Those who are undergoing gender change surgery, need to undergo a nose reshaping procedure. It adds brilliant characteristics to your nose as per your gender.
In the case of MTF, the nose of the female is made narrower and the tip is made blunt. So the procedure will aim at reducing the size of your nose and making it narrower along with sharpening the tip of the nose.
If it is FTM, the nose is made wide and the masculine characteristics will be added to the same.
