Is this inverted V deformity? (Photo)

Based on your photos, your cartilage bridge is a tad lower than the bony portion of your bridge and this is causing an indentation and lines. Depending on your examination, microdroplet Silikon-1000 injections maybe considered for adding needed volume to the mid portion of your nose and for correcting the issue that is bothering you. I hope this helps! Sincerely, Dr Joseph

Your plastic surgeons description is correct. Your nasal bones sit outside the line of the cartilage of your septum and the spread graphs that were placed. A filler can be placed to camouflage this area and this is a temporary solution. A more permanent solution would be to have a revision of your rhinoplasty so the bones could be brought into the correct alignment. Done correctly, this should be a permanent solution to your problem. Discuss this in detail with your plastic surgeon. Best wishes.

Rhinoplasty surgery is challenging. As the nose heals it's possible things can shift resulting in a less than ideal result. I can only really see the sides, but it does look like your upper lateral cartilages are disarticulated from the nasal bones. Since you are more than a years out, I would recommend you speak with your surgeon about a revision surgery or get a second opinion from a different Facial Plastic Surgeon in your area who specializes in Rhinoplasty.
