title: [Clinical study on the ototoxicity of cisplatin with distortion products].
abstract: Distortion products are an objective method of hearing assessment that provides a rapid way to evaluate the functional status of the cochlea, so they are interesting for monitoring drug ototoxicity. We studied 50 ears from patients who received an ototoxic drug, cisplatin. Two consecutive measurements were made using distortion products 2f1-f2, before and after taking the ototoxic agent. We observed a significant reduction in the amplitudes of the DP-grams. At the same time, we evaluated the influence of previous sensorineural hearing loss on DP-grams, dividing the patients into two groups: normal hearing and sensorineural hearing loss. All these patients were evaluated at the same time by conventional audiometry in order to compare the effect of cisplatin on both tests. We conclude that cisplatin produced little effect on audiometric thresholds and an evident effect on the amplitude of distortion products.
