Can the ball on my nose be reduced? (photo)

Hello and thank you for your question. 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.
  Make sure you specifically look at before and after
pictures of real patients who have had this surgery performed by your surgeon
and not just a computer animation system. 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 person.
Best wishes and good luck.

The condition you've asked about is called a bulbous tip and a tip rhinoplasty is the surgical procedure that reduces the size of the tip. what is done in the procedure is that the excess cartilage is removed and the remaining cartilages are sewn together, narrowing the tip. It is a common and straightforward procedure. Good luck!
