I do not know the success of the Lidocaine & Dexamethasone perfusion.....or the lack of success thereof. There is a surgeon in Atlanta that underwent a Lidocaine style treatment when I first noticed my T and was searching for answers. He was a very good source of what not to do and his opinion of the treatment that he received was that the situation was compounded. He did leave his practice as his hand was no longer steady and after a few years, we've lost touch some 15 years ago.
This procedure may be the same one quoted as having been in the works for 30 years or more.
I would only urge caution to anyone that allows desperation or a last hope "let's give it a try" mindset to over-ride common sense. I have always found my ENT to be a real naysayer about anything....but, that's why I go to him. I have no doubt when the solution, technique, therapy, procedure or little red capsule comes along...he'll be the first to call me and write the prescription or directive. Most ENTs are cranky as hell about Tinnitus because...they're helpless to do anything.
I have found a lot of little guy and gals in white coats that are willing to risk it all....correction, willing to risk YOUR all. I've had hyperbaric scams and last ditch noise riddance by an aural nerve sever that I never got that desperate which is a good thing.....I would have wound up like some of his patients.....deaf and still with the dentist drill in my right ear.
Folks.....times are financially tough all over the place. Tinnitus sufferers are a target market....and I would suspect that Tinnitustalk.com has it's fair share of sharks that are offering up hope. I am NOT saying that the author for this thread is a shark...but I've learned in my 15 years of hitting dead ends....I do NOT want to see the sales pitch for a procedure that allows...."100% covered by your insurance with the proper coding" (subject to your deductible) as one of the keys for a procedure that is not yet universally accepted.
The insurance angle is a big thing...but being able to function after laser drilling a hole through the tympanic membrane and then inject medications that such as lidocaine that has Tinnitus listed as a side effect. Or....the instant vertigo that accompanies such a intrusion that hopefully will clear up....but according to the disabled surgeon in Atlanta...that was not the case for him.
Caution and suspect should be uppermost in everyone's mind. Again...we're a huge target market with a 1001 snake oil salesmen looking just for YOU. They'll use the same charm of an unscrupulous Funeral Home salesperson to take advantage of your emotions and then unload a $20,000 casket on you while you're at your weakest morale.
It's only business....a bad, irksome, heinously selfish business...but the natural supplements that don't fall under FDA rules are all over the place with Tinnitus cures since I first got into this big boat. I do not know of the first person that started a regimen of the natural supplements to be cured of their Tinnitus.
If you're not sure...ask your ENT or personal physician to research their sources for the rate of successful treatment of anything. They'll be the first to wish you well and away from Tinnitus...and if it cures you and gets you out of a problem, you'll be the first to get good news and recommendation.
