Absorption or Wrapping After Revision Rhinoplasty?

If its been a year and the profile is good, its unlikely there will be absorption at this late stage. Not impossible however. But there would need to be something like infection or trauma to cause it now.

Warping of cartilage is a recognized complication of a revision or primary rhinoplasty.  The amount of warping or asymmetry can be seen early or as a late complication of surgery.  These changes in cartilage sometimes cannot be predicted.  I also perform a diced cartilage graft to the nose that may have lesser degrees of warping and shifting than larger pieces of cartilage. 

This far out from surgery it is very unlikely that your cartilage graft will resorb or warp. Warping, if it were to occur, usually occurs earlier on in the postoperative course. The blood supply to the cartilage should be well established at this stage so resorption is rare at this stage in the healing process.

In revision rhinoplasty, it is usually necessary to reconstruct and reshape the nasal framework using cartilage grafts. Because available septal cartilage has usually been removed during the first surgery, grafts must obtained from either another site - the ear or the rib.
In the absence of infection or trauma, neighter ear cartialge or rib cartialge absorbs to any appreciable extent. Rib cartilage does have a tendency to warp (curve) -- ear cartilage does not exhibit this same tendency.

Cartilage grafts are commonly placed for rhinoplasty. Yes, they can warp and resorb. Usually cartilage harvested from yourself, if it has not curved or resorbed at this point, you probably are OK.
