Melissa, if the sinus cavity is small, the results of shaving the bossing is basically the same as reconstructing the forehead, except the nose bridge is usually higher because the orbit is not completely shaved down(Which is better in most case, since you'd remove most ressemblance to a member of your family (male or female) if you remove to much of the orbit). When the sinus is bigger and in a more frontal position, the orbit needs to be shaved down and the forehead reset back.
In my case, Brassard shaved the forehead to very slightly above the base of the nose (he said he could have gone further), to leave the glabella, which is seen as esthetically superior than a smooth nose to forehead transition.
A higher bridge is also seen as esthetically superior in rhinoplasty, check the rhino boards. That's what most models have. If you can avoid having to have a low nose bridge because they reset your forehead, that's the way to go.
