As stated above, I had this procedure performed on one of my ears at Shea Clinic. The procedure itself is uneventful. After the drop of phenol on the ear drum you feel nothing. When the drop hits the ear drum it stings for 5-10 seconds or so and the Dr waits a few moments and then suctions off the excess phenol and wax/debris from on top of the ear drum. After about one minute the Dr takes a small instrument (laser) and makes a very small hole in the ear drum while watching on a large flat panel (30") display monitor that is being fed by a Leica stereo scope with video CCD attachment. The laser perforation of the tympanic membrane takes 1 second and then the nurse hands the Dr a 20 gage syringe with the mixture of dexamethosone and lidocaine. The Dr then tells you that a sensation of cold in the inner ear will happen upon injection of the mixture. As he begins the injection your vestibular system reacts to the cold temperature of the mixture and you get vertigo fairly quickly and it slowly subsides. The Dr asks if your ok....and if your hearing is ok. You are then taken to recovery and the dex/lido IV is started for 2 hours. As the IV is in place you feel a sensation of slight numbness throughout your body and the ringing in your ear diminishes measurably. This procedure is repeated (3) times over a 3 day period. On day 3 my tinnitus was almost 100% gone. I had go in the bathroom in complete silence to hear it. I stayed at the Residence Inn (owned by the Shea family trust) and each day I used the breezeway that connects to the clinic to make my trek to the 3rd floor out patient surgical center.
Does the procedure work? The answer is......"it depends". For me it turned my T into a shhhhhhhh sound from a EEEEEEEEE sound. And cut the volume in half. Since my insurance paid for the entire procedure 100% and I obtained a measure of improvement I am pleased and I would say it worked for me. It did NOT cure my T but it is the only procedure that has worked to reduce it at all and it easily cut the volume by 50%.
I have read comments on this site stating that if the Shea procedure was so great that many people would be getting the procedure.....well, after a visit to the Shea clinic it doesn't take long to see that the magnitude of the Shea operation is quite large in scale and many people (each day) have this procedure (perfusion). Some people have the procedure every 3-4 years and respond quite well to it.
During my 4 days at the Shea Clinic I had the occasion to speak with at least 10 separate perfusion patients during the free "social hour" at the Residence Inn dining room each evening where patients were comparing notes and talking about their ear problems. About half the people going through the perfusion treatment have tinnitus and balance issues (Menaries or hydrops).....and the others have just tinnitus. In each group there are positive and negative responders to the treatment protocol.
Perfusion effectiveness for tinnitus is probably a 50/50 situation for any given person. Tinnitus, while everyone wants to cloak it as some mysterious malady, is really quite simple to explain.....the hearing nerve becomes damaged (90%+ caused by aggregate exposure to to high sPL) and as the higher frequencies of the hearing range are lost tinnitus becomes noticeable as the range drops below 8000. To achieve deep silence in the auditory system the hearing nerve uses certain portions of the high frequency range to inhibit and maintain a "deep silence". Once this inhibitory function is lost tinnitus is perceived.
The perfusion process works by flooding the cochlea with a powerful corticosteroid through the round window membrane that (if it can reach the lesion) may be able to repair or lessen the damage. The lidocaine shuts down abbherent neuron function and allows for an opportunity to reset the auditory communication path ways should the dexamethosone have a positive effect on the targeted lesion.
In cases where dexamethosone reaches the lesion in the early stages of tinnitus it is very effective at ameliorating the malady. As time passes the lesion becomes more permanent and less receptive to repair/reversal.
There are also cases where the perfusate chemical concentration levels at the lesion site can be not be achieved for various reasons and mixed perfusion treatment results are achieved.
My particular perfusion treatment protocol reduced the volume of my tinnitus by an estimated 50% and changed the sound type to a more tolerated sound.
There is really no other known treatment protocol that offers any probable impact on tinnitus. None!
All other treatment modalities only play off an individuals ability to habituate to the tinnitus over time. Example; some people go out and get Soundcure or Neuromonics and report great results while others report it does nothing?
If a person perceives some relief while on sound therapy it is more probable that they reached some level of habituation during the sound therapy treatment than the sound therapy actually having an impact on the tinnitus.
The same for TRT and various drug protocols.
The perfusion treatment is not well aligned with a habituation curve in that it either works or does not and you have a direct correlation to its effectiveness, or lack thereof....very quickly.
The price of the procedure is $8400 for the three day protocol. If your insurance deductible is met the cost can be zero. Your insurance has no say if the procedure is covered or not. It's a standard CPT billing code of 69801 and simply means "delivery of medications and/or steroids to the inner ear". This CPT code does not require a pre authorization. Shea accepts the insurance pay rate for 69801 as payment in full.
Feel free to ask me any questions you wish regarding this procedure.
