Yes, exactly as I thought. I remember some girls talking about "not wanting a type 3", as if it was merely a procedure, instead of a forehead type that requires a certain procedure. Certainly, many of us also call the procedures used on the different types of foreheads "type #", but it is important to remember that the forehead dictates the technique that should be used, not vice versa, ESPECIALLY in type 3 cases. Perhaps type 1 foreheads could technically speaking be treated with an osteotomy (I don't know for certain), but it just seems wholly unnecessary, doesn't it. However, merely shaving the bone on type 3 foreheads (i.e. applying the technique used on Type 1 foreheads) is at best ineffective, and at worst potentially dangerous. Dr Suporn actually developed a technique that is proprietary and exclusive to him, where he resets the forehead in type 1 patients. From how I understand it, he shaves the bone and then, with a controlled fracture, "pushes" the forehead further back. He doesn't even mention type 2 on his page, so I'm assuming it's because he perhaps doesn't really treat foreheads with bone paste, and therefore lets the sinuses decide, so to speak. I can understand this, as I have been unimpressed with the alleged type 2 foreheads and treatments I have seen. It is a rather rare forehead type, though, because the entire idea behind type 2 is that your forehead projection is already within the normal female range, so it's very possible that I have seen results of women who weren't truly candidates for this procedure. Please read Dr O's book for more information.
Another area where you girls need to be mindful is the chin! Some surgeons only perform burring procedures, trying to shave down the chin, but you can only shave so much without causing damage, and if your face needs shortening (which most trans faces probably do), you need a sliding genioplasty. This is why it's so important to go to someone who specializes in bone work - they won't cut corners or have an incentive to sell you procedures that will ultimately underwhelm you.
