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 iquka 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, i-check ligaments, i-suspensory ligament, i-septum, i-ciliary nerve kunye ne-ciliary.

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 yi-mosaic 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 senkqubo ye-orbital ye-bony, ithambo le-maxillary kunye ne-medially ecrimally, yenza udonga oluphakathi kumjelo we-orbital. 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 kwezinto zokulungisa i-orbital, izinto ezifanelekileyo zokufakelwa kufuneka zibe nezi mpawu zilandelayo: ukuhambelana kakuhle kwezinto eziphilayo, ukubunjwa lula kwaye kubekwe kwiindawo ezinesiphako sodonga lwe-orbit, ngokulula zikwazi ukugcina imilo yayo yenkxaso ye-orbital ukuze kugcinwe indawo yesiqhelo yamehlo, inokutshintsha indawo engekhoyo imixholo ye-orbital kunye nokwandisa umthamo we-orbital cavity, ukunyusa umthamo we-CT ukuququzelela ukuqwalaselwa emva kokuhlinzwa. Ekubeni i-titanium mesh ilula ukumila 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 iyona 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 engaphambili i-dimensional-dimensional: Yenzelwe ukugoba okuncinci kunye nokusikwa okucutha ixesha 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.
