What's the best way to fix asymmetrical nostrils? (Photo)

Facial asymmetry is everywhere... if you look closely for it.If the asymmetry is not out of specification, there is no reason to 'fix' it.  Some things are better left alone.Surgery, however clever, will leave some tracks behind, some evidence surgery has been done.  This is particularly true about nostril modification.Well designed surgery should always have more plusses than minuses, so make sure you are aware of all the downsides before you proceed.  

Of course it depends on a patient’s specific circumstances, but typically an asymmetrical excision can be performed to even up the nostril size.

Rhinoplasty asymmetry in the thin skinned nose requires a VERY experienced rhinoplasty surgeon who knows how to do what is needed without letting it show. I often see noses like this that have been done that show every "nook and cranny". 

From the picture you submitted it appears that the asymmetry you are concerned with is essentially due to asymmetrical development of your lower lateral(alar) cartilages.. The lower laterals with their medial crura contribute to the size and shape of the nostrils and any gross deformity of it is easily noticeable..They also tend to get thicker and  larger with advancing age contributing to hard bulbous tip in older men. Your problem may be solved by a properly performed tip rhinoplasty.

There are significant asymmetries with the nose, however  a full set of photographs are necessary. The nasal bones are crooked which requires osteotomies to straighten them. The patient's left upper lateral cartilage is concave and will require a spreader graft to bolster it outwards. The nostrils  themselves are not all that asymmetrical.  A full  closed rhinoplasty will be necessary. For many examples of asymmetrical noses we have repaired in our practice, please see the link below to our rhinoplasty photo  gallery

Nasal tip asymmetry as yours is combination of cartilage and tissue issues.  Open rhinoplasty to fix the underlying issues is required.  This surgery is an outpatient procedure.

Assymetric nostrils can be corrected by either addressing a deviated nasal septum, realigning the medial crura (cartilage beneath the columella of the nose), and/or correcting the shape, width, and height of the lateral crura (cartilage underneath the side walls of the nose). Tip refinement can also be done at the same time. I would recommend consulting with a facial plastic surgeon to address your concerns.

Your posted views lack the profile view which is very important. From
your pictures, I believe that you will be a good candidate for standard Rhinoplasty. I am concerned about a possible septal deviation that needs to be ruled out.Using an open approach, your bulbous tip can be refined creating more symmetry in your alar cartilages. This will also make the tip in line with the dorsum of your nose.
