    (ABORL-CCF Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial, 2007-06-01) Garcia, Vera Lúcia; Pereira, Liliane Desgualdo [UNIFESP]; Fukuda, Yotaka [UNIFESP]; Universidade de São Paulo (USP); Universidade Federal de São Paulo (UNIFESP)
    Selective attention is essential for learning how to write and read. AIM: The objective of this study was to examine the process of selective auditory attention in children with learning disabilities. MATERIAL AND METHOD: Group I included forty subjects aged between 9 years and six months and 10 years and eleven months, who had a low risk of altered hearing, language and learning development. Group II included 20 subjects aged between 9 years and five months and 11 years and ten months, who presented learning disabilities. A prospective study was done using the Pediatric Speech Intelligibility Test (PSI). RESULT: Right ear PSI with an ipsilateral competing message at speech/noise ratios of 0 and -10 was sufficient to differentiate Group I and Group II. Special attention should be given to the performance of Group II on the first tested ear, which may substantiate important signs of improvements in performance and rehabilitation. CONCLUSION: The PSI - MCI of the right ear at speech/noise ratios of 0 and -10 was appropriate to differentiate Groups I and II. There was an association with the group that presented learning disabilities: this group showed problems in selective attention.

    (Associação Brasileira de Otorrinolaringologia e Cirurgia Cervicofacial, 2011-10-01) Porto, Maria Angelica de Almeida [UNIFESP]; Azevedo, Marisa Frasson de [UNIFESP]; Gil, Daniela [UNIFESP]; Medical Specialty Outpatient Unit; Universidade Federal de São Paulo (UNIFESP)
    Accurate information about type, degree, and configuration of hearing loss are necessary for successful audiological early interventions. Auditory brainstem response with tone burst stimuli (TB ABR) and auditory steady-state response (ASSR) exams provide this information. AIM: To analyze the clinical applicability of TB ABR and ASSR at 2 kHz in infants, comparing responses in full-term and premature neonates. MATERIAL AND METHOD: The study was cross-sectional, clinical and experimental. Subjects consisted of 17 premature infants and 19 full-term infants. TB ABR and ASSR exams at 2000 Hz were done during natural sleep. RESULTS: The electrophysiological minimum response obtained with TB ABR was 32.4 dBnHL (52.4 dBSPL); the ASSR minimum was 13.8 dBHL (26.4 dBSPL). The exams required 21.1 min and 22 min, respectively. Premature and full-term infant responses showed no statistically significant differences, except for auditory steady-state response duration. CONCLUSIONS: Both exams have clinical applicability at 2 kHz in infants, with 20 min of duration, on average. In general, there are no differences between premature and full-term individuals.

    (Assoc Brasileira Otorrinolaringologia & Cirurgia Cervicofacial, 2010-05-01) Pereira, Priscila Karla Santana; Azevedo, Marisa Frasson de [UNIFESP]; Testa, Jose Ricardo Gurgel [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    In newborn hearing screening little importance is attributed to changes in the middle ear. Children with secretory otitis in the neonatal period are at risk for developing otitis media in the first year of life.Aim: To determine if children who failed the hearing screening because of conductive hearing loss have more episodes of conductive hearing impairment during their first years of life.Materials and Methods: The study group comprised 62 children who failed the screening for conductive impairment. The control was made up of 221 who passed. Both had audiologic and otolaryngological assistance and were compared regarding the occurrence of conductive disorder. Were used the Fisher's Exact test for statistical analysis and logistic regression models. The study was prospective and retrospective.Results: Children who failed the screening by conductive disorder had more episodes of otitis media during the first year of life than those who did not fail, with statistically significant difference.Conclusion: Infants who failed the screening in the first month of life for conductive alteration are more likely to experience otitis in the first year of life. The high incidence of otitis indicates the need for joint action with otolaryngologist for diagnosis of such changes.

