Hello and thank you for your question. This is likely the split in your lower lateral cartilage. This can be fixed. Based on your
photograph, you may benefit from a tip refining rhinoplasty. Your surgeon can
accomplish this by trimming, suturing, and reshaping the cartilage in your
lower nose. Cartilage grafts may also be used to help improve tip refinement.
The most important aspect is
to find a surgeon you are comfortable with. I recommend that you seek consultation
with a qualified board-certified plastic surgeon who can evaluate you in
Best wishes and good luck.
