A 12-year-old female patient presented with unilateral sensorineural hearing loss. Distortion-product otoacoustic emission testing failed to reveal any measurable emissions in the affected side. MR imaging did not reveal labyrinthine malformation. Three-dimensional Fourier transformation-constructive interference in steady-state MR images showed a thin cochlear branch. We speculated that mumps ...
Acknowledgement The project was funded by the Medical University of Innsbruck. The purchase of the otoacoustic emission machines was supported by the Company Otometric, Taastup, Denmark and MedEL, Innsbruck, Austria. The local infrastructure was provided by the SMAC II study group. This clinical trial was partially funded by The European and Developing Countries Clinical Trials Partnership (EDC...
OBJECTIVE The purpose of this study was to evaluate, by using distortion product otoacoustic emission test, the action of Ginkgo biloba extract 761, which has a known antioxidant property, as a possible otoprotective against cisplatin induced hearing loss. This prospective and double blinded study was conducted on individuals that were to begin cisplatin treatment in a tertiary university cente...
It has been reported that both click-evoked otoacoustic emissions (CEOAEs) and distortion product otoacoustic emissions (DPOAEs) have higher amplitudes in ears that possess spontaneous otoacoustic emissions (SOAEs). The general aim of the present study was to investigate whether the presence of spontaneous activity in the cochlea affected tone-burst evoked otoacoustic emissions (TBOAEs). As a b...
UNLABELLED Manipulation of auditory stimuli affect the ABR evoked potentials and aid the diagnosis, particularly in auditory neuropathy patients. Some patients with auditory neuropathy lose evoked otoacoustic emissions over time; in these cases, comparing responses to rarefaction and condensation clicks, and decreasing the stimulus rate can show an extended cochlear microphonism or yield an imp...
Mani pulation of auditory stimuli affect the ABR evoked potentials and aid the diagnosis, particularly in auditory neuropathy patients. Some patients with auditory neuropathy lose evoked otoacoustic emissions over time; in these cases, comparing responses to rarefaction and condensation clicks, and decreasing the stimulus rate can show an extended cochlear microphonism or yield an improved elec...
UNLABELLED 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 2...
The paper describes some design aspect of an otoacoustic emissions (OAE) instrument for hearing assessment by using a personal computer and its affiliated sound card. The instrument functionality are achieved by means of virtual instrumentation programmed with LabVIEW utilities. Such OAE instrument is of high quality but relatively inexpensive , and has the potential for laboratory research and...
