I just saw a response to your original post (which I missed). May I
suggest reviewing the glycerine test which had been used for idenfication
of Menieres. Severl exchanges took place on this subject about 4-6
months ago on the ASHA aud form and/or Otolaryngology Lists. Although
I've not seen much recent notes about the test, my practical experience
had been positive that patients with Endolymphatic Hyd..showed improved
discrim/ pure tone/ symptoms with glycerine.
There is a Menieres organization on the internet you might be able to tap.
