Surdez pós-lingual: benefícios do implante coclear versus prótese auditiva convencional

Abstract

The technological advances in cochlear implants and processing strategies have enabled subjects affected by severe to profound hearing loss to hear sounds and recognize speech in various different degrees. The variability of hearing outcomes in subjects with post-lingual deafness has been significant and cochlear implant indications have been extended to include an ever larger population.Objective: This paper aims to look into the groups of post-lingual deafness patients to find where cochlear implants have yielded better outcomes than conventional hearing aids. Materials and Methods:Review the literature available on databases SciELO, Cochrane, MEDLINE, and LILACS-BIREME. The publications selected for review were rated as A or B on evidence strength on the day of the review. Their authors analyzed and compared hearing aids and cochlear implants in populations of post-lingually deaf patients. Study Design: Systematic review.Results: Eleven out of the 2,169 papers searched were found to be pertinent to the topic and were rated B for evidence strength. Six studies were prospective cohort trials, four were cross-sectional studies and one was a clinical trial. Conclusion:The assessment done on the benefits yielded by post-lingually deaf subjects from cochlear implants showed that they are effective and provide for better results than conventional hearing aids.

Temporal processing in postlingual adult users of cochlear implant

“…Currently, the cochlear implant (CI) is considered the most effective clinical resource to rehabilitate the hearing of patients who have not benefitted from the use of an individual sound amplification device (ISAD). 1 …”

Habilidades auditivas e de linguagem de crianças usuárias de implante coclear: análise dos marcadores clínicos de desenvolvimento

“…O Implante Coclear (IC) é considerado um importante recurso tecnológico para as pessoas com deficiência auditiva sensorioneural de grau severo a profundo (Baumgartner et al, 2002;Robbins;Green;Waltzman, 2004;O'Donoghue, 2007;Umat et al, 2010;Bittencourt et al, 2012) que não se beneficiam do uso dos aparelhos de amplificação para o desenvolvimento das habilidades auditivas e de linguagem (Robinson et al, 2012;Dunn et al, 2014). É consenso na literatura que a evolução das habilidades auditivas e de linguagem falada é variável entre as crianças, e nem todas tem a capacidade de alcançar os resultados esperados nos primeiros anos de uso do IC.…”
