Rhinoplasty on African Americans has long been a significant part of my medical practice. It's important to take into account all of the support and skin thickness issues unique to each person and from your photo I can find several characteristics of your nose that will require advanced rhinoplasty techniques.
It's important to find a rhinoplasty specialist who has dedicated a significant portion of their practice to the discipline of rhinoplasty. That surgeon will have performed many different ethnic rhinoplasties.
Drs. Patrick Byrne (Johns Hopkins), Jamie DeRosa (Boston), Mark Constantian (New Hampshire) are all experienced, skillful, ethical rhinoplasty experts.
