Cochlear Implantation after Bromate Intoxication-Induced Bilateral Deafness: A Case Report

Hearing loss is a common consequence of the strong acidosis induced by bromate poisoning. Partial hearing recovery has been achieved through medical or rehabilitative therapy but reports of surgical otology treatment for this condition are rare. We report the case of a 48-year-old female patient who underwent cochlear implantation after bromate intoxication had induced bilateral deafness. In cases with life-threatening renal damage, the diagnosis of hearing loss is sometimes delayed, but in our case, hearing impairment was unavoidable despite early detection of symptoms and early disruption of the use of diuretics that could cause hearing damage. Hearing loss 12 hours after bromate ingestion was successfully reversed through cochlear implantation (CI) six months after completing acute phase treatment, including dialysis for acute kidney injury. The benefit of CI for deafness by bromate intoxication is highlighted by this case.
