Abstract Introduction: Traumatic brain injury can impair the central auditory pathways and auditory cortex. Hence, individuals who suffered a traumatic brain injury may be at risk of central auditory processing disorders, which can be identified with behavioral tests that assess central auditory function. Objective: To characterize and compare the performance of children and adolescents with and without a history of traumatic brain injury in behavioral tests that assess central auditory processing. Method: The sample comprised 8- to 18-year-old individuals of both sexes who suffered moderate or severe closed traumatic brain injury 3 to 24 months before their participation in the study and whose hearing thresholds were normal. These individuals were matched for sex and age with other subjects without a history of traumatic brain injury and submitted to behavioral assessment of the central auditory processing with special tests to assess hearing skills (namely, auditory closure, figure-ground, and temporal processing), selected according to their chronological age and response-ability. Results: The study group performed statistically worse than the comparison group in auditory closure, figure-ground in verbal dichotic listening, and temporal ordering. The central auditory processing tests with abnormal results in the comparison group were different from those in the study group. Conclusion: Central auditory processing disorders were identified in all subjects of the study group, especially involving auditory closure and temporal processing skills, in comparison with subjects without a history of traumatic brain injury.

Abstract Introduction Dysphonia is an oral communication disorder. The voice and hearing are interrelated aspects. Hearing is an important sensory input for monitoring the vocal pattern. The relation between hearing abilities and dysphonia represents a contribution both in scientific and in clinical terms, especially in cases in which satisfactory results are not achieved in the therapeutic process. Objective To characterize long-latency auditory evoked potential (P300) with tonal and complex stimuli, and to make a behavioral evaluation of auditory processing in adults with behavioral dysphonia. Method The sample used for the present study consisted of 20 subjects from both genders with ages ranging from 18 and 58, who were diagnosed with behavioral dysphonia. The evaluations occurred in a single 2-hour session, in which the procedures of clinical history, pure tone and speech audiometries, acoustic immittance measures, and behavioral and electrophysiological evaluations of auditory processing were performed. Results The descriptive measures of P3 latency elicited by tonal and complex stimuli showed similar results for the right and left ears, without statistically significant differences. In the qualitative analysis, the results observed were within the normality patterns for the P3 component for both tonal and complex stimuli. As for the behavioral evaluation of auditory processing, abnormal results were observed in 100% of the sample. Abnormalities were found in the auditory skills of ordering and temporal resolution and figure-background obtained from the duration pattern, random gap detection, and dichotic tests (syllables and words), respectively. Conclusion The evaluated patients presented central auditory processing disorder, evidenced by behavioral assessment.

The appropriate statistical tests were applied considering a p-value less than 0.05. Results: questions Q1, Q2, Q4, Q7, Q8 and Q11 showed statistically significant results and improvement in behaviors after the acoustically controlled auditory training. On the other hand, questions Q3 and Q10 showed a tendency towards significance and the total score in the post time period increased in relation to the pre-moment, pointing to a statistically significant difference that represents complaint reductions. Conclusion: the subjective perception of the individuals and their family members could be identified by the application of SAB in the pre and post auditory training, revealing an improvement in auditory and attention behaviors.

Abstract Introduction The auditory structures of the brainstem are involved in binaural interaction, which contributes to sound location and auditory figure-background perception. Objective To investigate the performance of young adults in the masking level difference (MLD) test, brainstem auditory-evoked potentials (BAEPs) with click stimulus, and frequency-following response (FFR), as well as to verify the correlation between the findings, considering the topographic origin of the components of these procedures. Methods A total of 20 female subjects between 18 and 30 years of age, with normal hearing and no complaints concerning central auditory processing underwent a basic audiological evaluation, as well as the MLD test, BAEP and FFR. Results The mean result on the MLD test was of 10.70 dB. There was a statistically significant difference in the absolute latencies of waves I, III and V in the BAEPs of the ears. A change in the FFR characterized by the absence of the C, E and F waves was noticed. There was a statistically significant difference in the positive correlation of wave V in the BAEPs with the MLD. There was a statistically significant difference in the positive correlation of the mean MLD and the V, A and F components of the FFR. Conclusion The mean MLD was adequate. In the BAEPs, we observed that the click stimulus transmission occurred faster in the right ear. The FFR showed absence of some components. The mean MLD correlated positively with the BAEPs and FFR.

