“…The quantity and quality of hearing rehabilitation is increasing from normal hearing aids, cross-and bicross-hearing-systems, bone conducted hearing aids, middle ear implants (MOI), cochlear implantation (CI), auditory brainstem implant (ABI) and auditory midbrain implant (AMI). After surgical removal of VSs, especially in neurofibromatosis type 2 patients, the supply with ABI is in most cases an option, but several studies showed an unsatisfactory outcome 8,11,13,14 . Especially the speech perception with an ABI in adults 15 , compared to the supply in young children 16 , is a huge breakdown.…”

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.

“…[1] It is impossible to estimate the average age of the patients in the studies, since most of them showed results involving patients older than 18 years old. Twelve (10.0%) of the patients had associated anatomic deformities, and 15 (12.5%) had other associated deficiencies or disabilities, as presented in Tables 1 and 2 [7,[10][11][12][13] . Among the studies, 13 patients [10,14] were fitted with the Pulsar CI100 ABI ® (Med-El Co., Innsbruck, Austria), 5 patients were fitted with a Concerto ABI ® (Med-El Co., Innsbruck, Austria) [10] , 1 patient received a Nucleus 22 Auditory Brainstem Implant System ® (Cochlear Co., Lane Cove, Australia) [15] , and the other 48 [7,13,14,[16][17][18][19] were fitted with the Nucleus 24 Auditory Brainstem Implant System ® (Cochlear Co., Lane Cove, Australia).…”

The Nucleus 24 and 21 ABI ® were activated using the spectral peak coding (SPEAK) strategy [7,13,14,[16][17][18][19] , and the Pulsar CI100 ABI ® was activated using the continuous interleaved sampling (CIS) technique [5] .…”

“…Regarding the surgical procedure, 4 patients [13] were fitted with ABIs with the retrolabyrinthine approach, 8 with the suboccipital approach [14] , 49 with the retrosigmoid approach, [10,18,21] and 2 with the translabyrinthine approach [1,3,6,7,9,[13][14][15][22][23][24] . Both patients with bilateral schwannomas and tumors caused by NF2 received the retrosigmoid and transmeatal combined approaches for tumor removal.…”

“…The time elapsed between the ABI surgery and initial stimulation of the cochlear nerve varied between 6 [6 ,22] , 8 [5,13] , and 10 [6] weeks in the selected studies. The activation was performed in an intensive care unit, with cardiac monitoring.…”

The objective of this study is to review the literature regarding Auditory Brainstem Implant (ABI) indications, surgical techniques, activation methods, and post-surgery follow-up in children. A search was performed in the LILACS, MEDLINE, SciELO, and PubMed databases in June 2014, and the key words used in the search were (("auditory brain stem implant" OR "auditory brainstem implants") OR ("auditory" AND "brainstem" AND ("implants" OR "implant")). Forty-two studies that met the criteria described in "Study Selection" were read in full; 24 studies referred to the ABI fitting process in children, and were selected for appraisal. The studies showed 120 children (younger than 18 years old) fitted with ABIs. Evaluation after surgery showed that 112 (93.3%) of the patients improved in their ability to recognize environmental sounds and speech perception. Patients with tumors or those with cochlear or cochlear nerve malformations had good outcomes as well. Two of the children did not achieve any sound perception upon ABI activation. The results obtained in 120 children fitted with an ABI showed that the patients globally improved in their ability to detect sounds and communication skills. The phenomenon could be seen both in patients with tumoral diseases of the inner ear and those with malformations of the cochlea or cochlear nerve, although patients with non-tumoral issues achieved better results than patients with schwannomas. We propose that the Food and Drug Administration (FDA) ABI indications should be extended to patients younger than 12 years old with NT diseases of the cochlea and cochlear nerve.
