I have no idea if it will work for your case or not but if you can try it out at a store (many will fit you with things) there are nose models that both go underneath ("pillows") as well as that go over the nose kindof like a full face mask. But then the one I'm currently using is the ResMed F30i whic his a full face mask but doesn't go up over my nose so it's not as.. face enclosing.. which is why I like it. But the entire thing is like a bouncy silicon which seems to put less pressure on my face than some of the other full face ones I tried so may be worth a try.
