Can Closed Rhinoplasty Fix my Asymmetrical Nostrils?

Achieving symmetry is a near impossible goal and if that is what you are seeking it is very likely you may be disappointed. Attempting to diminish the degree of asymmetry is a more reasoanble approach. If you are having second thoughts and your nose is "not that bad", it sounds as if you should defer surgery for now. Your words indicate that you will be looking for any asymmetry which you will find upsetting.

Hi Adria,
Asymmetric nostrils are difficult to even exactly. Rhinoplasty will change your nose for the rest of your life. As you know, it is not like a haircut where if you don't like it, "it will grow back". In some individuals, a slight asymmetry can be corrected with injectable fillers, something to consider until you are surer of having rhinoplasty.
Make sure that you have given your rhinoplasty great thought before having the surgery. It is important that you have communicated to your prospective surgeon what bothers you about your nose, and what you would be satisfied with after surgery. Be absolutely certain that your surgeon is "on the same wavelength" as you, and that your surgeon is confident that your goals can be achieved.
Those before and after noses that are scaring you should not be from the surgeon that you are considering. Get multiple consultations. Do not have your surgery until you feel certain that you are ready to have it.
Be well.

Any time a patient is having second thoughts it is important to hold off on surgery. This gives you time to re-evaluate and figure out exactly what your concerns and fears are and then discuss them with your surgeon before surgery and not after surgery.
The nostrils can be made symmetric with close or open approach rhinoplasty. It all depends on the extent of the deformity. In some really bad noses or cleft palate related deformities of the nose or secondary (repeat) rhinoplasties an approach is preferred.

Most often, failure in correcting deviated noses lies in failure to correct the nasal septum. New deviations that occur after Rhinoplasty also often involve failure to correct the nasal septum.
The nasal septum is a large structure, the base of which lies just behind the columella (the skin between the nostrils). Deviations to the lowest or caudal part of the septum can create nostril asymmetry.
This is usually corrected using a caudal septoplasty technique. This should be independent to other changes you are seeking to achieve in the nose.
Make sure your surgeon is well versed in septoplasty surgery and you should be OK.
Best of Luck

Closed rhinoplasty can fix asymmetrical nostrils, but it depends on the degree of asymmetry of the nostrils themselves. Sometimes a simple alarplasty can be performed to further balance the nostril shape and width. Asymmetrical tip cartilages can also cause asymmetrical nostrils, and this can be addressed through a closed rhinoplasty as well. It is important to know what is causing the asymmetry and to embark on a surgical plan of action to correct the underlying problem.
