“…Improvement of the loudness, frequency and intensity of the tinnitus was expressed by 50% of the patients and the ability to conceal the tinnitus was emphasized -supporting previous findings 32 . Never the less, this percentage is under the expected improvement in unilaterally implanted deaf people without vestibular schwannoma operation 33 .…”

Objective: With rising quality of speech perception in cochlear implant users, the indication widens. Nowadays, cochlear implantation is reasonable even in vestibular schwannoma patients. Speech perception with a cochlear implant is in these patients as promising as in patients with sensorineural hearing loss. However, the impact of cochlear implantation on vertigo and tinnitus after removal of vestibular schwannoma has not been investigated yet. Methods: In a retrospective study, we analysed 12 patients treated with a cochlear implant after removal of vestibular schwannoma. Results: In addition to a promising hearing perception -all patients reported improvement of vertigo. This improvement was also demonstrated by postural analysis. Improvement of tinnitus was achieved in 50% of the patients. Conclusion: Cochlear implantation seems a promising treatment for hearing loss, vertigo and even tinnitus in patients after removal of vestibular schwannoma. However, for successful cochlear implantation with adequate speech perception and improvement of vertigo and tinnitus, functional hearing nerve and intact inner ear anatomy is necessary.

“…The use of additional tinnitus suppression is possible [10], [11]. The preservation of the residual hearing ability in the context of high-frequency hearing loss allows the use of electroacoustic stimulation.…”

“…In cases of unilateral deafness, the cochlear implant may lead to a significant improvement of speech understanding in noise as well as directional hearing and tinnitus suppression. Early implantation in children may induce the development of binaural hearing [10], [11]. However, the hearing results of the implanted ear are poorer than of the normally hearing ear of the contralateral side.…”

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...

“…Although the first studies of unilateral CI implantation, dating back to 1957, were in patients with bilateral deafness [23][24][25], CI for SSD began fortuitously in the 2000s as an experimental treatment for incapacitating and intractable tinnitus [26] when users reported marked gains in sound localization and speech perception in complex listening environments [7]. Because hearing loss co-exists in up to 85 % of individuals with tinnitus [27], hearing improvements were likewise reported in subsequent studies of CI in tinnitus patients with ipsilateral SSD [9,10,28]. The small number of studies that directly compare benefits with CI versus Baha or CROS strongly endorse CI over these more rudimentary treatment strategies [10,29].…”

Cochlear Implants in Single-Sided Deafness

Single-sided deafness presents a unique challenge to otolaryngologists and audiologists. While the normal hearing ear may allow listeners to perform adequately on audiometric screening, individuals with only one functioning cochlea suffer when resolving speech in noisy environments and in sound localization-which both contribute to a reduced quality of life. Though there are a variety of strategies that provide contralateral routing of sound signals, the cochlear implant is the only treatment to truly restore binaural hearing. Only very recently has cochlear implantation (CI) for singlesided deafness begun in earnest, with encouraging results that demonstrate the strengths and pitfalls of implantation over traditional extracochlear methods. The purpose of this review is to update the field by emphasizing binaural benefits, discussing historical treatments of single-sided deafness, critically evaluating recent data on outcomes of CI for single-sided deafness, and recommending indications for cochlear implants in single-sided deafness in children, adults, and subjects with concurrent ipsilateral tinnitus.
