It's important to note that Dr. Levine's studies theorize that there are really one of two scenarios where the DCN is compromised:
In either case, it seems likely that the somatic nature of the Tinnitus indicates that the problem isn't circulatory (and has an arterial blockage as the likely explaining factor here), but instead a question of cervical compression that can be best treated with re-alignment therapies and long-term physical work.
- Neuromuscular inflammation of the neck or head which causes nerves in the muscles that are spasming to interfere with the DCN's conduction and filtering process of auditory signals, generating tinnitus; OR,
- Neuromuscular conflict somewhere along the auditory pathway (also likely from a spasming or injured muscle group) erroneously activates the DCN and causes tinnitus.
I haven't read that the DCN can be compromised by simply "something in the brain." Separate studies have shown that when the brain is principally to blame, there is widespread malfunction of numerous centers, including those that are linked with emotion and memory, usually indicating some sort of auditory trauma as the genesis. Tinnitus caused by auditory trauma, however, does not ordinarily have a somatic component.
Therefore, one has to conclude that the etiological origin of your tinnitus rests principally on whether it responds definitively with somatic provocations and, more importantly, if it can be completely resolved through the use of powerful anti-inflammatories that suppress the somatic conflict to begin with.
I was able to get in touch with Dr. Robert Levine, the lead Dr. on the research, he sent me this PDF summarizing their efforts with this condition. His e-mail also had some links to Youtube videos, but I think they were more about general tinnitus. I can forward the e-mail if anyone wants it.

Hi everyone, glad I found this thread since what I have is very similar: pulsating T with heartbeat (95% of the time) that can be "turned" up or down by pushing on portions of my neck or turning my head. Most of the time my T can be turned down to almost off with large amounts of muscle relaxer (Robaxin) and general relaxants (like alcohol). However, on days that the T is high the relaxers don't do much at all.
I initially had a hearing test which came out fine. So they sent me to a dentist. After a CT scan showing my jaw too close to my skull they are treating it as a TMJ/TM Disorder (but without any pain) as a result of bad ortho plus grinding, which I am having various treatments:
- Splits since they believe I am grinding at night, plus put on a soft diet. Can't say I see any improvement from just this, but has been only two weeks.
- Massage therapy on neck. Definitely feels good and removes stress. Multiple knots removed and T seems to go down the evening after
- I had "trigger point injections" for the first time last week. Interesting result - when I turn my head to the right my T no longer goes up. I count this as an improvement. I go in for more injections tomorrow.
- I added a shrink to the mix and am on anti-depressants/talk therapy to deal with the initial panic from getting this. I will have to say I went from being in permanent panic mode to now more or less functioning normally, working, etc.
So as a summary the treatment is to prevent me from biting down (splits), work out all the knots in my neck and jaw with massage and injections, and thus allow for the TM joint inflammation go down and heal.
This is all theoretical, and some days I am hopeful (when T is way low - had a nice family dinner Tuesday where it was almost gone) and some days frustrated (up to screeching so loud last night that there was no pulsating). I will say there has been "improvement" in the last three weeks, but I can't say it is definitely going away.
I will give it six months and move to something else if I can't say there is definite improvement...

Okay had my second trigger point injections, going from the base of the back of my head down to the shoulder. He uses a topical freeze before the injection and uses lydocaine as the injection itself.
His theory is that the TMJ and grinding binds everything up, and just giving splints isn't enough. The muscles through the head neck and jaw are so bound up that they need additional support for the patient to "catch up" from all the spasmed and knotted muscles.
Most his patients have traditional TMJ pain and/or vertigo, and he admitted before we started that T alone was unusual for TMJ and is hard to chase down completely.
Now before I started this treatment I was running steady T up to a 7/10 (peaking even more), was able to get to 4/10 with muscle relaxers, and am now anywhere from 2/10 to 4/10 without relaxers (and even had a few hours of 1/10). My T is not gone but it has definitely gone in half in three weeks since I started splints plus trigger injections (plus massage therapy plus anti depressants I added on side).
So I'm hopeful that another month or two will push it down to a constant 1-2. I don't know if I can eliminate it, but can magage it if it stays there. After running 7 and panic peaking at 8 or 9, I really don't know how people manage, so my heart is out to those at those levels who have not been able to get relief.
I'll post on my progress and anyone feel free to drop me a an email with any questions.
