- Reflectância de banda larga em recém-nascidos com presença de emissões otoacústicas evocadas por transiente(2013) SILVA, Kilza Arruda de Lyra e; UROSAS, Juliana Granja; SANCHES, Seisse Gabriela Gandolfi; CARVALLO, Renata Mota MamedePURPOSE: To characterize the normal values of acoustic energy reflectance obtained with pure-tone stimulation in neonates prior to hospital discharge. METHODS: Seventy-seven infants (37 girls and 40 boys) were evaluated by measuring acoustic reflectance using pure-tone stimuli, transient-evoked otoacoustic emissions, and tympanometric probe frequencies of 226 Hz and 1 kHz. RESULTS: At low frequencies (258-750 Hz), greater energy reflectance was observed, while at medium frequencies (1-3 kHz), greater energy absorption was observed. There was no difference between ears or between genders. CONCLUSION: Normal energy reflectance values were obtained for the studied population. The data indicate a reflectance curve with a distinct configuration for the studied age.
- Caracterização eletrofisiológica da audição em prematuros nascidos pequenos para a idade gestacional(2013) ANGRISANI, Rosanna Mariangela Giaffredo; AZEVEDO, Marisa Frasson de; CARVALLO, Renata Mota Mamede; DINIZ, Edna Maria de Albuquerque; FERRARO, Alexandre Archanjo; GUINSBURG, Ruth; MATAS, Carla GentilePURPOSE: To characterize the Auditory Brainstem Response (ABR) of small for gestational age preterm newborns and to compare the findings to those of appropriate for gestational age premature newborns in order to verify whether the small for gestational age condition is a risk factor for hearing loss. METHODS: This prospective cross-sectional multicenter study evaluated 72 preterm newborns of both genders (35 small and 37 appropriate for gestational age), who were born at 30 to 36 weeks of gestational age and were evaluated before hospital discharge. Only newborns with present transient evoked otoacoustic emissions and tympanometry type A were included. The ABR was performed with click stimuli. The quantitative data analysis was performed using mean and standard deviation measures for each group. For qualitative analysis, the ABR results were classified as normal or altered according to the absolute latencies of waves I, III, V and interpeaks I-III, III-V, I-V. The analysis was carried out considering the age of the newborn at the time of examination. RESULTS: Alterations were evident in 32 newborns (44.44%), being 15 small (43%) and 17 appropriate for gestational age (46%), with no between-groups difference. Of the 15 small for gestational age newborns with altered ABR, six presented as auditory risk only the small for gestational age condition. In the group of adequate for gestational age newborns, there was a higher occurrence of alteration in males. CONCLUSION: There was no difference in responses of auditory evoked potential between small and appropriate for gestational age preterm newborns. Therefore, the condition does not behave as a risk factor for retrocochlear impairment.
- Medidas de reflectância acústica na otosclerose: estudo de caso(2014) NETO, Letícia Cortez; CIBIN, Bruna Carla; CARVALLO, Renata Mota Mamede; SANCHES, Seisse Gabriela GandolfiThis research aimed to analyze the reflectance measurements in a patient with otosclerosis. The patient, female, 51 years old; she complained of bilateral hearing loss and had a diagnosis hypothesis of otosclerosis. The following audiological tests were performed in both ears: tympanometry, pure-tone audiometry, and speech audiometry tests and acoustic reflectance measurements. Through acoustic wideband reflectance analysis, it was possible to observe an increase in reflectance, such as is seen in otosclerotic ears, between the frequencies of 500 Hz and 1500 Hz and to differentiate the left and right ear. Acoustic reflectance measurements have the potential to yield results that allow the differentiation between the two ears; thus, the use of the wideband acoustic reflectance is suggested as a part of the otosclerosis diagnostic procedure.
- Avaliação auditiva periférica em crianças com síndrome de Down(2014) CARRICO, Barbara; SAMELLI, Alessandra Giannella; MATAS, Carla Gentile; MAGLIARO, Fernanda Cristina Leite; CARVALLO, Renata Mota Mamede; LIMONGI, Suelly Cecília Olivan; NEVES-LOBO, Ivone FerreiraPurpose This study sought to characterize the peripheral auditory system of individuals with Down syndrome (DS) using conventional and high-frequency audiometry. Methods We performed a cross-sectional and observational study. Fifteen individuals with DS, who were of both genders and between 7 and 15 years of age, participated in this study. The following procedures were performed: otoscopy, tympanometry with ipsilateral and contralateral acoustic reflex, pure-tone audiometry, vocal audiometry and high-frequency audiometry. Results There was a predominance of mild conductive hearing loss in one or both ears. The mean hearing thresholds for conventional audiometry were below 20 dB HL and between 20 and 40 dB HL for high-frequency audiometry. The Pearson correlation coefficient indicated a moderate positive correlation between the 9-14 kHz thresholds and age. Conclusion Overall, no significant differences were observed when comparing the right and left ears of individuals with DS, in regards to pure-tone audiometry, immittance testing and speech audiometry. Most children showed middle ear abnormalities and conductive hearing loss. Moreover, high-frequency audiometry suggested the onset of impaired cochlear function, which may be associated with frequent otitis media episodes and/or early cochlear degeneration.
