I-Electronystagmography

I-Electronystagmography isivivinyo esibheka ukunyakaza kwamehlo ukubona ukuthi izinzwa ezimbili ebuchosheni zisebenza kahle kangakanani. Lezi zinzwa yilezi:

• I-Vestibular nerve (i-eighth cranial nerve), egijima isuka ebuchosheni iye ezindlebeni
• I-Oculomotor nerve, esuka ebuchosheni iye emehlweni

Amachashaza abizwa ngama-electrode abekwe ngaphezulu, ngezansi, nakuhlangothi ngalunye lwamehlo akho. Zingaba iziqinti ezinamathelayo noma zixhunywe ebhandeni lekhanda. Esinye isigaxa sinamathiselwe esiphongweni.

Umhlinzeki wezempilo uzofafaza amanzi abandayo noma umoya emseleni ngamunye wezindlebe ngezikhathi ezihlukene. Amachashazi aqopha ukunyakaza kwamehlo okwenzeka lapho indlebe yangaphakathi nezinzwa eziseduze zikhuthazwa ngamanzi noma emoyeni. Lapho amanzi abandayo engena endlebeni, kufanele ube nokunyakaza kwamehlo okusheshayo, ohlangothini nohlangothi okubizwa nge-nystagmus.

Okulandelayo, kufakwa amanzi afudumele noma umoya endlebeni. Amehlo manje kufanele ahambele ngokushesha emanzini afudumele bese ehamba kancane.

Ungacelwa futhi ukuthi usebenzise amehlo akho ukulandelela izinto, njengezibani ezikhanyayo noma olayini abahambayo.

Ukuhlolwa kuthatha imizuzu engama-90.

Isikhathi esiningi, awudingi ukuthatha izinyathelo ezikhethekile ngaphambi kwalolu vivinyo.

• Umhlinzeki wakho uzokutshela uma udinga ukuyeka ukuthatha noma yimiphi imithi ngaphambi kokwenza lokhu kuhlolwa.
• UNGAYIMISI noma ushintshe imithi yakho ngaphandle kokukhuluma nomhlinzeki wakho kuqala.

Ungazizwa ungakhululekile ngenxa yamanzi abandayo endlebeni. Ngesikhathi sokuhlolwa, ungahle ube:

• Isicanucanu noma ukuhlanza
• Isiyezi esifushane (i-vertigo)

Ukuhlolwa kusetshenziselwa ukuthola ukuthi ngabe ibhalansi noma ukuphazamiseka kwemizwa kuyimbangela yesiyezi noma i-vertigo.

Ungaba nalolu vivinyo uma une:

• Isiyezi noma i-vertigo
• Ukulahlekelwa ukuzwa
• Ukulimala okungenzeka kwendlebe yangaphakathi kusuka emithini ethile

Ukunyakaza okuthile kwamehlo kufanele kwenzeke ngemuva kokufakwa kwamanzi afudumele noma abandayo noma umoya ezindlebeni zakho.

Qaphela: Amabanga wamanani ajwayelekile angahluka kancane kumalabhorethri ahlukile. Khuluma nomhlinzeki wakho mayelana nencazelo yemiphumela yakho ethile yokuhlolwa.

Imiphumela engajwayelekile ingaba wuphawu lokulimaza inzwa yendlebe yangaphakathi noma ezinye izingxenye zobuchopho ezilawula ukunyakaza kwamehlo.

Noma yisiphi isifo noma ukulimala okulimaza i-acoustic nerve kungadala i-vertigo. Lokhu kungafaka:

• Ukuphazamiseka kwemikhumbi yegazi ngokuphuma kwegazi (ukopha), amahlule, noma i-atherosclerosis yegazi lendlebe
• I-cholesteatoma nezinye izicubu zezindlebe
• Izinkinga zokuzalwa
• Ukulimala
• Imithi enobuthi emithanjeni yezindlebe, efaka ama-aminoglycoside antibiotic, eminye imishanguzo yokulwa nomalaleveva, i-loop diuretics nama-salicylates
• I-Multiple sclerosis
• Izinkinga zokuhamba ezinjengokukhubazeka okuqhubekayo kwe-supranuclear
• URubella
• Abanye ubuthi

Izimo ezingeziwe lapho ukuhlolwa kungenziwa khona:

• I-acoustic neuroma
• I-vertigo yesimo se-Benign
• I-Labyrinthitis
• Isifo seMeniere

Imvamisa, umfutho wamanzi omningi ngaphakathi kwendlebe ungalimaza isigubhu sakho sendlebe uma kube nomonakalo wangaphambilini. Ingxenye yamanzi yalolu vivinyo akufanele yenziwe uma i-eardrum yakho igcotshwe muva nje.

I-Electronystagmography iyasiza kakhulu ngoba ingarekhoda ukunyakaza ngemuva kwamajwabu amehlo avaliwe noma ngekhanda ezindaweni eziningi.