    (Associação Brasileira de Otorrinolaringologia e Cirurgia Cervicofacial, 2012-08-01) Pinheiro, Maria Madalena Canina [UNIFESP]; Dias, Karin Ziliotto [UNIFESP]; Pereira, Liliane Desgualdo [UNIFESP]; Universidade Federal de Santa Catarina Curso de Fonoaudiologia; Universidade Federal de São Paulo (UNIFESP)
    Aging can alter temporal processing and affect speech perception. AIM: To compare temporal processing auditory processing in elderly subject to and new hearing aid users. MATERIALS AND METHODS: The study included 60 elderly patients with bilateral sensorineural hearing loss. The procedures selected were the Duration Pattern Tests (DPT) and gaps in noise (GIN) test were used to analyze the responses of correct identification, and the temporal acuity threshold before and after the fitting of hearing aids. Study design: clinical and experimental research with non-probability sample of convenience. RESULTS: There was no statistically significant difference between the responses from GI and GII individuals. The elderly users of hearing aids had a lower gap detection threshold, greater recognition of gaps and of discrimination of the duration pattern in relation to when they were only potential users. CONCLUSION: There was a deterioration in temporal processing skills, regardless of hearing loss degrees. Thus, the effect of acoustic stimulation by the use of a hearing aid improved resolution and temporal ordering.

    (ABORL-CCF Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial, 2002-05-13) Frota, Silvana [UNIFESP]; Iorio, Maria Cecilia Martinelli [UNIFESP]; UFRJ; Universidade Federal de São Paulo (UNIFESP)
    Introduction: Noise-induced hearing loss is one of the most common causes for sensorineural hearing impairment. Objective: The purpose of this study was to evaluate pure tone and distortion product otoacoustic emissions (DPOAE) pre and post white noise exposition at high levels (100 dB SPL for 10 minutes), considering gender and ear variables, aiming at investigating pure tone audiometry and DPOAE efficiency in detecting subtle temporary threshold shifts (TTS). Study design: prospectivo clinical randomized. Material and method: Forty subjects, 20 male and 20 female ranging from 18 to 36 years old with no otological complaints were evaluated. Pure tone audiometry and DPOAE were carried out pre and post white noise exposure. Results: Pure tone audiometry was sensitive in detecting temporary threshold shifts after white noise exposition in 2, 3 and 4 kHz, with no significant differences concerning gender and ear, whereas DPOAE revealed temporary shifts in audibility evidenced by amplitude reduction, in 2588 and 3614 in female subjects and in 932, 1304, 2588 and 5128 Hz in male subjects. Conclusion: We could conclude that either pure tone audiometry or DPOAE were sensitive in determining significant temporary shifts in hearing thresholds and amplitude, respectively, after white noise exposition, according to the involved frequency range

    AIM: To detect early on a probable hearing loss in children of women exposed to occupational noise during their pregnancy and to verify if there is any difference between the children from those women exposed to occupational noise during their pregnancy and the ones from mothers that do not work under the same conditions. METHODS: Children from women exposed to occupational noise during their pregnancy and children from women who were not exposed were evaluated through distortion product otoacoustic emissions, using the GSI 60 DPOEA SYSTEM equipment and the frequency-ratio F2/F1 equal to 1.2 and the geometric average of 2F1-F2. The intensity of the primary frequencies were kept steady with values of L1=65dBSPL and L2=55dBSPL for F1 and F2, respectively. Student T test in paired samples and independent samples were used. RESULTS: There were no differences in the response amplitude of distortion product otoacoustic emissions between the control and the study groups. There was no statistically difference between male and female children in response amplitude for the two groups aforementioned; and there were no differences between right and left ears from each group. CONCLUSION: We did not observe hearing impairment in children whose mothers were exposed to occupational noise during pregnancy when compared to the children from mothers who were not. There was no difference between the right and left ears, nor between male and female children in each group.

