We performed a cochlear implantation for a deafened 2 year old girl with ossified cochleae after meningitis. Ten electrodes were partially inserted using the Nucleus 22, but her hearing did not improve. One year later, re-implantation was performed using a total cochleostomy with the Nucleus 24M. She did not feel any sensation from electrical stimulation and did not display an NRT response.
She wore a cochlear implant and a hearing aid in both ears without a hearing response. After 12months, she responded to her name. After 2 years, her hearing level was at 30 dBHL. We concluded that continuous electrical stimulation was effective in improving her hearing.
