Will a 5mm down advancement make my face too long?

Question

For a sliding genioplasty, I was told the doctor wants to move my chin forward 5mm and down 5mm. While I don't want my mentolabial fold to be too deep, is 5 mm down too much, or is the tissue itself going to look shorter ? I moved my jaw 5 mm downwards to try to simulate it and didn't like how it looked.

Michael P. Morrissette, DDS, FACS · Answer

You have a somewhat deep mentolabial fold and moving the chin down 5 mm will diminish the fold. If he is moving it forward 5 mm then the effects on the mentolabial fold will provide a good balance. You may need an advancement of 6-7 mm.

Barry L. Eppley, MD, DMD · Answer

You should always have computer imaging done before surgery to see how those dimensional changes would look. The simple test of jutting your lower jaw forward a bit is a good test of any vertical chin change. If you didn't like how it looked then that vertical chin lengthening change would not be a good one for you. What looks good to the surgeon may not always look good to the patient. Excessive vertical lengthening of the chin in women frequently is not a desirable effect that they like.
