I realize now that the technique for avoiding the notch was described in 1990, the inferior border osteotomy. Most surgeons still don't perform it, I think it's just not worth their trouble for a small number of patients but I'm still suspicious there may be other reasons. This new modification is interesting but not a game changer I think. It removes some hardware at the expense of bony overlap. The mandible splits more easily but I think most of the damage is done by stretching rather than splitting.
