- Can the use of the CROS system provide head shadow effect contribution to unilateral Cochlear Implant Users?(2022) HOSHINO, Ana Cristina Hiromi; GOFFI-GOMEZ, Maria Valeria Schmidt; SIERRA, Paola Angelica Samuel; AGRAWAL, Smita; RODRIGUEZ, Carina; CARVALHO, Ana Claudia Martinho de; TSUJI, Robinson KojiPurpose: The aim of this study was to evaluate the contribution of the CROS system on the head shadow effect in unilateral implant users. Methods: Prospective cross-sectional study, approved by the ethics committee under protocol 2.128.869. Eleven adults with post-lingual deafness users of unilateral Advanced Bionics CI were selected. Speech recognition was evaluated with recorded words presented at 65dBA at 0o azimuth and at 90o on the side contralateral to the CI, with noise at 55dBA, using CI alone and CI + CROS system. The results were analyzed using paired t-test with a 0.05 alpha. Results: The mean speech recognition scores were significantly better with CI + CROS in relation to the condition of CI alone (p <0.05, p <0.005 and p <0.005 respectively). In the presentation at 0o azimuth, no significant differences were found. Conclusion: Users of unilateral CI without useful residual hearing for the use of hearing aids or unable to undergo bilateral surgery can benefit from the CROS device for speech recognition, especially when the speech is presented on the side contralateral to the CI.
- Central Auditory Nervous System Stimulation through the Cochlear Implant Use and Its Behavioral Impacts: A Longitudinal Study of Case Series(2021) CAVALCANTI, Marina Isabel; SILVA, Liliane Aparecida Fagundes; GOMEZ, Maria Valeria Schmidt Goffi; KOJI, Tsuji Robinson; BENTO, Ricardo Ferreira; CARVALHO, Ana Claudia Martinho de; GENTILE, Matas CarlaThe purpose of this study was to investigate, over a period of five years, the cortical maturation of the central auditory pathways and its impacts on the auditory and oral language development of children with effective use and without effective use of a Cochlear Implant (CI). A case series study was conducted with seven children who were CI users and seven children with normal hearing, with age- and gender-matched to CI users. The assessment was performed by long-latency auditory evoked potentials and auditory and oral language behavioral protocols. The results pronounced P1 latency decrease in all CI users in the first nine months. Over five years, five children with effective CI use presented decrease or stabilization of P1 latency and a gradual development of auditory and oral language skills, although, for most of the children, the electrophysiological and behavior results remained poor than their hearing peers' results. Two children who stopped the effective use of CI after the first year of activation had worsened auditory and oral language behavioral skills and presented increased P1 latency. A negative correlation was observed between behavioral measures and the P1 latency, the P1 component being considered an important clinical resource capable of measuring the cortical maturation and the behavioral evolution.
- Auditory and communicative abilities in the auditory neuropathy spectrum disorder and mutation in the Otoferlin gene: clinical cases study(2012) COSTA, Nayara Thais de Oliveira; MARTINHO-CARVALHO, Ana Claudia; CUNHA, Maria Claudia; LEWIS, Doris RuthiThis study had the aim to investigate the auditory and communicative abilities of children diagnosed with Auditory Neuropathy Spectrum Disorder due to mutation in the Otoferlin gene. It is a descriptive and qualitative study in which two siblings with this diagnosis were assessed. The procedures conducted were: speech perception tests for children with profound hearing loss, and assessment of communication abilities using the Behavioral Observation Protocol. Because they were siblings, the subjects in the study shared family and communicative context. However, they developed different communication abilities, especially regarding the use of oral language. The study showed that the Auditory Neuropathy Spectrum Disorder is a heterogeneous condition in all its aspects, and it is not possible to make generalizations or assume that cases with similar clinical features will develop similar auditory and communicative abilities, even when they are siblings. It is concluded that the acquisition of communicative abilities involves subjective factors, which should be investigated based on the uniqueness of each case.
- Telephone Usage and Cochlear Implant: Auditory Training Benefits(2015) SOUSA, Aline Faria de; CARVALHO, Ana Claudia Martinho de; COUTO, Maria Ines Vieira; TSUJI, Robinson Koji; GOFFI-GOMEZ, Maria Valéria Schmidt; BENTO, Ricardo Ferreira; MATAS, Carla Gentile; BEFI-LOPES, Debora MariaIntroduction: Difficulties with telephone use by adult users of cochlear implants (CIs) are reported as a limitation in daily life. Studies to improve the speech understanding of CI users on the telephone are scarce in the Brazilian scientific literature. Objective To develop and evaluate the effectiveness of a training program of auditory abilities on the telephone for an adult CI user. Resumed Report The subject was a 55-year-old woman with a degree in accounting who used a CI for 24 months. The program consisted of three stages: pretraining evaluation, eight sessions of advanced auditory abilities training, and post-training evaluation. Auditory abilities with CI were evaluated before and after training in three conditions: sound field, telephone with the speech processor in the microphone function, and telephone with the speech processor in the telecoil function. Speech recognition was assessed by three different lists: one with monosyllabic and dissyllabic words, another with nonsense syllables, and another one with sentences. The Client Oriented Scale of Improvement (COSI) was used to assess whether the needs established by the CI user in everyday telephone use situations improved after training. The auditory abilities training resulted in a relevant improvement in the percentage of correct answers in speech tests both in the telephone use conditions and in the sound field condition. Conclusion The results obtained with the COSI inventory indicated a performance improvement in all situations presented at the beginning of the program.
- Auditory Cortical Maturation in a Child with Cochlear Implant: Analysis of Electrophysiological and Behavioral Measures(2015) SILVA, Liliane Aparecida Fagundes; COUTO, Maria Ines Vieira; TSUJI, Robinson Koji; BENTO, Ricardo Ferreira; CARVALHO, Ana Claudia Martinho de; MATAS, Carla GentileThe purpose of this study was to longitudinally assess the behavioral and electrophysiological hearing changes of a girl inserted in a CI program, who had bilateral profound sensorineural hearing loss and underwent surgery of cochlear implantation with electrode activation at 21 months of age. She was evaluated using the P1 component of Long Latency Auditory Evoked Potential (LLAEP); speech perception tests of the Glendonald Auditory Screening Procedure (GASP); Infant Toddler Meaningful Auditory Integration Scale (IT-MAIS); and Meaningful Use of Speech Scales (MUSS). The study was conducted prior to activation and after three, nine, and 18 months of cochlear implant activation. The results of the LLAEP were compared with data from a hearing child matched by gender and chronological age. The results of the LLAEP of the child with cochlear implant showed gradual decrease in latency of the P1 component after auditory stimulation (172 ms-134 ms). In the GASP, IT-MAIS, and MUSS, gradual development of listening skills and oral language was observed. The values of the LLAEP of the hearing child were expected for chronological age (132ms128ms). The use of different clinical instruments allow a better understanding of the auditory habilitation and rehabilitation process via CI.
