ipuleti le-anatomical orbital floor

Ku-anatomy, i-orbit iyisikhala noma isikhonkwane sogebhezi lapho iso nama-appendages akhona."I-Orbit" ingabhekisela kusokhethi yamathambo.Umthamo we-orbit kumuntu omdala ungamamililitha angama-30, iso lithatha u-6.5 ml wengqikithi.Okuqukethwe kwe-orbital kuhlanganisa iso, i-orbital ne-retrobulbar fascia, imisipha ye-extraocular, i-cranial nerve, imithambo yegazi, amafutha, i-lacrimal gland nesaka kanye nomgudu wayo, amajwabu amehlo, imigqa ye-palpebral ephakathi nendawo, hlola imigqa, i-suspensory ligament, i-septum. , i-ciliary ganglion kanye nezinzwa ezimfushane ze-ciliary.

Ama-orbit anomumo oyi-conical noma ama-pyramidal cavities anezinhlangothi ezine, avuleke phakathi kobuso bese ekhomba emuva ekhanda.Isisekelo, i-apex kanye nezindonga ezine zakha i-orbit ngayinye.

Izindonga ezingamathambo ze-orbital canal kubantu ziyi-mosaic yezakhiwo eziyisikhombisa ezihlukene ngokwe-embrologically, zihlanganisa ithambo le-zygomatic ngaseceleni, ithambo le-sphenoid, nephiko lalo elincane elakha umsele obonakalayo kanye nephiko lalo elikhulu elakha ingxenye engemuva engemuva yenqubo ye-bone orbital. , ithambo le-maxillary eliphansi futhi eliphakathi, kanye namathambo e-lacrimal kanye ne-ethmoid, akha udonga oluphakathi lwe-orbital canal.Amaseli omoya we-ethmoid mancane kakhulu, futhi akha isakhiwo esaziwa ngokuthi i-lamina papyracea, isakhiwo samathambo esintekenteke ogebhezini lwekhanda, kanye nelinye lamathambo avame ukuphuka ku-orbital trauma.

Udonga olusemaceleni lwakhiwe inqubo yangaphambili ye-zygomatic futhi ngemuva kakhulu yi-orbital plate yephiko elikhulu le-sphenoid.Amathambo ahlangana ku-zygomaticosphenoid suture.Udonga oluseceleni luwudonga oluwugqinsi kakhulu lwe-orbit, luyindawo evezwe kakhulu, ngakho kulula ukuhlangana nayo engcupheni yokuhlukumezeka kwamandla abuthuntu.

Ukuphuka kwezindonga ze-orbital okungaphansi ukuphuka okuvame kakhulu ekuqhekekeni kwe-orbital blowout, okuvamise ukubangela izinkinga ezifana ne-enophthalmic invagination, ukuphazamiseka kwe-ocular movement, i-diplopia kanye nokugudluka kwe-ocular, okuthinta kakhulu umsebenzi nokubukeka.Ngokuphuka kwe-orbital blowout, ukuhlinzwa kufanele kwenziwe ngokushesha ngangokunokwenzeka lapho ukuhlasela kwe-intraocular kungaphezu kuka-2mm futhi indawo yokuphuka inkulu njengoba kuqinisekiswe yi-CT.Ekulungiseni ukuphuka kwe-orbital, izinto zokwenziwa ezivame ukusetshenziswa zihlanganisa i-hydroxyapatite artificial bone, i-porous polyethylene polymer synthetic materials, i-hydroxyapatite complex kanye nezinto zensimbi ze-titanium.Ukuze ukhethe ukufakwa kwezinto zokulungisa i-orbital, izinto zokufakelwa ezifanele kufanele zibe nalezi zimpawu ezilandelayo: ukuhambisana okuhle kwezinto eziphilayo, ukubunjwa kalula futhi kubekwe ezingxenyeni ezinesici sodonga lwe-orbit, ezikwazi kalula ukugcina ukwakheka kwazo okuqukethwe kwe-orbital ukuze kugcinwe indawo evamile yamehlo, kungangena esikhundleni. ukuntuleka kokuqukethwe kwe-orbital nokwandisa umthamo we-orbital cavity, ivolumu yokuthuthukisa i-CT ukuze kube lula ukubhekwa kwangemva kokuhlinzwa.Njengoba i-titanium mesh ilula ukubunjwa futhi inokulungiswa okuhle, ayinakho ukuzwela, i-carcinogenesis kanye ne-teratogenicity ekuxhumaneni nomzimba womuntu, futhi ingahlanganiswa kahle nezicubu zamathambo, i-epithelium kanye nezicubu ezixhumeneyo, ngakho-ke iyinsimbi engcono kakhulu ene-biocompatibility. .

Amapuleti e-Orbital ahlelwe ngaphambilini aklanywe ngedatha ye-CT scan.Lawa mapuleti aqukethe izimila ezicishe zisondele eduze kwe-topographical anatomy yephansi le-orbital yomuntu kanye nodonga oluphakathi futhi ahloselwe ukusetshenziswa ekuhlukumezekeni okukhethekile kwe-craniomaxillofacial.Umumo owenziwe ngaphambilini wezinhlangothi ezintathu: Idizayinelwe ukugoba okuncane nokusika okunciphisa isikhathi esidingekayo ukuze i-contour plate.Imiphetho yepuleti eliyindilinga: Ukuze kube lula ukufaka ipuleti ngokusika isikhumba kanye nokuphazamiseka okuncane phakathi kwepuleti nezicubu ezithambile ezizungezile.Idizayini ehlukanisiwe: Ukwenza ngendlela oyifisayo usayizi wepuleti ukuze ubhekane ne-orbital topography kanye nokugcina imingcele yepuleti elijikijelwe elinemiphetho ebukhali emincane.Indawo eqinile:Ibuyisela umumo endaweni engemuva ye-orbital ukusiza ukugcina indawo efanele yomhlaba.izixazululo ezibanzi zokulungisa nokwakha kabusha i-orbital floor.
