A Case of Cochlear Implantation in Bromate-Induced Bilateral Sudden Deafness

ABSTRACT

Despite the well-established nature of bromate-induced ototoxicity, cochlear implantation after bromate intoxication has been rarely documented. We hereby present a case of a 51-year-old female deafened completely after bromate ingestion. Her hearing was not restored by systemic steroid treatment and hearing aids were of no use. A cochlear implantation was performed on her right ear 3 months after the bromate ingestion. In bromate intoxication cases, early monitoring of hearing level is necessary and other drugs with potential ototoxicity should be avoided. The outcome of cochlear implantation was excellent in this case of bromate-induced deafness.
