Tim, are you experiencing pressure, like your ears are plugged? I can't speak to the cisplatin related hearing loss, because I only had one cisplatin/docetaxol treatment (late in the radiation cycle; made me too sick to continue). I did, however, 'acquire' some hearing loss along with a plugged ears sensation after treatment ended. My ENT said the radiation caused a thickening of the eustachian tubes. She 'installed' tiny tubes through my eardrums in an effort to equalize the pressure. Did it help? Maybe a little, mostly not, but my hearing did improve. Is it permanent? Who knows.....
