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...

The audiologic diagnosis of pseudohypacusis continues to challenge the clinical audiologist. The introduction of otoacoustic emissions (OAEs) to the test repertoire of the audiologist may prove valuable in the evaluation of pseudohypacusis. This report highlights five cases in which transient evoked otoacoustic emissions (TEOAEs) were used to cross-check the validity of subjective audiologic th...

OBJECTIVE To correlate the annoyance of tinnitus assessed by the Tinnitus Handicap Inventory and on a visual analogue scale with the evoked otoacoustic emission test result in tinnitus patients with normal hearing. STUDY DESIGN Case-control study. SETTING Public tertiary hospital. SUBJECTS AND METHODS The sample was initially based on a population of 80 subjects with tinnitus; 20 of them ...

Otoacoustic emissions have historically been measured with an acoustical probe assembly hermetically sealed in the ear canal, imposing in most cases a limited stimulus bandwidth. A physically open recording system should afford the possibility of a greater stimulus bandwidth but the change in acoustical load may affect the magnitude of otoacoustic emissions obtained. Here it is reported that th...

Introduction: Tinnitus is a perception of sound without external source. The exact etiology of tinnitus is not fully understood, although some researchers believe that the condition usually starts in the cochlea. The aim of this study was to determine the potential contribution of outer hair cell dysfunction to chronic tinnitus, by application of Distortion-Product Evoked Otoacoustic Emission (...

OBJECTIVE To assess contralateral suppression of transiently evoked otoacoustic emissions in patients with fibromyalgia syndrome and normal hearing. METHODS Twenty-four female patients with fibromyalgia syndrome and 24 healthy female controls with normal hearing were assessed using pure tone audiometry and transiently evoked otoacoustic emissions. RESULTS All patients with fibromyalgia synd...
