Side profile? Jaw or chin too small? What can I do to improve it? (photo)

Either a sliding genioplasty or chin implant will improve your lower facial balance. Most men prefer a more prominent chin which provides a more masculine appearance.

Based on the photos, you seem to be a good candidate for a chin implant. However, a detailed evaluation through a physical examination is necessary. After that, a chin implant can be considered, and if there is enough fat in the cheek area, buccal fat removal (bichectomy) could also be performed. Additionally, to balance the lower part of your face, fat injection into the jawline area could be an option.

Based on what you posted, you appear to have a pleasing facial profile appearance. I'm not sure what you are dissatisfied with, however, I'm not sure that it chin implant would be a good idea in your situation. Please consider visiting with a reputable facial plastic surgeon so you could see which options might be best for you moving forward. Thanks to this question. Sincerely, Dr Joseph
