Is This a Mestizo Nose? (photo)

While you have some features consistent with a mestizo nose such as a broad and somewhat flattened tip and wide nostril base, it is reasonable for you to undergo a rhinoplasty as your photos demonstrate that you appear to have a firm bony structure which lends itself to good support. I would recommend a facial plastic surgeon with expertise in reduction rhinoplasty.

The rhinoplasty procedure is different for each individual nose.  The procedure involves narrowing and refining the tip to give more tip projection and reducing the cartilaginous hump.  Thick olive oily skin requires cortisone injections and Blenderm tape in the immediate postoperative period so as not to get a pollybeak.  It is also important to release the depressor septi ligament in the tip so that the tip does not pull down upon animation and smiling.  The rhinoplasty is performed under a brief general anesthesia lasting 1 to 2 hours.

Based upon the posted photos you are a minor component. Best to seek in person evaluations from boarded docs in your city.
