A reader asks:Â
I have been dealing with terrible almost constant vertigo due to Meniere’s Disease for 10 years. In that time, I have been through three procedures for my left ear: (1) intratympanic (IT) gentamicin which knocked out all hearing and made more worse, then (2) a transmastoid labyrinthectomy which did nothing, and then (3) a translabyrinthine vestibular nerve section, to no avai. Now I have symptoms in my right ear and I was diagnosed with bilateral Meniere’s Disease. Doctors now give me two choices: right endolymphatic sac shunt/decompression/amputation or titrated intramuscular (IM) streptomycin. I am inclined take the streptomycin, although I am aware of the possibility of occillopsia and the likely resulting ataxia, but to get rid of the constant dizziness it might be worth it. I am very scared about bilateral loss of vestibular function and have seen much literature that suggests low-dose streptomycin that blunts rather than completely ablates vestibular function can avoid the worst of the side effects. What would the most reasonable option seem to be? I really don’t want to go through another mastoidectomy and endolymphatic surgery if I’m going to end up going through IM streptomycin anyway.
IM (intramuscular) streptomycin means that the drug is administered “systemically” by injection into one’s muscles, meaning that it will affect the whole body, the whole system, including both ears. To affect just one ear, it would be administered IT (intratympanically) (through the eardrum). In your case, there is little significance because you have already had a surgical labyrinthectomyin one ear, which removed and therefore destroyed all hearing and balance in that ear. However, IM streptomycin will damage or destroy whatever hearing you might have remaining in your right ear. If you have any remaining hearing at all, and you want to keep it, you would want to avoid streptomycin. Unless our doctors and authoritative studies convinced me otherwise, we would consider IM streptomycin to be absolutely destructive; we wouldn’t put any faith in a particular outcome for “low-dose” streptomycin. But you have seen “much” literature to the contrary, so let your own research be your guide.
No doubt you are skeptical of IT gentamicin from your previous experience with your left ear, but if you have remaining hearing, it might be worthwhile to consider “low-dose” IT gentamicin.
However, if we understand your email correctly, you have had chemical ablation of your left inner ear by gentamicin, a surgical labyrinthectomy, AND a VNS in your left ear, and none of these treatments gave you any relief. What a horror story! No doubt you are concerned for the possible same outcome in your right ear.
To us, who are not doctors, your analysis seems reasonable, and the IM streptomycin would be an easier ride than another endolymphatic surgery.
But we think that the better course of action is to get additional medical opinions, as we always recommend. That’s what we would do if we were in your shoes. That would be a lot better than any information that we could provide.
We hope that whatever you do, the results are better than what you experienced on your left ear.
We sure do feel for you.
