Cochlear Implant – State of the Art

Cochlear implants are the treatment of choice for auditory rehabilitation of patients with sensory deafness. They restore the missing function of Thomas Lenarz 1 inner hair cells by transforming the acoustic signal into electrical stimuli in the majority of patients including the use of the telephone. Children can achieve a near to normal speech and language development provided their deafness is detected early after onset and implantation is performed quickly thereafter. The diagnostic procedure as well as the surgical technique have been standardized and can be adapted to the individual anatomical and physiological needs both in children and adults. Special cases such as cochlear obliteration might require special measures and re-implantation, which can be done in most cases in a straight forward way. Technology upgrades count for better performance. Future developments will focus on better electrode-nerve interfaces by improving electrode technology. An increased number of electrical contacts as well as the biological treatment with regeneration of the dendrites growing onto the electrode will increase the number of electrical channels. This will give room for improved speech coding strategies in order to create the bionic ear, i.e. to restore the process of natural hearing by means of technology. The robot-assisted surgery will allow for high precision surgery and reliable hearing preservation. Biological therapies will support the bionic ear. Methods are bio-hybrid electrodes, which are coded by stem cells transplanted into the inner ear to enhance auto-production of neurotrophins. Local drug delivery will focus on suppression of trauma reaction and local regeneration. Gene therapy by nanoparticles will hopefully lead to the preservation of residual hearing in patients being affected by genetic hearing loss. Overall the cochlear implant is a very powerful tool to rehabilitate patients with sensory deafness. More than 1 million of candidates in Germany today could benefit from this high technology auditory implant. Only 50,000 are implanted so far. In the future, the procedure can be done under local anesthesia, will be minimally invasive and straight forward. Hearing preservation will be routine.Keywords: cochlear implant, sensory deafness, diagnostics, surgical procedure, results, complications, future developments SummaryCochlear implants are electronical stimulus prostheses for the functional replacement of the inner ear. Because of the rapid technical development and the good results, they could be established as standard therapy for sensory deafness. Cochlear implantation requires an interdisciplinary team and a quality-controlled concepts that reaches from the indication to the life-long control and that is fixed in the AWMF guideline on cochlear implant [1]. Current cochlear implant systems are partially implantable and equipped with a multitude of additional functions similar to hearing aids for sound pre-processing and noise elimination. The intracochlear position of the electrode allows fo...

“…Damit kann unsere Untersuchung nicht nur die Ergebnisse vorangegangener Studien bestätigen, sondern unterstreicht auch die Geschwindigkeit der Hörrehabilitation bei älteren Patienten. Damit können die häufig in der klinischen Praxis gerade von älteren Patienten herangetragenen Bedenken einer möglicherweise langwierigen Hörrehabilitation entkräftet werden [11][12][13][14]26].…”

Zusammenfassung Hintergrund Tinnitus ist ein häufiges Begleitsymptom einer hochgradigen Hörminderung oder Ertaubung auch bei älteren Menschen. Die Hörrehabilitation dieser Patienten ist in der Regel nur noch mit einem Cochlea-Implantat (CI) möglich. In den letzten Jahren werden immer mehr ältere und sehr alte Patienten mit einem CI versorgt. Ziel dieser Studie war die Untersuchung des Einflusses der Hörrehabilitation mit einem CI auf die Tinnitus-Belastung älterer Menschen. Material und Methoden In diese prospektive Untersuchung wurden 34 Patienten zwischen dem 65. und 86. Lebensjahr eingeschlossen, die erstmalig unilateral mit einem CI versorgt wurden. 16 Patienten (47,1 %) hatten präoperativ einen Tinnitus. Zu je 3 Zeitpunkten (präoperativ, bei Erstanpassung und 6 Monate postoperativ) erfolgte bei den Patienten mit Tinnitus neben der Erfassung des Sprachverstehens die Erhebung der Tinnitus-Belastung mit dem Mini-Tinnitus-Fragebogen (Mini-TF12). Ergebnisse Sechs Monate postoperativ fanden wir eine hochsignifikante Verbesserung des Sprachverstehens von präoperativ 11,5 ± 17,4 auf 54,4 ± 28,1 % (p = 0,001), die von einer hochsignifikanten Reduktion der mit dem Mini-TF12-Fragebogen erfassten Tinnitus-Belastung von 6,9 ± 6,5 Punkten präoperativ auf 4,3 ± 3,3 Punkte nach 6 Monaten (p = 0,001) begleitet war. Schlussfolgerungen Die Hörrehabilitation mittels CI führt beim älteren Menschen zu einer hochsignifikanten Reduktion der subjektiven Belastung durch einen bereits präoperativ bestehenden Tinnitus.
