I have sinus issues and OSA. As annoying as my sinus problem can be, it has not been affected one way or the other with my OSA treatment. I used to snore like an Apache helicopter attack, and was diagnosed with severe sleep apnea. The dentist knows of my sinus problems, but prescribed a proprietary hybrid oral appliance. At night when all my muscles relax, my tongue would also relax and physically block my airway. The oral appliance has an arch across the back (the open end) which my tongue rested against at night and stayed out of my throat. Simple. Snoring stopped immediately and a post sleep study proved my OSA is being successfully treated. In the seven years wearing this device (at night, haha) I do not know of anybody who has not been successfuylly treated with this appliance. Keep the tongue out of your throat and it solved my problem.
