 About one-third of people who have been given Cisplatin, as part of their chemotherapy treatment, develop hearing loss. The purpose of this study is to determine if some degree of hearing loss can be prevented by use of Lactated Ringers solution in the middle ear. To study this, patients will use drops in their ears; Lactated Ringers will be placed in one ear and an inactive saline solution will be placed in the other. Ofloxacin, an eardrop antibiotic will be placed in each ear at the same time. Each participant will receive a hearing evaluation before each dose of Cisplatin and another evaluation 2 to 4 weeks after the final treatment.
