Hi, wondered if learned members could offer any assistance. Got what appears to be cochlear hydrops in left ear 5-6 months ago. Deafness and tinnitus lasting 1-2 days but no vertigo. I posted a while back and problem now is attacks went from a couple weeks frequency, to 1 per week, now 3-5 per week, aka they are pretty much cycling continually. MRI/CT/Hearing tests all good...but my ENT is concerned the rapidity of these attacks will take a toll on my hearing shortly. All interventions so far have failed to slow it down. Strict low sodium diet, diuretics, serc, triptan( a migraine med) all useless. I was told next thing on the ladder is a "sac decompression" apparently 70% chance of success, 2% chance of deafness, some chance of relapse? Again I don't get vertigo so laby and gent perfusion not indicated and I haven't had hearing loss(yet...) so taking the plunge with this is a big deal. 1.Is this radical surgery? 2. Anyone had it or have stories to report? 3. I thought if it was that good more people would be doing it? 4. Any other last ditch meds I can try? I havent looked at herbs/supplements yet btw. About the only thing that stops the attacks is sometimes if they are just starting I do an intense cardio workoout, I have actually dampened a few attacks this way. Wondered if this sounds more migraine/vascular? Anyway, main thrust of the thread was the sac decompression, thanks for any thoughts on it.
