I had ballon dilation and while it worked for about two weeks and I believe my tinnitus was gone at that point my ears became clogged again because I still have mucous production from who knows what, so I am still working with supposedly the top ENT in the region see him again tomorrow I don't know if there is any way to tell if your Eustachian tubes are blocked other that the feeling I have in my ears let you know how things turn out.
