Cochlear implant revision surgeries in children

ObjectiveTo report device failures, audiological signs and other reasons for revision cochlear implant surgery, and discuss indications for revision surgery.MethodsRevision procedures between November 1997 and August 2017 were retrospectively analysed. Over 20 years, 2181 cochlear implant operations were performed, and 114 patients underwent 127 revision operations.ResultsThe revision rate was 4.67 per cent. The full insertion rate for revision cochlear implant surgery was 88.2 per cent. The most frequent reasons for revision surgery were: device failure (59 per cent), wound breakdown (9.4 per cent) and electrode malposition (8.7 per cent). The device failure rate was: 2.78 per cent for Advanced Bionics, 1.82 per cent for Cochlear and 5.25 per cent for Med-El systems. The number of active electrodes was significantly increased only for Med-El devices after revision surgery. The most common complaints among 61 patients were: gradually decreased auditory performance, sudden internal device shutdown and headaches.ConclusionThe most common reason for revision surgery was device failure. Patients should be evaluated for device failure in cases of: no hearing despite appropriate follow up, side effects such as facial nerve stimulation, and rejection of speech processor use in paediatrics. After revision surgery, most patients have successful outcomes.

Background Cochlear implantation (CI) is currently a well-established method for restoring hearing to people with profound hearing loss (Blamey and Artieres, Audiol Neurotol 18:36-47, 2013; Holden and Finley, Ear Hear 34:342-360, 2013). Cochlear implantation not only affects hearing abilities, speech perception, and production, but also has an outstanding impact on the social life, activities, and self-esteem of each patient. The Nijmegen Cochlear Implant Questionnaire (NCIQ) and Parents’ Views and Experiences with pediatric Cochlear Implant Questionnaire (PVECIQ) have been developed to assess the quality of life in such patients (Damen and Beynon, Otolaryngol Head Neck Surg 136:597-604, 2007; Hirschfelder and Gräbel, Otolaryngol Head Neck Surg 138:357-362, 2008). The long-term outcome of cochlear implantation (CI) in Egypt and its influence on patients’ lives have not been investigated. This study was designed to evaluate the long-term effect of CI on speech perception and to assess the quality of life (QoL) and get insight about major problems encountered by these patients over years. Methods Forty adults and children CI users of least 5 years of CI experience were subjected to full history taking and CI outcome measures: CI questionnaires, aided sound field pure tone audiometry, and speech perception tests. Results Through QoL questionnaires, the highest scores were obtained in the physical functioning domain than in the psychological and social domains in adults, while for children, the highest scores were obtained in the general domain than in the communication and self-reliance domains. No statistically significant correlation was found between QOL questionnaires and speech tests. Conclusion Audiological evaluation including speech perception tests is not enough to reflect the true performance of CI subjects in everyday listening situations. The Arabic versions of QoL questionnaires were complementary to other outcome CI measures. Long-term evaluation for CI users is crucial.

“…A integridade do sistema auditivo é fundamental para o desenvolvimento das habilidades auditivas, desenvolvimento da fala e da linguagem. Alterações no sistema auditivo podem ser desenvolvidas em qualquer faixa etária e trazem prejuízos independentemente da idade em que essas alterações ocorrem, sendo potencialmente incapacitantes, uma vez que comprometem diretamente a comunicação com prejuízos emocionais, sociais e intelectuais (AMARAL et al, 2019;GONDIM et al, 2012).…”

Cochlear implant revision surgeries in children

Abstract: The incidence of the cochlear implant revision surgery was 4.23%. The period following the revision surgeries revealed an improvement in the subject's hearing and language performance, indicating that these surgeries are valid in most cases.
