Should I move my chin upwards with sliding genioplasty, disregarding the "1:2" ration between philtrum and chin? (Photos)

Question

I saw an oral surgeon and had a consultation about genioplasty. His suggestion was to move my chin upward & forward so that my philtrum and chin will be about the same length. But I found on the internet that the ratio between them should be 1:2 (as the attached image). He told me the ideal ratio depends on the person, but I'm not sure because men's chins are usually long. Should I move my chin upward? Is it fine for me to disregard the philtrum: chin 1:2 ratio? Thank you for your advice.

With a steep mandibular plane like yours, an advancement genioplasty will also give the appearance of a shorter lower facial height and improve your lower facial balance. In addition, it will reduce the mentalis strain and provide a strong masculine chin. You will require a maximum advancement of 10 mm.

While numbers and ratios have a place in aesthetic facial surgery, in the end what matters is what it looks like regardless of what the number say. The question in your case is whether the chin should just come forward or be vertically shortened as well. This is where computer imaging is essential. What does it looks like with either type of chin movement? You are the best judge of what looks best on your face. You should not have the surgery without computer imaging to make that determination.

From your sideways view the angle of your mandible has a serious downward tilt.  some of this may be semantics. A forward advancement based on the angle of your mandible is very different than the forward advancement based on a horizontal line.

If your oral surgeon has the skill and experience to do these procedures well then I recommend you let the driver do the driving.
