Chin implant after Sliding Genioplasty, possible or not?

Question

I've had Sliding Genioplasty, but despite my chin being moved forward 1cm I feel the deficiency is still too prominent. Would like to have an implant inserted to gain another 1cm. I also feel the Sliding Genioplasty wasn't done well because the labiomental fold now appears to be very, very deep, with the chin below it very pointy, and the tell-tale hourglass deformity on the sides of the chin gives me a "wavy" jawline. Will an implant help, and do you recommend silicone or Medpor? Thank you.

Without an exam your question cannot be answered.  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

Good Day. Thank you for your question.Answer: Yes.A sliding genioplasty usually produces a paramedian or lateral mandible deficiency, since the bone is cut and pulled forward. This volume deficiency can be repaired with soft tissue filler placement (radiesse and bellafill best).If the anterior projection was insufficient, as it appears in your case, more anterior projection is indicated.The options for anterior chin projection after the osteotomy are: (Its best to ensure the anterior bony surface is smooth with a cutting burr, if necessary)1. Bone on-line graft- take hard bone (cortical bone) from the outer table of your skull (easy than you think, takes 20 minutes), and lay the bone grafts on the mandible, fixed with a titanium screw.2. Silastic chin implant- in some cases as custom or patient specific implant can be fabricated from a 3D CT scan of the face and mandible to make it more precise.3. Medpor or Gore-tex grafts- I do not prefer this material because the increased complication rate and if one wishes it revered, difficult removal from th overlying soft tissue.In summary, a silastic chin implant can be easily accomplished after a sliding mandibular osteotomy. Other alternatives such as bone on-lay grafts, fat transfer or fillers can be performed.Good luck with your choices.