ABSTRACT Purpose: to verify the functioning of the outer hair cells and the medial efferent olivocochlear system, and the integrity of the auditory pathways in the brainstem up to the auditory cortex, in aphasic individuals. Methods: the sample comprised 20 individuals - 10 without aphasia and 10 with it, aged from 21 to 58 years. The procedures used were the research of the otoacoustic emissions by a transient stimulus with and without noise, and the cognitive potential (tone-burst and speech stimuli). The findings were analyzed based on descriptive statistics. Results: the suppression effect was more present in individuals without aphasia when compared with the aphasic ones. In the cognitive potential, the mean latency values of P3 was within normality standards, with a higher latency in the individuals presented with aphasia for the tone-burst stimulus in both ears. A statistically significant difference of the P3-N2 amplitude was observed for the tone-burst stimulus, comparing the ears in both groups, and for speech stimulus only to the left ear in both groups. Conclusions: aphasic individuals did not present significant differences regarding suppression of the otoacoustic emissions. As for the cognitive potential, the aphasic individuals presented higher latency values when compared to those with no aphasia.

RESUMO Objetivos: verificar o funcionamento das células ciliadas externas e do sistema olivococlear eferente medial e a integridade das vias auditivas no tronco encefálico até o córtex auditivo, em indivíduos afásicos. Métodos: a amostra foi composta por 20 indivíduos, sendo 10 indivíduos sem afasia e 10 indivíduos afásicos, com idades entre 21 e 58 anos.

ABSTRACT Purpose: to describe the audiological and otoacoustic emission findings in patients who had head and neck cancer and compare them with individuals without the disease. Methods: a comparative, cross-sectional, observational study encompassing two groups: Study: individuals with a history of head and neck cancer, submitted to chemotherapy and/or radiotherapy; Control: individuals without the disease. The sample comprised 23 individuals in each group, matched for age and gender. Procedures in which the groups were compared: meatoscopy; pure-tone threshold and high-frequency audiometry; speech audiometry; transient-evoked otoacoustic emissions. Statistical tests: Pearson’s chi-square; Fisher’s exact; two-proportion Z-test; Wilcoxon; Mann-Whitney; Student’s t-test. Results: the comparison between the groups revealed statistically significant differences at the 3, 6, 8, 10, and 12.5 kHz frequencies in the pure-tone threshold audiometry, with better pure-tone auditory thresholds in the control group. No significant differences were observed between the groups in the otoacoustic emissions regarding the general response and frequency band. Conclusion: individuals with a history of head and neck cancer had higher pure-tone auditory thresholds than their controls, especially at the higher frequencies. This evidences the deleterious effect of ototoxicity on the peripheral auditory system of adults. The otoacoustic emissions were similar in the two groups.

Abstract Introduction The mismatch negativity (MMN) is a negative long-latency auditory potential elicited by any discriminable change in a repetitive aspect of auditory stimulation. This evoked potential can provide cortical information about the sound processing, including in children who use cochlear implants. Objective To identify MMN characteristics regarding latency, amplitude, and wave area in cochlear implanted children and to identify associations among language development, speech perception and family involvement. Methods This is a descriptive, observational, cross-sectional study, which compared two groups: study group-children with cochlear implant, and control group-hearing children. The children were submitted to MMN evaluation with non-verbal tone burst stimulus, differing in frequency in sound field at 70 dBHL, with SmartEP equipment (Intelligent Hearing Systems, Miami, FL, USA). Speech perception and language development questionnaires were also applied, and the family participation in the rehabilitation process was classified. Results The occurrence ofMMNwas 73.3% for the control group and 53.3% for the study group. Values of latency, amplitude and area of MMN of children using cochlear implants were similar tothose ofhearingchildren, anddidnot differbetweengroups. The occurrence of MMN was not correlated to the variables of hearing, language and family categories. Conclusion Children with cochlear implants showed similar MMN responses to those of the children in the control group, withmean latency, amplitude andarea of 208.9ms (±12.8), -2.37 μV (±0.38) and 86.5 μVms (±23.4), respectively. There was no correlation between the presence of MMN and children’s performance in the auditory and language development tests or family involvement during rehabilitation.

OBJECTIVES: To characterize the audiometric evaluation and acoustic immittance measures in different types of mucopolysaccharidosis. METHOD: Fifty-three mucopolysaccharidosis patients were evaluated. The classification consisted of type I (Hurler syndrome, Hurler-Scheie and Scheie syndrome), type II (Hunter syndrome), type III (Sanfilippo syndrome), type IV (Morquio syndrome), and type VI (Maroteaux-Lamy syndrome). Immittance audiometry and play or conventional threshold tone audiometry were used to obtain auditory thresholds and were chosen according to the patient’s chronological age and ability to understand/respond to the procedure. The findings were analyzed using descriptive statistics and considering the recommendations for research involving human beings contained in Resolution CNE N° 466/2012. RESULTS: Fifty-one subjects (96.2%) had hearing loss, and the conductive type was the most frequent. Only two (3.8%) patients presented bilateral thresholds within normal limits, one with type IV mucopolysaccharidosis and the other with type VI. There were 11 individuals (20.8%) with mucopolysaccharidosis type I with mixed hearing loss, 9 (16.9%) individuals with type I with conductive hearing loss and 9 (16.9%) with type VI with conductive hearing loss. Mild hearing loss was most common (37.3%), followed by moderately severe hearing loss (36.3%). The type B tympanometric curve (80.4%) was the most frequent. CONCLUSIONS: Most of the individuals with mucopolysaccharidosis types I, II, III, IV and VI presented mixed or conductive hearing losses of mild to moderately severe degree, type B tympanograms and an absence of contralateral acoustic reflexes.

