    (2013) HOSHINO, Ana Cristina Hiromi; CRUZ, Dorilan Rodriguez da; GOFFI-GOMEZ, Maria Valéria Schmidt; BEFI-LOPES, Débora Maria; MATAS, Carla Gentile; FORTUNATO-TAVARES, Talita M.; TSUJI, Robinson Koji
    PURPOSE: to evaluate how long after activation one can achieve the desired auditory thresholds in individuals multichannel cochlear implant users from different age groups. METHOD: a retrospective cross-sectional from a database, approved by CEP / FMUSP, under number 779/06. Individuals implanted between January 2005 and September 2008, whose files had preoperative audiometric data and 3, 6 and 12 months after CI were included. Seventy-two patients fulfilled the criteria, and they were divided in two groups according to age: group I (17 year old) and GII (18-66 year old). Analysis of variance (ANOVA) of one factor in order to verify the interaction between the mean threshold and time after CI were used. RESULTS: we observed that 15 of the GI have reached around 30dBNA thresholds at 3 months after implant. The same happened to 26 patients of GII. We found significant interaction between time (F (3.140) = 91.973, p = 0.00) and the average hearing thresholds. Post-hoc analysis in the GI group were statistically significant differences for comparisons between HA and 3 months after implantation (p = 0.00) and between 3 and 12 months (p = 0.28). For GII only for comparison between HA and 3 months (p = 0.00). CONCLUSION: a significant hearing change may be observed beginning from three months after IC, but this result is not found in all implanted subjects.

    (2018) GRASEL, Signe; GRETERS, Mario; GOFFI-GOMEZ, Maria Valeria Schimidt; BITTAR, Roseli; WEBER, Raimar; OITICICA, Jeanne; BENTO, Ricardo Ferreira
    Introduction The P3 cognitive evoked potential is recorded when a subject correctly identifies, evaluates and processes two different auditory stimuli. Objective to evaluate the latency and amplitude of the P3 evoked potential in 26 cochlear implant users with post-lingual deafness with good or poor speech recognition scores as compared with normal hearing subjects matched for age and educational level. Methods In this prospective cohort study, auditory cortical responses were recorded from 26 post-lingual deaf adult cochlear implant users (19 with good and 7 with poor speech recognition scores) and 26 control subjects. Results There was a significant difference in the P3 latency between cochlear implant users with poor speech recognition scores (G-) and their control group (CG) (p = 0.04), and between G-and cochlear implant users with good speech discrimination (G+) (p = 0.01). We found no significant difference in the P3 latency between the CG and G+. In this study, all G-patients had deafness due to meningitis, which suggests that higher auditory function was impaired too. Conclusion Post-lingual deaf adult cochlear implant users in the G-group had prolonged P3 latencies as compared with the CG and the cochlear implant users in the G+ group. The amplitudes were similar between patients and controls. All G-subjects were deaf due to meningitis. These findings suggest that meningitis may have deleterious effects not only on the peripheral auditory system but on the central auditory processing as well.

    Important Factors in the Cognitive Development of Children with Hearing Impairment: Case Studies of Candidates for Cochlear Implants
    (2014) NASRALLA, Heloisa Romeiro; GOMEZ, Maria Valéria Schimidt Goffi; MAGALHAES, Ana Tereza; BENTO, Ricardo Ferreira
    Introduction The factors that affect the development of children with and without hearing disabilities are similar, provided their innate communication abilities are taken into account. Parents need to mourn the loss of the expected normally hearing child, and it is important that parents create bonds of affection with their child. Objective To conduct a postevaluation of the development and cognition of 20 candidates for cochlear implants between 1 and 13 years of age and to observe important factors in their development. Methods The following instruments were used in accordance with their individual merits: interviews with parents; the Vineland Social Maturity Scale; the Columbia Maturity Scale; free drawings; Bender and Pre-Bender testing; and pedagogical tests. Results The results are described. Conclusion Parental acceptance of a child's deafness proved to be the starting point for the child's verbal or gestural communication development, as well as for cognitive, motor, and emotional development. If the association between deafness and fine motor skills (with or without multiple disabilities) undermines the development of a child's speech, it does not greatly affect communication when the child interacts with his or her peers and receives maternal stimulation. Overprotection and poor sociability make children less independent, impairs their development, and causes low self-esteem. Further observational studies are warranted to determine how cochlear implants contribute to patient recovery.

