartilage does not regrow. If it did, then we could always reharvest the septum as cartilage graft material when performing revision rhinoplasties; if you have septal deviation, it is likely that all of the deviated septum was not removed on the first go around.

Dear Johann90779, Nasal septal cartilage does not regenerate after surgery. More then likely the deviated septum was not fully corrected during the septorhinoplasty. An consultation and intra-nasal examination would answer any of your concerns. Best regards, Michael V. Elam, M.D.