    (Assoc Brasileira Otorrinolaringologia & Cirurgia Cervicofacial, 2013-11-01) Lessa, Alexandre Hundertmarck; Costa, Maristela Julio [UNIFESP]; Universidade Federal de Sergipe (UFS); Universidade Federal de São Paulo (UNIFESP)
    Difficulty understanding speech, particularly in situations unfavorable to communication, is a common complaint among elderly individuals.Objective: to verify the variables connected to hearing loss and stimulus presentation rate and their impact on the speech recognition skills of elderly subjects in quiet and noisy environments.Method: this case-control study included two groups of subjects (31 elderly subjects with normal hearing and 26 with hearing loss) exposed to the List of Sentences in Portuguese and the Slowed List of Sentences in Portuguese tests. Sentence recognition indices were calculated for tests done against noisy and quiet backgrounds at a normal and reduced speech rate. Data sets were submitted to statistical analysis.Results: elderly subjects from both groups had better test results when sentences were played at a slower rate. Statistically significant difference was seen for both groups when the tests were carried out on a quiet background and for the group with hearing loss when tested on a noisy background.Conclusion: regardless of their peripheral hearing, the elderly subjects included in this study were more able to recognize speech when sentences were played at a slower rate against a quiet background. When sentences were played against a noisy background, the elderly subjects with hearing loss had more significant performance improvements than the ones with normal hearing when sentences were played at a slower rate.

    (ABORL-CCF Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial, 2003-03-01) Garcia, Adriana Pontin [UNIFESP]; Iorio, Maria Cecilia Martinelli [UNIFESP]; Petrilli, Antonio Sergio [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    Cisplatin is an antineoplasic drug, which has ototoxicity as a side effect. The goals of this paper were to evaluate the audiological behavior in osteosarcoma patients treated with cisplatin and to verify which evaluation method is the best for early detection of drug induced hearing loss. STUDY DESIGN: Clinical prospective. MATERIAL AND METHOD: 13 patients, that received four cisplatin cycles of 120 mg/m²/cycle divided in two days (60 mg/m²/day), were evaluated prior to start of chemotherapy, prior to each scheduled course and at the end of treatment. It was performed the pure tone audiometry (250 to 18000 Hz) and the transitory and distortion product otoacoustic emission (TOAE and DPOAE). RESULTS: In the mean values, it was observed hearing loss, after 480 mg/m² cumulative cisplatin dosage, beginning at 8 kHz. At the individual values, it was observed that 15,3% had mild to moderate hearing loss beginning at 3kHz, 15,3% beginning at 4 kHz, 15,3% beginning at 6 kHz and 15,3% beginning at 8 kHz. TOAE did not show changes before the audiometry. DPOAE showed smaller amplitude after the cycles of cisplatin, but this change happened together with the audiometry - not prior. CONCLUSION: The high frequency audiometry was more efficient to detect early ototoxicity. TOAE and DPOAE can be used as complement tests. All cisplatin exposed patients showed high frequency hearing loss, 30,6% showed hearing loss in important frequencies (3 and 4 kHz) for speech comprehension.

    (Assoc Brasileira Otorrinolaringologia & Cirurgia Cervicofacial, 2011-03-01) Sa, Cintia Ishii de; Pereira, Liliane Desguado [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    Exposure to music may be useful in the P300 retest and avoid habituation.Aim: To verify the influence of the exposure to different kinds of music in P300 in young females.Study design: Clinical prospective.Material and Method: Forty-five women aged from 20 to 36 years were evaluated. P300 was studied before and after musical stimulation with different rhythms. Brazilian songs, international songs, and classical music melodies were selected. Each song had its velocity altered and was named as fast and slow. Subjects were divided into 2 groups exposed to music: one group was exposed to the fast version and the other to the slow version. The control group not exposed to music and was evaluated within the same time period of the others.Result: There were statistically significant differences when comparing P300 amplitude in the first and third stimulation with the comparison group.Conclusion: In the same subject, several sequential registrations of P300 caused habituation, which was not seen during exposure to music before P300 recording. Exposure to music at preset different velocities did not affect the P300 in young females.

