igihanga gihuza isahani - ibyobo 2

Imyobo ibiri igororotse isahani igororotse, sisitemu yuzuye itanga ibintu byoroshye, byoroshye gukoresha, hamwe nibikoresho byujuje ubuziranenge.Umwanya muto wa plate-screw ya mm 0,5 ya minisiteri ntoya.Sisitemu imwe igikoresho cyo kwihuta kandi gihamye cyo gukosora amagufwa ya cranial.

Igihanga ni imiterere yamagufwa agize umutwe wintangangabo.Amagufwa ya gihanga ashyigikira imiterere yisura kandi atanga umwobo urinda.Igihanga kigizwe n'ibice bibiri: cranium na mandible.Ibi bice byombi byabantu ni neurocranium na skeleton yo mumaso irimo ibyemewe nkigufwa rinini.Igihanga kirinda ubwonko, kora intera y'amaso yombi, ukosore positon yamatwi kugirango ushoboze amajwi yerekana icyerekezo nintera y amajwi.mubisanzwe bibaho biturutse ku ihahamuka ridahwitse, kuvunika igihanga bishobora kuba ukumena muri rimwe cyangwa amwe mumagufa umunani agize igice cya gihanga cya gihanga.

Ivunika rishobora kubaho cyangwa hafi yaho ingaruka zangiritse no kwangirika kwimiterere yimbere mu gihanga nka membrane, imiyoboro y'amaraso, n'ubwonko.kuvunika igihanga bifite ubwoko bune bwingenzi, umurongo, kwiheba, diastatike, na basilar.Ubwoko bukunze kugaragara ni ukuvunika kumurongo, ariko ntukeneye kwivuza mubuvuzi. Mubisanzwe, kuvunika kwihebye mubisanzwe bitangirana amagufwa menshi yavunitse imbere yimuwe, bityo rero hakenewe ubufasha bwo kubaga kugirango usane ibyangiritse byangiritse.Kuvunika kwa Diastatike kwagura suture ya gihanga bigira ingaruka kubana bafite imyaka iri munsi yimyaka itatu.Ivunika risa riri mumagufwa munsi yumutwe.

Kuvunika igihanga.Gukubitwa inyundo, urutare cyangwa gukubitwa umutwe hamwe nubundi bwoko bwihungabana ryubusa mubisanzwe biviramo kuvunika igihanga.11% by'imvune zikomeye zo mu mutwe zibaho muri ubu bwoko bw'imvune ni imvune zagabanijwe aho amagufwa yamenetse yimuka imbere.Ivunika rya gihanga ryihebye ryerekana ibyago byinshi byo kwiyongera k'ubwonko, cyangwa kuva amaraso mu bwonko bujanjagura ingirabuzimafatizo.

Iyo habaye igikomere hejuru yo kuvunika, Kuvunika igihanga cyavunitse bizabaho.shyira mu cyuho cyimbere imbere hamwe nibidukikije, byongera ibyago byo kwandura no kwandura.Mu kuvunika kwihebye bigoye, dura mater irashwanyaguritse.Kubaga bigomba kubagwa kuvunika igihanga cyihebye kugirango ukure amagufwa mu bwonko niba bayakandagiye bakora umwobo wa burr ku gihanga gisanzwe cyegeranye.

Igihanga cy'umuntu kigabanijwemo ibice bibiri: neurocranium, ikorwa n'amagufa umunani yo mu bwoko bwa cranial ibamo kandi ikarinda ubwonko, hamwe na skelet yo mu maso (viscerocranium) igizwe n'amagufa cumi n'ane, utabariyemo na ossicles eshatu zo gutwi imbere.Kuvunika igihanga mubisanzwe bisobanura kuvunika kwa neurocranium, mugihe kuvunika igice cyo mumaso cya gihanga ari kuvunika mumaso, cyangwa niba urwasaya rwacitse, kuvunika mandibular.

Amagufa umunani ya cranial yatandukanijwe na suture: igufwa rimwe ryimbere, amagufwa abiri ya parietal, amagufwa abiri yigihe gito, igufwa rimwe rya spipoide, igufwa rimwe rya sphenoid, nigufwa rimwe rya etmoide.
