Chotupa chakumbuyo kwa fossa

Chotupa cha posterior fossa ndi mtundu wa chotupa chaubongo chomwe chili mkati kapena pansi pa chigaza.

The posterior fossa ndi malo ochepa mu chigaza, omwe amapezeka pafupi ndi ubongo ndi cerebellum. Cerebellum ndi gawo laubongo lomwe limayendetsa kayendedwe kabwino ndi kayendedwe kake. Maubongo amachititsa kuti thupi lizigwira ntchito bwino, monga kupuma.

Ngati chotupa chikukula m'dera la posterior fossa, chimatha kulepheretsa kutuluka kwa msana wam'mimba ndikupangitsa kupanikizika kwa ubongo ndi msana.

Zotupa zambiri za posterior fossa ndizo khansa zoyambirira zamaubongo. Amayambira muubongo, m'malo mofalikira kuchokera kwina kulikonse mthupi.

Zotupa za posterior fossa zilibe zifukwa zomwe zimadziwika kapena zoopsa.

Zizindikiro zimachitika molawirira kwambiri ndi zotupa za posterior fossa ndipo zimatha kuphatikiza:

• Kusinza
• Mutu
• Kusayenerera
• Nseru
• Kuyenda kosagwirizana (ataxia)
• Kusanza

Zizindikiro zochokera ku zotupa zakumbuyo kwa fossa zimachitikanso pamene chotupacho chimawononga nyumba, monga misempha yaminyewa. Zizindikiro za kuwonongeka kwamitsempha yama cranial ndizo:

• Ophunzira opunduka
• Mavuto amaso
• Yang'anani kufooka kwa minofu
• Kutaya kwakumva
• Kutaya kumverera mbali ina ya nkhope
• Mavuto akulawa
• Kusakhazikika poyenda
• Mavuto masomphenya

Kuzindikira kumatengera mbiri yakale yazachipatala ndikuwunika kwakuthupi, ndikutsatiridwa ndi mayeso ojambula. Njira yabwino kwambiri yoyang'ana posachedwa fossa ndikuyang'ana pa MRI. Kujambula kwa CT sikothandiza kuwona gawo laubongo nthawi zambiri.

Njira zotsatirazi zitha kugwiritsidwa ntchito kuchotsa chidutswa pachotupa kuti zithandizire kuzindikira:

• Tsegulani opaleshoni yaubongo, yotchedwa posterior craniotomy
• Zosokoneza bongo

Zotupa zambiri za posterior fossa zimachotsedwa ndikuchitidwa opaleshoni, ngakhale atakhala kuti alibe khansa. Muli malo ochepa kumbuyo kwa fossa, ndipo chotupacho chimatha kupitilira pazovuta ngati chikukula.

Kutengera mtundu ndi chotupacho, chithandizo chama radiation chitha kugwiritsidwanso ntchito pambuyo pochitidwa opaleshoni.

Mutha kuchepetsa kupsinjika kwa matenda polowa nawo gulu lothandizira lomwe mamembala ake amagawana zomwe akumana nazo pamavuto.

Maganizo abwino amatengera kupeza khansa koyambirira. Kutsekeka kwathunthu kwa kutuluka kwa msana wamafuta kumatha kukhala pachiwopsezo cha moyo. Ngati zotupa zimapezeka msanga, opaleshoni imatha kupangitsa kuti munthu akhale ndi moyo nthawi yayitali.

Zovuta zingaphatikizepo:

• Minyewa yama cranial
• Malangizo
• Hydrocephalus
• Kuwonjezeka kwachangu

Itanani wothandizira zaumoyo wanu ngati mumakhala ndi mutu wokhazikika womwe umachitika chifukwa cha mseru, kusanza, kapena kusintha kwa masomphenya.
