David,

Not sure what you mean when you say hair cells in both ears? After my 2nd dose of cisplat I had ringing in my ears and I felt like I had a bag over my head. I had a hearing test which showed some damage and my MO and I decided to switch to carboplat for my last chemo treatment. I do have some damage but am hoping that it is only temporary, I don't have the ringing as much and when I can get my ears to pop I can hear better.
