- Auditory Brainstem Implants in Children: Results Based on a Review of the Literature(2014) MONSANTO, Rafael da Costa; BITTENCOURT, Aline Gomes; BOBATO NETO, Natal Jose; BEILKE, Silvia Carolina Almeida; LIMA, Nelson Fabricio Goetten de; LORENZETTI, Fabio Tadeu Moura; SALOMONE, RaquelThe 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.
- Surdez pré-lingual: benefícios do implante coclear versus prótese auditiva convencional(2012) BITTENCOURT, Aline Gomes; TORRE, Ana Adelina Giantomassi Della; BENTO, Ricardo Ferreira; TSUJI, Robinson Koji; BRITO, Rubens deINTRODUCTION: The majority of patients with hearing loss, including those with severe hearing loss, benefits from the use of hearing aids. The cochlear implant is believed to achieve better results in a child with hearing loss in cases where the severity of disability renders hearing aids incapable of providing adequate sound information, as they require sufficient cochlear reserve so that acoustic detention occurs. OBJECTIVE: To assess if cochlear implants provide more benefit than conventional hearing aids in prelingually deaf patients. SUMMARY OF THE FINDINGS : The study was a systematic review of scientific papers selected by a search of the SciELO, Cochrane, MEDLINE, and LILACS-BIREME databases. Among the 2169 articles found, 12 studies proved relevant to the issue and presented an evidence strength rating of B. No publications rated evidence strength A. Seven of the studies analyzed were prospective cohorts and 5 were cross-sectional studies. CONCLUSION: Based on several studies, cochlear implants were demonstrated to be the best current alternative for bilateral severe or profound hearing loss, achieving better results in speech perception and development in prelingual children when compared to conventional hearing aids.
- Cochlear implantation trough the middle cranial fossa: a novel approach to access the basal turn of the cochlea(2013) BITTENCOURT, Aline Gomes; TSUJI, Robinson Koji; TEMPESTINI, Joao Paulo Ratto; JACOMO, Alfredo Luiz; BENTO, Ricardo Ferreira; BRITO, Rubens deThe classic approach for cochlear implant surgery includes mastoidectomy and posterior tympanotomy. The middle cranial fossa approach is a proven alternative, but it has been used only sporadically and inconsistently in cochlear implantation. Objective: To describe a new approach to expose the basal turn of the cochlea in cochlear implant surgery through the middle cranial fossa. Method: Fifty temporal bones were dissected in this anatomic study of the temporal bone. Cochleostomies were performed through the middle cranial fossa approach in the most superficial portion of the basal turn of the cochlea, using the meatal plane and the superior petrous sinus as landmarks. The lateral wall of the internal acoustic canal was dissected after the petrous apex had been drilled and stripped. The dissected wall of the inner acoustic canal was followed longitudinally to the cochleostomy. Results: Only the superficial portion of the basal turn of the cochlea was opened in the fifty temporal bones included in this study. The exposure of the basal turn of the cochlea allowed the visualization of the scala tympani and the scala vestibuli, which enabled the array to be easily inserted through the scala tympani. Conclusion: The proposed approach is simple to use and provides sufficient exposure of the basal turn of the cochlea.
- Post-lingual deafness: benefits of cochlear implants vs. conventional hearing aids(2012) BITTENCOURT, Aline Gomes; IKARI, Liliane Satomi; TORRE, Ana Adelina Giantomassi Della; BENTO, Ricardo Ferreira; TSUJI, Robinson Koji; BRITO NETO, Rubens Vuono deThe 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.
