Chin augmentation (Mentoplasty) using surgical implants can alter the underlying structure of the face, providing better balance to the facial features. Surgery can be used to make chins smaller in size (Genioplasty) or larger through the use of cheek implants (Mentoplasty). This operation is often, but not always, performed at the time of rhinoplasty (nose job) to help balance the facial proportions. Chin Implants can be made of silicone or other man-made materials or in some instances tissue from the patient’s body can be used.
