Study of the effects of chemotherapy on auditory function

Chemotherapeutic agents are known to cause multiple toxicities such as myelotoxicity, nephrotoxicity and ototoxicity. A prospective study was carried out on 60 patients receiving Cisplatin based chemotherapy in a tertiary care centre. The effects of Cisplatin on auditory function were studied using metabolic, biochemical and audiological parameters. The auditory effects were correlated with the dose and duration of chemotherapy. The study concluded that a significant percentage (15%) of patients who were subjected to chemotherapy based on Cisplatin developed high frequency sensorineural hearing loss which was permanent and irreversible in nature.