- Processamento temporal de crianças com transtorno fonológico submetidas ao treino auditivo: estudo piloto(2012) VILELA, Nadia; WERTZNER, Haydée Fiszbein; SANCHES, Seisse Gabriela Gandolfi; NEVES-LOBO, Ivone Ferreira; CARVALLO, Renata Mota MamedePURPOSE: This study compared the temporal processing performance of children with phonological disorders submitted to formal and informal auditory training. METHODS: Fifteen subjects with phonological disorder (pure tone thresholds ≤20 dBHL from 0.50 to 4 kHz, and age between 7 years and 10 years and 11 months) were evaluated, divided into three groups: Control Group: five subjects (mean age 9.1 years) without auditory processing disorder, who passed through two evaluations of the auditory processing at intervals of six to eight weeks and without any intervention; Formal Training Group with five subjects (average 8.3 years) with auditory processing disorder submitted to eight sessions of formal training; and Informal Training Group, with five subjects (average 8.1 years) with auditory processing disorder submitted to eight sessions of informal training. RESULTS: After eight sessions the formal training group showed an improvement of 8% and the informal training group of 22.5% in comparison with the pitch pattern sequence test. For the duration pattern sequence test, the average of the formal training group improved by 12.9% and the informal training group by 18.7%. There was no statistical difference between the means obtained by both groups after intervention, neither in the pitch pattern nor in the duration pattern sequence test. CONCLUSION: Although the results did not present significant differences, this pilot study suggests that both formal and informal trainings provide improvement in the temporal processing abilities of children with phonological and auditory processing disorders.
- Peripheral hearing in Parkinson's disease: a systematic review(2023) LEME, Mariana S.; SANCHES, Seisse G. G.; CARVALLO, Renata M. M.Objective To investigate the implications of Parkinson's disease (PD) in the peripheral auditory system, a systematic survey of the scientific literature was conducted. Design Systematic review. Study sample An electronic search of the non-gray literature in the last decade was conducted using the digital databases MEDLINE (R) (PubMed interface), LILACS (R) (Virtual Health Library), Web of Science (R) (CAPES publications portal), and SciELO (R). Studies addressing peripheral auditory function as part of the range of nonmotor PD symptoms were selected for analysis. Results Pure tone audiometry data suggested that sensorineural hearing loss was more severe in the PD population than in the control groups. The effects of PD on cochlear function were evidenced by a decrease in the levels of otoacoustic emissions. Conclusions Sensorineural hearing loss and cochlear impairment are more severe in the PD population than in the control groups. Additional studies are recommended to further understand the characteristics of the peripheral auditory system in PD patients, which constitutes an emerging subject in the scientific literature.
- Psychoacoustic analyses of cochlear mechanisms in tinnitus patients with normal auditory thresholds(2014) BUZO, Byanka Cagnacci; CARVALLO, Renata Mota MamedeObjective: Tinnitus is often related to auditory dysfunction. We hypothesised that, among individuals with normal auditory thresholds, the mechanism of frequency selectivity might differ between subjects with and without tinnitus. Our objective was to identify any differences between normal-hearing individuals with tinnitus and those without in terms of psychophysical tuning curves (PTCs) and threshold-equalising noise (TEN) test results. Design: We determined PTCs and performed the TEN test. Study sample: We evaluated 57 individuals, 16 with bilateral tinnitus (tinnitus-group) and 41 without tinnitus (control-group). Results: We found significant differences between tinnitus and control groups regarding the following: 2 kHz PTCs obtained in noise at 6 and 8 kHz; 4 kHz PTCs obtained in noise at 2 and 8 kHz; and 6 and 8 kHz PTCs obtained in noise at 2 and 3 kHz. The TEN test revealed differences between groups in terms of auditory thresholds, which were significantly higher in the tinnitus group. In addition, none of the individuals in the tinnitus group were found to have dead regions in the cochlea. Conclusions: Despite having normal auditory thresholds, individuals with tinnitus have auditory patterns that differ significantly from those seen in individuals without tinnitus, such differences being suggestive of cochlear impairment.
