Sleep Apnea Treatment

I have chronic sinusitis caused by a deviated septum resulting from damaged to my head and face sustained in an Army helicopter crash. Shortly after the crash, I developed the sinus infection and while I had most, if not all, of the symptoms associated with sleep apnea, it was not diagnosed until much later. I have had one operation on my nose which did not solve the problem and I ABSOLUTELY will not have another. The Veterans Administration has denied service connection for my sleep apnea and I need some authoritative source to support the assertions found on dozens of ENT and Apnea sites, which cite chronic sinusitis as a cause ( one several possibilities) for sleep apnea. Thanks, Wavie
