My BSSO advancement was 7 mm

is it considered a big advancement? it says here submitted to advancement and counter-clockwise rotation bimaxillary orthognatic surgery.Bilateral saggital split osteotomy with an advancement of 7 mm and posterior extrusion of 4 mm at the level of the 2nd molars.Maxilar osteotomy of the type Lefort 1 with advancement and rotation. Doesnt say how much maxilla was advanced though.

No sliding genio was done. Just wondering how big of an advancement was achieved.

Mine was 10 mm. I'm guessing most people have from 5-10mm.

My plan exactly actually! Did you have an open bite too? Riley model is 11-13mm posterior airway space (PAS) so surgeon advanced to hit the top end of that spectrum. Over advancement causes lateral wall collapse but another philosophy is just do 10mm cause more is better. Not my philosophy but in most cases people are so deficient that the maximum is the same anyway. There's supposed to be a newer model that avoids some lateral wall collapse, I don't know what it is but I'm curious if anyone finds it.

maxilla was CW rotated? And the posterior extrusion of the mandible was to achieve CCW or what?

I don't think 7 mm is a lot, seems average advancement.-
