- Peripheral and central auditory assessment in among the elderly(2016) SAMELLI, Alessandra Giannella; MATAS, Carla Gentile; RABELO, Camila Maia; MAGLIARO, Fernanda Cristina Leite; LUIZ, Natália Paião; SILVA, Lidiane DiasAbstract Introduction: Presbycusis can affect different portions of the auditory system, causing impacts of varying degrees of seriousness on the daily routine of elderly persons. It is essential that the extent of the deficit as well as the degree of handicap is evaluated, so that the hearing of the elderly can be effectively rehabilitated, improving their quality of life. Purpose: To characterize the peripheral and central hearing of elderly individuals and assess their auditory handicaps. Methods: A cross sectional observational study was performed. We evaluated 83 elderly persons (60-85 years; 33 men, 50 women) with normal hearing or sensorineural hearing loss. Individuals were divided into 3 groups according to the 3 to 6kHz hearing thresholds: G1 - mean of 0 to 39 dBHL (80 ears); G2 - mean of 40 to 59 dBHL (48 ears); G3 - mean of 60 to 120dBHL (38 ears). All individuals responded to the Hearing Handicap Inventory for the Elderly (HHIE), and underwent Pure Tone Audiometry, Auditory Brainstem Response (ABR) and Long Latency Response (P300) evaluation. Results: Men had higher auditory thresholds at frequencies from 500 to 12,000Hz (with a statistical difference between 2-8 kHz) and also significantly greater latencies for ABR components. There was no difference between genders for the P300 evaluation. Comparison between groups showed: a statistically significant difference for age; greater ABR wave latencies and interwave intervals; that questionnaire scores worsened as hearing threshold declined; and similar P300 latencies. Conclusions: Elderly people have impairment throughout the auditory pathway (peripheral and central). The P300 was less accurate at identifying the losses that come with age. The HHIE demonstrated negative effects on the social life of elderly people, agreeing with the hearing thresholds found.
- Audiological and electrophysiological assessment of professional orchestral musicians(2020) SAMELLI, Alessandra Giannella; RABELO, Camila Maia; SILVA, Liliane Aparecida Fagundes; GONZAGA, Denise; SANTIAGO, Joyce Miranda; MAGLIARO, Fernanda Cristina Leite; MATAS, Carla GentileABSTRACT Purpose: to verify whether the frequent musical exposure can impair peripheral and central auditory pathway responses in professional orchestral musicians. Methods: 45 male individuals from 19 to 40 years old participated in the study. They were divided into two groups: one comprising 30 orchestral musicians who played strings or wind instruments, and another with 15 nonmusicians. The two groups were submitted to both conventional and high-frequency pure-tone audiometry, transient-evoked otoacoustic emissions, and frequency-following response. The results were subjected to descriptive and inferential statistical analysis, using the one-way ANOVA unmatched samples parametric test, with a 5% significance level. Results: no significant differences were observed between the hearing thresholds in both conventional and high-frequency audiometry and frequency-following response. However, there were statistically significant differences between transient-evoked otoacoustic emission responses, with lower responses to musicians in comparison to the nonmusician group. Conclusion: the results suggest that frequent musical exposure experienced by orchestral musicians can impair the cochlear hair cells’ function. Therefore, audiological monitoring is important to detect subclinical impairments.
- Potenciais evocados auditivos de longa latência em campo sonoro em crianças audiologicamente normais(2015) MATAS, Carla Gentile; SILVA, Fernanda Bicalho Lima; CARRICO, Barbara; LEITE, Renata Aparecida; MAGLIARO, Fernanda Cristina LeitePurpose: To characterize the Long-Latency Auditory Evoked Potentials (LLAEP) (P1, N1, P2, N2, P300) with acoustic stimuli presented in sound field system in children with normal hearing, as well as to verify the stability of these potentials. Methods: This prospective, longitudinal study comprised 17 children with ages between 6 and 13 years and hearing thresholds within normal. The LLAEP P1, N1, P2, N2, P300 were recorded with speech stimuli and tone burst presented in sound field system, in three different moments: initial assessment (M0), three months after the initial assessment (M3), and nine months after the initial assessment (M9). Results: When the speech stimuli was used, there was a decrease in the latency values of components P1 (M0xM3/M0xM9/M0xM3xM9) and P2 (M0xM9), as well as an increase in the amplitude of P300 (M0xM3) over time. With the tone bust stimuli, it was verified a decrease in the latency values of P300 (M0xM9) over time. Conclusion: it was possible to identify the components of the LLAEP in most individuals. The P1, N1, P2, N2 (tone burst) and N1 and N2 (speech) did not change their latencies and amplitudes between the different moments of evaluation, suggesting stability of this potential in the period of 9 months. The P300 was the component most sensitive to the time intervals considered, since it presented modifications over time that indicated maturation of the central auditory nervous system. The latencies of all components obtained with speech stimulus were higher than with tone bursts, indicating that different stimuli generate different cortical responses.
- 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.
