Please, if at all possible, keep us posted on your treatments and findings. I know some drs can actually place a scope into your nose right the the eustachian tube to view it. But if you go the MRI route, I'd love to know more about that. I'm seeing an otologist at MUSC (specialist) myself coming up who thinks a ballon dilation might be helpful for eustachian tube dysfunction, but no one has ever definitively diagnosed it, or actually looked AT my eustachian tubes. I have the fullness though, the pressure, and a layer of high end hearing comes back when I do Toynbee manoever (I stopped doing valasalva a few months ago). I actually try to do toynbee as few times as possible, but the pressure/fullness feeling is maddening. I really want to compare notes if we can - so again, please keep us posted and good luck with all of this!!!