ABSTRACT Purpose To evaluate the influence of variables age, educational status and sex in the occurrence of pauses after the standard time in the dichotic sentence identification test. Methods This investigation included 200 right-handed subjects divided into four groups according to age: group I - from 13 to 19 years old, group II - from 20 to 29 years old, group III - from 30 to 39 years old and group IV - from 40 to 49 years old. Each group contained 50 subjects (25 men and 25 women) matched by educational level. The following eligibility criteria was adopted: Brazilian Portuguese mother language, listeners, and fluent readers independent of the educational level. It was applied the dichotic sentence identification test in the steps of binaural integration, directed listening, and it was noted the need for pauses in the test after the standard time. The descriptive and inferential statistics were performed. Results For the binaural integration stages there was a positive association between age and pause occurrence. The educational variable presented a negative association with the occurrence of pauses in all stages of the DSI test. The gender variable showed no association with the occurrence of pause in any of the test steps. Conclusion With increasing age, there is an increase in the incidence of pauses in the binaural integration stages of the test. The more years of study the less chance that the individual will need breaks to perform the test at all stages of presentation. The variable gender did not influence the occurrence of pauses.

Abstract Introduction The registry of the component P1 of the cortical auditory evoked potential has been widely used to analyze the behavior of auditory pathways in response to cochlear implant stimulation. Objective To determine the influence of aural rehabilitation in the parameters of latency and amplitude of the P1 cortical auditory evoked potential component elicited by simple auditory stimuli (tone burst) and complex stimuli (speech) in children with cochlear implants. Method The study included six individuals of both genders aged 5 to 10 years old who have been cochlear implant users for at least 12 months, and who attended auditory rehabilitation with an aural rehabilitation therapy approach. Participants were submitted to research of the cortical auditory evoked potential at the beginning of the study and after 3 months of aural rehabilitation. To elicit the responses, simple stimuli (tone burst) and complex stimuli (speech) were used and presented in free field at 70 dB HL. The results were statistically analyzed, and both evaluations were compared. Results There was no significant difference between the type of eliciting stimulus of the cortical auditory evoked potential for the latency and the amplitude of P1. There was a statistically significant difference in the P1 latency between the evaluations for both stimuli, with reduction of the latency in the second evaluation after 3 months of auditory rehabilitation. There was no statistically significant difference regarding the amplitude of P1 under the two types of stimuli or in the two evaluations. Conclusion A decrease in latency of the P1 component elicited by both simple and complex stimuli was observed within a three-month interval in children with cochlear implant undergoing aural rehabilitation.

Abstract Introduction: Stuttering is a speech fluency disorder, and may be associated with neuroaudiological factors linked to central auditory processing, including changes in auditory processing skills and temporal resolution. Objective: To characterize the temporal processing and long-latency auditory evoked potential in stutterers and to compare them with non-stutterers. Methods: The study included 41 right-handed subjects, aged 18-46 years, divided into two groups: stutterers (n = 20) and non-stutters (n = 21), compared according to age, education, and sex. All subjects were submitted to the duration pattern tests, random gap detection test, and long-latency auditory evoked potential. Results: Individuals who stutter showed poorer performance on Duration Pattern and Random Gap Detection tests when compared with fluent individuals. In the long-latency auditory evoked potential, there was a difference in the latency of N2 and P3 components; stutterers had higher latency values. Conclusion: Stutterers have poor performance in temporal processing and higher latency values for N2 and P3 components.

