I had a silicone chin implanted 20 years ago. As I would like to have it changed for a bigger one I went to consult a ps. He told he has never seen such a big bone erosion and I should consult a maxillofacial surgeon. This doctor wants to remove the implant and in another surgery do a osteotomy to advance the chin. Is the erosion this big? Should the implant be really removed? Is the osteotomy necessary or I could go with a newer better located implant?

Answer: Chin Implant Malposition/Bone Resorption Options This is classic chin implant settling, not a true inflammatory erosive process. It is most commonly seen from the intra-oral placement of chin implants where the implant has been positioned too high over the thinner cortex of bone near the tooth roots. It is probably a process that is stable and further settling into the bone is unlikely from where it is now. Unless you are having tooth sensitivity, there is no urgency for removing it. If you do remove it, it can be simultaneously replaced with either a sliding genioplasty or a new implant secured in a lower better position with screw fixation. If a sliding genioplasty is chosen then it can be done intra-orally. (with a better incision location than the one you have now) If an implant replacement is chosen then it can be done from a submental incision on the underside of the chin. There is no reason to have separate surgeries for removal and any form of new chin augmentation. Given the size of the bone defect, it can be filled in with demineralized bone paste or granules to restore some bone thickness.

Answer: Silicon chin implanted 20 years ago causing bone erosion: What should I do? Only in person evaluations allow a determination if the aggressive bony work is needed. Good luck.///
