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.
