Electronystagmography

I-Electronystagmografi luvavanyo olujonga iintshukumo zamehlo ukubona ukuba zisebenza njani iintlungu ezibini kwingqondo. Ezi luvo zezi:

• I-Vestibular nerve (yesibhozo i-cranial nerve), ebaleka ukusuka kwingqondo iye ezindlebeni
• I-Oculomotor nerve, ebaleka ukusuka kwingqondo iye emehlweni

Iipatches ezibizwa ngokuba zii-electrode zibekwe ngaphezulu, ngezantsi, nakwicala ngalinye lamehlo akho. Zingaba ziipetshi ezinamathelayo okanye ziqhotyoshelwe kwintloko yentloko. Elinye iqhosha lifakwe ebunzini.

Umboneleli wezempilo uya kutshiza amanzi abandayo okanye umoya kwindawo nganye yendlebe ngamaxesha ahlukeneyo. Iipatches zirekhoda intshukumo yamehlo eyenzeka xa indlebe yangaphakathi kunye neethambo ezikufutshane zivuselelwa ngamanzi okanye umoya. Xa amanzi abandayo engena endlebeni, kuya kufuneka ukhawuleze, icala-ne-icala lokuhamba kwamehlo okubizwa ngokuba yinystagmus.

Emva koko, amanzi ashushu okanye umoya ubekwa endlebeni. Amehlo ngoku kufuneka ahambe ngokukhawuleza emanzini ashushu emva koko ahambe kancinci.

Unokucelwa ukuba usebenzise amehlo akho ukulandelela izinto, ezinje ngezibane ezidanyazayo okanye imigca yokuhamba.

Uvavanyo luthatha malunga nemizuzu engama-90.

Uninzi lwexesha, awudingi ukuthatha manyathelo akhethekileyo ngaphambi kolu vavanyo.

• Umboneleli wakho uya kukuxelela ukuba ngaba ufuna ukuyeka ukuthatha nawaphi na amayeza phambi kokuba wenze olu vavanyo.
• SUKUYEKE okanye utshintshe amayeza akho ungakhange uthethe nomboneleli wakho kuqala.

Unokuziva ungonwabanga ngenxa yamanzi abandayo endlebeni. Ngexesha lovavanyo, unokuba:

• Isihlunu okanye ukugabha
• Isiyezi esifutshane (i-vertigo)

Uvavanyo lusetyenziselwa ukumisela ukuba ngaba ibhalansi okanye ukuphazamiseka kwemithambo-luvo kungunobangela wokuba nesiyezi okanye i-vertigo.

Unako ukuluvavanya ukuba unayo:

• Isiyezi okanye i-vertigo
• Ukuphulukana nokuva
• Umonakalo onokubakho kwindlebe yangaphakathi evela kumayeza athile

Ukuhamba kwamehlo okuthile kufuneka kwenzeke emva kokuba amanzi ashushu okanye abandayo okanye umoya ubekwe ezindlebeni zakho.

Qaphela: Uluhlu lwamaxabiso aqhelekileyo luyahluka kancinci phakathi kweelebhu ezahlukeneyo. Thetha nomboneleli wakho malunga nentsingiselo yeziphumo zakho zovavanyo.

Iziphumo ezingaqhelekanga zinokuba luphawu lomonakalo kwimithambo-luvo yendlebe yangaphakathi okanye ezinye iinxalenye zobuchopho ezilawula ukuhamba kwamehlo.

Nasiphi na isifo okanye ukwenzakala okulimaza i-acoustic nerve kunokubangela i-vertigo. Oku kunokubandakanya:

• Ukuphazamiseka kwemithambo yegazi ngokuphuma kwegazi (ukopha), amahlwili, okanye isifo sokuqina kwegazi kwindlebe
• I-cholesteatoma kunye nezinye izicubu zeendlebe
• Iingxaki zokuzalwa
• Ukwenzakala
• Amayeza ayityhefu kwimithambo-luvo yendlebe, kubandakanya aminoglycoside antibiotics, amanye amayeza antimalarial, loop diuretics, kunye ne-salicylates
• Isifo sokugubhuka
• Ukuphazamiseka kwentshukumo njengokuqhubeka kwesifo se-supranuclear palsy
• URubella
• Ezinye iityhefu

Iimeko ezongezelelweyo apho uvavanyo lunokwenziwa khona:

• I-acoustic neuroma
• I-vertigo yesimo seBenign
• ILabyrinthitis
• Isifo seMeniere

Rhoqo, uxinzelelo lwamanzi oluninzi ngaphakathi kwendlebe kunokwenzakalisa igubu lendlebe yakho ukuba kukho umonakalo owenzeke ngaphambili. Inxalenye yamanzi yolu vavanyo akufuneki yenziwe ukuba i-eardrum yakho iye yahlanjwa kutshanje.

I-Electronystagmography iluncedo kakhulu kuba inokurekhoda intshukumo ngasemva kweenkophe ezivaliweyo okanye ngentloko kwiindawo ezininzi.
