“…Speech perception results were better the longer cochlear implants were used, even though there were no statistically significant differences in duration of cochlear implant use and open and closed set speech recognition. Other authors have also pointed out a gradual development of speech perception abilities following cochlear implants use for some time in different groups of children [25][26][27][28][29][30][31][32][33] . The mechanism by which OAE deteriorate or are lost in AN/AD patients remains unknown; no significant relationship between absence and/or possible loss of OAE and any specific changes in AN/AD were found.…”

The electrical stimulation generated by the Cochlear Implant (CI) may improve the neural synchrony and hence contribute to the development of auditory skills in patients with Auditory Neuropathy / Auditory Dyssynchrony (AN/AD). Aim Prospective cohort cross-sectional study to evaluate the auditory performance and the characteristics of the electrically evoked compound action potential (ECAP) in 18 children with AN/AD and cochlear implants. Material and methods The auditory perception was evaluated by sound field thresholds and speech perception tests. To evaluate ECAP's characteristics, the threshold and amplitude of neural response were evaluated at 80Hz and 35Hz. Results No significant statistical difference was found concerning the development of auditory skills. The ECAP's characteristics differences at 80 and 35Hz stimulation rate were also not statistically significant. Conclusion The CI was seen as an efficient resource to develop auditory skills in 94% of the AN/ AD patients studied. The auditory perception benefits and the possibility to measure ECAP showed that the electrical stimulation could compensate for the neural dyssynchrony caused by the AN/AD. However, a unique clinical procedure cannot be proposed at this point. Therefore, a careful and complete evaluation of each AN/AD patient before recommending a Cochlear Implant is advised.

“…Studies on cochlear implants in postlingual deaf patients also show an influence of the duration of deafness on functional outcome, especially speech perception: Oh et al 44 report 5 years of deafness as critical, whereas Durisin et al 12 found significant differences when comparing scores from before and after 6 months of deafness; also, over long training periods patients could not catch up in speech recognition. Peasgood and colleagues 50 found no speech recognition in adults with late cochlear implants, and much less favorable results than are associated with cochlear implants in general.…”

“…Most authors discuss periods of a few years to more than 10 years, and advocate ABI surgery before 10 years of deafness. 3 Corresponding to experiences with cochlear implants, 12,44 durations of a few years must be considered and might decide whether there will be any hearing sensation at all. High-quality hearing, however, is dependent on much shorter periods.…”

Object Patients with bilateral auditory nerve destruction may perceive some auditory input with auditory brainstem implants (ABIs). Despite technological developments and trials in new stimulation sites, hearing is very variable and of limited quality. The goal of this study was to identify advantageous and critical factors that influence the quality of auditory function, especially speech perception. Methods The authors conducted a prospective study on ABI operations performed with the aid of multimodality neuromonitoring between 2005 and 2009 in 18 patients with neurofibromatosis Type 2. Outcome was evaluated by testing word recognition (monotrochee-polysyllabic word test at auditory-only mode [MTPa]) and open speech perception (Hochmair-Schulz-Moser [HSM] sentence test), both in pure auditory mode. The primary outcome was the HSM score at 24 months. The predictive meaning of general clinical data, tumor volume, number of active electrodes, duration of deafness, and early hearing data was examined. Results In 16 successful ABI activations the average score for MTPa was 89% (SD 13%), and for HSM it was 41% (SD 32%) at 24 months. There were 2 nonresponders, 1 after radiosurgery and the other in an anatomical variant. Direct facial nerve reconstruction during the same surgery was followed by successful nerve recovery in 2 patients, with a simultaneous very good HSM result. Patients' age, tumor extension, and tumor volume were not negative predictors. There was an inverse relationship between HSM scores and deafness duration; 50% or higher HSM scores were found only in patients with ipsilateral deafness duration up to 24 months. The higher the deafness sum of both sides, the less likely that any HSM score will be achieved (p = 0.034). In patients with total deafness duration of less than 240 months, higher numbers of active electrodes were significantly associated with better outcomes. The strongest cross-correlation was identified between early MTPa score at 3 months and 24-month HSM outcome. Conclusions This study documents that open-set speech recognition in pure auditory mode is feasible in patients with ABIs. Large tumor volumes do not prevent good outcome. Positive preconditions are short ipsilateral and short bilateral deafness periods and high number of auditory electrodes. Early ability in pure auditory word recognition tests indicates long-term capability of open speech perception.

O desenvolvimento da percepção de fala e aquisição de linguagem, bem como, o sucesso da reabilitação auditiva depende de alguns fatores determinantes como: tempo de privação auditiva, etiologia, engajamento do paciente e da família, entre outros.A reabilitação no implante coclear tem início na ativação dos eletrodos e na realização do mapeamento. Não difere da reabilitação do deficiente auditivo adaptado ao aparelho de amplificação sonora.Todos os pacientes, independente da época de instalação da deficiência auditiva, dependem para que seus resultados sejam positivos da eficácia do treinamento auditivo formal e do engajamento nas atividades orientadas.O Implante Coclear é uma alternativa para os pacientes com Deficiência Auditiva profunda. Esse recurso pode permitir grande mudança da qualidade de vida desses indivíduos aumentando a independência, motivação e melhorando o relacionamento social.Descritores: Implantes Cocleares. Audição. Percepção de Fala. 273 1-INTRODUÇÃO Deficiência AuditivaA Deficiência Auditiva (DA) exerce importante impacto sobre a comunidade, seja do ponto de vista econômico, envolvendo altos custos na sua detecção e reabilitação, seja do ponto de vista psicossocial, não apenas para o indivíduo, como para sua famí-lia e sociedade. 1,2 Depois de detectada a DA convém agilidade no início da reabilitação auditiva, visto que temos perío-dos de prontidão para o aprendizado e fatores, como privação auditiva, que podem interferir no processo de reabilitação.Bebês com perdas auditivas, particularmente os portadores das neurossensoriais, podem ter o desenvolvimento das vias neurais auditivas prejudicado, comprometendo diretamente a aquisição normal da linguagem. 2,3,4 Avanços recentes na neurociência cognitiva demonstraram na plasticidade do sistema nervoso central, a existência de períodos críticos e a possibilidade de fortalecimento das ligações sinápticas pós experienciação nestes períodos. Tanto a plasticidade quanto a maturação é, em parte, dependente da estimulação Medicina, Ribeirão Preto, Simpósio: SURDEZ: IMPLICAÇÕES CLÍNICAS E POSSIBILIDADES TERAPÊUTICAS 38 (3/4): 273-278, jul./dez. 2005 Capítulo VII
