Is LJS better than bimax for recessed-mandible-cels?

[hansmoleman]

Assuming a sub-optimal but decently placed maxilla and a recessed mandible, is it sometimes better to get just a LJS instead of a bimax?

Reasons: easier to plan (just linear advancement exactly equal to the pre-op overjet, even a monkey would be able to plan it), easier to execute, literally no room for botches. If your maxilla and nose are decent, you know for sure you are not going to screw them up. It can also be combined with genio if needed.

TLDR: renounce to chad jaw to be 100% sure you are not dogmaxxed and you keep your dimorphic nose angle.

Never heard of LJS I’m gonna research

Lower Jaw Surgery (aka BSSO). So half a bimax

Oh , then I know that

That's what I'll probably get if everything else that I try doesn't work. Not sure if I need bimax or not as I think that my maxilla is atleast somewhat decent

I don’t see the point personally.

No significant difference in cost or recovery. Might as well get that perfect lower maxilla while you are in there.

There is significant cost difference (2x in some cases). But I’d never choose LJS for the cost. I’m basically scared of botching a mediocre but okay maxilla + nose. 3D movements are extremely complex to plan.

Worrying about this as well

In other words, say that you have an overbite, and you can clearly see it on a side picture because your upper lip protrudes. If you morph the lower jaw going linearly forward until the lips match (and optionally, move the chin with the genioplasty movements), this can be an accurate prediction of the surgery outcome (perhaps whether skin sagging/double chin will decrease more or less is a bit more difficult to predict exactly, but you can get an idea).

On the other hand, if you try to morph a bimax it’s going to be almost impossible to predict the outcome. Hell, even with advanced soft tissue 3D simulations it’s difficult. How does the nose change? How do cheeks change? What’s going to happen with the rotation? Top doctors use advanced software to predict these outcomes and even then they sometimes fail.

Of course, all this uncertainty is worth it if your maxilla is shit. My question is whether it’s also worth it if your maxilla is like 6/10.

don't go for BSSO it's shit, only combined with LF1 it got results

i can share my bimax and BSSO wouldn't do much job really https://yourimageshare.com/ib/BiW62wVl3O if you are about to do this do full surgery

Your before was not bad, not even recessed. Your post is great provided you have enough upper third support not to be doggmaxxed (can’t be fully seen in the picture). Anyway, you never know with just the simulations, perhaps you were just lucky.

I still haven’t decided yet. But I don’t want to be dogmaxxed, and personally I’m not a big fan of especially protruding philtrums (mine is not flat, it’s very slightly protruding, which in theory is not optimal, but I’d rather have that than be monkeymaxxed).

Do you think BSSO minimizes the bimax effect of flattening your face (unless it’s bimax + cheek implants etc)?
