Implantable Hearing Aid: Report of the First Human Applications

Non-invasive optical synthetization of hearing sensation in non-genetically modified animal

“…Middle ear implants are commonly employed for patients with moderate to severe hearing deficiencies that cannot be adequately addressed with hearing aids ( 44 ). While middle ear implants can convey greater hair cell vibrations to the inner ear ( 45, 46 ), they necessitate surgical implantation with potential complications akin to cochlear implants ( 47 ). Our data demonstrate that the simultaneous presentation of auditory and laser stimulation produces a more pronounced neural and behavioral response than either stimulation alone (Fig.…”

The development of active middle ear implants: A historical perspective and clinical outcomes

“…The device was intended for adults with mixed hearing loss (MHL) who had BC thresholds between 20 to 40 dB SPL. The first patient implanted in 1984 reported good hearing, satisfaction, and sound quality . In the following years, 37 adults were implanted in the same clinic and demonstrated good hearing and speech perception in noise compared to optimally fit hearing aids .…”

“…The first patient implanted in 1984 reported good hearing, satisfaction, and sound quality. 17 In the following years, 37 adults were implanted in the same clinic and demonstrated good hearing and speech perception in noise compared to optimally fit hearing aids. [18][19][20] However, adverse events were reported in as many as 17 (45.9%).…”

Long‐term results with the Rion E‐type semi‐implantable hearing aid

“…The device was a partially implantable type in which a piezoelectric ceramic vibrator coupled to the stapes was activated by an electromagnetic induction system via transcutaneous transmission. Although some patients accepted the IHA enthusiastically because of the high quality of sound, [4][5][6] its manufacture ceased in 2005 because the company did not make sufficient profit, mainly due to governmental regulation of medical products in Japan. Experience with surgery and long-term follow-up studies of the patients prompted us to summarize the IHA project by analyzing device problems and postoperative difficulties leading to device removal or reimplantation.…”
