Is there a chance my nasal bones or cartilages shifted (moved) after my rhinoplasty? (photo)

It appears that you have an inverted v deformity, and may benefit from spreader grafts.  This should help with better aesthetic lines, and your breathing, as well.

 Judging from your results, it appears that your crookedness comes from an incomplete osteotomy. I often see this in patients who have had their nose done and approximately  six months to one year have a crooked nose. More times than not their primary doctor tells them that it was due to a shifting of the bones or that the patient hit their nose. This will likely not change and will be more noticeable as the swelling goes down. My suggestion is that you talk to your doctor and if you are not satisfied seek a second opinion.

This is referred to as an inverted V deformity when the upper lateral cartilages separate from the nasal bones.  The correction involves a rhinoplasty and cartilage grafts.  

I don't really see much difference between your before and after photographs. Did you go to a rhinoplasty specialist?

Thank you for the photos and I agree with others that you may have an inverted V deformity or in complete osteotomy so see your surgeon or other expert and be evaluatedDr Corbin

Dear salvamea, I would suggest that you seek consultation with some experts in the field of revision rhinoplasty or discuss your concerns with your surgeon. You will need some correction to address the asymmetry. Best regards, Michael V. Elam, M.D.

It is unlikely you will ever know the cause of your post-op problems but you do have an Inverted-V deformity and asymmetry of the nasal bones. I suggest you consult with your surgeon or another revision specialist to discuss your options re possible revision surgery.
