Possible Ear Cartilage Warping from Rhinoplasty?

Ear and septal cartilage are actually two different types of cartilage (elastic and hyaline, respectively) and have different mechanical properties. While any cartilage graft can warp (twist or deform over time), septal cartilage tends to be more useful structurally. You're also correct that most surgeon's--myself included--will use septal cartilage over ear cartilage, if it's available. Most patients undergoing their first (and hopefully last) rhinoplasty will have adequate septal cartilage available.
I'd be a bit suspicious of someone advocating ear cartilage first (unless the septal cartilage was too deformed, or had a large perforation). It makes me wonder if the surgeon is experienced at operating on the septum. And if he/she isn't, then that surgeon shouldn't be touching the rest of the nose!

Frank-
Ear cartilage is higly specialized, thin deformable cartilage that is used all the time for nasal surgery, mainly in reconstruction, and primarily in areas where fine-tuning needs to be performed. Warping occurs as the scars heal and contract over time...these forces can uncontrollably deform the cartilage and twist the results.
I am a big fan of ear cartilage in very specific circumstances or when other sources are not readily available, i.e. septal cartilage from inside the nose. Septal cartilage is very rigid and resists deformation over time better than ear cartilage. Again, both are great options in very specific indications. For tip elevation and a tip-plasty, I typically use septal cartilage if it is available. If it is not and we need structurally rigid support, I then move to rib cartilage.
Make sure you excert all your options and see as many Board Certified surgeons as you can to gather as much information as you can with regard to your particular case.
I hope this helps!
Good Luck-

You have asked some interesting questions. "Warping" is when the cartilage implant bends, or changes shape. This may happen to cartilage implants, but is not usually a problem with the strut you have described.
Ear cartilage is not very straight to begin with--so it's not my first choice for a tip strut. I prefer to use septal cartilage--which is generally much straighter. You mentioned that you had never had a rhinoplasty--but have you had a septoplasty--was cartilage removed from your septum? If so, this may be why the surgeon wants to use ear cartilage. If not, ask if the surgeon can use your septum as the donor for the cartilage.
