How much forward can genioplasty push the chin?

Chin implants can actually add 10 mm or more to the chin length, and sometimes can even be stacked to add more. A genioplasty can potentially add more length but is a more involved operation. Opinions stated here are only opinions. They are not based on a clinical exam, which is recommended.

Without an exam your question cannot be answered. However, your photos are helpful and you are probably a good candidate for a Chin Augmentation. You will need to see an Oral/Maxillofacial surgeon to see if othognathic surgery, genioplasty or using an implant is best for your specific case. It should be noted that patients with severely weak jaws or abnormally functioning jaws may be better treated with other facial surgery (orthognathic surgery), although a chin augmentation may be an option at a later time. These patients should seek the advice of a plastic surgeon to determine which course is right for them. Here is some information to help you make this decision:Candidates for Chin Augmentation -Patients whose chin profiles are weak but have normally functioning jaws are candidates for Chin Augmentation. Many of these candidates have used injectable fillers in the past to strengthen the protrusion of their chins, but are looking for a permanent solution. If you are one of these patients, then you are a likely candidate for chin augmentation.

How far forward a sliding genioplasty can move the chin depends on the thickness of the chin bone. It could be anywhere from 10 to 16mms in most cases. 

Hi, non smiling photos of your face from the front and side would help in the evaluation. I have performed many Chin Augmentations using chin implants for over 30 years.   A weak chin creates an imbalance making the nose appear larger, the mid face top heavy and the lower face look short that de-emphasizes the lips and allows early formation of a double chin.  Chin augmentation using a chin implant will add projection to the chin creating harmony and balance to the lower face.  I have found that placement of a silastic chin implant, through a small curved incision under the chin (also allows excess skin removal) to be very safe, quick, highly effective and far less invasive than a sliding genioplasty.  I perform chin implant surgery in 30 minutes or less, often using a local anesthetic alone.  In my opinion, you are a good candidate for chin implant surgery.  I have used large sized EAC chin implants, in males with very weak chins, that have achieved the desired chin projection.Hope this helps.