    (Fundação Otorrinolaringologia, 2011-09-01) Camboim, Elizângela Dias [UNIFESP]; Scharlach, Renata Coelho [UNIFESP]; Farias, Kelvânio Vitório De; Oliveira, Lívia Karla Gadêlha De; Vasconcelos, Dênis; Azevedo, Marisa Frasson de [UNIFESP]; Universidade Federal de São Paulo (UNIFESP); Universidade Estadual de Ciências da Saúde de Alagoas Faculdade de Fonoaudiologia de Alagoas
    INTRODUCTION: The transient-evoked otoacoustic emissions (TEOAE) have been the most widespread technique to perform neonatal hearing screening. Scrutinizing their measures by way of an association with other alterations that may impair the infant's auditory system is important. OBJECTIVE: Analyze the incidence and the response levels of the transient-evoked otoacoustic emissions on infants having a physiological gastroesophageal reflux disease (GERD). METHOD: A prospective study was performed at Santa Juliana Hospital's Otorhinolaryngology Department. 118 prematurely-born and timely-born babies, from newly-born to 6 months old, who were sent by pediatricians and gastropediatricians, participated in the study and they were divided into two groups: Study Group: 63 infants clinically diagnosed of a physiological gastroesophageal reflux disease, and Control Group: 55 infants without a physiological gastroesophageal reflux. The peripheral hearing function was evaluated by both transient-evoked otoacoustic emissions and otoscopy examinations performed by an otorhinolaryngologist. RESULTS: The average response levels of the transient-evoked otoacoustic emissions were higher in the non-reflux group for frequency bands of 2kHz, 2. 5kHz, 3kHz, 3. 5kHz and 4. 5kHz bilaterally, with a statistically significant difference, achieving the average values of 7. 71dB and 7dB in the right ear found in the frequency bands of 2 and 4kHz, respectively. CONCLUSION: There was a lower incidence and a lower response level of the transient-evoked otoacoustic emissions in physiological gastroesophageal reflux children in comparison with children having no reflux.

    As the age advances, the number of chronic diseases also grows, the systemic arterial hypertension (SAH) and hearing loss having a significant prevalence in aged people. OBJECTIVE: To compare and analyze anamnesis and threshold tonal audiometry results in both hypertensive and non-hypertensive patients. STUDY DESIGN: Transversal contemporany cohort study. MATERIAL AND METHOD: This study has been conducted at UNIFESP in the period from March to November 2003. Seventy people in the age group from 60 to 92 - 15 male and 54 female - were evaluated through anamnesis and threshold tonal audiometry. RESULTS: As to audiology findings of groups studied, a difference can be noted regarding ramp-typed audiometric configuration and buzz claim, both occurring most frequently in non-hypertensive aged people. CONCLUSION: Hypertensive aged people did not present a higher hearing deficit, the degree of hearing loss being similar in both groups. Prevailing audiometric configuration in hypertensive group was that of full-type, while the non-hypertensive group presented a ramp-typed configuration. As to audiologic claims, the non-hypertensive group presented an increased occurrence of buzz claim.

    (ABORL-CCF Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial, 2009-02-01) Angrisani, Rosanna Mariangela Giaffredo; Azevedo, Marisa Frasson de [UNIFESP]; Pereira, Liliane Desgualdo [UNIFESP]; Lopes, Celso [UNIFESP]; Garcia, Michele Vargas [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    Vitiligo is a skin disease characterized by absence of melanin due to melanocytes destruction. AIM: to study the incidence of hearing alterations in patients with vitiligo. METHOD: prospective audiological evaluation, transient-evoked otoacoustic emission recordings and study the effects of suppression in 24 patients with vitiligo. Their ages ranged from 15 to 45 years. RESULTS: 21 patients (87.5%) had normal audiometry; 2 had unilateral hearing loss in the high frequencies and 1 had cochlear moderate hearing loss in the left ear. Of these 21 subjects, 66.7% had no otoacoustic emissions, suggesting cochlear dysfunction. Only 7 patients had otoacoustic emissions present in all frequencies (29.2%) and 17 (70.8%) did not have them, and the highest rate of no otoacoustic emissions happened in the right ear of males. Regarding the suppression study, 6 subjects failed, all of them were females, and their left ears were the most affected. CONCLUSION: the findings show that patients with vitiligo, particularly males, have a greater predisposition to cochlear dysfunction, especially in the right ear. As far as the suppression effect was concerned, there was a greater alteration in the female efferent system, particularly in the left ear. Hearing alterations did not vary as far as age is concerned, type of vitiligo and time of disease progression.

