Can A Sliding Genioplasty Achieve 20mms Of Horizontal Chin Projection?
Q: Dr. Eppley, I’m thinking about scheduling a consultation with you guys, but before I fly all the way to Indiana I have a few questions.
With your custom chin implants how many mm will the jaw be extended? I need about a 20 mm extension. I know that’s not common, but I was also thinking doing a sliding genioplasty procedure for more extension. Is it possible to get to get the projection I want with those two procedures?
A: Thank you for your inquiry. To get to 20mms of horizontal chin lengthening the backbone of that procedure would be a horizontal sliding genioplasty done first of 12 to 14mms, followed by either a second sliding genioplasty or a custom chin implant. The stretch of the soft tissues will not permit an immediate 20mm of horizontal chin lengthening. The custom chin implant would be the preferred secondary chin procedure as it could address the narrowing effect of the large sliding genioplasty movement.
