Lidocaine Injections to the Otic Ganglion (Nervus Trigeminus)

@attheedgeofscience recently mentioned that a doctor in Germany has completed a study with promising results where 300 patients with tinnitus have been treated with Lidocaine injections to the otic ganglion.

Unfortunately there is no further publicly information available about this study.

But if you do some research yourself you can find out that there is also a German source (publication by Eberhard Biesinger, a German ENT) where otic ganglion injections as a tinnitus treatment are discussed superficially.

The otic ganglion is a particular joint of the trigeminal nerve (nervus trigeminus). Clinical research in the US has shown that the trigeminal nerve plays a significant role in the development of tinnitus. Injections to the otic ganglion with 3 ml fluid which consists of 1% Procaine/Lidocaine are already a proven method to treat the following conditions:

• temporal-mandibular joint disorders
• disorders of the masticatory muscles
• diseases of the parotid gland (parotitis)
• neuralgia of the third division of the trigeminal nerve

Furthermore are such injections used in general to anesthetize the mandibular joint for various treatments.

I've never heard of Lidocaine injections to the otic ganglion as a possibility of treating tinnitus.
I will talk with my ENT about these injections and I think I will give it a try if he is willing to do it.

 

Thank you for this info. Considering my hyperacusis came on with facial neuralgia (I was diagnosed with trigeminal neuralgia initially), I have TMJ disorder and tinnitus, I think this could be a real possibility for me.

 

I had an appointment with my ENT an hour ago and talked with him about Lidocaine injections to the otic ganglion.

His response (summarized):

Injections to the otic ganglion are too risky. If you stitch with the needle just a bit besides the otic ganglion you damage other nerves and can cause a permanent sensory disorder. One can train this kind of injection but you won't find an ENT in this town (1 million citizens, more than 80 ENTs) who is willing to do it.

He's an assistant medical director of the ENT station at a renowned hospital here.

@attheedgeofscience, you state that a doctor in Germany did these injections to 300 patients.

Do you have any further information regarding the risks or do you know why this doctor incurred such a risk in case of 300 patients? I really want to try this, but my ENT sounded like it's a lottery win to hit the otic ganglion with a needle.

 

This study reviewed tinnitus patients suffering from somatosensory tinnitus. They were treated with Lidocaine injections to the Otic Ganglion.

 

Lidocaine injections to the otic ganglion for the treatment of tinnitus - A pilot study

"We did not observe any relevant side effects. There was a significant reduction of tinnitus distress (Mini-TQ, Tinnitus severity) and loudness (measured subjectively) over time. Our pilot data suggests that lidocaine injections targeting trigeminal structures may be able to reduce tinnitus complaints. Future studies should investigate the effects of lidocaine injections in placebo-controlled trials in an extended sample size to further explore the potential benefits of this therapeutic approach on tinnitus."​

I'm getting to the point where I might have to beg a dentist to do this.

 

There's nothing new about this in 5 years?

 

I recently spoke to someone who got rid of her tinnitus by getting these Lidocaine injections. But I have to mention this person also did many exercises the doctors advised her to do in order to really get rid of her somatosensory tinnitus. After all of this she is now tinnitus free and Biesinger wants to take a deeper look into tinnitus patients receiving this injection but also doing the exercises. But this injection really is only helpful if you have a somatosensory tinnitus, otherwise it’s useless.

 

How can one be sure they have somatic T or not? So many doctors are clueless about T how can one be sure?

 

Like everything with tinnitus it is subjective, but if you can modulate your tinnitus my moving pulling twisting or extending your face or neck it is somatic tinnitus. For example, if I open my mouth wide, clench my jaw, or pull back in my scalp the pitch and quality of the noise changes.

 

The more I research/speak to different health care "fields" the more I'm convinced the Vagus nerve has a great deal to do with tinnitus (Vagal tone). Forward head posture (cervical kyphosis) should be at least investigated by all those impacted; especially C1 and 2 where the VN makes its way into the coconut.

 

When I open my jaw really wide or bend over, I hear additional sounds rather than current ones changing.

 

Same.

 

I think that is completely normal. I have noticed the same even before I had tinnitus or even knew about it.

 

I can modulate some of my noise, but after inducing residual inhibition with sound files, I can still hear head noise.

What's going on there?