ABSTRACT Purpose: to obtain and compare the percentage of correct consonants rate in deaf children, cochlear implant or hearing aids users within a twelve-month interval. Additionally, the influence of aspects, such as, frequency in therapy, age at hearing impairment identification and hearing device, were also investigated in the percentage of correct consonants (PCC) index. Methods: nineteen children with hearing impairment, hearing aids or cochlear implant and were in speech therapy participated in this research. The PCC index was calculated using three tests: naming, imitation and spontaneous speech, using the phonology tasks of ABFW’s - Child Language Test. The procedures were applied and reapplied within a 12-month interval, thus, characterizing a longitudinal study. Results: regarding the comparison of the PCC index, there was a statistically significant difference between the applications in all tests. An association of the average gain of percentage of correct consonants with frequency therapy was observed. Conclusion: the PCC index obtained and compared in two occasions, revealed improvement in all tasks after 12 months of speech therapy using aurioral approach. Improvement in oral production and frequency in therapy directly influenced the improvement of oral language development of these children. Improvement in oral language development of these children was directly influenced by compliance to the therapy. The age at hearing loss identification and the daily use of the devices did not influence the PCC indexes.

RESUMO Objetivo: obter e comparar o índice de porcentagem de consoantes corretas em crianças deficientes auditivas, usuárias de Implante Coclear e/ou Prótese Auditiva num intervalo de doze meses. Além disso, buscou-se verificar a influência da frequência em terapia, da época da identificação da deficiência auditiva e do tempo de uso do dispositivo auditivo no índice de PCC. Métodos: participaram desta pesquisa 19 crianças deficientes auditivas, usuárias de Prótese Auditiva e/ou Implante Coclear e que estavam em terapia fonoaudiológica. O índice de porcentagem de consoantes corretas foi calculado por meio de três provas: nomeação, imitação e fala espontânea utilizando as tarefas da prova de fonologia do ABFW - Teste de Linguagem Infantil. Os procedimentos foram aplicados, reaplicados e comparados, num intervalo de 12 meses, caracterizando um estudo longitudinal. Resultados: em relação à comparação do índice de porcentagem de consoantes corretas, houve diferença estatisticamente significante entre as aplicações em todas as provas. Observou-se associação do ganho médio de porcentagem de consoantes corretas apenas com a frequência em terapia. Conclusão: a partir da obtenção e comparação em duas oportunidades do índice PCC em crianças deficientes auditivas, observou-se melhora em todas as tarefas após 12 meses de intervenção fonoaudiológica com a aborgadem aurioral. A melhora do desenvolvimento da linguagem oral destas crianças foi influenciada diretamente pela assiduidade em terapia. A época da identificação da deficiência auditiva e a tempo de uso do dispositivo não influenciaram os índices de PCC.

ABSTRACT The Superior Semicircular Canal Dehiscence Syndrome (SSCDS) is characterized by bone wear layer overlying the superior semicircular canal. Common symptoms of SSCDS the presence of vertigo associated with nystagmus induced by intense sound stimuli or changes in intracranial pressure or middle ear. The aim of this study is to describe the audiological and vestibular findings of two patients diagnosed with Superior Semicircular Canal Deiscence Syndrome, with confirmed diagnosis by computed tomography. Meatoscopy, anamnesis, pure tone audiometry and vocal followed by the acoustic impedance measurements, audiometric Weber, research Tulio phenomenon and Valsalva maneuver, performed by the same researcher in one session were held. Air-bone gap were observed, type A tympanometric curve and acoustic reflex. The air-bone gap is presented with greater amplitude at low frequencies. Hearing complaints were not reported by patients as the first symptoms. Weber showed lateralization in both cases, confirming the presence of gap. The Thulium phenomenon is positive for vertigo in both cases. The Valsalva maneuver showed a change in only one case.

RESUMO A Síndrome da Deiscência do Canal Semicircular Superior (SDCSS) é caracterizada pelo desgaste da camada óssea que recobre o canal semicircular superior. São sintomas comuns da SDCSS a presença de vertigem associada à nistagmos induzidos por estímulos sonoros intensos ou por modificações das pressões intracraniana ou da orelha média. O objetivo deste trabalho é descrever os achados audiólogicos e vestibulares de dois pacientes com diagnóstico de Síndrome da Deiscência do Canal Semicircular Superior, com diagnóstico confirmado por meio de tomografia computadorizada. Foram realizadas meatoscopia, anamnese, audiometria tonal e vocal seguida das medidas de imitância acústica, Weber audiométrico, pesquisa do fenômeno de Túlio e manobra de Valsalva, realizados pela mesma pesquisadora em uma única sessão. Foram observados gap aéreo-ósseo, curva timpanométrica tipo A e reflexos acústicos presentes. O gap aéreo-ósseo apresenta-se com maior amplitude nas frequências baixas. As queixas auditivas não foram relatadas pelas pacientes como os primeiros sintomas. O Weber mostrou lateralização, nos dois casos, confirmando a presença de gap. O fenômeno de Túlio apresentou-se positivo para vertigem em ambos os casos. A manobra de Valsalva apresentou alteração em apenas um caso.
