Chin Implant Vs Sliding Genioplasty

Great question.  This comes up quite often in consultation.  The preferred method is chin implant in the vast majority of cases.  With sliding genioplasty you can get projection and add some height, but it requires fracturing the bone and adding hardware such as plates and screws to secure in place which creates swelling for weeks.  The problem with a sliding genioplasty, besides the risks and downtime, is that it doesn't really provide much lateral augmentation on either side of the chin.A chin implant can add vertical height (we have implants that can do this as of 2017), lateral augmentation, projection, or it can be customize to add more laterally than centrally.  The biggest advantage to chin implants is the fact that they can be easily reversed by taking the implant out in the office under 5 min if the patient doesn't like it.  The risks, in my opinion, are less, downtime is less, and the procedure is reversible.  

Hello,This is a topoic that you will get different answers from different specialists.  First you have to make sure that the problem is chin and not the jaw. Once that is rule out, then you can start deciding on the two options. I believe you can get the same projection with both procedures.  I do not think placing a large implant is a good idea.  If  more than 5-6 mm of chin advancement  needed, jaw surgery would probably be the ideal surgery to begin with. The vertical positioning depends on your facial height. This should be measured on X-rays and clinically. If height needed, then S.G. is the only way to go.

Chin implant versus sliding genioplasty is a big decision. A chin implant is inserted for cosmetic purposes up to about 8 or 9 mm of anterior projection. Chin implants to give a few millimeters of added height and width, since the implant is three-dimensional. Chin implants are placed through a sub mental  incision under local anesthesia as an outpatient procedure. A sliding genioplasty is performed under general anesthesia and usually requires an in-hospital stay for 24-48 hours after the procedure. It's best to perform this procedure when the teeth are significantly out of alignment and  there is a significant bony deficiency present, and more than 10 mm of augmentation is required.
