Vertical indented line down nose and uneven bridge, profile different from each side- surgery 2 years ago, used cartilage graft?

You would really need pictures or an exam to be able to ascertain what needs to be done. Find a plastic surgeon with ELITE credentials who performs hundreds
of rhinoplasties and rhinoplasty revisions each year. Then look at the
plastic surgeon's website before and after photo galleries to get a
sense of who can deliver the results. Kenneth Hughes, MD Los Angeles, CA

Pictures will be required to evaluate any potential for revision rhinoplasty. Its best to obtain your Medical records and operative report to find out what was performed during the rhinoplasty procedure. Also best to look for a very experienced revision rhinoplasty specialist in your area.

It sound like you intended to submit pictures, however none appear. There are numerous reasons why irregularities can exist after rhinoplasty, and typically these do not always present until such time as you are describing some two years later when skin contraction and wound healing are complete, along with the effect of advancing age with thinning skin. I would suggest that you return to your surgeon to get his input. If you had a cartilage graft there must have been some predisposing issues to being with. sometimes these grafts can become visible creating some of the irregularities that you are experiencing. Alternatively, there can be asymmetry in the way you nasal bones were fractured. Nevertheless there may be some minimally invasive treatments that can provide camouflage. Hope that is helpful.

Of course, without seeing we can only guess as to what the problem looks like, and how it might be fixed. Irregular areas can occur after rhinolasty, more often felt than seen. If there is a dent that troubles you an exam is the best way to sort things out.
