saxan sagxada orbital anatomical

Anatomy, orbit-ku waa godka ama godka madaxa oo ay ku yaalliin isha iyo qalabkeeda."Orbit" waxay tixraaci kartaa godka lafaha.Mugga wareegga wareegga ee bini'aadamka qaangaarka ah waa 30 millilitir, isha waxay ku jirtaa 6.5 ml guud ahaan.Waxyaabaha ku jira orbital waxay ka kooban yihiin isha, orbital iyo retrobulbar fascia, murqaha ka baxsan, neerfaha cranial, xididdada dhiigga, baruurta, qanjidhada lacrimal oo leh kiishad iyo tubbada, indhaha daboolka, seedaha palpebral dhexdhexaad ah iyo lateral, hubi seedaha, seedaha ganaax, septum , ganglion ciliary iyo dareemayaasha ciliary gaaban.

Wareegyadu waa qaab tol ah ama godadka Ahraamta afar geesoodka ah, oo u furan dhexda wejiga oo dib ugu celi madaxa.Saldhig, daraf iyo afar darbi ayaa ka kooban wareeg kasta.

Darbiyada lafaha ee kanaalka orbital ee bini'aadamka waa mosaic ka kooban todoba qaab-dhismeedka embriyaha kala duwan, oo ka kooban lafta zygomatiga ah, lafta sphenoid, oo leh baalkeeda yar ee samaynta kanaalka indhaha iyo baalkeeda weyn ee samaynta qaybta dambe ee habka lafaha lafaha. , lafta maxillary oo ka hoosaysa iyo dhexdhexaad ahaan taas oo ay weheliso lafaha lacrimal iyo ethmoid, oo sameeya gidaarka dhexe ee kanaalka orbital.Unugyada hawada ethmoid aad bay u dhuuban yihiin, waxayna sameeyaan qaab-dhismeed loo yaqaanno papyracea lamina, oo ah qaabka ugu jilicsan lafta madaxa, iyo mid ka mid ah lafaha ugu badan ee jaban ee dhaawaca orbital.

Derbiga dambe waxaa sameeyay habka hore ee zygomatic iyo in ka sii danbeysa by saxanka orbital ee garabka weyn ee sphenoid.Lafaha waxay ku kulmaan tolida zygomaticosphenoid.Derbiga dambe waa gidaarka ugu dhumuc weyn meeraha, waa kan ugu daboolan, si fududna loola kulmo dhaawac xoog leh oo aad ugu nugul.

Burburka gidaarka hoose ee orbital jabka ayaa ah jabka ugu badan ee jabka afuufka orbital, kaas oo inta badan sababa dhibaatooyin ay ka mid yihiin invagination enopthalmic, cillad dhaqdhaqaaqa indhaha, diplopia iyo barakicinta indhaha, taas oo si weyn u saamaysa shaqada iyo muuqaalka.Jabka dillaaca orbital-ka, qalliin waa in la sameeyaa sida ugu dhakhsaha badan marka xuubka intracular ka badan yahay 2mm iyo aagga jabku ka weyn yahay sida uu xaqiijiyay CT.Dayactirka jabka orbital, alaabta macmalka ah ee sida caadiga ah loo isticmaalo waxaa ka mid ah hydroxyapatite lafo macmal ah, maaddooyinka synthetic polyetylen polyetylen, kakan hydroxyapatite iyo biraha titanium.Wixii dayactirka orbital doorashada alaabta maqaar-galaha, qalabka maqaar-galaha ugu fiican waa in ay leeyihiin sifooyinka soo socda: waafaqid bayooloji wanaagsan, fududahay in la qaabeeyo oo lagu meeleeyaa qaybaha cillad darbiga orbit, si fudud u awoodaan si ay u sii xajistaan ​​ay taageerada qaab content orbital si ay u ilaaliyaan booska isha caadiga ah, bedeli kartaa maqan ee ka kooban orbital iyo ballaariyo mugga godka orbital, mugga CT xoojinta si ay u fududeeyaan fiirsashada postoperative.Maaddaama mesh titanium ay fududahay in la qaabeeyo oo ay leedahay hagaajin wanaagsan, ma laha dareen-celin, kansarka iyo teratogenicity ee xiriirka jidhka bini'aadamka, waxaana si fiican loogu dari karaa unugyada lafaha, epithelium iyo unugyo isku xiran, sidaas darteed waa birta ugu fiican ee biocompatibility. .

Taarikada Orbital Preformed waxaa laga soo qaatay xogta CT scan.Taarikadani waxay ka kooban yihiin implants kuwaas oo si dhow u qiyaasa anatomy topographical ee sagxada orbital ee bini'aadamka iyo gidaarka dhexe waxaana loogu talagalay in loo isticmaalo dhaawaca craniomaxillofacial ee xulashada ah.Qaab saddex-geesood ah oo hore loo diyaariyey: Loogu talagalay foorarsi yar iyo goyn taas oo yaraynaysa wakhtiga loo baahan yahay in lagu sawiro saxanka.Cidhifyada saxan-ka-kooban: Si sahlan oo saxan loo geliyo jeexitaanka maqaarka iyo faragelinta yar ee u dhaxaysa saxanka iyo unugga jilicsan ee ku hareeraysan.Nakhshad Qaybsan: Si loo habeeyo cabbirka saxanka si wax looga qabto muuqaal-qurxinta orbital iyo in la ilaaliyo xudduudaha saxannada la isku dhejiyay ee leh cidhifyo fiiqan oo yar.Aagga qallafsan: Waxay dib ugu soo celisaa qaabka dabaqa orbital ee dambe si ay uga caawiso ilaalinta booska saxda ah ee adduunka.xalal dhamaystiran oo loogu talagalay dayactirka sagxada orbital iyo dib u dhiska.
