Thanks for the detail...! I responded to you by PM with the specifics about the docs, etc... but for other people following thread, here is the redacted version of what I wrote:
It seems that DDM doesn't think that this sounds like DCS (especially given the time frame and the acute onset of symptoms on the surface with air pressure, etc.. Also, it looks like you did relatively short dives to relatively shallow depths on nitrox - that doesn't rule it out, and I'm not an expert, but I think that DCS is pretty unlikely. [DDM, am I over my pay grade here?]
Am I correct in assuming that you have no middle ear fluid, and that the tympanograms were normal? And that the hearing loss is a sensorineural hearing loss, not a conductive hearing loss?
The acute vertigo really does sound more like a fistula than other things, and if you do have a PLF you should NOT valsalva (or lift weights, dive or fly at this point, for that matter). Fistulas may heal spontaneously, but it doesn't sound like things are settling down. Don't know if they put you on stool softeners, but that's often done as well.
The bottom line is that there really is no test that will rule in or rule out a PLF ahead of time, it really is a surgical diagnosis. And you aren't risking much with the surgery if the person doing it is comfortable with ear procedures. It's just a middle ear exploration (where they lift up the eardrum), and look where the fluid might be pooling, and stick some fat or other material there if they see a leak. I really can't diagnose or treat anything over the Internet, but I think that if I was you I would certainly consider the operation.
I don't know these docs, but you could ask them about their otology training, if they had done this surgery before, and how many times and how recently... Like I said, the fact that they are practicing in paradise doesn't mean that they are not competent! If it doesn't sound like this is something that they really do, you could always come back to the US and go to an ear center.
Keep me posted...
