Apa videonystagmography (VNG)?

Videonystagmography (VNG) minangka tes sing ngukur jinis gerakan mripat sing ora sengaja diarani nystagmus. Gerakan kasebut bisa alon utawa cepet, tetep utawa sregep. Nystagmus nyebabake mripat sampeyan pindhah saka sisih menyang sisih utawa munggah lan mudhun, utawa kalorone. Mengkono nalika otak entuk pesen sing mbantah saka mripat lan sistem saldo ing kuping njero. Pesen sing mbantah iki bisa nyebabake pusing.

Sampeyan bisa nyedhaki nystagmus nalika mindhah kanthi cara tartamtu utawa ndeleng sawetara jinis pola. Nanging yen sampeyan entuk nalika ora mindhah utawa yen suwene suwe, bisa uga duwe gangguan sistem vestibular.

Sistem vestibular sampeyan kalebu organ, saraf, lan struktur sing ana ing kuping njero. Iki minangka pusat keseimbangan utama awak. Sistem vestibular bisa digunakake bebarengan karo mripat, sentuhan, lan otak. Otak sampeyan komunikasi karo macem-macem sistem ing awak kanggo ngontrol saldo sampeyan.

Jeneng liya: VNG

Digunakake kanggo apa?

VNG digunakake kanggo ngerteni manawa sampeyan duwe kelainan sistem vestibular (struktur keseimbangan ing kuping njero) utawa ing bagean otak sing ngontrol saldo.

Napa aku butuh VNG?

Sampeyan bisa uga butuh VNG yen sampeyan ngalami gejala kelainan vestibular. Gejala utama yaiku pusing, istilah umum kanggo gejala ketidakseimbangan sing beda. Iki kalebu vertigo, rumangsa yen sampeyan utawa lingkungan muter, staggering nalika mlaku-mlaku, lan kulit ringan, rasane kaya sampeyan bakal pingsan.

Gejala kelainan vestibular liyane kalebu:

• Nystagmus (gerakan mripat kanthi ora sengaja sing ana ing sisih utawa munggah lan mudhun)
• Nrungu ing kuping (tinnitus)
• Rasane kebak utawa meksa ing kuping
• Bingung

Apa sing kedadeyan nalika VNG?

VNG bisa ditindakake dening panyedhiya layanan kesehatan utama utawa salah sawijining jinis spesialis ing ngisor iki:

• Audiologis, panyedhiya perawatan kesehatan sing khusus kanggo diagnosa, ngobati, lan ngatur gangguan pendengaran
• Ahli otolaryngologist (ENT), dhokter sing spesialisasine kanggo ngrawat penyakit lan kahanan kuping, irung, lan tenggorokan
• Ahli saraf, dhokter sing khusus kanggo diagnosa lan ngrawat kelainan otak lan sistem saraf

Sajrone tes VNG, sampeyan bakal lungguh ing ruangan peteng lan nganggo kacamata khusus. Kacamata duwe kamera sing nyathet obahe mripat. Ana telung bagean utama VNG:

• Tes okuler. Sajrone bagean VNG iki, sampeyan bakal bisa ndeleng lan ngetutake titik-titik sing obah lan ora obah ing bar cahya.
• Tes Posisi Sajrone bagean iki, panyedhiya sampeyan bakal mindhah sirah lan awak kanthi posisi sing beda. Penyedia sampeyan bakal mriksa manawa gerakan iki nyebabake nystagmus.
• Pengujian kalori. Sajrone bagean iki, banyu utawa hawa sing anget lan adhem bakal dilebokake ing saben kuping. Nalika banyu utawa hawa adhem mlebu ing kuping njero, mula kudu nystagmus. Mripat banjur pindhah saka banyu adhem ing kuping lan alon-alon bali. Nalika banyu anget utawa udhara dilebokake ing kuping, mripat kudu alon-alon pindhah menyang kuping lan alon-alon bali. Yen mripat ora nanggapi kanthi cara kasebut, bisa uga ana gangguan saraf ing kuping njero. Panyedhiya sampeyan uga bakal mriksa manawa kuping siji nanggapi beda karo liyane. Yen kuping siji rusak, reaksi bakal luwih lemah tinimbang liyane, utawa bisa uga ora ana respon apa-apa.

Apa aku kudu nindakake apa-apa kanggo nyiapake VNG?

Sampeyan bisa uga kudu nggawe pangowahan ing panganan utawa ngindhari obat-obatan tartamtu sajrone sedina utawa rong dina sadurunge tes. Panyedhiya layanan kesehatan bakal menehi ngerti manawa ana instruksi khusus sing kudu ditindakake.

Apa ana risiko VNG?

Tes kasebut bisa nggawe sampeyan ngelu sawetara menit. Sampeyan bisa uga pengin nggawe wong sing nggawa sampeyan ing omah, yen pusing bisa suwe.

Apa tegese asile?

Yen asile ora normal, bisa uga duwe gangguan ing kuping njero. Iki kalebu:

• Penyakit Meniere, kelainan sing nyebabake pusing, gangguan pendengaran, lan tinnitus (nuli ing kuping). Biasane mung kena kuping siji. Sanajan ora ana obat kanggo penyakit Meniere, kelainan kasebut bisa uga diatasi kanthi obat lan / utawa owah-owahan ing panganan.
• Labyrinthitis, kelainan sing nyebabake vertigo lan ora seimbang. Iki disebabake nalika bagean kuping utama kena infeksi utawa bengkak. Kelainan kasebut kadang-kadang ilang dhewe, nanging sampeyan bisa uga diwenehi resep antibiotik yen didiagnosis kena infeksi.

Asil sing ora normal bisa uga tegese sampeyan duwe kahanan sing mengaruhi bagean-bagean otak sing mbantu ngontrol saldo.

Yen sampeyan duwe pitakon babagan asil, guneman karo panyedhiya layanan kesehatan.

Apa ana bab liya sing kudu dakkerteni babagan VNG?

Tes liyane sing diarani electronystagmography (ENG) ngukur jinis gerakan mata sing padha karo VNG. Uga nggunakake tes okuler, posisional, lan kalori. Nanging tinimbang nggunakake kamera kanggo ngrekam gerakan mripat, ENG ngukur gerakan mripat kanthi elektroda sing dipasang ing kulit ing sekitar mripat.

Nalika tes ENG isih digunakake, tes VNG saiki luwih umum. Beda karo ENG, VNG bisa ngukur lan ngrekam gerakan mripat kanthi nyata. VNG uga bisa nyedhiyakake gambar gerakan mata sing luwih jelas.
