I-OAE imele ukukhishwa kwe-otoacoustic, igama lemisindo eyenziwa yi- cochlea . Lezi zomsindo zingasetshenziswa ukuhlola umsebenzi we-cochlea (ikakhulukazi isisindo somsebenzi wesisindo) nezinye izingxenye zendlebe, kuhlanganise ne-nerve auditory.
Ukusetshenziswa
Ukukhishwa kwama-otoacoustic Ukuvivinywa kokuzwa kuvame ukwenziwa ezinganeni ezisanda kuzalwa ukuze zithole ukuzwa. Ukuhlolwa kungalinganisa ukuzwela kokuzwa kanye nokuhlolwa kokulahlekelwa kokulalela kokusebenza.
Ukulahleka kokuzwa okusebenzayo ngezinye izikhathi kubhekwa njengokulahlekelwa kwezindlebe okungezona eziphilayo kanye nesimo lapho unayo izimpawu noma ukuziphatha kokulahlekelwa kwezindlebe kodwa akukho lutho olungalungile ngokuzwa kwakho.
Imithombo ethile ingase ibhekisele kulokhu njengokulahlekelwa kwezindlebe ezenzelwe kodwa lokhu kungenzeka ukuthi akunembile ngokuphelele ngoba lokhu kusho ukuthi umuntu "uyayifaka" futhi lolu hlobo lokulahlekelwa kwezindlebe lunemvelaphi eminingi engekho ngaso sonke isikhathi ngaphakathi kokulawulwa ngabanye.
Ukukhishwa kwe-Otoacoustic Ukuhlolwa kokuzwa kuvame ukusetshenziswa ngokuhlanganyela nohlolo lwe- ABR (Auditory Brainstem Response) noma ezinye izivivinyo zokulalela.
Ukuhlolwa Kwenziwe kanjani
Ukukhishwa kwama-otoacoustic Ukuzwa ukuhlolwa akuyona ebuhlungu futhi izingane eziningi zilele ngqo. Izindlala ezincane zifakwa endlebeni. Omunye uhambisa umsindo nomunye imakrofoni. Uma i-cochlea isebenza ngokufanele kufanele iphendule ngokuphendula umsindo. Kunezinhlobo ezine zemisindo i-cochlea eveza:
- Ukukhishwa kwamagciwane okungajwayelekile - i-cochlea ikhiqiza lezi zomsindo ngokuzenzekelayo (hhayi ngokuphendula komunye umsindo). Lokhu kwenzeka kuphela kuma-40-50 amaphesenti abantu abanokuzwa okuvamile.
- Ukukhishwa kwe-otoacoustic esheshayo - okukhiqizwa ekuphenduleni omunye umsindo wesikhashana (isikhathi esincane). Ngokuvamile ukuchofoza noma ukuphuma kwetoni. Lezi zivame ukusetshenziswa ukuhlola ukuzwa ezinganeni.
- Ukukhishwa kwemikhiqizo ye-otoacoustic eyenziwa ngokuphazamiseka - okukhiqizwa ekuphenduleni amathoni amabili ngesikhathi esisodwa ehlukahlukene. Lezi ziwusizo ikakhulukazi ekutholeni umonakalo ku-cochlea ekuqaleni (ngokwesibonelo umonakalo ku-cochlea kusuka ekutheni i-ototoxicity noma umonakalo owenziwe ngomsindo).
- Ukukhishwa kwe-otoacoustic evamile - okukhiqizwa ngokuphendula ithoni eqhubekayo. Lezi azijwayele ukuthi zisetshenziswe esimweni semitholampilo.
Ezinye izimo zingabangela ukungabi khona kwe-OAE. Lokhu kufaka phakathi: ama-cysts, i-otitis yangaphandle (indlebe yokudoba ngesibonelo), isifo se-stenosis, noma ingcindezi engavamile engaphakathi, indlebe , i-otosclerosis, i- cholesteatoma .
Ukunemba Kwemiphumela
Ukuhlolwa kwe-OAE akunakukwazi ukuhlolisisa ukulahleka kokuzwa noma ukuzwa. Uma uhluleka ukuhlolwa kwe-OAE uzodinga ukuhlolwa okungeziwe kokuzwa ukuze ubone ukuthi kukhona ukulahlekelwa kokulalela noma cha.
Ngezinye izikhathi ukuhlolwa kwe-OAE akulungile ngoba usana luyinkinga ngesikhathi sokuvivinywa kanti ngezinye izikhathi abantwana banamanzi ezindlebeni zabo noma ezinye izimo ezingabangela ukuba bahluleke ukuhlolwa ngisho noma bengenakho ukulahlekelwa okungahlali njalo. Ezinye izinto ezingabangela ukuhlolwa kwe-OAE ukwehluleka noma ukungalungi kuhlanganisa:
- Isisindo esibi emjikelezweni wezindlebe
- Ukuvalwa kwe-ear, ikakhulukazi uma kuvimbela ukuthola uphawu oluhle nxazonke ze-probe yezindlebe
- Izinto ezingezansi noma izinto zangaphandle emgodini wezindlebe
- Isiguli esingasebenzisani