    Retrolabyrinthine approach for cochlear nerve preservation in neurofibromatosis type 2 and simultaneous cochlear implantation
    (2013) BENTO, Ricardo Ferreira; MONTEIRO, Tatiana Alves; BITTENCOURT, Aline Gomes; GOFFI-GOMEZ, Maria Valeria Schmidt; BRITO, Rubens de
    INTRODUCTION: Few cases of cochlear implantation (CI) in neurofibromatosis type 2 (NF2) patients had been reported in the literature. The approaches described were translabyrinthine, retrosigmoid or middle cranial fossa. OBJECTIVES: To describe a case of a NF2- deafened-patient who underwent to vestibular schwannoma resection via RLA with cochlear nerve preservation and CI through the round window, at the same surgical time. RESUMED REPORT: A 36-year-old woman with severe bilateral hearing loss due to NF2 was submitted to vestibular schwannoma resection and simultaneous CI. Functional assessment of cochlear nerve was performed by electrical promontory stimulation. Complete tumor removal was accomplishment via RLA with anatomic and functional cochlear and facial nerve preservation. Cochlear electrode array was partially inserted via round window. Sound field hearing threshold improvement was achieved. Mean tonal threshold was 46.2 dB HL. The patient could only detect environmental sounds and human voice but cannot discriminate vowels, words nor do sentences at 2 years of follow-up. CONCLUSION: Cochlear implantation is a feasible auditory restoration option in NF2 when cochlear anatomic and functional nerve preservation is achieved. The RLA is adequate for this purpose and features as an option for hearing preservation in NF2 patients.

    Are Auditory Steady-State Responses Useful to Evaluate Severe-to-Profound Hearing Loss in Children?
    (2015) GRASEL, Signe Schuster; ALMEIDA, Edigar Rezende de; BECK, Roberto Miquelino de Oliveira; GOFFI-GOMEZ, Maria Valeria Schmidt; RAMOS, Henrique Faria; ROSSI, Amanda Costa; TSUJI, Robinson Koji; BENTO, Ricardo Ferreira; BRITO, Rubens de
    Objective. To evaluate Auditory Steady-State Responses (ASSR) at high intensities in pediatric cochlear implant candidates and to compare the results to behavioral tests responses. Methods. This prospective study evaluated 42 children with suspected severe-to-profound hearing loss, aged from 3 to 72 months. All had absent ABR and OAE responses. ASSR were evoked using binaural single frequency stimuli at 110 dB HL with a 10 dB down-seeking procedure. ASSR and behavioral test results were compared. Results. Forty-two subjects completed both ASSR and behavioral evaluation. Eleven children (26.2%) had bilateral responses. Four (9.5%) showed unilateral responses in at least two frequencies, all confirmed by behavioral results. Overall 61 ASSR responses were obtained, most (37.7%) in 500 Hz. Mean thresholds were between 101.3 and 104.2 dB HL. Among 27 subjects with absent ASSR, fifteen had no behavioral responses. Seven subjects showed behavioral responses with absent ASSR responses. No spurious ASSR responses were observed at 100 or 110 dB HL. Conclusion. ASSR is a valuable tool to detect residual hearing. No false-positive ASSR results were observed among 42 children, but in seven cases with absent ASSR, the test underestimated residual hearing as compared to the behavioral responses.

    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 Koji
    Purpose: 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.

