Less wide nose sidewalls and nostrils? (photos)

I see what you are referencing.  The middle vault of the nose along with the lower 1/3 are slightly wide and bulbous.  Narrowing of the ala would help, but not solve the problem entirely.  You need to remove volume from the tip.  Narrowing the bones would also bring the middle vault in by some techniques that only experienced nasal surgeons can do.Please consult with a double board certified Facial Plastic and Reconstructive surgeon.

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.
