    (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.

    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.

    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.

    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.

    Avaliação do Naída CI Q70 e estratégia UltraZoom para o reconhecimento de fala em situações reverberantes e com ruído competitivo
    (2020) SAMUEL, Paola Angelica; GOFFI-GOMEZ, Maria Valéria Schmidt; HOSHINO, Ana Cristina; AGRAWAL, Smita; RODRIGUEZ, Carina; TSUJI, Robinson Koji; BENTO, Ricardo Ferreira
    Abstract Purpose 1) To measure speech understanding in noise with the Naída Q70 in the omnidirectional microphone mode (T-Mic) and adaptive directional microphone mode (UltraZoom) in reverberating acoustics and noisy conditions. 2) To measure improvement in speech understanding with use of the Advanced Bionics (AB) Naída Q70 sound processor for existing Harmony users. Methods Seven adult unilateral cochlear implant (CI) recipients, who were experienced users of the Harmony sound processor, participated in the study. Sentence recognition was evaluated in quiet in a reverberating room, with Harmony and Naída CI Q70 processors. Effectiveness of Naída CI Q70’s UltraZoom directional microphone was evaluated in noise. Target stimuli were recorded Portuguese sentences presented from 0° azimuth. Twenty-talker babble was presented at +5dB SNR from ±90° azimuth. In addition to sentence recognition, the participants also rated the clarity of sound and difficulty of listening in the various test conditions. In order to evaluate the outcomes under more realistic acoustic conditions, tests were conducted in a non-sound treated reverberant room (RT60 of 553 ms and noise floor of 42.7 dBA (Leq). Results The average sentence recognition in quiet in the reverberant non-sound treated room was 38.5% with the Harmony and 66.5% with Naída CI Q70. The average sentence recognition score in noise was 40.5% with Naída CI Q70 without UltraZoom and 64.5% with UltraZoom. For subjective ratings of sound clarity and listening ease in noise no difference were identified between the test conditions. Conclusion For experienced users of the Harmony sound processor, speech understanding in quiet in a reverberating room was significantly improved with the Naída CI Q70. The use of an adaptive directional microphone technology (UltraZoom) enhanced speech perception in noise.

    A tecnologia a favor da educação continuada no implante coclear
    (2021) MAGALHÃES, Ana Tereza de Matos; GOMEZ, Maria Valéria Schimdt Goffi; TSUJI, Robinson Koji; BENTO, Ricardo Ferreira
    ABSTRACT Purpose To evaluate the teleconsultation synchronously in the mapping of the cochlear implant (CI) as an ongoing professional development tool in training programmes for audiologists. Methods It was a prospective longitudinal study, in the form of clinical preceptor with teleconsultation in a synchronous way directed at assisting the mapping of CI users. Distance learning was offered to fellow audiologists in a hospital and the audiology tutor in the remote unit. The chosen platform allowed the tutor to view and perform interventions on the CI mapping screen. Three questionnaires covering teaching markers were applied; the quality and importance of teleconsultation; interaction between professionals; and self-assessment of confidence in carrying out the mapping steps before and after teleconsultations. Results Seven audiologists participated; 268 consultations were analyzed over three years. The clinical markers showed, on average and individually, that there is a statistical correlation with a decrease in the number of total interventions, in the interventions of CI mapping and clinical reasoning throughout the sessions. The average of the scores of the importance of teleconsultation was 9.7 and the interaction with the tutor was 9.3. In the self-assessment, all audiologists responded that they were “not at all/not very confident” for the mapping steps before the intervention, and at the end of the course they responded “moderately/very confident” for the same steps. Conclusion The use of synchronous teleconsultation was feasible and efficient as a teaching tool for audiologists. It was possible to observe the decrease in the number of interventions over time, evidencing the learning curve.

