icyapa cya orbital hasi

Muri anatomy, orbit ni cavit cyangwa sock ya gihanga ijisho hamwe nimigereka yayo. "Orbit" irashobora kwerekeza kumagufa. Ingano ya orbit mubantu bakuze ni mililitiro 30, ijisho rifata ml 6.5 zose hamwe. Ibiri muri orbital bigizwe nijisho, fassiya ya orbital na retrobulbar, imitsi idasanzwe, imitsi ya cranial, imitsi yamaraso, ibinure, glande ya lacrimal hamwe numufuka wacyo hamwe numuyoboro wacyo, ijisho, ijisho, imitsi ya palpebral ligaments, kugenzura ligaments, ligamente ihagarikwa, septum, ciliary ganglion na ciliary nili.

Ibizenguruka ni imiterere ihuriweho cyangwa impande enye za piramide, zifunguye mumaso hagati hanyuma zerekeza mumutwe. Shingiro, apex ninkuta enye zigize buri orbit.

Urukuta rw'amagufwa rw'umuyoboro wa orbital mu bantu ni mozayike y’imyubakire irindwi itandukanye, igizwe n'amagufwa ya zygomatike nyuma, igufwa rya sphenoide, hamwe n'ibaba ryayo rito rigizwe n'umuyoboro wa optique hamwe n'ibaba ryacyo rinini rigize igice cy'inyuma cy'uruzitiro rw'amagufwa, amagufwa ya maxillary hasi cyangwa hagati y'amagufwa ya lacrimal na etmoid. Ingirabuzimafatizo ya Ethmoid ni ntoya cyane, kandi ikora imiterere izwi nka lamina papyracea, imiterere yamagufwa yoroheje cyane mu gihanga, hamwe nimwe mumagufwa akunze kuvunika cyane mu ihungabana rya orbital.

Urukuta ruzengurutse rugizwe nuburyo bwimbere bwa zygomatike kandi inyuma yinyuma ya plaque ya orbital yamababa manini ya sphenoide. Amagufwa ahurira kuri zygomaticosphenoid suture. Urukuta ruzengurutse ni urukuta runini cyane rwa orbit, ni ubuso bugaragara cyane, ku buryo byoroshye guhura n’ibibazo byoroshye guhura n’ihungabana ridahwitse.

Kuvunika urukuta rwa orbital ni ukuvunika cyane mu kuvunika kwa orbital, akenshi bitera ingorane nko gutera enophthalmic invagination, ocular movement disorder, diplomopiya no kwimura ocular, bigira ingaruka zikomeye kumikorere no kugaragara. Kuvunika kwa orbital, kubagwa bigomba gukorwa vuba bishoboka mugihe igitero cyo munda kirenze 2mm kandi agace kavunitse ni nini nkuko byemejwe na CT. Mu gusana kuvunika kwa orbital, ibikoresho bisanzwe bikoreshwa birimo hydroxyapatite igufwa ryubukorikori, ibikoresho bya sintetike ya polyethylene polymer, ibikoresho bya hydroxyapatite nibikoresho bya titanium. Kuburyo bwa orbital gusana ibikoresho byahisemo, ibikoresho byiza byatewe bigomba kuba bifite ibi bikurikira: guhuza neza ibinyabuzima, byoroshye gushushanya no gushyirwa mubice byangiritse byurukuta rwa orbit, byoroshye kugumana imiterere yabyo bifasha ibintu bya orbital kugirango bigumane umwanya wamaso asanzwe, birashobora gusimbuza ibura ryibintu bya orbital no kwagura ubwinshi bwimyanya ndangagitsina, ubwiyongere bwa CT kugirango byoroherezwe kwitegereza nyuma yibikorwa. Kubera ko inshusho ya titanium yoroshye kuyikora kandi ikagira neza, ntabwo ifite sensibilisation, kanseri ndetse na teratogenicite ihura numubiri wumuntu, kandi irashobora guhuzwa neza nuduce twamagufwa, epitelium hamwe nuduce duhuza, bityo rero nibikoresho byiza byicyuma hamwe na biocompatibilité.

Ibyapa bya Orbital byateguwe byakozwe kuva CT gusikana amakuru. Aya masahani agizwe no gushiramo hafi ya anatomiya ya topografiya ya etage ya orbital yumuntu hamwe nurukuta rwagati kandi igenewe gukoreshwa muguhungabana kwa craniomaxillofacial. Imiterere yuburyo butatu: Yashizweho kugirango yunamye ntoya kandi ikata igabanya igihe gikenewe kugirango isahani. Impande zometseho isahani: Kugirango ushiremo isahani yoroshye ukoresheje uruhu no kutivanga hagati yisahani hamwe nuduce tworoshye. Igishushanyo mbonera ： Guhindura ubunini bwa plaque kugirango ukemure imiterere yubutaka bwa orbital no kubungabunga imbago zisahani zifite impande ntoya. Agace gakomeye ： Kugarura imiterere hasi yinyuma ya orbital kugirango ifashe kugumana umwanya mwiza wisi. ibisubizo byuzuye byo gusana hasi ya orbital no kwiyubaka.
