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, iyo orbital uye retrobulbar fascia, extraocular tsandanyama, cranial tsinga, tsinga dzeropa, mafuta, lacrimal gland ine sac uye duct, maziso, medial uye lateral palpebral ligaments, cheki ligaments, iyo suspensory ligament, septum. , ciliary ganglion uye pfupi ciliary tsinga.

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 emadziro emugero we orbital mumunhu mucherechedzo wezvimiro zvinomwe zvakasiyana-siyana, zvine zygomatic bone laterally, sphenoid bone, nebapiro rayo diki richigadzira optic canal uye bapiro raro guru rinoumba lateral posterior chikamu chebhoni orbital process. , iyo maxillary bone yakaderera uye yepakati iyo, pamwe chete nemapfupa e-lacrimal uye ethmoid, inoumba rusvingo rwepakati rwe 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 ne frontal process ye zygomatic and more posteriorly by 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.Kune orbital kugadzirisa kuisirwa sarudzo yezvinhu, yakanakira kuisirwa zvinhu zvinofanirwa kuve neanotevera maitiro: 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. kushayikwa kwezviri mukati me orbital uye kuwedzera iyo orbital cavity volume, vhoriyamu CT kukwidziridzwa kufambisa kutarisa kwemashure.Sezvo titanium mesh iri nyore kuumba uye ine kugadzirisa kwakanaka, haina sensitization, carcinogenesis uye teratogenicity mukusangana nemuviri wemunhu, uye inogona kunyatsobatanidzwa nefupa renyama, epithelium uye connective tissue, saka ndiyo yakanakisa simbi zvinhu zvine biocompatibility. .

Preformed Orbital Plates akagadzirwa kubva kuCT scan data.Aya mahwendefa ane ma implants anonyatso enzanisa topographical anatomy yepasi orbital yemunhu uye medial madziro uye anoitirwa kushandiswa mune yakasarudzika craniomaxillofacial trauma.Preformed matatu-dimensional chimiro: Yakagadzirirwa kushoma kukotama uye kucheka izvo zvinoderedza huwandu hwenguva inodiwa ku 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 topography uye kuchengetedza miganho yeplate yakakomberedzwa 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.