    Presbyacusis is a hearing loss combined with functional auditory decline due to the aging process. AIM: The aim of this study is to characterize verbal and nonverbal sound interaction aspects in elderly individuals with and without hearing loss by means of Binaural Fusion Test, Sound Localization Test at five directions and Pediatric Sentence Identification (PSI), taking into consideration each procedure and hearing loss magnitude. STUDY DESIGN: Clinical study with transversal cohort. MATERIAL AND METHOD: A number of 110 elderly individuals, aged between 60 to 85 years, with normal hearing and with symmetric neurossensorial hearing loss up to moderately severe hearing impairment participated in this study. The common auditory behavior for all the selected tests was nominated as interaction. The analysis was performed by means of a single procedure and also based on audiometric magnitude. RESULTS: There were more individuals that failed the Binaural Fusion Test. The procedures that showed significant statistical dependency on the audiometric magnitude groups were Sound Localization Test, Temporal Lateralization Test and PSI-MCI (-10) Test. CONCLUSION: Elderly individuals present difficulty in the binaural interaction process when the auditory information is not complete. The magnitude of the hearing loss interfered specially in the localization auditory behavior.

    Temporal epilepsy, one of the most common presentation of this pathology, causes excessive electrical discharges in the area where we have the final station of the auditory pathway. Both the anatomical and functional integrity of the auditory pathway structures are essential for the correct processing of auditory stimuli. AIM: to check the Auditory Processing in patients with temporal lobe epilepsy regarding the auditory mechanisms of discrimination from sequential sounds and tone patterns, discrimination of the sound source direction and selective attention to verbal and nonverbal sounds. METHOD: eight individuals with temporal lobe epilepsy were assessed, after excluding those with non-confirmed diagnosis or with the focus of discharges not limited to this lobe. The evaluation was carried out through special auditory tests: Sound Localization Test, Duration Pattern Test, Digits Dichotic Test and Non-Verbal Dichotic Test. Their performances were compared to the performances of individuals without neurological diseases (case-control study). RESULTS: similar performances were observed between patients with temporal lobe epilepsy and the control group regarding the auditory mechanism of sound source direction discrimination. Comparing the other auditory mechanisms assessed, the patients with temporal lobe epilepsy presented worse results. CONCLUSION: individuals with temporal lobe epilepsy had more deficits in auditory processing than those without cortical damage.

    Implementing rehabilitation programs to hearing impaired adults is of great importance, mainly in the elderly population, and it is necessary to add them to the routine of outpatient care programs. AIM: to present a group care program for elderly patients who are fitted with hearing aids. MATERIAL AND METHOD: to carry out a pilot study of clinical and experimental type, with the participation of 40 elderly users of hearing aids donated by the government, distributed within six groups, with maximum of eight participants jointly with their respective companions. Program consisted of three meetings every fifteen days, where information and education on the proper use hearing aids was transmitted. RESULTS: Most of the patients participated actively in the meetings spontaneously giving their opinion or answering questions when so requested. All elderly had been informed as to the importance of accepting their auditory deficiency and on the need to be motivated towards using hearing aids. Moreover, listening to depositions of other elderly users seemed to facilitate understanding of their own difficulties and stimulated them in the process of getting used to the sound amplification. CONCLUSION: Groups structure facilitated interaction among aged ones, helping them to clarify communication doubts and strategies and, consequently, it promoted their adaptation.

