Neuroma ke hlahala e hlahang ka har'a sheath e sireletsang ea methapo. Mofuta o tloaelehileng haholo ke acoustic neuroma e amang methapo ea kutlo ea vestibulocochlear, ke ho re mothapo oa cranial o amehang ho utloeng le kutlong ea ho leka-lekana. Le hoja li-neuromas e le lihlahala tse kotsi maemong a mangata, tse ling li ka baka mathata. Tšehetso e ka 'na ea hlokahala.

Tlhaloso ea neuroma

Neuroma ke hlahala e melang methapong. Hlahala ena e hlaha hantle ho feta liseleng tsa Schwann tse teng ka har'a sheath e sireletsang e potolohileng methapo. Ke ka lebaka lena neuroma e boetse e bitsoa schwannoma.

Mofuta o tloaelehileng haholo ke acoustic neuroma, eo hape e bitsoang vestibular schwannoma. Neuroma ena e ama methapo ea vestibular, e 'ngoe ea makala a VIII cranial nerve e amehang ho utloeng le kutloisisong ea ho leka-lekana.

E bakoa ke neuronome

Joalo ka mefuta e meng e mengata ea lihlahala, li-neuromas li na le tšimoloho e ntseng e sa utloisisoe hantle. Leha ho le joalo, liketsahalo tse ling tsa acoustic neuroma li fumanoe e le letšoao la mofuta oa 2 neurofibromatosis, lefu le bakoang ke phetoho ea liphatsa tsa lefutso.

Tlhahlobo ea neuronome

Ho ka belaelloa hore ho na le neuroma ka lebaka la matšoao a itseng a kliniki empa hape e ka fumanoa ka tšohanyetso nakong ea tlhahlobo ea bongaka. Ka sebele hlahala ena e ka ba asymptomatic maemong a mang, ke ho re ntle le matšoao a bonahalang.

Ho fumanoa ha acoustic neuroma qalong ho ipapisitse le liteko tsa kutlo tse kang:

• audiogram e etsoang maemong ohle e le ho khetholla tšobotsi ea tahlehelo ea kutlo ea acoustic neuroma;
• tympanometry eo ka linako tse ling e etsoang ho fumana hore na molumo o ka feta ka har'a eardrum le tsebe e bohareng;
• teko ea AEP, e lekanyang maikutlo a methapo ea mali mokokotlong oa boko ho tsoa ho melumo e tsoang litsebeng.

E le ho tiisa le ho tebisa lefu lena, ho etsoa tlhahlobo ea magnetic resonance imaging (MRI).

Li-neuromas ke lihlahala tse sa tloaelehang. Li emela ka karolelano pakeng tsa 5 le 8% ea lihlahala tsa boko. Ketsahalo ea selemo le selemo e batla e le 1 ho ea ho 2 ho batho ba 100.

Maemong a mang, neuroma ha e ntlafatsoe hantle 'me ha e bake matšoao a bonahalang.

Matšoao a tloaelehileng a acoustic neuroma

Kholiso ea acoustic neuroma e ka iponahatsa ka matšoao a 'maloa a tloaelehileng:

• tahlehelo ea kutlo e tsoelang pele maemong a mangata empa ka linako tse ling e ka ba ea tšohanyetso;
• tinnitus, e leng lerata kapa ho lla ka tsebeng;
• maikutlo a khatello kapa boima litsebeng;
• bohloko ba tsebe kapa tsebe;
• hlooho kapa hlooho;
• ho se leka-lekane le ho tsekela.

Tlhokomeliso: Acoustic neuroma hangata e le 'ngoe empa ka linako tse ling e ka ba mahlakore a mabeli.

Kotsi ea mathata

Li-neuromas ke lihlahala tse kotsi maemong a mangata. Leha ho le joalo, ka linako tse ling lihlahala tsena ke kankere.

Tabeng ea acoustic neuroma, hlahala ka har'a methapo ea kutlo VIII e ka baka mathata ha e ntse e hola le ho eketseha ka boholo. E atisa ho hatella methapo e meng ea cranial, e ka bakang:

• paresis ea sefahleho ka ho hatella methapo ea sefahleho (cranial nerve VII), e leng ho lahleheloa ke karolo ea litsebo tsa likoloi sefahlehong;
• trigeminal neuralgia ka lebaka la khatello ea trigeminal (cranial nerve V), e khetholloang ke bohloko bo boholo bo amang lehlakore la sefahleho.

Neuroma ha e hloke phekolo, haholo-holo haeba hlahala e nyenyane, ha e hōle ka boholo, 'me ha e bake matšoao. Leha ho le joalo, tlhokomelo ea kamehla ea bongaka e teng ho fokotsa kotsi ea mathata.

Ka lehlakoreng le leng, taolo ea neuroma e ka ba ea bohlokoa haeba hlahala e hola, e hola mme e hlahisa kotsi ea mathata. Hangata ho nahanoa ka mekhoa e 'meli ea phekolo:

• ho buuoa ho tlosa hlahala;
• radiation therapy, e sebelisang mahlaseli ho senya hlahala.

Khetho ea phekolo e itšetlehile ka mekhahlelo e mengata e kenyeletsang boholo ba hlahala, lilemo, boemo ba bophelo bo botle le ho teba ha matšoao.

Tšimoloho ea neuromas ha e hlake. Ha ho mokhoa oa thibelo o thehiloeng ho fihlela joale.
