Videonystagmography (VNG) yog dab tsi?

Videonystagmography (VNG) yog ib qho kev ntsuas uas ntsuas ib hom kev txav qhov muag hu ua nystagmus. Cov kev txav no tuaj yeem ua qeeb lossis nrawm, khov kho lossis nrawm. Nystagmus ua rau koj lub qhov muag txav ntawm sab rau sab lossis nce thiab nqis, lossis ob qho tib si. Nws tshwm sim thaum lub hlwb tau txais cov lus tsis sib haum xeeb los ntawm koj lub qhov muag thiab qhov sib npaug ntawm pob ntseg sab hauv. Cov lus tsis sib haum no tuaj yeem ua rau kiv taub hau.

Koj tuaj yeem luv luv nystagmus thaum koj txav koj lub taub hau ib txoj kev lossis saib qee hom qauv. Tab sis yog tias koj tau txais thaum koj tsis tshem koj lub taub hau lossis yog tias nws kav ntev, nws yuav txhais tau tias koj muaj qhov tsis txaus siab ntawm cov kab ke vestibular.

Koj lub tsho khuam kom sib haum suav nrog cov khoom nruab nrog, cov hlab ntsha, thiab cov qauv hauv koj pob ntseg sab hauv. Nws yog koj lub cev qhov chaw tseem ceeb ntawm kev tshuav nyiaj li cas. Lub tsho khuam ua haujlwm ua haujlwm ua ke nrog koj ob lub qhov muag, nkag siab, thiab lub hlwb. Koj lub paj hlwb sib txuas lus nrog cov sib txawv hauv koj lub cev los tswj koj qhov sib npaug.

Lwm lub npe: VNG

Nws siv rau dab tsi?

VNG raug siv txhawm rau txhawm rau paub tias koj muaj kev tsis sib haum xeeb ntawm cov txheej txheem vestibular (cov qauv sib npaug hauv koj lub pob ntseg sab hauv) lossis hauv feem ntawm lub hlwb uas tswj kev tshuav.

Vim Li Cas Kuv Thiaj Yuav Tsum VNG?

Koj yuav tsum muaj VNG yog tias koj muaj cov tsos mob ntawm qhov tsis haum vestibular. Cov tsos mob tseem ceeb yog kiv taub hau, ib nqe lus dav dav rau cov tsos mob sib txawv ntawm tsis txaus. Cov no suav nrog vertigo, lub siab uas koj lossis koj ib puag ncig tig mus, tig mus thaum taug kev, thiab lub teeb ci ntsa iab, qhov kev xav zoo li koj yuav tsaus muag.

Lwm cov tsos mob ntawm daim ntaub qhwv ntsej muag suav nrog:

• Nystagmus (tsis nyiam qhov muag txav uas mus ib sab los yog nce thiab nqis)
• Lub pob ntseg hauv pob ntseg (tinnitus)
• Zoo nkaus li muaj qhov puv lossis siab hauv lub pob ntseg
• Tsis meej pem

Yuav muaj dab tsi tshwm sim thaum VNG?

VNG yuav ua tau los ntawm tus thawj saib xyuas kev noj qab haus huv lossis ib ntawm cov neeg tshwj xeeb hauv qab no:

• Tus kws ntsuas mob, ib tus kws saib xyuas kev noj qab haus huv uas tshwj xeeb hauv kev kuaj mob, kho mob, thiab tswj kev hnov ​​lus
• Tus kws kho mob otolaryngologist (ENT), kws kho mob tshwj xeeb hauv kev kho cov kab mob thiab cov mob ntawm pob ntseg, qhov ntswg, thiab caj pas
• Tus kws kho paj hlwb (neurologist), kws kho mob tshwj xeeb hauv kev txheeb xyuas thiab kho mob tsis zoo ntawm lub hlwb thiab lub paj hlwb

Thaum lub sij hawm VNG xeem, koj yuav zaum hauv chav tsaus thiab hnav looj hnab tshwj xeeb. Cov tsom iav tau muaj lub koob yees duab uas sau cov qhov muag txav. Muaj peb ntu tseem ceeb rau VNG:

