Are NT-3 and BDNF treatments that are currently available, or still being developed? All I'm saying, is if there is a surgery currently available, that has minimal negative side effects, it is certainly a huge positive. Other, possibly better treatments should continue to be researched, but for those who have been suffering for a long time, a minimally invasive surgery that on average boosts your LDL's by 10 to 20 dB is a godsend.
I know if my current situation does not improve I would gladly take an extra 15dB. I'd have *almost* normal hearing (certainly much more tolerable).
These NT-3 and the like have been around for a while. Before this research some ENTs could inject corticosteroids through the eardrum.
In my opinion, research is actually stalled. I mean, there are some papers coming out now and then, but no progress in decades. Also, the corticosteroid therapy through the eardrum does not really mean a significant improvement from just having corticosteroid pills with a glass of water. The benefits derived from corticosteroids are very limited, if any, and there may be side effects, immediate or in the long run.
So we are really talking about stuff that does not work, specially when it comes to a therapy that is not available for human use, like this NT-3.
Take into account that if there is an effective therapy for tinnitus or hyperacusis, and it means just injecting some drug through the eardrum, all hospitals are going to have it available, it would be on the news.
I think that the underlying causes of hyperacusis are more complex than most of us think, and maybe several areas of the hearing system are involved, including both the inner ear and the middle ear. The dynamic functioning of the middle ear muscles, seeing how they work in real time, maybe through scans or imaging (MRI) is poorly understood.
The general opinion of most ENTs about tinnitus or hyperacusis is that they cannot be cured, or that not much can be done to fix it. Maybe they can give advice but not much more. And there are no drugs to cure this.
So when I see research I am not that excited about promises of a future drug. Because these promises of an effective cure have been around for decades.