    Longitudinal Analysis of the Absence of Intraoperative Neural Response Telemetry in Children using Cochlear Implants
    (2014) MOURA, Amanda Christina Gomes de; GOFFI-GOMEZ, Maria Valéria Schmidt; COUTO, Maria Ines Vieira; BRITO, Rubens; TSUJI, Robinson Koji; BEFI-LOPES, Debora Maria; MATAS, Carla Gentile; BENTO, Ricardo Ferreira
    Introduction Currently the cochlear implant allows access to sounds in individuals with profound hearing loss. The objective methods used to verify the integrity of the cochlear device and the electrophysiologic response of users have noted these improvements. Objective To establish whether the evoked compound action potential of the auditory nerve can appear after electrical stimulation when it is absent intraoperatively. Methods The clinical records of children implanted with the Nucleus Freedom (Cochlear Ltd., Australia) (CI24RE) cochlear implant between January 2009 and January 2010 with at least 6 months of use were evaluated. The neural response telemetry (NRT) thresholds of electrodes 1, 6, 11, 16, and 22 during surgery and after at least 3 months of implant use were analyzed and correlated with etiology, length of auditory deprivation, and chronological age. These data were compared between a group of children exhibiting responses in all of the tested electrodes and a group of children who had at least one absent response. Results The sample was composed of clinical records of 51 children. From these, 21% (11) showed no NRT in at least one of the tested electrodes. After an average of 4.9 months of stimulation, the number of individuals exhibiting absent responses decreased from 21 to 11% (n = 6). Conclusion It is feasible that absent responses present after a period of electrical stimulation. In our sample, 45% (n = 5) of the patients with intraoperative absence exhibited a positive response after an average of 4.9 months of continued electrical stimulation.

    ABSTRACT Purpose To evaluate satisfaction and quality of life of users of Auditory Implant Brainstem. Methods This is a cross-sectional and descriptive study conducted at Divisão de Clínica Otorrinolaringológica of Hospital das Clínicas of Faculdade de Medicina da Universidade de São Paulo, Brazil. For the research, 19 users of an Auditory Brainstem Implant answered the following questionnaires: KINDLR (Questionnaire for Measuring Health-Related Quality of Life in Children and Adolescents), for children and adolescents, their parents and/or caregivers; WHOQOL-BREF questionnaire, for adult participants; and the Satisfaction with Amplification in Daily Life (SADL) questionnaire culturally adapted to Brazilian Portuguese. Results The quality of life of children using Auditory Brainstem Implant from the perspective of their parents showed global results above average, as for most domains, except for the emotional well-being domain. Adults showed results above average for all domains. Regarding satisfaction with the device, the adult users of auditory brainstem implant were satisfied in general, except with regard to personal image. The parents of the children showed dissatisfaction in all subscales, except for the subscale of services and cost. Conclusion The results indicated that although patients are dissatisfied with the device in some aspects, overall the quality of life was rated as good for most of the aspects assessed.

    Prevalence of Contralateral Hearing Aid Use in Adults with Cochlear Implants
    (2013) YAMAGUCHI, Cintia Tizue; GOFFI-GOMEZ, Maria Valeria Schmidt
    Introduction  The exclusive use of a cochlear implant (CI) in one ear allows patients to effectively hear speech in a quiet environment. However, in environments with competing noise, the processing of multiple sounds becomes complex. In an attempt to promote binaural hearing in a noninvasive manner, the use of a hearing aid in the nonimplanted ear is suggested for patients with a unilateral CI. Aims  To identify the prevalence of hearing aid use in the contralateral ear in adults who already have a CI; to determine the reasons why some patients do not use contralateral hearing aids (CHAs); and to analyze the effects of residual hearing in CHA users. Materials and Methods  This is a clinical study in 82 adult patients with CI implants who responded to a questionnaire designed to determine current use of CHA. Results  In our patient sample, 70 CHA nonusers were identified. The prevalence of CHA users was determined to be 12% with a 95% confidence interval of 11 to 13%. About 58.2% of the CHA nonusers reported a lack of noticeable benefit even after wearing hearing aids, and 23.6% reported not having received the option to use a CHA. CHA users had a pure tone average of 107-dB hearing level, whereas CHA nonusers had a pure tone average of 117-dB hearing level. Conclusion  The prevalence of the use of a CHA is low in our study. We attribute the low use of a CHA to either a lack of residual hearing or to a lack of benefit from the amplification.
