Am I Good Candidate for Alarplasty? (photo)

The width of the base of the nostrils must balance with the size of the tip, and the distance between the eyes, or the intercanthal distance.  If your nose is in the middle of the three pictures, a combined Weir/sill incision would best address the width and flare of your nostrils.  

The alar base can be narrowed by removing a wedge of skin and soft tissue and carefully closing the incision.  The location of the excision determines the effect.  When the excision is taken from the nostril floor, this results in reduction of inter-alar width, or the horinzontal distance between the nostrils.  When it is taken from the alar side-walls, it reduced the alar flare, or curvature of the ala.  It looks like you could benefit from a bit of both. Best of luck

I agree that the base of your nose is too wide.  A surgeon could consider narrowing the nostrils and reducing alar flare.  This would decrease the width of the base of the nose.  The scars are hidden where the nose meets the face and within the nostril.
