Abstract
|
|
|
|
Electric acoustic stimulation (EAS) is the combination of acoustic stimulation via hearing aid and electric stimulation via cochlear implant in the implanted ear. EAS is indicated for patients with residual hearing at low frequencies and severe or profound hearing loss at high frequencies. These patients have no indication for conventional cochlear implant and have difficulties in adapting to individual sound amplification devices. Preservation of hearing is vital in this process and the surgical technique must be based on this concept. We report for the first time in Korea a case with EAS cochlear implantation, for which hearing preservation was successful and hearing results were excellent at postopertive 3 months.
