      A Chinese Medical Report shows cutting cochlear nerve cured tinnitus.
      http://www.doc88.com/p-3993710989438.html
      The report is in Chinese, published ages ago, in the report, it states that two patients with severe T had significant relief after having the cochlear nerve cut, one was totally cured and the other one had huge reduction that T no longer bothered him.

      This link below reveals the similar results
      http://www.ncbi.nlm.nih.gov/pubmed/7671835
      It says one hundred fifty-one cases are reported. Complete relief of tinnitus was achieved in 101 patients, worthwhile improvement was obtained in 43 patients and 7 patients obtained no improvement.

      They both indicate that tinnitus must have something to do with our cochlear.

      I am not sure if any medical team has gone deeper than the results.

      The mechanism of T is now believed as being caused by deeper sections in brain instead of ear itself, based on MRI or some other imaging results showing the overactivity of several brain parts, but, say, when you scan an extremely suicidal person's brain, and if some parts are overactive, you can't end up with conclusion of these deeper brain parts are causing him suicidal, but in fact it works the other way around, the suicidal thoughts, in our case, T, or the emotion makes the brain overactive.

      I would be very happy to know that if the root cause is actually in cochlear instead of going deeper in brain, so you don't have to dig it too deep to fix it.

      Interesting....this disproves theory that tinnitus gets centralised the brain...as these guys must have been chromic suferers..looks like the CNS will revert to normal once auditory nerve is cut.

      So once you find a doctor all you need to do is sedate/numb the auditory nerve, you don't need to cut it! After sedating the nerve if your tinnitus stops then the origin of T is cochlear not brain and cutting the nerve would work.

      Yea, I would most definitely will want to have some tests done that can point to what us causing tinnitus before cutting anything.

      But... once you cut it, your hearing goes away,
      right?

      Yes, that is what happens as I understand it, you go deaf. It's a very drastic step to take quite frankly and I don't trust this study. As someone pointed out all that would be needed to test this theory is to numb that nerve temporarily. Regardless, cutting the nerve would be insane. Finding a way to "tame" it would be the goal for any serious medical expert.

      it doesnt make sense to me..
      if tinnitus appears once you lose some hearing,
      wouldnt this make tinnitus even fucking louder? lol

      This is why I believe the "brain filling in input gap" theory is wrong. As removing all the inputs doesn't make it catastrophically worse.

      oh.BTW. the reason I posted this is not encouraging people to go deaf but starting a discussion of where exactly is our T generated.

      If we figure that out, it can be a milestone of T research as when now it comes with the brain theory, all the research teams are pretty much like" oh, well..there is not much we can do at this stage. " And it can be a very misleading thing as well to detour us finding a treatment or cure.

      In one post,
      @noisebox said "I went to the dentist one time and had local anaesthetic on the T side for a filling. T went right down until it wore off."
      @RaZaH "Yep, same here"
      @AlexSongitus "This is exactly what happened with me when I did my AM-101 injections. Instant silence and relief by the time they vacuumed the Lidocaine out. I even asked the doctors, look if AM-101 doesn't work, can't I just come in for some sessions of Lidocaine and suctioning?"

      Apparently, dental local anesthetic does calm down T, which may explain that T may be in our cochlear which is close to mouth, because I don't think local anesthetic will reach that far to our deep brain.

      What do you guys think?

      Another point is that lots people can change there T by clenching/moving jaw. I would guess it is because cheek muscle is so close to cochlear which can physically change cochlear behavior, like making it more intense, etc.

      If the T signal is generated inside the brain, it would be harder to explain why physical clenching affect the activity in deep deep brain.
      That is why I personally support this "cochlear theory".

      Beat you to it :)

      It doesn't, because that Chinese thing isn't a study and the pubmed article does not dispute the actual facts. Moreover; you say centralized, and then name a pretty big general organ. There is no observable difference between chronic and acute tinnitus. And when there is no observable difference, there is no difference.

      I can publish a short study tomorrow stating that gravity doesn't exist but that doesn't disprove the theory of gravity. You have to take all work done in a certain context. Specifically you have to realize most of all science is shit, and more than half turns out to be untrue.

      The CNS can't return to normal after you've cut a part of it off, that's a bit like saying your tinnitus can be cured by going into a coma :)

      This really was already suggested for decades but it's kind of hard to properly study.

      https://www.tinnitustalk.com/threads/chapter-2-what-is-tinnitus.15681/

      The abstract reads; "Intractable subjective tinnitus originating within the cochlea or cochlear nerve can frequently be successfully treated by cochlear nerve section." so the study makes no claim about where tinnitus originates, in fact is clearly suggests it can originate in the cochlea or somewhere else.

      This is caused by the facial nerve (3) which interlinks with the auditory nerve and can thus pass on electrical charge.

      Tinnitus is generally very well if not completely understood or understandable. Much better than we see here on a daily basis. Study's about it can keep popping up but many of them have to be taken with a grain of salts. Especially when publicized by a single researcher.

      If a dental injection causes acute relief you can bet that the cause of it lies above the injection. If it does then I suggest you try LLLT in the ears.

      Noise - I think
      I've actually read articles hypothesizing that when input from the cochlea is lowered the gap is filled with electrical stimuli from surrounding nerves such as the facial nerve. And the hypothesis is that this is what is causing tinnitus. Wouldn't it then theoretically be possible to treat tinnitus surgically by insulating the cochlear nerve? I know it would probably be close to impossible to do in practice but at least in theory do you think it would be possible?

      That's interesting, good pointer. The facial nerve tinnitus connection is one of the things I want to test based on some papers that have come out on stimuli + sound. I'm on my way to the lab to check if I can replicate the ABR, my reasoning was that if I can test ABR I may use the same electrodes to stimulate the facial nerves.
      I'd also like to try confinement directed currents on those nerves and see if we can isolate one of them precisely.
      When I have some more time left I'll search for some articles on this, perhaps we can do some facial stimulus tests and record a change in the auditory potentials.

      I'll ask someone to slap me in the face and compare ABR's haha.

      @Cityjohn I can increase the volume (in the right ear) by clenching the jaw, yes, but also by simply tightening the platysma and the neck muscles, sans any imput to the jaw (In fact, I believe that the neck muscle contraction spill sover to the jaw/face and not the other way around - in my case). Also by full neck rotation in either direction (though moreso with full rotation to the left). And furthermore (and perhaps most confusing, or, telling, with regard to the facial nerve suggestion above), I can also increase the sound by simply sitting or lying perfectly still and motionless and putting pressure straight down on the top of my head (without ANY contraction of facial or neck muscles whatsoever). Do with this what you will, on those marvelous highways of your mind. (As for me, the facial nerve theory is compelling, has some validity, yet I wonder about other possibilities as well ... ).
