- 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 FerreiraIntroduction 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.
- Avaliação do benefício do uso de aparelhos de amplificação sonora individual em crianças(2012) CARVALHO, Luciana Regina de Lima; LICHTIG, Ida; COUTO, Maria Inês VieiraINTRODUCTION: In Brazil, it is rare studies with using deaf children of auditory device above of seven years. OBJECTIVE: To investigate the benefit supplied for the amplification in deaf children to 7 years old to 11 years old using auditory device, under the perspective of the proper child and the adults with who it more coexists, and to verify if the time of conviviality of the adults with the child intervenes with their answers. METHOD: One is about a clinical and experimental study. They had participated of the study 48 citizens, divided in 4 distinct groups: G1- 12 deaf children; G2- 12 adults with average companionship of 40 weekly hours with the deaf child; G312 adults with average companionship of 20 weekly hours with the deaf child; G4- 12 adults with average companionship of 10 weekly hours with the deaf child. All the children were using of device bilaterally and presented auditory loss of severe or deep degree. RESULTS: The results indicate damage in the auditory abilities of the children evaluated had to the difficulties faced for them to listen to elements gifts in situations of its daily one. The time of companionship with the child did not have differences in the results between the different groups in agreement. CONCLUSION: The viability of the evaluation of the proportionate benefit for the auditory device in children was evidenced clinically on the basis of the information of the family. The device of individual sonorous amplification exerted influence in the auditory abilities of the evaluated children, although the proportionate benefit for its use to be lesser of what the waited one.
- 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.
