Gender Facial Affirmation Surgery; Techniques for Feminizing the Chin

The shape and size of the chin are very important in feminizing the lower third of the face, and osseous genioplasty is commonly used in FFS. Different variations of the osseous genioplasty can be used to feminize the chin. The 1-piece genioplasty reduces the size and rounds the chin. 2-piece genioplasty reduces or increases the projection of the chin, but retains the same shape. 3-piece genioplasty also reduces or increases the projection, but has the additional benefit of narrowing the chin. This narrowing helps to create the "V" shaped lower face that is often desired by patients seeking facial feminization. Protection of the mental nerve and resuspension of the mentalis muscle is essential to prevent permanent lower lip numbness and ptosis respectively.
