Wait until nose is fully healed to decide
As far as collapsing of the nose, this will not occur unless you sustain severe trauma to the nose. Collapsing of the nose will be most evident by a saddle nose deformity, which you obviously do not have at this point. This would show up immediately after the surgery if it were going to occur. I would not recommend removing and replacing any ear cartilage grafts unless they are causing severe problems in the nose because of the extent of revision rhinoplasty work that you have had done. Do not make any judgments on this nose until after one year of full healing, and then consult with your original surgeon.
You might benefit from an Injectable Filler treatment.
Revision rhinoplasty is one of the most challenging, and humbling operations I perform. It would be best if this surgery were your last, since your surgeon needed both ear, and septal cartilage after removing the silicone implant.
You can have injectable fillers safely placed in your nose to correct minor assymetries that are visible at 3 months after rhinoplasty.
I didn't get a clear picture of how your nose looks, or what's bothering you, so feel free to email me a full facial picture with a description, and I'll be happy to share my thoughts.
I've attached a link to my Non-Surgical Rhinoplasty page for your perusal.
I hope this helps, and best regards.
Revision rhinoplasty takes time to assess
You had revision rhinoplasty only three months ago so it is too early to assess the results. Most surgeons would wait a full year before considering re-operation. Operating before waiting that long makes no sense because it takes that long for the nose to fully heal, and sometimes longer. Complete healing means that the scar tissue has matured, the swelling has gone out of the nose, and the cartilage has been integrated into the tissues. Early on, the nose, especially the tip, often feels firm and stiff. Your physicin can determine when it has recovered enough to consider further improvement.
It is to soon to assess any results and you must wait at least a year for any revision rhinoplasty surgery. Be patient and discuss the many options of autologous materials available with your surgeon. Best regards!
You should wait at least one year before having further revision surgery on your nose. You can have more autologous grafting material (other ear cartilage, fascia, rib cartilage).
As long as your surgeon maintains adequate dorsal septal cartilage support, your nose should not be in danger of collapse. The main sign of nasal dorsal collapse is progressive lowering of the profile in the middle third of the nose.
Good luck and be well.
It's easy to say but BE PATIENT. The worse thing yo can do is to rush into another procedure before the results of the revision have been fully matured, that is the scar tissue internally and tissues have matured and the transplanted cartilages have been fully integrated. You definitely wil continue to see changes over the next 6-9 months. Only after the 9-12months post op period can a true assessment be made as to what needs to be done to improve your situation (if anything). There may be other soft tissues that can be used to augment the areas of concern without resorting to cartilages.
Allow time for current grafts to take
AS others have advised, I concur and beleive that you could cause more damage by intervening too soon.
Give it time for the current cartilage to take.
There are many different sources for autologous materals as mentioned: fascia, dermis, cartilage, etc.
