Chimene Mukuyenera Kudziwa Pankhani ya Kutuluka kwa Otoacoustic (OAE) Kumva Mayesero

OAE imaimira mpweya wa otoacoustic, dzina la phokoso lopangidwa ndi cochlea . Zimveka izi zingagwiritsidwe ntchito kuyesa ntchito ya cochlea (makamaka maselo a tsitsi la tsitsi) ndi mbali zina za khutu, kuphatikizapo mitsempha yolondola.

Ntchito

Mphuphu ya Otoacoustic Kawirikawiri kumvetsera kumvetsera kumachitika kwa ana akhanda kuti azindikire kugontha. Chiyesochi chingathenso kulingalira za mphamvu zowakomera kumva ndi kuyesa kwa kutayika kwakumvetsera.

Kuwonongeka kwakumvetsera kumatchulidwanso nthawi zina kumatayika kumvetsedwe komanso kumakhala kuti muli ndi zizindikiro kapena khalidwe lakumva koma palibe cholakwika ndi kumva kwanu.

Zina mwazinthu zingatanthauzire izi ngati kutayika kumvetserani koma mwina siziri zolondola chifukwa izi zikutanthauza kuti wina "akuziwongolera" ndipo kutaya kwakumva kumeneku kumakhala kosavuta nthawi zonse.

Kuphulika kwa Otoacoustic Kumvetsera kumvetsera kumagwiritsidwa ntchito mogwirizanitsa ndi mayeso omvera a ABR (Auditory Brainstem Response) kapena mayesero ena akumvetsera.

Mmene Testhi Imapangidwira

Kutulutsa kwa Otoacoustic Kumva kuyesa sikumvetsa chisoni ndipo ana ambiri amagona pomwepo. Mapulotete aang'ono amaikidwa mu khutu. Mmodzi amapereka phokoso ndipo winayo ndi maikolofoni. Ngati cochlea ikugwira ntchito bwino, iyeneranso kuyankha poyankha. Pali mitundu inayi ya mawonekedwe omwe cochlea imapanga:

1. Kutulutsa mpweya wokhazikika - chokoma chimapangitsa izi kumveka pokhapokha (osati motsatira mawu ena). Izi zimangokhala pafupifupi 40-50 peresenti ya anthu omwe amamva bwino.
2. Mpweya wamtambo wamtundu wautali - wopangidwa motsatizana ndi liwu lina laifupi (nthawi yayitali). Kawirikawiri amajambulira kapena kutuluka. Izi zimagwiritsidwa ntchito poyesa kumva kumvetsera kwa makanda.

1. Zosokoneza zopangira mankhwala odzola - zopangidwa motsatizana ndi zizindikiro ziwiri zomwe zimagwirizana panthawi imodzi. Izi ndi zothandiza makamaka pozindikira kuwonongeka kwa cochlea kumayambiriro (mwachitsanzo, kuwonongeka kwa cochlea kuchokera ku ototoxicity kapena kupwetekedwa koopsa).
2. Kutulutsa - mafupipafupi otoacoustic emissions - opangidwa motsatira mawu opitilira. Izi sizimagwiritsidwa ntchito panthawi yamakono.

Zifukwa zina zingayambitse kupezeka kwa OAE. Izi zimaphatikizapo: cysts, kunja otitis (khutu la kusambira, chitsanzo cha stenosis, kapena kupweteka kwa khutu pakati, khutu, khutu , olesclerosis, cholesteatoma .

Kutsimikizika kwa Zotsatira

OAE kuyezetsa sangathe kuzindikira bwinobwino kumva kumva kapena kugontha. Ngati mukulephera OAE kuyesa mukufunikira kuyesedwa kwakumvetsera kuti muwone ngati pali kumva kapena ayi.

Nthawi zina mayeso a OAE sali olondola chifukwa khanda limakhala lovuta panthawi ya kuyesedwa ndipo nthawizina makanda amakhala ndi makutu m'makutu mwawo kapena zinthu zina zomwe zingawachititse kuti alephere kuyesedwa ngakhale kuti alibe chiwonongeko chosatha. Zifukwa zina zomwe zingayambitse OAE kuyesa kulephera kapena zosayenera zikuphatikizapo:

• Chisindikizo chosavuta kuzungulira kafukufuku wa khutu
• Mphuno yamkati imatsekeka, makamaka ngati imalepheretsa kusindikizidwa bwino kuzungulira khutu la khutu

• Zosokonezeka kapena zinthu zakunja m'ngalande ya khutu
• Wodwala wosagwirizana
