Chin augmentation using surgical implants can alter the underlying structure of the face, providing better balance to the facial features. This operation is often, but not always, performed at the time of rhinoplasty to help balance the facial proportions. Chin augmentation may be achieved by manipulation of the jaw bone (mandible) and augmentation utilizing this technique usually provides a more dramatic correction than with the use of prosthetic implants.
Chin implants are to build a better profile. Patients own bone is donated from ribs and from part of the pelvis. Unfortunately, use of donated bone implants in chin augmentation, even the patients own, appears to be associated with a higher rate of infection, even after the implant has been in place for decades.