• Kev soj ntsuam leeg. Lub sijhawm VNG no, koj yuav saib thiab ua raws li txav chaw thiab tsis ntsuas ntawm lub teeb.
• Txoj haujlwm kuaj. Hauv ntu no, koj tus kws kho mob yuav txav koj lub taub hau thiab lub cev sib txawv. Koj tus kws khomob yuav tshawb xyuas yog tias qhov kev txav no ua rau nystagmus.
• Kev ntsuas caloric. Hauv ntu no, cov dej sov thiab dej txias lossis cua yuav muab tso rau hauv txhua lub pob ntseg. Thaum cov dej txias lossis cua nkag mus rau sab hauv pob ntseg, nws yuav tsum ua rau nystagmus. Qhov muag yuav tsum txav mus deb ntawm cov dej txias hauv lub pob ntseg ntawd thiab maj mam tig rov qab. Thaum muab dej sov lossis cua tso rau hauv pob ntseg, lub qhov muag yuav tsum txav maj mam mus rau lub pob ntseg ntawd thiab maj mam rov qab. Yog tias lub qhov muag tsis teb cov lus no, nws yuav txhais tau tias muaj kev puas tsuaj rau cov leeg ntshav ntawm lub pob ntseg sab hauv. Koj tus kws khomob yuav tshawb xyuas seb lub ntsej muag puas hnov ​​txawv ntawm lwm tus. Yog tias ib lub pob ntseg tsis zoo, lub teb yuav tsis muaj zog dua li lwm lub, lossis yuav tsis muaj lus teb txhua.

Kuv puas yuav tau ua dab tsi los npaj rau VNG?

Koj yuav tau hloov pauv koj li kev noj haus lossis zam qee yam tshuaj noj rau ib hnub lossis ob uantej koj yuav mus xeem. Koj tus kws kho mob yuav qhia rau koj paub yog tias nws muaj lus qhia tshwj xeeb ua raws.

Puas muaj kev pheej hmoo rau VNG?

Qhov sim yuav ua rau koj xav tias kiv taub hau rau ob peb feeb. Koj tuaj yeem npaj cov neeg thauj koj mus rau hauv tsev, yog tias cov kiv tob hau nyob ntev dua.

Cov txiaj ntsig li cas?

Yog tias cov txiaj ntsig tsis zoo li qub, nws yuav txhais tau tias koj muaj qhov tsis zoo ntawm lub pob ntseg sab hauv. Cov no suav nrog:

• Meniere's disease, kev tsis txaus siab uas ua rau kiv taub hau, mob pob ntseg, thiab hnov ​​pob ntseg (nrov hauv pob ntseg). Feem ntau nws cuam tshuam tsuas yog ib lub pob ntseg. Txawm hais tias tsis muaj kev kho rau Meniere's disease, qhov kev tsis zoo yuav raug tswj nrog tshuaj thiab / lossis kev hloov pauv ntawm koj cov zaub mov noj.
• Labyrinthitis, kev tsis sib haum xeeb uas ua rau mob vertigo thiab tsis txaus ntseeg. Nws tshwm sim thaum ib feem ntawm sab hauv pob ntseg ua mob lossis o tuaj. Qhov tshwm sim qee zaum ploj mus ntawm nws tus kheej, tab sis koj tuaj yeem siv tshuaj kho mob yog tias koj paub tias muaj kab mob.

Qhov tshwm sim txawv txav kuj tseem txhais tau tias koj muaj ib qho mob uas cuam tshuam rau cov ntu ntawm lub hlwb uas pab tswj hwm koj cov nyiaj tshuav.

Yog koj muaj lus nug txog koj cov txiaj ntsig, nrog koj tus kws kho mob tham.

Puas muaj lwm yam ntxiv uas kuv xav paub txog VNG?

Lwm qhov kev sim hu ua electronystagmography (ENG) ntsuas tib hom txav ntawm qhov muag raws li VNG. Nws kuj siv kev kuaj xyuas ovular, qhov chaw, thiab ntsuas cov caloric. Tab sis es tsis txhob siv lub koob yees duab los sau qhov muag ntawm qhov muag, ib qho ENG ntsuas qhov muag txav nrog electrodes tso rau ntawm daim tawv nqaij ncig lub qhov muag.

Thaum kuaj ENG tseem siv, kev kuaj VNG tam sim no muaj ntau dua. Tsis zoo li ENG, VNG tuaj yeem ntsuas thiab sau qhov muag kom pom tseeb hauv lub sijhawm. VNGs tseem tuaj yeem muab cov duab pom tseeb ntawm qhov muag txav tau.
