Vestibular evoked myogenic potentials in patients with acoustic neuromas.
BACKGROUND To diagnose acoustic neuromas (ANs), the auditory brainstem response test and the caloric test have been used in addition to magnetic resonance imaging. The auditory brainstem response and the caloric tests mainly reflect functions of the auditory pathway, ie, the cochlear nerve and the superior vestibular nerve, respectively. Because the vestibular evoked myogenic potential (VEMP) h...
متن کاملContralateral Acoustic Effect of Transient Evoked Otoacoustic Emissions in Neonates.
Contralateral acoustic stimulation (CAS) has the effect of reducing the amplitude of transient evoked otoacoustic emissions (TEOAE) of the opposite cochlea. This phenomenon is considered to be mediated via the efferent pathway, from the superior olivary complex through the medial olivocochlear system to the contralateral cochlea. The assessment of this suppressive effect provides an objective a...
متن کاملThe relationship between ultra-high frequency thresholds and transient evoked otoacoustic emissions in adults with tinnitus
Background: The possible role of cochlear function in tinnitus generation is still a matter of debate. To assess the role of outer hair cell dysfunction in tinnitus and its possible relationship with ultra-high frequency (UHF) hearing sensitivity, transient evoked otoacoustic emissions (TEOAE) and UHF hearing thresholds were investigated in normal hearing individuals with and withou...
متن کاملThe effects of aging on evoked otoacoustic emissions and efferent suppression of transient evoked otoacoustic emissions.
OBJECTIVE There is still controversy regarding the effects of aging on evoked otoacoustic emissions (EOAEs), as well as on the efferent system measured by contralateral acoustic stimulation of EOAEs. The purpose of this study was to investigate the deterioration in EOAEs and efferent suppression (ES) in a representative sample statistically controlling for the differences in hearing thresholds....
متن کاملNoise-evoked otoacoustic emissions in humans.
Click-evoked otoacoustic emissions (CEOAEs) and acoustical responses evoked by bandlimited Gaussian noise (noise-evoked otoacoustic emissions; NEOAEs) were measured in three normal-hearing subjects. For the NEOAEs the first- and second-order Wiener kernel and polynomial correlation functions up to the sixth order were calculated by cross correlating the noise stimulus and the emission response....
