Is there anyway you can fight your insurance company? It isn't like this is some small situation. You do need the proceedure. Most of the time doing the whole thing is advised to my understanding. I would eat the cost rather than have this at all dangerous to your baby. I don't know what the risk would be to wait, but Bryanna will. A hole in the sinus does not sound like something I would want to wait on. I wish you all the best, a speedy resolution, and of course a healthy happy baby. ginnie
