I have a 2 1/2 year old son w/CF that has severe sinus problems. He has been on antibiotic since he was 1. As soon as he stops taking it, his sinuses get packed with mucous and infection. We use a saline irrigation and Rhinocort everyday twice a day. He has (and is currently) using the Sinuneb system - an antibiotic and an anti-inflammatory mist inhalant. He has also had 2 sinus surgeries to clear everything out. That only kept him clear 6 DAYS. The ENT was expecting 1-3 years. Nothing has worked except continual antibiotic treatments. Has anyone else had these same problems? What have you tried? What has worked to keep your sinuses clear? The Sinuneb system has worked for us in the past, but it is very hard to get a 2 1/2 year old to sit still for an hours worth of treatments. It is also very expensive and come June 1st, my insurance may no longer cover it. Any help or advice is greatly appreciated.Thank You ~ Dina
