Isimila sangemuva sefossa

Isimila se-posterior fossa luhlobo lwesimila sobuchopho esisezansi noma phansi kogebhezi.

I-posterior fossa yindawo encane kugebhezi, etholakala eduze ne-brainstem ne-cerebellum. I-cerebellum iyingxenye yobuchopho obhekele ibhalansi nokunyakaza okuhlelekile. I-brainstem inesibopho sokulawula imisebenzi ebalulekile yomzimba, njengokuphefumula.

Uma isimila sikhula endaweni ye-posterior fossa, singavimba ukugeleza koketshezi lomgogodla futhi sidale ingcindezi eyengeziwe ebuchosheni nasentanyeni yomgogodla.

Izicubu eziningi ze-posterior fossa zingumdlavuza oyinhloko wobuchopho. Ziqala ebuchosheni, kunokuba zisabalale zisuka kwenye indawo emzimbeni.

Izicubu ezingemuva kwe-fossa azinazo izimbangela ezaziwayo noma izinto ezinobungozi.

Izimpawu zenzeka kusenesikhathi ngamathumba we-posterior fossa futhi zingafaka:

• Ukozela
• Ubuhlungu bekhanda
• Ukungalingani
• Isicanucanu
• Ukuhamba okungahambisani (ataxia)
• Ukuhlanza

Izimpawu ezivela kwizicubu zangemva kwe-fossa nazo ziyenzeka lapho isimila silimaza izakhiwo zasendaweni, ezinjengezinzwa ze-cranial. Izimpawu zokulimala kwezinzwa ze-cranial zifaka:

• Abafundi abahlanzekile
• Izinkinga zamehlo
• Bhekana nobuthakathaka bemisipha
• Ukulahlekelwa ukuzwa
• Ukulahlekelwa umuzwa engxenyeni yobuso
• Izinkinga zokunambitha
• Ukungazinzi lapho uhamba
• Izinkinga zombono

Ukuxilongwa kusekelwe kumlando ophelele wezokwelapha nokuhlolwa komzimba, kulandelwa ukuhlolwa kwe-imaging. Indlela enhle yokubheka i-posterior fossa nge-MRI scan. Ukuhlolwa kwe-CT akusizi ukubona leyo ndawo yobuchopho ezimweni eziningi.

Izinqubo ezilandelayo zingasetshenziswa ukususa ucezu lwesicubu ku-tumor ukusiza ngokuxilongwa:

• Vula ukuhlinzwa kobuchopho, okubizwa nge-posterior craniotomy
• I-biopsy ye-stereotactic

Izicubu eziningi ze-posterior fossa zisuswa ngokuhlinzwa, noma zingewona umdlavuza. Kunesikhala esilinganiselwe ku-posterior fossa, futhi isimila singacindezela kalula kuzakhiwo ezibucayi uma sikhula.

Ngokuya ngohlobo nobukhulu besimila, ukwelashwa ngemisebe nakho kungasetshenziswa ngemuva kokuhlinzwa.

Unganciphisa ukucindezela kokugula ngokujoyina iqembu lokusekelwa elinamalungu abelana ngokuhlangenwe nakho okuvamile nezinkinga.

Umbono omuhle uncike ekutholeni umdlavuza kusenesikhathi. Ukuvinjelwa okuphelele ekugelezeni kuketshezi lomgogodla kungaba yingozi empilweni. Uma izimila zitholakala kusenesikhathi, ukuhlinzwa kungaholela ekusindeni isikhathi eside.

Izinkinga zingafaka:

• Ama-palsies ezinzwa ze-cranial
• I-Herniation
• IHydrocephalus
• Ukwanda kwengcindezi yokungasebenzi

Shayela umhlinzeki wakho wezokunakekelwa kwezempilo uma unekhanda elijwayelekile elenzeka ngokuxaka, ukubuyisa, noma ukushintsha kombono.
