Sliding Genioplasty

Q: Dr. Eppley, I’m a 32 yo man going for a sliding genioplasty. .I have lip incomptence therefore the surgeon is planning to remove a 5mm wedge of bone and I asked him to move the chin 10mm forward. However I’m a bit afraid of removing that amount of bone. I’ve read that with an angled genioplasty is also possible for height reduction but he seems reluctant because of the notch left on the jaw. I don’t know if these two procedures give the same result. The second picture is approximately what I expect and since I’ve had time I ‘simulated’ it on the x ray. Even though I rely on him, I’m looking for the best result that’s why I’m asking for another thought on it. Thanks for reading.

A:Please send me pictures of your face from the side view. That will be helpful to see how much vertical chin height reduction is needed if any in your sliding genioplasty procedure. If you really need vertical height reduction it is better to do it by a vertical wedge resection than a severely angled bone cut. That is the more assured method of achieving adequate vertical chin height reduction. Ideally seeing pictures of your lateral cephalometric x-ray would also be most helpful.
