 ngokusho kwesakhiwo se-orbital orbital wall wall design, gwema ngempumelelo umgodi we-optic nezinye izakhiwo ezibalulekile

 i-anatomy, idizayini ebunjiwe, ngangokunokwenzeka ukunciphisa umthwalo womsebenzi we ekubumbeni, ukubuyisela ngempumelelo ukuqhubeka komgogodla wethambo, kusindisa i isikhathi sokusebenza, ukunciphisa ukuhlukumezeka kokuhlinzwa, kuncane kokuhlinzwa izinkinga.

 udonga lwe-orbital oluphansi lucekeceke njengephepha, ngakho-ke, gcina indawo elukhuni engemuva kwe-orbital floor titanium mesh. Siza ukusetha kabusha izicubu ze-eyeball kanye namafutha aboshiwe, ubuyisele ivolumu yomgogodla we-orbital nokunyakaza kwamehlo, kuthuthukise ukudamba kwamehlo nediplopia.

Ku-anatomy, i-orbit iyimbobo noma isokhethi logebhezi lapho iso nezinto zalo ezihlanganisiwe zikhona. "I-Orbit" ingabhekisa esokeni lamathambo. Umthamo we-orbit kumuntu omdala ungamamililitha angama-30, iso lihlala ku-6.5 ml wengqikithi. Okuqukethwe kwe-orbital kufaka iso, i-orbital ne-retrobulbar fascia, imisipha engaphezulu, imisipha ye-cranial, imithambo yegazi, amafutha, indlala ye-lacrimal enesikhwama sayo nomgudu, amajwabu amehlo, imisipha ye-palpebral medial kanye ne-lateral, hlola i-ligaments, i-ligament esusayo, i-septum , i-ciliary ganglion nezinzwa ezimfushane ze-ciliary.

Imizila iyisimo esiyindilinga noma izimbotshana ezinamacala amane ezinamaphiramidi, ivuleke phakathi nobuso bese ikhomba emuva ekhanda. Isisekelo, isiqongo nezindonga ezine zakha ukuzungeza ngakunye.

Izindonga ze-Bony zomsele we-orbital ebantwini ziwumbala wezakhiwo eziyisikhombisa ezihlukile zombungu, eziqukethe ithambo le-zygomatic ngokuhamba kwesikhathi, ithambo le-sphenoid, nephiko lalo elincane elenza umsele we-optic nephiko lalo elikhulu elenza ingxenye engemuva engemuva yenqubo ye-bony orbital , ithambo le-maxillary eliphansi neliphakathi, okuhambisana namathambo e-lacrimal ne-ethmoid, akha udonga oluphakathi lomsele we-orbital. Amaseli omoya e-ethmoid mancane ngokwedlulele, futhi akha isakhiwo esaziwa njenge-lamina papyracea, isakhiwo esibucayi kakhulu samathambo kugebhezi, nelinye lamathambo avame ukwephuka ekuhlukumezeni komzimba.

Udonga lwe-lateral lwakhiwa ngenqubo engaphambili ye-zygomatic nangaphezulu ngemuva kwepuleti le-orbital lephiko elikhulu le-sphenoid. Amathambo ahlangana ku-zygomaticosphenoid suture. Udonga lwe-lateral ludonga olujiyile kakhulu lwe-orbit, luyindawo evezwe kakhulu, okulula kakhulu ukuhlangabezana nayo engozini enkulu yokuhlukumezeka kwamandla.

Ukwephuka kodonga lwe-orbital oluphansi ukwaphuka okuvame kakhulu ekuqhekekeni kokushaywa yi-orbital, okuvame ukudala izingqinamba ezinjenge-enophthalmic invagination, i-ocular movement disorder, i-diplopia kanye ne-ocular displacement, ethinta kakhulu umsebenzi nokubukeka. Ngokuqhekeka kokuqhuma kwe-orbital, ukuhlinzwa kufanele kwenziwe ngokushesha okukhulu lapho ukufakwa kwe-intraocular kungaphezulu kwe-2mm futhi indawo yokuqhekeka inkulu njengoba iqinisekiswe yi-CT. Ekulungisweni kokuqhekeka kwe-orbital, izinto zokwenziwa ezisetshenziswa kakhulu zifaka phakathi i-hydroxyapatite bone bone, porous polyethylene polymer zokwenziwa, i-hydroxyapatite eyinkimbinkimbi nezinto zensimbi ze-titanium. Okokukhetha okokufaka kokulungiswa kwe-orbital, izinto ezifakwayo ezifanele kufanele zibe nezici ezilandelayo: ukuhambisana okuhle kwebhayoloji, okulula ukwakheka nokubekwa ezingxenyeni zodonga lwesici se-orbit, ezikwazi kalula ukugcina ukwakheka kokusekelwa kokuma komumo ukuze kugcinwe ukuma kwamehlo okujwayelekile, kungangena esikhundleni ukungatholakali kokuqukethwe kwe-orbital futhi kukhulise ivolumu ye-orbital cavity, isithuthukisi sevolumu ye-CT ukwenza lula ukubonwa kwangemva kokusebenza. Njengoba i-titanium mesh kulula ukuyilungisa futhi inokulungiswa okuhle, ayinakho ukuzwela, i-carcinogenesis kanye ne-teratogenicity ekuxhumaneni nomzimba womuntu, futhi ingahlanganiswa kahle nezicubu zethambo, i-epithelium nezicubu ezixhumanayo, ngakho-ke iyinsimbi yensimbi ehamba phambili enokuhambisana .

Amapuleti we-Orbital Preformed aklanyelwe kusuka kudatha ye-CT scan. Lezi zingcwecwe ziqukethe okufakwa okucishe kufane nendawo yokwakheka komhlaba womuntu orbital floor nodonga oluphakathi futhi kuhloselwe ukusetshenziselwa ukuhlukunyezwa okukhethiwe kwe-craniomaxillofacial. Ukwakheka okwenziwe kathathu okwenziwe kwangaphambili: Yakhelwe ukugoba nokusika okuncane okunciphisa isikhathi esidingekayo ukwenza ipuleti. Imiphetho yepuleti enqunyelwe: Ukufakwa kwepuleti okulula ngokusebenzisa ukusika kwesikhumba nokuphazamiseka okuncane phakathi kwepuleti nezicubu ezithambile ezizungezile. Idizayini ehlukanisiwe: Ukwenza ngokwezifiso usayizi wepuleti ukubhekana nokwakheka komhlaba kwe-orbital nokugcina imingcele yamapuleti enamaphutha anemiphetho ebukhali encane. Indawo eqinile: Ibuyisela ukwakheka kusitezi sangemuva se-orbital ukusiza ukugcina indawo elungile yomhlaba. izixazululo ezibanzi zokulungiswa phansi kwe-orbital nokwakhiwa kabusha.
