PURPOSE To analyze the findings for Evoked Otoacoustic Emissions (EOEA) and suppression effect in workers with normal hearing exposed to pesticides and noise . METHODS The sample consisted of 55 participants with normal hearing, with ages ranging from 18 to 35 years, divided into two groups: one group exposed to noise and pesticides (GRA) and a control group (CG). The GRA was composed of 25 p...

PURPOSE To verify whether children with phonological disorders present alterations in the medial olivocochlear system. METHODS This is a prospective cross-sectional study in which 19 normal hearing children of both genders, with ages between 4 and 7 years, were divided into two groups: 11 children without phonological disorders (control group) and eight with phonological disorders (study grou...

UNLABELLED 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...

Background Type 1 neurofibromatosis occurs in every 3,000 individuals, representing 90% of cases neurofibromatosis. Hearing impairments are not commonly described as an alteration resulting from the pathology; however, sensorineural hearing losses with retrocochlear characteristics may occur a result presence acoustic neurinomas. Objectives To assess electrophysiological and electroacoustic ind...

The objectives of the study were to demonstrate hearing status in newborns at first screening by Transient Evoked Otoacoustic Emissions and to find out the relationship between abnormal hearing screening and known risk factors. This study was conducted in the department of neonatology of Bangabandhu Sheikh Mujib Medical University in collaboration with department of otolaryngology and departmen...

INTRODUCTION Early diagnosis of hearing loss minimizes its impact on child development. We studied factors that influence the effectiveness of screening programs. OBJECTIVE To investigate the relationship between gender, weight at birth, gestational age, risk factors for hearing loss, venue for newborn hearing screening and "pass" and "fail" results in the retest. METHODS Prospective cohort...

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...

Hyperbilirubinemia at neonatal period is one of the major deteriorating factors of the auditory system. If left untreated, it may cause certain cerebral damage. This study aims to evaluate the impact of hyperbilirubinemia on the hearing of neonate. This study was conducted on 35 newborn babies with jaundice (bilirubin more than 20 mg/dL). Auditory brainstem response (ABR) and transient evoked o...
