I'm confident that once doctors agree on the neurological pathway causing tinnitus they will be able to find ways to alleviate or fix this condition. The ATA needs a consesus about "The Cause". At this point, things are still in the democratic stage, where all ideas are equal. This is frustrating for us, because we want answers and we want them now.
I'm looking at a 2006 issue of "The Hearing Journal": Says that tinnitus researchers have been looking at the role of an organ called the dorsal cochlear nucleus (DCN). This organ is implicated in one of the oddities of tinnitus - somatically modulated tinnitus. TMJ and neck related tinnitus are "somatic" type tinnitus. With these types, a person can change the volume of the tinnitus by clenching their jaw, stroking their face or moving their neck:
"It therefore looks as though somatic modulation of tinnitus is a very common phenomenon, and the implication is that some neural pathway connecting somatic sensation with hearing is present in humans..the DCN is being suggested as a site where interaction between the somatic and auditory systems can take place."
So, there you go. Add "DCN" to the toolkit.
Whether it starts in the ear with inner hair damage, or at the DCN, I think the end defective neurological path is a feedback circuit in the central auditory processing system. I don't buy into theories about "irritated nerves", etc.
