BTW, fluid causes a conductive loss. NO CONDUCTIVE LOSS ALONE CAN CAUSE A PROFOUND HEARING LOSS.
So because of this, we already know that the cochlea has been damaged. How, we don't know. As the musicman suggested, the round window may have ruptured. The window in many cases heals on its own... but the damage done to the cochlea is USUALLY permanent.
Again, I wish you luck
Your ENT probably can not read an audio gram to save his/her life. So sad, so very sad, and they are the ones that are supposed to have supervisory authority over audiologists!
Your doctor is retarded. That very well could have been flued from your cochlea that he drained out of your middle ear. You need are real ENT... that I wish you luck in doing so. I tell you, it is a pleasure not to work in a country were people on now ran through the door like cattle!
I imagine you,ve had this dealt with by now ... if not
it sounds like inner ear barotrauma possibly blown window but generally this would present with
extreme vertigo.Probably just cochlear damage of some lesser degree.
If your hearing still hasnt improved try an injection called an intratympanic injection of steroid
through the eardrum . Its the most powerful way to get a result and typically can have positive effects until 6 weeks out from injury but it has been tried later with limited results.
Don't delay if your ENT doesnt do it find a neuro-otologist at a university health centre close by you.
Good Luck.
