This will depend on the natural shape of your chin beforehand. If having increased chin width that flows smoothly into the back part of the jawline behind the chin, you would need to consider aa square chin implant style instead.

Yes. The genioplasty would work well to achieve good proportional balance to your face. Don't hesitate to speak with a Maxillofacial surgeon
