My Dad has been referred to Seattle or Salt Lake area after having sinus surgery and having tumors and a number of Polyps removed. Apparently the Tumors are bone eating and have deteriorated much of the bone in his forehead, around one eye and the side of his nose. The referring surgeon said it is serious and much too complicated for him to do. We are not limited to location, it would be most important that we get the best doctor in hopes of him not going blind in both eyes after surgery.
