Sliding Genio, Grafts, & Bone Paste/HA?

Sliding genioplasty  of 3 mm typically does not require bone grafting or hydroxyapatite paste. The genioplasty can be designed not to lengthen the face. Please seek consultation from surgeons have experience with sliding genioplasty 

At a 3mm sliding genioplasty you would not need a bone graft. Hydroxyapatite granules or cement (HA) can be placed into the slight step-off to build out the sulcus. HA augmentation of the jaw angles is challenging and will not create the same effect as an actual jaw angle implant. It can be done but expect more of a rounder jaw angle effect than an angular one. Only in cases of extreme chin movements would a bone graft be used. The angle of the osteotomy cut in a sliding genioplasty as well as the plate and screw fixation used can control the vertical change in chin length whether it be longer, shorter and to say the same.

Advance sliding genioplasty make your face looking longer.You need 3mm advance with 2-3mm vertical shortening to avoid looking longer.You don't need anything to your sulcus because sliding advance also make your sulcus smooth.HA is hydroxyapatite and it called "bone cement" I don't recommmend HA. Silicone or Medphore implant is better to your angle.

You should not rule out a simpler silastic chin implant. Simple, quick, cheaper and reversible.It can be done with local anesthesia in the office. Healing is rapid
