Kuyini i-videonystagmography (VNG)?

IVideonystagmography (VNG) isivivinyo esilinganisa uhlobo lokunyakaza kwamehlo okungazibandakanyi okubizwa nge-nystagmus. Le minyakazo ingahamba kancane noma isheshe, izinze noma ijikijele. I-Nystagmus ibangela ukuthi amehlo akho ahambe ngapha nangapha noma phezulu nangaphansi, noma zombili. Kwenzeka lapho ubuchopho buthola imiyalezo ephikisanayo evela emehlweni akho nohlelo lokulinganisela endlebeni yangaphakathi. Le milayezo ephikisanayo ingadala isiyezi.

Ungathola i-nystagmus kafushane lapho uhambisa ikhanda lakho ngendlela ethile noma ubheka ezinye izinhlobo zamaphethini. Kodwa uma uyithola lapho ungahambisi ikhanda lakho noma uma ihlala isikhathi eside, kungasho ukuthi unenkinga yohlelo lwe-vestibular.

Uhlelo lwakho lwe-vestibular lubandakanya izitho, izinzwa, nezakhiwo ezisendlebeni yakho yangaphakathi. Kuyisikhungo esiyinhloko sokulinganisela komzimba wakho. Uhlelo lwe-vestibular lusebenza ngamehlo akho, umuzwa wokuthinta, nobuchopho. Ubuchopho bakho buxhumana nezinhlelo ezahlukahlukene emzimbeni wakho ukulawula ibhalansi yakho.

Amanye amagama: VNG

Kusetshenziselwa ini?

I-VNG isetshenziselwa ukuthola ukuthi unenkinga yini yohlelo lwe-vestibular (izakhiwo zebhalansi endlebeni yakho yangaphakathi) noma engxenyeni yobuchopho elawula ibhalansi.

Kungani ngidinga i-VNG?

Ungadinga i-VNG uma unezimpawu zesifo se-vestibular. Uphawu oluyinhloko isiyezi, igama elijwayelekile lezimpawu ezahlukahlukene zokungalingani. Lokhu kufaka phakathi i-vertigo, umuzwa wokuthi wena noma okuzungezile ujikeleza, uyadiyazela ngenkathi uhamba, nekhanda elincane, umuzwa wokuthi uzophela amandla.

Ezinye izimpawu zesifo se-vestibular zifaka:

• I-Nystagmus (ukunyakaza kwamehlo okungazibandakanyi okuya ngapha nangapha noma phezulu naphansi)
• Ukukhala ezindlebeni (tinnitus)
• Ukuzwa ukugcwala noma ingcindezi endlebeni
• Ukudideka

Kwenzekani ngesikhathi se-VNG?

I-VNG ingenziwa ngumhlinzeki wezempilo oyinhloko noma olunye lwezinhlobo ezilandelayo zochwepheshe:

• Isazi sokuzwa, umhlinzeki wezokunakekelwa kwezempilo ogxile ekuxilongeni, ekwelapheni nasekuphatheni ukulahleka kokuzwa
• I-otolaryngologist (ENT), udokotela onguchwepheshe ekwelapheni izifo nemibandela yezindlebe, ikhala, nomphimbo
• Isazi sezinzwa, udokotela ogxile ekuhloleni nasekwelapheni ukuphazamiseka kobuchopho nohlelo lwezinzwa

Ngesikhathi sokuhlolwa kwe-VNG, uzohlala egumbini elimnyama futhi ugqoke izibuko ezikhethekile. Izibuko zinekhamera erekhoda ukunyakaza kwamehlo. Kunezingxenye ezintathu eziyinhloko ze-VNG:

