Chin augmentation surgery, also called mentoplasty, is a procedure that adds fullness to the chin. Genioplasty, on the other hand, is a procedure that rebuilds the shape of the chin to create a smaller size. The technique you receive will depend on your unique situation and goals. Additionally, a genioplasty can be performed to improve your dental bite and other medical concerns. Dr. Katzen will help you decide whether you should receive a genioplasty, mentoplasty, or a combination of both.
