How would I fix large nostrils and a flat nose? (Photo)

Do not even think about injecting ANY fillers in your nose... at your own risk!About your case, the bridge seems not bad and the problems are centered on the lower third of the nose, needing:-nostril reduction (done with a wedge excision at the base of them)-support grafts made of cartilage taken from ears or nasal septum, to rebuild the lower third and enleghten your nose and give the projection desired-tip graft to reshape it to more occidental style-maybe tongue in groove or other variations are applicable

 A rhinoplasty for you would involve narrowing your nostril base refining the tip and increasing tip projection slightly as well as narrowing  of the bridge. See a very experienced rhinoplasty surgeon for this who can show you many examples of his work in noses like yours.

Based on your photo- you appear to be a very good candidate for rhinoplasty. Fundamentally, to achieve your goals- you will need standard cosmetic rhinoplasty techniques. This includes: refinement of your tip, narrowing of the bones, improvement of your profile and narrowing of your nostrils. You may also need a tip graft in order to give your tip slightly more elegant look. I've done this many times- in the right hands you should achieve your goals.

The rhinoplasty procedure can narrow wide nostrils with an alar-plasty. This involves removal of a wedge of skin at the base of the nostril. Osteotomies of the nasal bones will narrow the bridge line. A cartilage graft  added to the top of the bridge will increase the height. Synthetic, Silastic implants are used in some cases where there is not enough cartilage available.

The
areas that concern you can be realistically improved.

Keep in mind that following advice from a surgeon on
this or any other website who proposes to tell you exactly what to do based on two
dimensional photos without examining you, physically feeling your tissue,
assessing your desired outcome, taking a full medical history and discussing
the pros and cons of the operative procedure would not be in your best surgery.
Natural appearing results need to be individualized and what is appropriate for
one patient is not necessarily the best for someone else. I would suggest that
you find a surgeon certified by the American Board of American Plastic Surgery
and one who is ideally a member of The American Society for Aesthetic Plastic
Surgery (ASAPS) that you trust and are comfortable with. You should discuss
your concerns with that surgeon in person.