• Ukuhlolwa kwe-Ocular. Ngalesi sigaba se-VNG, uzobuka futhi ulandele amachashazi ahambayo nongahambi kubha yokukhanyisa.
• Ukuhlolwa kwesimo. Ngalesi sigaba, umhlinzeki wakho uzohambisa ikhanda nomzimba wakho ezindaweni ezahlukahlukene. Umhlinzeki wakho uzohlola ukuthi le nhlangano ibangela i-nystagmus.
• Ukuhlolwa kwekhalori. Ngalesi sigaba, amanzi afudumele futhi apholile noma umoya kuzobekwa endlebeni ngayinye. Lapho amanzi abandayo noma umoya ungena endlebeni yangaphakathi, kufanele kubangele i-nystagmus. Amehlo kufanele ukuthi asuke emanzini abandayo akuleyo ndlebe abuye kancane. Lapho kufakwa amanzi afudumele noma umoya endlebeni, amehlo kufanele ahambe kancane aye kuleyo ndlebe abuye kancane. Uma amehlo engaphenduli ngalezi zindlela, kungasho ukuthi kukhona ukulimala kwezinzwa zendlebe yangaphakathi. Umhlinzeki wakho uzohlola nokuthi indlebe eyodwa iphendula ngokuhlukile yini kolunye. Uma indlebe eyodwa yonakele, impendulo izoba buthakathaka kunenye, noma kungabikhona mpendulo nhlobo.

Ngabe kuzodingeka ngenze noma yini ukulungiselela i-VNG?

Ungadinga ukwenza izinguquko ekudleni kwakho noma uvikele imithi ethile usuku noma ezimbili ngaphambi kokuhlolwa kwakho. Umhlinzeki wakho wezokunakekelwa kwempilo uzokwazisa uma ngabe kukhona imiyalelo ekhethekile ongayilandela.

Ingabe zikhona izingozi ku-VNG?

Ukuhlolwa kungakwenza uzizwe unesiyezi imizuzu embalwa. Ungahle ufune ukwenza amalungiselelo okuthi omunye umuntu akuhambise ngemoto aye ekhaya, uma kwenzeka isiyezi sihlala isikhathi eside.

Isho ukuthini imiphumela?

Uma imiphumela ibingejwayelekile, kungasho ukuthi unenkinga yendlebe yangaphakathi. Lokhu kufaka phakathi:

• Isifo sikaMeniere, ukuphazamiseka okubangela isiyezi, izikhathi zokuzwa, kanye ne-tinnitus (ukukhala ezindlebeni). Imvamisa kuthinta indlebe eyodwa kuphela. Yize lungekho ikhambi lesifo sikaMeniere, lesi sifo singaphathwa ngomuthi kanye / noma ushintsho ekudleni kwakho.
• I-Labyrinthitis, ukuphazamiseka okubangela i-vertigo nokungalingani. Kubangelwa lapho ingxenye yendlebe yangaphakathi itheleleka noma ivuvukala. Lesi sifo kwesinye isikhathi siyazihambela, kepha ungahle unikezwe ama-antibiotic uma kutholakala ukuthi unesifo.

Umphumela ongajwayelekile ungasho nokuthi unesimo esithinta izingxenye zobuchopho ezisiza ukulawula ibhalansi yakho.

Uma unemibuzo ngemiphumela yakho, khuluma nomhlinzeki wakho wezokunakekelwa kwempilo.

Ngabe kukhona okunye engidinga ukukwazi nge-VNG?

Olunye uvivinyo olubizwa nge-electronystagmography (ENG) lilinganisa uhlobo olufanayo lokunyakaza kwamehlo njenge-VNG. Ibuye isebenzise ukuhlolwa kwe-ocular, positional, ne-caloric. Kepha esikhundleni sokusebenzisa ikhamera ukuqopha ukunyakaza kwamehlo, i-ENG ilinganisa ukunyakaza kwamehlo ngama-electrode abekwe esikhumbeni esiseduze kwamehlo.

Ngenkathi ukuhlolwa kwe-ENG kusasetshenziswa, ukuhlolwa kwe-VNG manje sekuvame kakhulu. Ngokungafani ne-ENG, i-VNG ingalinganisa futhi iqophe ukunyakaza kwamehlo ngesikhathi sangempela. Ama-VNG nawo anganikeza ngezithombe ezicacile zokuhamba kwamehlo.
