The major difference between male and female rhinoplasty is; the difference in the expectation of "ideal nose" for men and women.
Most men want a more prominent, strong nose with distinctive properties. For men, the tip of the nose is expected to be more low. The angle between the upper lip and nose is between 90 and 95 degrees.
On the other hand, women often prefer a upward-rotated nose tip. However, today's ideal female nose is flatter and longer than the past, so many women prefer a more natural look.
