I think it's just that the ENTs don't have a whole lot of options when it comes to those of us who have allergy-triggered sinus issues that fail to respond to antibiotics. I've seen three ENTs in nine years. The last one I saw is regarded as the best in our area. He actually apologized to me b/c there was nothing he could do for me that my allergist wasn't already doing. My CT scans always indicate nothing beyond inflammation. Xrays the same way. THank God the Xolair that I've been taking for my allergic asthma has also helped with rhinitis.
