Can I have a sliding genioplasty (I was told my chin was too short)? (Photos)

You are an excellent candidate for a sliding genioplasty to both lengthen your chin and move it forward. You need more anterior projection than length. Patients with recessive chins always look short but that changes once you bring the chin forward. You should consult with another maxillofacial surgeon. We do this procedure in our office with intravenous sedation and it takes about an hour. It will not change your bite.

You can see a lot more than 5mm below your nerves, below apices of teeth, and reasonable alveolar support. Depending on your goal you may be limited to 8-10mm of advancement, so in that scenario we always talk to people about doing further advancement in the future or possibly a small implant. More important just make sure you and your doc have a similar expectation. If you want your chin to fall in line with your lower lip, that's jaw surgery plus genio. You should think about ortho too, improve some of your lower lip protrusion.

You appear to have a small lower jaw, retruded, small chin and bite issue. Very likely that advancement of both jaws, bite correction and chin advancement should be considered. Second and third opinion consultation with maxillofacial surgeon is recommended. Good luck.
