Kwaziwa nangokuthi: i- acoustic neurinoma, i-vestibular schwannoma, i-tumor
I-Acoustic neuroma yintsholongwane echaphazelekayo echaphazela iimbilini ezithatha ukusuka kwindlebe yangaphakathi ukuya kwingqondo. Izondlo eziqhelekileyo zempilo zihlanganiswe ngoluhlu lweeseli ezibizwa ngokuba yiStnn cells ezisebenza ngendlela efanayo ukuba i-rubber okanye ipulasitiki yokugubha kwimbane zombane isebenza; ukubonelela kunye nokuxhasa imiphumo yesigulane.
Xa la maseli eqala ukukhula kwaye atyuke ngezinga elingavamile, i-neuroma ye-acoustic iyakwenzeka.
Ukwanda kwe-Acoustic Neuroma
I-Acoustic neuroma ivela kuphela kwi-2 kwabangama-100,000 abantu xa kungekho nanye iimeko zokucima. Isizathu esingaqhelekanga esingaqhelekanga sokuvelisa i-neuroma ye-acoustic yi-traumatic trauma kwaye kukho inkolelo yokuba imisebe ephantsi ye-dose kwiinkqubo zentloko nentamo emncinane inokunyusa ingozi. Nangona kubekho amahemuhemu ukuba ukusetyenziswa kwefowuni yexesha elide kunokunxulumana ne-acoustic neuroma, uphando aluxhasi le rhweba.
I-Acoustic neuroma ixhaphake kakhulu xa une-neurofibromatosis hlobo 2 (NF2). Ukuba ufumene ukuba unesifo se-NF2, umngcipheko wakho ukwandisa kubantu abayi-2 kwabangama-10,000. Kwimeko apho, i-neuroma yama-acoustic ihlala iphakathi kweminyaka eyi-50 ukuya kwe-70 ubudala.
Iimpawu ze-Acoustic Neuroma
I-Acoustic neuroma inqanda umsebenzi oqhelekileyo weentsholongwane ezijongene nokuva kunye nokulinganisela .
Iimpawu ze-acoustic neuroma ziquka:
- ukulahlekelwa kweendlebe kwicala elinye
- vertigo
- tinnitus
Ukuba i-tumor ixinzezela kwi-nerial facial, impawu zingabandakanya:
- ebusweni buso
- ubuthathaka obusweni
- ukukhubazeka komzimba
Nangona i-neuroma ye-acoustic iyimvamisa ekhula ngokukhawuleza, ukuba ayinakuphulukiswa inokuba yinto enkulu kangangokuba iqhutyana nezakhi zobuchopho ezibalulekileyo kwaye ingaba yingozi yokuphila.
Ukuxilongwa
Ukuxilongwa kwe-acoustic neuroma kunokuba nzima (ngakumbi ukuba i-tumor iyincinci) kuba iimpawu zihambelana nezinye iingxaki zeendlebe zangaphakathi. Ezinye zezona mvavanyo eziluncedo ezisetyenziselwa ukuxilonga le meko zi:
- I-Audiogram
- CT scan
- MRI
I-MRI yindlela ekhethiweyo yokuvavanya njengoko inokuba luncedo ekuboneni izicubu ezincinci (2 mm ngobukhulu okanye obukhulu) xa zisetyenziswe ngokungafani kwe-gadolinium. I-CT ingasetyenziswa ekuboneni izicubu ezinkulu kune-2 cm.
Unyango
Uphulo luvame ukuquka ukukhutshwa ngokugqithisileyo kwesisu. Nangona kunjalo, ukuba i-tumor isancinci kwaye ingabonakali, isigulane kunye nodokotela angakhetha ukujonga ilonda. Kwakhona kunjalo ukuba isigulane asiyena umviwa ofanelekileyo otyando ezifana nezigulane ezisebekhulile ezineembali zentliziyo kunye nesifo sengqondo. Ukugqitywa kokugqithwa kwe-tumor kuneengozi ezininzi kubandakanye umngcipheko wokuba iimbulunga ezijikeleze isisu sinokulimala. Oku kuyinyaniso ngokukodwa ukuba i-tumor ikhulu kakhulu. Ezinye iindlela zokwenza unyango ziquka unyango lwe-radiation okanye i-radiosurgery. Zombini ezi zonyango zijolise ekunciphiseni ubukhulu besisu.
Ngomzamo wokunciphisa umngcipheko wokulimaza iinambuzane ezijikelezayo, abanye oogqirha banokukhetha ukwenza utyando oluthile ukuze kususwe uninzi, kodwa alukho konke, lwesisu.
Ukulandela utyando, unyango lwe-radiation olujoliswe kuzo luyakwenziwa ukutshabalalisa lonke i-tumor.
Ukungaphumeleli ukunyanga i-acoustic neuroma kunokukhokelela kwiindlebe ezingapheliyo kunye neengxaki zokulinganisela. Ukuba i-tumor encinci, ugqirha wakho angathanda ukulibazisa ngokugqithiseleyo ukukhipha isisu, kwaye uya kulandela i-MRI nganye inyanga ezi-6 ukuya kwezi-12. Ukulahla unyango ixesha elide nangona kungabangela umonakalo ongenakuguquka. Ukuba nencoko evulekileyo malunga nomngcipheko kunye nenzuzo yokulibazisa utyando kunye nodokotela wakho ogqirha unyanzelekile ngaphambi kokuba wenze naziphi na izigqibo.
