OBJECTIVE To determine whether there is any influence of systemic arterial hypertension on the peripheral auditory system. METHODS This was a cross-sectional study that investigated 40 individuals between 30 and 50 years old, who were divided into groups with and without systemic arterial hypertension, using data from high-frequency audiometry, transient-evoked otoacoustic emissions and disto...

UNLABELLED Transient evoked otoacoustic emissions and distortion product otoacoustic emissions have gained significant importance in the identification of cochlear alterations. AIM To record distortion product thresholds through the monitoring of otoacoustic emissions in normal conditions and in the presence of electrophysiologic changes in cochlear outer hair cells in sheep after hyperinsuli...

UNLABELLED School learning can be hampered if there are defects on the central auditory process. Since those with auditory deficiency can be rehabilitated, it is fundamental that we identify them. Otoacoustic emissions test has low cost and operational ease. STUDY DESIGN clinical and experimental. AIM to study the relationship between school learning and transient otoacoustic emission suppr...

introduction: hearing is essential for humans to communicate with one another. early diagnosis of hearing loss and intervention in neonates and infants can reduce developmental problems. the aim of the present study was to assess the prevalence of hearing impairment in newborns admitted to a neonatal intensive care unit (nicu) and analyze the associated risk factors.   materials and methods: th...

OBJECTIVE To evaluate the effects of perinatal asphyxia on the level of the response to transient otoacoustic emissions in infants. METHODS Otoacoustic emissions in 154 neonates were performed: 54 infants who suffered asphyxia at birth, measured by Apgar score and medical diagnosis, and 100 infants without risk were compared. Scores less than 4 in the first minute and/or less than 6 in the fi...
