sudden hearing loss

Posted By bill on October 08, 1998 at 18:55:07:








I had sudden complete hearing loss three weeks ago. For the first three days I also had severe vertigo, which occurred about three hours after the sudden deafness. MRI and CT scan showed my brain and inner ear are normal.
The ENT doc said most likely the blood vessel in my inner ear suddenly died, like a stroke. I am very healthy  
before the hearing loss.  
My first question is what should I do to prevent this happen again in my other ear? How to prevent a stroke ?
My second question : is it possible to revive the hair cell now, three weeks after the onset of the illness?
Thank you for your kind reply!
