damn you had it bad! maybe just get a really good cosmetic surgeon to fix the aesthetic issue and account for the symmetry, via custom implants etc
Im not sure if the ccw movement of a bimax would cause further projection of the midface as the lefort 1 portion seperates the maxilla and repositions it, although im far from an expert. perhaps @lestat or @lazlo can chime in on the full aesthetic impact of the ccw rotation during bimax
Im not sure about the ramus, but you hypothesis seems plausible. its hard to say since it was so long ago, but the one thing i see for sure is that my midface has lost considerable projection 9 particularily the zygomatic body and inferior orbital rims) and since all 4 third molars were removed i can only imagine theres also been an impact on the mandible.
