Poor Performance with a Cochlear Implant: A Case of Overinsertions
JD is a 13-year-old girl who transferred care to our cochlear implant clinic following a move from out of state. She was diagnosed with a profound hearing loss of unknown etiology following a failed newborn screening at birth. At 12 months of age, her right ear was implanted with an Advanced Bionics device. She experienced significant facial nerve stimulation when using the device and failed to make progress despite regular participation in auditory verbal therapy (AVT). When she was 29 months of age, the device was explanted and replaced with a Nucleus CI24RCS device, but she continued to demonstrate poorer than expected results. At 36 months of age, her left ear was implanted with a Nucleus CI24RE device. JD preferred the sound quality of her left ear, and she continued to report inconsistent sound quality in the right ear despite participation in regular mapping appointments. She continued to receive weekly AVT services.
