- Hearing preservation using topical dexamethasone alone and associated with hyaluronic acid in cochlear implantation(2015) RAMOS, Bernardo Faria; TSUJI, Robinson Koji; BENTO, Ricardo Ferreira; GOFFI-GOMEZ, Maria Valeria Schmidt; RAMOS, Henrique Faria; SAMUEL, Paola Angelica; BRITO, RubensConclusion: Topical dexamethasone associated with hyaluronic acid in cochlear implant surgery demonstrated a statistically significant difference in the preservation of low-frequency thresholds when compared with topical dexamethasone alone and a control group. Topical dexamethasone alone was not superior in hearing preservation when compared to the control group. Objective: To compare the effects of topical dexamethasone alone and associated with hyaluronic acid intraoperatively in hearing preservation in cochlear implantation. Methods: Eighteen severely to profoundly hearing-impaired adult patients with measurable hearing were divided into three groups preoperatively: cochlear implantation as a control group (group 1), cochlear implantation using topical dexamethasone intraoperatively (group 2), and cochlear implantation using topical dexamethasone associated with hyaluronic acid intraoperatively (group 3). Preimplant and postimplant low-frequency pure-tone averages (PTAs) were calculated from unaided audiograms at 125, 250, and 500 Hz. Results: The mean changes in the low-frequency PTA comparing postoperative against preoperative thresholds were 28.03 +/- 6.77 dB in group 1, 30 +/- 14.53 dB in group 2, and 7.23 +/- 6.12 dB in group 3. There was statistical difference when comparing group 3 with groups 1 and 2 using one-way ANOVA (p = 0.002) followed by Scheffe post hoc test.
- 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 deObjective. 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.
bookPart Acompanhamento pós-cirúrgico de crianças e adultos usuários de implante coclear(2015) GOFFI-GOMEZ, M. Valéria Schimidt; SILVA, Leandra Tabanez do Nascimento- 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.
