anatomical orbital floor plate

Muanatomy , orbit imhango kana socket yedehenya umo mune ziso nemaappendages aro. "Orbit" inogona kureva bony socket. Huwandu hweiyo orbit mumunhu mukuru ndeye 30 millilitres, ziso rinotora 6.5 ml yehuwandu. Zviri mukati me orbital zvinosanganisira ziso, the orbital and retrobulbar fascia, extraocular muscles, cranial nerves, tsinga dzeropa, mafuta, lacrimal gland nesaga rayo uye duct, maziso, medial uye lateral palpebral ligaments, cheki ligaments, iyo suspensory ligament, septum, ciliary tsinga uye tsinga pfupi.

Maobiti acho ane chimiro checonical kana mana-sided piramidal cavities, akavhurika muface wepakati uye anonongedza kumashure mumusoro. Chigadziko, pekisi uye madziro mana anoumba imwe neimwe orbit.

Mabhonzo madziro e orbital canal muvanhu imosaic yezvimiro zvinomwe zvakasiyana-siyana, zvinoumbwa nezygomatic bone laterally, sphenoid bone, nebapiro rayo diki richigadzira optic canal uye bapiro rayo guru richiumba lateral posterior chikamu chebhoni orbital process, iyo maxillary bone uye mediath laryferiid, inoumba madziro epakati pe orbital canal. Maseru emhepo ethmoid akatetepa zvakanyanya, uye anoumba chimiro chinozivikanwa se lamina papyracea, iyo yakanyanya kutetepa bhonzo mudehenya, uye rimwe reanowanzotyoka bhonzo mu orbital trauma.

The lateral wall inoumbwa nechemberi yezygomatic uye zvakanyanya kumashure ne orbital plate ye bapiro guru re sphenoid. Mapfupa anosangana pa zygomaticosphenoid suture. Rusvingo rweparutivi ndiyo gobvu madziro enzira, ndiyo yakanyanya kuvhurika nzvimbo, saka iri nyore kusangana nenjodzi yekukuvadzwa kwechisimba.

Inferior orbital wall fracture ndiyo yakajairika kuputsika muorbital blowout fracture, iyo inowanzokonzera matambudziko akadai seanophthalmic invagination, ocular movement disorder, diplopia uye ocular displacement, izvo zvinokanganisa zvakanyanya basa uye chitarisiko. Kune orbital blowout fractures, kuvhiyiwa kunofanirwa kuitwa nekukurumidza sezvinobvira kana intraocular invagion inopfuura 2mm uye nzvimbo yekuputsika yakakura sekusimbiswa neCT. Mukugadzirisa kwekutyoka kwe orbital, zviya zvinowanzo shandiswa zvekugadzira zvinosanganisira hydroxyapatite artificial bone, porous polyethylene polymer synthetic materials, hydroxyapatite complex uye titanium metal materials. Pakusarudza orbital kugadziridza kuisirwa zvinhu, yakanakira kuisirwa zvinhu zvinofanirwa kuve neanotevera hunhu: yakanaka biological kuenderana, nyore kuumbwa uye kuiswa mu orbit madziro akaremara zvikamu, zviri nyore kuchengetedza chimiro chayo chekutsigira orbital zviri mukati kuitira kuchengetedza yakajairika nzvimbo yeziso, inogona kutsiva iyo yakashaikwa yezviri mukati uye kukudza orbital cavity vhoriyamu, vhoriyamu CT kukwidziridzwa kufambisa postoperative yekutarisa. Sezvo titanium mesh iri nyore kuumba uye ine kugadzirisa kwakanaka, haina sensitization, carcinogenesis uye teratogenicity mukusangana nemuviri wemunhu, uye inogona kunyatsobatanidzwa nemapfupa emapfupa, epithelium uye connective tissue, saka ndiyo yakanakisisa yesimbi ine biocompatibility.

Preformed Orbital Plates akagadzirwa kubva kuCT scan data. Aya mahwendefa ane ma implants anonyatso enzanisa topographical anatomy yepasi orbital pasi uye medial madziro uye anoitirwa kushandiswa mune yakasarudzika craniomaxillofacial trauma. Preformed matatu-dimensional chimiro: Yakagadzirirwa kushoma kukotama uye kucheka izvo zvinoderedza huwandu hwenguva inodiwa kuti contour plate. Contoured plate edges: Kuti zvive nyore kupinza ndiro kuburikidza neganda rekucheka uye kushomeka kukanganiswa pakati peplate uye yakatenderedza nyama yakapfava. Yakakamurwa dhizaini: Kugadzirisa saizi yeplate kuti igadzirise orbital topografia uye kuchengetedza miganho yeplateti ine mipendero mishoma yakapinza. Rigid zone: Inodzoreredza chimiro kune posterior orbital pasi kubatsira kuchengetedza iyo chaiyo nzvimbo yepasi. mhinduro dzakakwana dzekugadzirisa pasi orbital uye kuvakazve.
