What rhinoplasty options are there for me? Am I a good candidate for an alar base reduction?

Though you mentioned
you don't need your bridge addressed, the balance between your bridge, tip and
nostrils is critically important in creating an attractive nose. Often the thickness of the skin requires increasing the projection of
the tip of the nose, in addition to reshaping the cartilage, to increase its
definition and size.Consult with an experienced rhinoplasty specialist and
look carefully at his/her Before/Afters to find a surgeon with the aesthetic
that matches yours.

Yes. You appear to be a good candidate for rhinoplasty. One point of discussion for you to discuss with your surgeon is that you appear to have fairly thick nasal tip skin. This will, to some degree, limit the amount of refinement that is possible with your tip. However, tip modification and nasal base reduction should create significant improvement in the size and shape of your nose. Best.Stephen Weber MD, FACSDenver Facial Plastic Surgeon

Improving the nostril width is a frequent request of patients wanting nasal refinement. It is possible to
improve the cosmetic appearance of the nostrils alone without altering the rest of
the nose in some patients. Whether the optimal option in your particular
situation would be a tnostril base reduction alone or a full rhinoplasty would best be
determined at a consultation. 
Following the advice from a surgeon on this or
any other website who proposes to tell you exactly what to do based on limited
2 dimensional photos without examining you, physically feeling the 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
interest. I would suggest you find a plastic surgeon with extensive nasal
surgery experience who is certified by the American Board of Plastic Surgery
and ideally a member of the American Society for Aesthetic Plastic Surgery
(ASAPS) or a facial plastic surgeon (ENT) that you trust and are comfortable
with. You should discuss your concerns with that surgeon in person.
