No, the 3rd one that is MOST used in maxfax bi max is the one that can disqualify you (from chin wing). The 1rst is the 'high' BSSO that the chin wing docs like.
ETA: They don't want to cut through the SPLIT area of that (3rd) BSSO. The split area on the 1rst one is HIGHER so the chin wing cut doesn't go through the split area.
So this is what I’m wondering. The first diagram below you see a traditional chin wing where the ENTIRE lower border is cut and dropped/ advanced. This adds vertical length to the entire mandible, which is what the procedure was initially designed for, so the cut needs to be all the way down which traverses the most common BSSO (3rd) cut. Bad.
In the second diagram the cut is made at the back, but what if instead of mobilizing the entire border the cut is stopped somewhere near where I drew the red line, so that it doesn’t traverse the BSSO cut. I mean in a side wing you don’t even want to drop the whole border anyway as you only want dropdown at the back, so the question is, would you need to mobilize the entire border even in a side wing?
I’m thinking you probably have to because the drop down needs to be gradual. I’m not sure you can aggressively bend down the back where my red line is drawn without cutting further down to allow for a more gradual dropdown.
This is probably why Dr. Z said BSSOs are problematic for both SWs and CWs.
