Obviously there are differences in the way noses look between Caucasian people and people of ethnicity, but are there differences in the anatomy of the nose as well that come in to play for rhinoplasty?
Yes there are definite structural differences and often skin thickness and texture differences. Ethnic noses tend to have shorter, flatter nasal bones, absent caudal septal cartilage, flatter tip cartilages with weak medial crura and thicker skin with increased subcutaneous fat in the tip. Nostril width is often increased as well. All these factors need to be considered in planning for the surgical result.