    Teste sun “speech understanding in noise” em português
    (Universidade Federal de São Paulo (UNIFESP), 2014-07-31) Cruz, Nara Vaez Goncalves da [UNIFESP]; Pereira, Liliane Desgualdo Pereira [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    INTRODUCTION: Age-related hearing loss is a common health problem for middle-aged and for older adults. Hearing disability has important implications for the quality of life. Yet, hearing impairment in adults is still largely underdetected and undertreated. Opportunistic hearing screening programs are a powerful way to raise awareness of the importance of hearing surveillance, to improve knowledge about hearing loss and rehabilitation options. Some studies shows that hearing programs should focus on the difficulties experienced by the people with a hearing problem, what includes difficulties in challenging listening situations. In order to target this aim, the Speech Understanding in Noise test (SUN Test) was developed by the CNR National Research Council of Italy, Institute of Electronics, Computer and Telecommunication Engineering IEIIT, Milano, Italy. The SUN test (Speech Understanding in Noise) consists of a list of intervocalic consonants in noise presented in a multiple choice paradigm by means of a touch screen. OBJECTIVE: Development of the SUN Test in Portuguese brazilian version. METHODS: this novel test was developed through three steps: developing the building blocks (speech stimuli, noise); defining the list of stimuli and the associated noise settings; and optimizing the test outcomes in a population of adults with varying degrees of hearing impairment and handicap. RESULTS: The list of stimulus was developed, the noise-level for each vowel-consonant-vowel was measured to define an appropriate signal-to-noise ratio and the test outcomes provides one out of three possible results in a self-explanatory way: ‘a hearing check is recommended’ (red light), or ‘a hearing check would be advisable’ (yellow light), or ‘no hearing difficulties’ (green light) CONCLUSION: the test of Suprathreshold Acuity in Noise in Brazilian Portuguese was developed.

    Transient otoacustic emissions with tone pip in individuals with sensorineural hearing loss
    (Associação Brasileira de Otorrinolaringologia e Cirurgia Cervicofacial, 2011-10-01) Takeda, Thays Bueno; Gil, Daniela [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)
    Otoacoustic Emissions are generated by the cochlea in response to sound stimuli. They can be generated by clicks or specific frequency stimuli, such as tone pips. This is a quick and objective test with several applications. OBJECTIVE: To investigate the influence of the type of stimulus achieving otoacoustic emissions in individuals with mild and moderate sensorineural hearing loss of sloping configuration. MATERIAL AND METHOD: Thirty-two male and female patients aged from 17 to 63 years, with symmetric sensorineural hearing loss with a sloping configuration were evaluated. All subjects underwent transient otoacoustic emissions testing elicited by clicks and 2.000Hz and 4.000Hz tone pips. RESULTS: The degree of hearing loss and gender influenced otoacoustic emissions; it was significant for click stimulus and tone pips at 2.000Hz. Emissions were absent more often in females with both procedures. CONCLUSIONS: Otoacoustic emissions evoked with clicks coincided with the emissions of tone pips at 2.000Hz. Tone pips at 4.000Hz were more sensitive than clicks for detecting impairment in individuals with high frequencies hearing loss. Gender and the degree of hearing loss ere factors that affected OAE registration.

    Tympanometry with 226 and 1000 Hertz tone probes in infants
    (Assoc Brasileira Otorrinolaringologia & Cirurgia Cervicofacial, 2012-01-01) Resende, Luciana Macedo de [UNIFESP]; Ferreira, Juliana dos Santos; Silva Carvalho, Sirley Alves da; Oliveira, Isamara Simas; Bassi, Iara Barreto; Universidade Federal de Minas Gerais (UFMG); Universidade Federal de São Paulo (UNIFESP)
    This study aimed at describing and analyzing tympanometric results obtained with 226Hz and 1000Hz probe tones; checking for correlations between tympanometry, otoacoustic emissions and otoscopic examination; describing abnormal results found in the evaluation procedures.Methods: Double-blind and prospective study. Our sample included 70 babies, between 7 days and one month and 13 days of age, without risk indicators for hearing loss, evaluated in the State Neonatal Hearing Screening Program. Transient evoked otoacoustic emissions, otoscopic examination and tympanometry with 226Hz and 1000Hz probe tones were used as assessment tools. The study was approved by the Ethics Committee from the institution.Results: Statistically significant differences were observed (p<0.05) in the tympanometric measures correlation and also between transient evoked otoacoustic emissions and compliance obtained with both probe tones. Most test results were within the normal range (94.28%). Three children (4.28%) were referred to diagnostic follow-up and one (1.42%) had middle ear dysfunction confirmed by otoscopy and 1000Hz tympanometry.Conclusions: 1000Hz tympanometry is the most reliable probe tone used to evaluate children under three months of age. More studies focusing on middle ear acoustics and mechanics are necessary to provide reliable and precise interpretation in the evaluation of middle ear functions in babies.