article 1 Citação(ões) na Scopus Distortion-product otoacoustic emissions at ultra-high frequencies in parents of individuals with autosomal recessive hearing loss(2014) MELLO, Jaqueline Medeiros de; DELLA-ROSA, Valter Augusto; CARVALLO, Renata Mota MamedePurpose: To evaluate the cochlear function of parents of individuals with autosomal recessive gene Gap Junction Protein Beta-2 hearing loss by ultra-high frequencies distortion-product otoacoustic emissions (DPOAEs), compared with responses of a control group matched for age and gender. Methods: We studied 56 subjects aged from 20 to 58 years, divided into two groups. The study group comprised 28 parents of hearing-impaired patients due to autosomal recessive inheritance, 14 females aged 20.0-55.0 years (mean 32.8 years) and 14 males aged 20.0-58.0 years (mean 35.2 years). Control group was composed of normal hearing individuals, 14 males and 14 females age-matched to the study group. The subjects underwent tests for audiometry, tympanometry, and DPOAE in the frequency range of 9.000-16.000 Hz. Results: We found 64.3% of normal results of DPOAE in the study group compared to 91.1% in the control. There were significant differences between groups in the ears and DPOAE responses, and the mean level of response was in 10 dBNPS in study group and 14 dBNPS in the control. The Pearson's correlation between age and DPOAE in ultra-high frequencies showed no statistical significance. Conclusion: DPOAE at ultra-high frequencies were able to identify individuals from both groups, suggesting that heterozygous individuals for the Gap Junction Protein Beta-2 gene mutation may have damage to the cochlear function before clinical manifestation in audiometry.- Electrophysiological study of hearing in full-term small-for-gestational-age newborns(2012) ANGRISANI, Rosanna Mariangela Giaffredo; AZEVEDO, Marisa Frasson De; CARVALLO, Renata Mota Mamede; DINIZ, Edna Maria de Albuquerque; MATAS, Carla GentilePURPOSE: To describe the Brainstem Auditory Evoked Potential (BAEP) results of full-term small-for-gestational-age newborns, comparing them to the results of full-term appropriate-for-gestational-age newborns, in order to verify whether the small-for-gestational-age condition is a risk indicator for retrocochlear hearing impairment. METHODS: This multicentric prospective cross-sectional study assessed 86 full-term newborns - 47 small- (Study Group) and 39 appropriate-for-gestational-age (Control Group - of both genders, with ages between 2 and 12 days. Newborns with presence of transient evoked otoacoustic emissions and type A tympanometry were included in the study. Quantitative analysis was based on the mean and standard deviation of the absolute latencies of waves I, III and V and interpeak intervals I-III, III-V and I-V, for each group. For qualitative analysis, the BAEP results were classified as normal or altered by analyzing these data considering the age range of the newborn at the time of testing. RESULTS: In the Study Group, nine of the 18 (38%) subjects with altered BAEP results had the condition of small-for-gestational-age as the only risk factor for hearing impairments. In the Control Group, seven (18%) had altered results. Female subjects from the Study Group tended to present more central alterations. In the Control Group, the male group tended to have more alterations. CONCLUSION: Full-term children born small or appropriate for gestational age might present transitory or permanent central hearing impairments, regardless of the presence of risk indicators.
- Audiological and electrophysiological assessment of professional pop/rock musicians(2012) SAMELLI, Alessandra G.; MATAS, Carla G.; CARVALLO, Renata M. M.; GOMES, Raquel F.; BEIJA, Carolina S. de; MAGLIARO, Fernanda C. L.; RABELO, Camila M.In the present study, we evaluated peripheral and central auditory pathways in professional musicians (with and without hearing loss) compared to non-musicians. The goal was to verify if music exposure could affect auditory pathways as a whole. This is a prospective study that compared the results obtained between three groups (musicians with and without hearing loss and non-musicians). Thirty-two male individuals participated and they were assessed by: Immittance measurements, pure-tone air conduction thresholds at all frequencies from 0.25 to 20 kHz, Transient Evoked Otoacoustic Emissions, Auditory Brainstem Response (ABR), and Cognitive Potential. The musicians showed worse hearing thresholds in both conventional and high frequency audiometry when compared to the non-musicians; the mean amplitude of Transient Evoked Otoacoustic Emissions was smaller in the musicians group, but the mean latencies of Auditory Brainstem Response and Cognitive Potential were diminished in the musicians when compared to the non-musicians. Our findings suggest that the population of musicians is at risk for developing music-induced hearing loss. However, the electrophysiological evaluation showed that latency waves of ABR and P300 were diminished in musicians, which may suggest that the auditory training to which these musicians are exposed acts as a facilitator of the acoustic signal transmission to the cortex.
