I-acoustic neuroma

I-acoustic neuroma sisisu esikhula kancinci kwisantya esidibanisa indlebe nengqondo. Le nerve ibizwa ngokuba yi-vestibular cochlear nerve. Kusemva kwendlebe, kanye phantsi kobuchopho.

I-neuroma ye-acoustic inobungozi. Oku kuthetha ukuba ayisasazeki kwamanye amalungu omzimba. Nangona kunjalo, inokonakalisa imithambo-luvo ebalulekileyo njengoko ikhula.

I-Acoustic neuromas inxulunyaniswe nohlobo lwe-genetic neurofibromatosis type 2 (NF2).

I-Acoustic neuromas ayiqhelekanga.

Iimpawu ziyahluka, ngokuxhomekeke kubungakanani kunye nendawo yethumba. Ngenxa yokuba ithumba likhula kancinci, iimpawu zihlala ziqala emva kweminyaka engama-30.

Iimpawu eziqhelekileyo zibandakanya:

• Imvakalelo engaqhelekanga yokuhamba (i-vertigo)
• Ukuva ilahleko kwindlebe echaphazelekayo eyenza ukuba kube nzima ukuva incoko
• Ukukhala (tinnitus) kwindlebe echaphazelekayo

Iimpawu eziqhelekileyo ziquka:

• Kunzima ukuqonda intetho
• Ukuba nesiyezi
• Intloko ebuhlungu
• Ukuphulukana nokulingana
• Ukuba ndindisholo ebusweni okanye endlebeni
• Ubuhlungu ebusweni okanye indlebe enye
• Ubuthathaka bobuso okanye i-asymmetry yobuso

Umboneleli wezempilo unokurhanela i-acoustic neuroma esekwe kwimbali yakho yezonyango, kuvavanyo lwenkqubo yakho yeemvakalelo, okanye iimvavanyo.

Rhoqo, uvavanyo lomzimba luqhelekile xa kufunyenwe ithumba. Ngamanye amaxesha, le miqondiso ilandelayo inokubakho:

• Ukuncipha kwemvakalelo kwelinye icala lobuso
• Ukujula kwelinye icala lobuso
• Ukuhamba okungazinzanga

Olona vavanyo luluncedo kakhulu lokuchonga i-acoustic neuroma yi-MRI yengqondo. Ezinye iimvavanyo zokufumanisa i-tumor kwaye uyixelele ngaphandle kwezinye izizathu zesisu okanye i-vertigo zibandakanya:

• Uvavanyo lokuva
• Uvavanyo lokulingana kunye nokulingana (i-electronystagmography)
• Uvavanyo lokuva kunye nokusebenza kwengqondo (impendulo yovandlakanyo lwengqondo)

Unyango luxhomekeke kubungakanani kunye nendawo yethumba, iminyaka yakho kunye nempilo yakho iyonke. Wena kunye nomboneleli wakho kufuneka uthathe isigqibo sokuba ulibukele na ithumba ngaphandle konyango, sebenzisa imitha ukusinqanda ukuba singakhuli, okanye uzame ukulisusa.

Uninzi lwee-acoustic neuromas zincinci kwaye zikhula kancinci. Amathumba amancinci aneempawu ezimbalwa okanye engenazo anokujongwa utshintsho, ngakumbi kubantu abadala. Ukuskena rhoqo kweMRI kuya kwenziwa.

Ukuba ayinyangwa, ezinye ii-acoustic neuromas zinako:

• Ukonakaliswa kwemithambo-luvo ebandakanyekileyo kwindlebe kunye nokulinganisela
• Beka uxinzelelo kwizicubu zobuchopho ezikufutshane
• Yonakalisa imithambo-luvo inoxanduva lokuhamba kunye neemvakalelo ebusweni
• Khokelela ekwakhiweni kolwelo (i-hydrocephalus) kwingqondo (enamathumba amakhulu kakhulu)

Ukususa i-acoustic neuroma kuqhele ukwenziwa:

• Amathumba amakhulu
• Izidumba ezibangela iimpawu
• Izidumba ezikhula ngokukhawuleza
• Izidumba ezixineneyo kwingqondo

Utyando okanye uhlobo lonyango lwemitha lwenziwa ukususa ithumba kunye nokuthintela omnye umonakalo we-nerve. Kuxhomekeka kuhlobo lotyando olwenziwe, ukuva ngamanye amaxesha kunokugcinwa.

• Inkqubo yotyando yokususa i-acoustic neuroma ibizwa ngokuba yi-microsurgery. Kusetyenziswa imicroscope ekhethekileyo kunye nezixhobo ezincinci ezichanekileyo. Obu buchule bunika ithuba eliphezulu lokunyanga.
• I-radiosurgery yestereotactic ijolise kwi-x-reyi enamandla amakhulu kwindawo encinci. Luhlobo lonyango lwemitha, hayi inkqubo yotyando. Ingasetyenziselwa ukunciphisa okanye ukuyeka ukukhula kwamathumba ekunzima ukususa ngokuhlinzwa. Kungenziwa kwakhona ukunyanga abantu abangakwaziyo ukwenza utyando, njengabantu abadala abadala okanye abantu abagula kakhulu.

Ukususa i-acoustic neuroma kungonakalisa imithambo-luvo. Oku kunokubangela ukulahleka kokuva okanye ubuthathaka kwimisipha yobuso. Lo monakalo kunokwenzeka ukuba wenziwe xa ithumba likhulu.

I-neuroma ye-acoustic ayisiwo umhlaza. Ithumba alisasazeki kwamanye amalungu omzimba. Nangona kunjalo, inokuqhubeka nokukhula kwaye icinezele kulwakhiwo lukakayi.

Abantu abanezilonda ezincinci, ezikhula kancinci abanokufuna unyango.

Ukuva ilahleko ekhoyo ngaphambi kokuba unyango alunakubuya emva kotyando okanye i-radiosurgery. Kwiimeko zamathumba amancinci, ilahleko yokuva eyenzeka emva kotyando inokubuyela.

Uninzi lwabantu abanamathumba amancinci abayi kuba nobuthathaka obungapheliyo ebusweni emva kotyando. Nangona kunjalo, abantu abane tumors ezinkulu kunokwenzeka ukuba babe nobuthathaka obusisigxina ebusweni emva kotyando.

Iimpawu zomonakalo wemithambo-luvo njengokulahlekelwa kukuva okanye ubuthathaka bobuso zinokulibaziseka emva kweeradiosurgery.

Kwiimeko ezininzi, utyando lobuchopho lunokususa ngokupheleleyo ithumba.

Fowunela umnikezeli wakho ukuba unayo:

• Ukuphulukana nokuva ngesiquphe okanye ngokuya kusiba mandundu
• Ukukhala kwindlebe enye
• Isiyezi (i-vertigo)
