There was nothing to it at all. Surgery, including complete sinus flush lasted 15 minutes, the next day you would have never known he had anything done to him. You will just tripple meds day of surgery, and they will give him an IV does of cortef and then he is no different than any other patient. It is the best thing we ever could have done. ANd we too fretted and worried beforehand, but wow, was it ever worth it!
