Can steroid injections lessen size of a visible cartilage graft? (Photo)

Hello,
At three months post op from a revision rhinoplasty there is still a significant amount of swelling. Steroids by definition work to reduce inflammation.  I recommend returning to your surgeon and allowing him to asses the need for injections or watchful waiting.  Based on the information you've provided I would recommend the latter.
Regards,

Typically no. Steroid injection will tend to thin the skin and do little or nothing to the cartilage graft. The result is likely to make the cartilage even more obvious. Best to wait and see how things settle done.

Steroids are not a good idea because they will not change the cartilage and may cause problems with the skin.

Steroid injections can be used for swelling, but not to dissolve cartilage.  It is best to wait this out.  With time I suspect you will not be able to palpate the edge of the septal graft.  Your body will form scar tissue around the graft.  In addition the graft will usually shrink over time.  Best to wait this out.
