What can be done to make my nose and nostrils more symmetrical? (Photos)

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.  This can be designed to improve your nasal symmetry.  Cost varies based on geographic region and surgeon expertise.  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.

Judging from your photos, it looks like you may have some deviation in your septum, which can be corrected with septoplasty. As for your nostrils, the septoplasty may improve the symmetry or your tip can be refined to improve the look of your nostrils further. Cost and details should be worked out once you find an excellent facial plastic surgeon. I hope this helps.

I would recommend starting with a consultation with a board certified facial plastic surgeon that specializes in rhinoplasty surgery to discuss if rhinoplasty can address your concerns. 
I would recommend writing down the following questions before scheduling your consultation:
1. Are you unhappy with the tip of your nose? 
2. Do you feel that your nose is too wide? 
3. Do you want to make your nostrils smaller in appearance? 
4. Are you looking to decrease the general size of your nose?
I hope some of these questions will help you pinpoint what it is that you don't like about your nose.  Cost will vary due to many factors including: facilities fee and anesthesia fee. I wish you the best as you research your options when scheduling a rhinoplasty consultation.
Sincerely,

You appear to have a slight septal deviation that is causing the nostril asymmetry.  A rhinoplasty with septoplasty would be needed to recenter your tip and make your nostrils symmetrical. 

Thanks for your question.  The good news is that deviated noses and asymmetric nostrils can be improved.  Of course, there is no substitute for an exam, but based on your photos, I believe your goal is reasonable.  A rhinoplasty would address the deviated nose and also bring some added refinement to the tip and overall width of the nose.  At the same time, nostril narrowing could be done to both reduce your nostrils and make them more even.  An experienced surgeon with an artistic eye would be your best selection.  Cost varies by experience, complexity of the nose and region, so it would be impossible for me to estimate that for you.  Find the surgeon you feel is right for you first, then discuss cost.  I suggest you never make such an important decision based on cost.  Revisions are far more complex and the cost can be significantly higher (not to mention having a nose you don’t like).  I hope this helps, I wish you all the best!
