ipleyiti yomgangatho we-anatomical orbital

Kwi-anatomy, i-orbit yi-cavity okanye i-socket ye-skull apho iliso kunye ne-appendages yalo ikhona."I-Orbit" inokubhekisa kwisokethi yamathambo.Umthamo we-orbit kumntu omdala u-30 millilitres, iliso lithatha i-6.5 ml iyonke.Imixholo ye-orbital ibandakanya iliso, i-orbital kunye ne-retrobulbar fascia, imisipha ye-extraocular, i-cranial nerves, imithambo yegazi, i-fat, i-lacrimal gland kunye ne-sac kunye nombhobho wayo, iinkophe, i-medial kunye ne-lateral palpebral ligaments, ukujonga imigqa, i-suspensory ligament, i-septum. , i-ciliary ganglion kunye ne-ciliary nerves emfutshane.

Iindlela zokujikeleza zinemilo econical okanye imingxuma enamacala amane ephiramidi, evuleleke kumgca ophakathi wobuso kwaye iphinde ibuyele entloko.Isiseko, iapex kunye neendonga ezine zenza i-orbit nganye.

Iindonga zethambo lomjelo we-orbital ebantwini yimosaic yezakhiwo ezisixhenxe ezihlukeneyo ngokweembryologically, zibandakanya ithambo le-zygomatic ecaleni, ithambo le-sphenoid, kunye nephiko lalo elincinci elenza i-optic canal kunye nephiko lalo elikhulu elenza isahlulo esingasemva secala lenkqubo ye-orbital yamathambo. , ithambo le-maxillary eliphantsi kunye ne-medially leyo, kunye ne-lacrimal kunye ne-ethmoid bones, yenza udonga oluphakathi lwe-orbital canal.Iiseli zomoya we-ethmoid zibhityile ngokugqithisileyo, kwaye zenza ulwakhiwo olwaziwa njenge lamina papyracea, esona sakhiwo samathambo esiethe-ethe kukhakhayi, kunye nelinye lawona mathambo aqhele ukuqhawuka kumonzakalo we-orbital.

Udonga olusecaleni lwenziwe yinkqubo yangaphambili ye-zygomatic nangaphezulu ngasemva ngeplate ye-orbital yephiko elikhulu le-sphenoid.Amathambo adibana kwi-zygomaticosphenoid suture.Udonga olusecaleni lolona donga lushinyeneyo lwe-orbit, ngowona mhlaba utyhilekileyo, ngoko kulula ukudibana nomngcipheko omkhulu wokwenzakala ngamandla.

Ukwaphuka kodonga olungaphantsi kwe-orbital yeyona nto ixhaphakileyo yokwaphuka kwe-orbital blowout fracture, ehlala idala iingxaki ezinje nge-enophthalmic invagination, i-ocular movement disorder, i-diplopia kunye nokufuduka kwe-ocular, echaphazela kakhulu umsebenzi kunye nenkangeleko.Ngokuphulwa kwe-orbital blowout fractures, utyando kufuneka lwenziwe ngokukhawuleza xa i-intraocular invagion ingaphezulu kwe-2mm kwaye indawo yokuphuka inkulu njengoko iqinisekisiwe yi-CT.Ekulungiseni i-orbital fracture, izinto ezenziwe ngokuqhelekileyo ezisetyenziswayo ziquka i-hydroxyapatite ithambo lokufakelwa, i-porous polyethylene polymer synthetic materials, i-hydroxyapatite complex kunye ne-titanium metal materials.Ukukhethwa kwezinto zokufakelwa kwe-orbital, izixhobo ezifanelekileyo zokufakelwa kufuneka zibe nezi mpawu zilandelayo: ukuhambelana kakuhle kwebhayoloji, ukubunjwa lula kwaye kubekwe kwiindawo zesiphene eludongeni lwe-orbit, ngokulula zikwazi ukugcina imilo yayo yenkxaso ye-orbital ukuze kugcinwe indawo eqhelekileyo yamehlo, inokutshintsha indawo. ukungabikho kwemixholo ye-orbital kunye nokwandisa umthamo we-orbital cavity, ukunyusa umthamo we-CT ukuququzelela ukujonga emva kokuhlinzwa.Ekubeni i-titanium mesh ilula ukubunjwa kwaye inokulungiswa kakuhle, ayinayo i-sensitization, i-carcinogenesis kunye ne-teratogenicity ekunxibelelaneni nomzimba womntu, kwaye inokudibaniswa kakuhle kunye nezicubu zethambo, i-epithelium kunye nezicubu ezidibeneyo, ngoko ke yeyona nto ingcono kakhulu yensimbi kunye ne-biocompatibility. .

Iipleyiti ze-Orbital ezilungiselelwe kwangaphambili ziyilwe kwidatha ye-CT scan.Ezi pleyiti zibandakanya izifakelo ezisondele kakhulu kwi-topographical anatomy yomgangatho we-orbital yomntu kunye nodonga oluphakathi kwaye zenzelwe ukusetyenziswa kwi-craniomaxillofacial trauma ekhethiweyo.Imilo esele ilungisiwe yamacala amathathu: Yenzelwe ukugoba okuncinci kunye nokusikwa okucutha ubungakanani bexesha elifunekayo kwipleyiti yecontour.Imiphetho yepleyiti ekhonkothileyo: Ukufakwa lula kwepleyiti ngokusikwa kwesikhumba kunye nokuphazamiseka okuncinci phakathi kwepleyiti kunye nezihlunu ezithambileyo ezingqongileyo.Uyilo olucandiweyo: Ukwenza ubungakanani bepleyiti ngokwezifiso ukujongana ne-orbital topography kunye nokugcina imida yeepleyiti ezijijekileyo ezinemiphetho ebukhali encinci.Indawo engqongqo: Ibuyisela imilo kumgangatho ongasemva we-orbital ukunceda ukugcina indawo echanekileyo yeglowubhu.izisombululo ezibanzi zokulungisa umgangatho we-orbital kunye nokwakhiwa kwakhona.
