ABSTRACT
UNLABELLED: Cochlear implants represent a significant breakthrough in the treatment of hearing loss. Evidence indicates bilateral hearing brings significant benefits to patients, particularly when binaural hearing is offered. OBJECTIVE: To describe the first case of implantation of a Digisonic SP® Binaural Neurelec device in Brazil (the third implant placed in the Americas, after Mexico and Colombia) and the chosen surgical approach. METHOD: Description of a surgical approach. RESULTS: The procedure was successfully completed. DISCUSSION: The squelch effect, binaural summation, location of the sound source, and the shadow effect of the head are listed among the reasons to explain the superiority of binaural rehabilitation. Cost of treatment must be considered in the development of public health policies. CONCLUSION: The cost of cochlear implants has been one of the main impediments to bilateral rehabilitation. The Digisonic SP® Binaural Neurelec device addresses this issue and exposes patients to less risk through a minimally invasive implantation procedure.

O implante coclear é um grande avanço no tratamento da surdez. Há grandes evidências que a audição bilateral traz diversas vantagens ao ser humano e muito mais quando se trata de audição binaural. OBJETIVO: Este artigo tem por objetivo descrever o primeiro caso operado no Brasil, sendo o terceiro país das Américas (México e Colômbia) a realizar, com implante binaural Neurelec Digisonic SP® demonstrando a técnica cirúrgica. MÉTODO: Descrição da técnica cirúrgica. RESULTADOS: Ver técnica cirúrgica. Procedimento ocorreu sem intercorrências. DISCUSSÃO: O efeito "squelch", a somação binaural, a localização da fonte sonora e o efeito sombra da cabeça são umas das principais razões que justificam a superioridade da reabilitação binaural. O custo do tratamento deve ser levado em conta em políticas de saúde pública. CONCLUSÃO: Custo do implante coclear é um dos grandes limitadores da bilateralidade na reabilitação desse grupo de pacientes, porém, com essa tecnologia, é possível solucionar esse problema, expondo o paciente a poucos riscos, com o uso de uma técnica cirúrgica pouco invasiva.

O implante coclear para pacientes com disacusia grave/profunda revolucionou o modo com que estes interagem com o meio ambiente. A Neurelec desenvolveu um sistema que permite fixação com uso de dois simples parafusos de titânio, sem necessidade de broqueamento do osso do crânio do paciente. Este artigo teve o objetivo de descrever uma casuística de pacientes submetidos a implante coclear com o Digisonic® SP, para mostrar os resultados cirúrgicos e detalhes do procedimento. MÉTODO: Estudo retrospectivo que avaliou os pacientes, no período de 18 meses, submetidos a implante coclear com o Digisonic® SP. Todos os pacientes eram pós-linguais. Coleta dos dados realizada por meio da análise dos prontuários dos pacientes, além de questionário padronizado aplicado nos cirurgiões que realizaram o procedimento. RESULTADOS: Os seis casos implantados com o Digisonic® SP foram realizados por cirurgiões experientes e o tempo cirúrgico variou de 95 a 203 minutos (média de 135 minutos), que é menor do que o descrito com outras formas de fixação. Não houve nenhum tipo de complicação e o ganho auditivo foi satisfatório. CONCLUSÃO: O implante Digisonic® SP desenvolvido pela Neurelec apresentou bons resultados audiológicos em adultos, tempo de cirurgia menor e não ocorreram complicações cirúrgicas ou pós-operatórias.
Cochlear implants have revolutionized the way patients affected by severe hearing loss experience the world. Neurelec developed a fixation system with two titanium screws that requires no skull bone drilling. OBJECTIVE: To describe the outcomes and procedure-related details of a series of patients implanted with the Digisonic® SP cochlear implant. METHOD: This retrospective study analyzed patients submitted to cochlear implant placement within a period of 18 months. All patients had postlingual hearing impairment. Data was collected from patient charts and standard questionnaires answered by the surgeons in charge of carrying out the procedures. RESULTS: The six patients offered the Digisonic® SP cochlear implants were operated by experienced surgeons. The procedures took 95 to 203 minutes (mean = 135') to be completed, which is less time than what has been described for other fixation approaches. No complications were recorded and hearing improvement was satisfactory. CONCLUSION: The Digisonic® SP cochlear implant developed by Neurelec offered good audiological results for adult patients, shorter surgery time, and no surgical or postoperative complications.
