Supposedly something like 60% of people having cisplatin have some sort of hearing issue, in many it is a permanent loss of high-end hearing which cannot be corrected. In others it is a temporary ringing in the ears or feeling of "water in the ears" which gradually improves. A lot depends on dose and of course, individual sensitivity to the drug. However the side effect is common enough that my husband's MO would not use cisplatin on him, as he already has measurable high-end hearing loss (due to childhood ear infections) that interfers with his ornithological work. Instead she gave him carboplatin, which has a less than 3% chance of causing hearing loss.

Barry had a hearing test before treatment and again about 3 months after end of treatment and there had been no significant changes.

If you google "cisplatin and hearing loss" you can get more information with which to speak to your medical oncologist.
