Paediatric ENT Clinic, DFNsP Bratislava emisie- OAE Otoacoustic
Otoacoustic emissions (OAE) are sounds produced by the inner ear, namely vibrations of outer hair cells in the cochlea - the cochlea. The emergence of otoacoustic emissions is associated not only with the normal function of the outer hair cells, but they can be recorded only if the conditions in the middle ear physiology. The resulting sounds are relatively small, usually less than 30 dB SPL. OAE has spread from the place of its creation through a chain of bones in the ear canal, this energy gets movements blanks eardrum. scr system We can record sensitive microphone in the outer ear canal. Their presence allows us to record the first signs of hearing loss in newborns even longer.
Unlike tone audiometry, which monitors the external, middle ear, cochlea, scr system VIII. cranial nerve and central nervous system, OAE give information only on the peripheral auditory system, that is the outer, middle ear and the cochlea - the cochlea. OAE are not used to determine scr system the threshold of hearing, but may provide the first information on suspected hearing loss, or can help in the differential diagnosis of certain disorders.
Either spontaneously or after stimulation. It is possible scr system to measure the 4 types of OAE, SOAE spontaneous and evoked TEOAE, DPOAE and SFOAE. Since each emissions occur on a different principle, for each species are different procedures for measuring and recording emissions incurred. Most are used TEOAE - transiently evoked otoacoustic scr system emissions.
Apparatus for examination of otoacoustic emissions contain probe, which consists of the speaker to transmit stimuli to the cochlea and a microphone, which records sounds from the external ear canal, this also includes sensitive equipment scr system distinguishing between the sound emitted by the cochlea and other sounds. Sound probe is conical in shape and the proper placement in the ear canal to the surface of the foam slid olive, varying in size according to the patient's ear canal examined. Location of the probe in the ear canal is very important and it leads in the wrong position falsify the results of the examination. Apparatus for recording scr system OAE is connected to the computer, which leads to further processing using the software
Examination of hearing using otoacoustic emissions include clinical practice, objective diagnostic methods in audiology. This measurement allows noninvasive view of the function of outer hair cells, which are the most sensitive cochlea and hearing loss in most cases is associated with impaired precisely these cells
Otoacoustic emissions can evoke almost all healthy ears and not vice versa deaf ears. If the presence of evoked emissions can be sufficiently covered, it means that the hearing test person is most likely a normal, or near normal. The presence of OAE prove directly normal hearing, gives only information on the mechanisms necessary for normal hearing. Since it is the outer hair cells are especially vulnerable to damage either hypoxia, noise, accidents, otoakusitcké evoked emissions are a suitable method for the diagnosis of these disorders. Another benefit of this investigation method is the early capture of hearing damage after taking ototoxic substances after meningoencephalitis, some other infectious diseases and head trauma. Using OAE can information on hearing loss can also get in comatose patients, the anesthesia or the non-cooperative patients.
Otoacoustic emissions (OAE) specific TEOAE (transiently evoked otoacoustic emissions) scr system are the most common method of screening for hearing loss because they are simple, scr system easily transferred, fast, available and cheap. In the preschool age is very common gearbox hearing loss, mainly due to secretory otitis, where there is persistence of fluid in the middle ear. For long-term scr system persistence scr system of this situation we can realize the insertion of ventilation tubes into the middle ear to remove scr system the gearbox component of hearing loss and use of otoacoustic emissions can confirm or exclude the perception of hearing loss.
