Round nose tip and nostrils, is it possible to reshape it? (Photos)

Thank you for your question.  Simply put, a nose can be surgically reshaped assuming the patient is healthy, has reasonable expectations, and has anatomy favorable for a surgical procedure.  The critical thing for the patient is seeking out an experienced Rhinoplasty Surgeon. Seeing photos is not sufficient to give you a complete answer, so I would recommend that you seek out a few in-person opinions. 

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.   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.