    Cochlear implants and bacterial meningitis: a speech recognition study in paired samples
    (2013) BRITO, Rubens de; BITTENCOURT, Aline Gomes; GOFFI-GOMEZ, Maria Valéria; MAGALHÃES, Ana Tereza; SAMUEL, Paola; TSUJI, Robinson Koji; BENTO, Ricardo Ferreira
    INTRODUCTION: Cochlear implants may guarantee sound perception and the ability to detect speech at a close-to-normal hearing intensity; however, differences have been observed among implantees in terms of performance on discrimination tests and speech recognition. OBJECTIVE: To identify whether patients with post-meningitis deafness perform similarly to patients with hearing loss due to other causes. METHOD: A retrospective clinical study involving post-lingual patients who had been using Nucleus-22 or Nucleus-24 cochlear implants for at least 1 year. These patients were matched with respect to age (± 2 years), time since the onset of deafness (± 1 year), and the duration of implant use with implant users who had hearing loss due to other causes. Speech perception was assessed using the Portuguese version of the Latin-American Protocol for the Evaluation of Cochlear Implants. RESULTS: The sample consisted of 52 individuals (26 in each of the 2 groups). The post-meningitic group had a median of 18.5 active electrodes. The group with hearing loss due to other causes had a median of 21, but no significant statistical difference was observed (p = 0.07). The results of closed- and open-set speech recognition tests showed great variability in speech recognition between the studied groups. These differences were more pronounced for the most difficult listening tasks, such as the medial consonant task (in the vowel-consonant-vowel format). CONCLUSION: Cochlear implant recipients with hearing loss due to bacterial meningitis, who had been using the device for 1 year performed more poorly on closed- and open-set speech recognition tests than did implant recipients with hearing loss due to other causes.

    Vocabulário expressivo em crianças usuárias de implante coclear
    (2017) COLALTO, Claudia Aparecida; GOFFI-GOMEZ, Maria Valéria Schmidt; MAGALHÃES, Ana Tereza de Matos; SAMUEL, Paola Angélica; HOSHINO, Ana Cristina Hiromi; PORTO, Bruna Lins; TSUJI, Robinson Koji
    ABSTRACT Objective: to verify whether children with cochlear implants (CI) acquire vocabulary at the same pace as normally hearing children, and which factors influence their acquisition. Methods: the vocabulary test of the ABFW was performed on 20 children who had been using the cochlear implant for at least three years. Historical information, such as age at time of implant, hearing age (i.e., at time of implant use), and family participation in the rehabilitation process, was gathered from patients’ files. Correlation statistical analysis was then performed. Results: it was observed that children with CI may acquire vocabulary similar to that of hearing children, depending on many aspects. The age at time of implantation and hearing age did not significantly correlate to the vocabulary results. The factor that demonstrated statistical significance was family participation, which showed a positive correlation: the more the family was involved in the rehabilitation process, the better the children’s results on the vocabulary test. Conclusion: it was, thus, possible to conclude that children with CI develop their vocabulary in a similar manner as hearing children, depending on factors that transcend the child’s age at time of implantation and hearing age. Family participation, in the rehabilitation process, was shown to be of critical importance in the child’s vocabulary development.

    (2022) UEDA, Cynthia Harumi Yokoyama; MAGALHÃES, Ana Tereza de Matos; SADOWSKI, Tatiana; TSUJI, Robinson Koji; GOFFI-GOMEZ, Maria Valéria Schmidt
    ABSTRACT Purpose To identify the development of initial auditory skills in children with unilateral and bilateral cochlear implant during the first year of use. Methods Retrospective longitudinal study of medical records of children who received cochlear implant under the age of four, separated into two groups. The first, composed of children implanted unilaterally and the second, by children implanted and simultaneously. Data on the IT-MAIS scale (Infant-Toddler Meaningful Auditory Integration Scale) were collected before surgery and three months, six months and one year after surgery. These results were compared with the existing Clinical Markers. In addition, the family’s classification was noted, according to the Family Involvement Assessment Scale. Results The data of 29 children with bilateral cochlear implant and 30 children with unilateral cochlear implant were evaluated. The IT-MAIS score of the two groups was similar to the Clinical Markers. Regarding the Family Involvement Assessment Scale, there was a difference, showing that families in the bilateral group were more involved. Conclusion In the first year of use of the cochlear implant, the development of children implanted bilaterally did not differ from the development of children implanted unilaterally, suggesting that initial auditory skills are likely to develop with unilateral auditory input.
