1. What is a chin shield osteotomy:
A chin shield osteotomy is a modified form of genioplasty where the bone segment is shaped and moved in a way that affects more than just the tip of the chin. Instead of only pushing the chin forward or adjusting height, this technique allows changes to the entire anterior lower jaw contour. It can improve projection, vertical dimension, and the transition between the lower lip and chin in a more controlled and comprehensive way.


2. What it does:
This technique can create a subtle clockwise (CCW) rotational effect in the lower face, improving overall balance without touching the bite. It enhances lower facial support, refines the chin shape, and can smooth out the mentolabial area. Because it works on a broader segment, the result often looks more natural and integrated with the rest of the face.

3. Why in some cases it is a better option than bimax:
In many cases, the lips already sit relatively close together and the bite is acceptable. In those situations, full bimax surgery can be more aggressive than necessary. A chin shield osteotomy can achieve a similar aesthetic improvement in the lower third without moving both jaws. It targets the area that actually needs correction instead of changing the entire structure.


4. Effect on the mentolabial fold:
One of the main advantages is how it handles the mentolabial fold. With bimax, depending on the movements, this fold can become deeper and more pronounced. A well-planned chin shield osteotomy can maintain or even improve this area, leading to a smoother and cleaner look between the lower lip and chin.


5. Gives BSSO effect:
Although it does not move the mandible like a BSSO, it can create a similar visual effect in the lower third. By increasing projection and support, it gives the impression of a stronger, more forward lower jaw, without actually altering occlusion.


6. When it is used:
It is mainly used in cases where the issue is aesthetic rather than functional. This includes chin retrusion, lack of projection, vertical imbalance, or a poorly defined lower third, while the bite itself is already fine.

7.Results:

1777158300576
1777158312993

1777158401845
1777158409975


Some of those results needed bimax instead of chin shield osteotomy.


8. Final point:
This technique is underrated and not talked about enough. In the right cases, it can give a refined and balanced result without the need for full jaw surgery.

1) Not enough results and not widely practised by surgeons

2) The available results have been done on people who are downgrown who should've done a jaw surgery - so this is really only benefits a certain type of growth pattern and even then the results are mid

3) The white blonde woman had lip incompetence, a standard genio would've produced the same result - advancing the chin forward lets her lips meet which means it isn't rolled out anymore (so the mentolabial fold gets shallower from that alone but deeper with the advancement so no overall significant change to the mentolabial angle)

It's nothing special imo

There are 2 parts to the mentolabial fold being the chin and the teeth - start thinking outside the box and you will know exactly what to do if you have these issues :feelshehe:

Yes my original point was talking about some people who need it, usually the one's who have their chin reccesed and their mentolabial deep, but wouldn't suggest it to everyone.

Would have loved to see some cases that i was talking about but it's only people who needed bimax that did shield genio.

Many of these people in the post have chins that are already compensating for a small jaw, making the mentolabial fold worse too. LJS would be needed combined with genio for most
