I typically would prefer to do an osseous genioplasty in a younger patient. A chin with excess vertical height and inadequate projection can cause mental strain, or difficulty closing the mouth. I often prefer to do a sliding or "jumping" genioplasty to correct this. A jumping or oblique sliding genioplasty can decrease the vertical height and increase the overall chin projection. I find this to not only augment the chin, but to re-establish harmony amongst the facial proportions. In many circumstances, a chin implant will give an excellent result. I prefer to use them in a patient of skeletal maturity. In the case of a chin with excess vertical height, I would favor an osseous genioplasty.
