The low frequency drops are strange. That is probably why your doctor was thinking hydrops, but low frequency losses don't always mean such a phenomenon is occurring. Also, you must be lucky they went down to 125 hz; that's a good reference. The high frequencies look good for your age though.
Did they test for bone conduction as opposed to air conduction (it does not look like they did)? Sometimes low losses are conductive in nature (and I'm not talking about fluid in the ears).
I really don't know what it means, especially if you do not get a roaring tinnitus. Did you expose yourself to a lot of bass music while clubbing over the years? That will do that kind of damage in the lows.

Fluctuating tinnitus has been linked to tinnitus to Hydrops, but they have never been able to see it. If they could see it on an fmri that would be huge! I am guessing that is probably the part that got mixed up, unfortunately. Boy, I wish they could see it.
No. Actually, all of the Neurotologists I have been to said that the ECOG is basically useless.I thought they could already "see" it with an ECOG...
I think that they mean getting louder and then much quieter or stopping completely for a period of time.By fluctuating, do they mean on-and-off, or always present, but rising and falling in intensity as in changeable within the passing seconds. Mine consists of a background roar that is just there as a constant, but with a secondary sound that seems to spurt and hiss constantly, always rising and falling (which I guess is why TRT is useless, as the tinnitus reminds me minute to minute that its there).
