Pa opaleshoni ya cranio-maxillofacial (CMF), kulondola ndi kukhazikika ndikofunikira kuti mafupa akhazikike bwino komanso zotsatira za nthawi yayitali za odwala. Pakati pa machitidwe osiyanasiyana okonzekera omwe alipo lero, ndiCMF kudzibowola screw 1.5 mmtitaniyamu amaimaperekani ngati njira yabwino yothetsera ntchito zofewa komanso zazing'ono.
Amapangidwira kuti asamavutike pang'ono komanso kukhazikika kodalirika, zomangira zazing'onozi zimagwiritsidwa ntchito kwambiri pomanganso orbital, ma fractures a mandibular, ndi maopaleshoni ena ovuta kwambiri amaso pomwe kukula ndi magwiridwe antchito ndizofunikira.
Ubwino wa Kukula Kwakukulu: Ndiwoyenera kwa Mafupa Ang'onoang'ono ndi Malo Owoneka bwino a Anatomical
1.5 mm titaniyamu yodzibowolera yodzibowoleza screw imapereka mwayi wodziwika pama opaleshoni ang'onoang'ono. M'mimba mwake yaying'ono imachepetsa chiwopsezo cha kugawanika kwa mafupa ndikuchepetsa kuvulala kwa opaleshoni, ndikupangitsa kuti ikhale yoyenera kwambiri kwa fupa lopyapyala la cortical kapena tizidutswa tating'ono tating'ono tomwe timakumana ndi makoma ozungulira, mafupa amphuno, kapena milandu ya CMF ya ana.
Poyerekeza ndi zomangira zazikulu, kapangidwe ka 1.5 mm kumafuna kuchotsedwa kwa mafupa pang'ono pakubowola, kusunga umphumphu wa mafupa ndi kupereka magazi. Kukula kwapang'onopang'ono kumeneku kumathandizira kuchira mwachangu komanso kumachepetsa kusapeza bwino pambuyo pa opaleshoni kwa odwala. Kuphatikiza apo, kudzibowola kumathetsa kufunika koboola kale, kufupikitsa nthawi yogwira ntchito komanso kupititsa patsogolo opaleshoni m'malo otsekeka.
Kugwirizana ndi Kukhazikika ndi CMF Locking Plates
Imodzi mwa mphamvu zazikulu za 1.5 mm zomangira zodzibowola zagona pakulumikizana kwake kopanda msoko ndi mbale zokhoma za CMF titaniyamu. Akagwiritsidwa ntchito limodzi, amapanga zokhazikika komanso zotetezeka zomwe zimalepheretsa kumasuka, ngakhale pansi pa zovuta zamakina kapena m'magawo am'mafupa monga mandible.
Msonga wodzibowoleza wodzibowolera wowotchera wowotcherayo umatsimikizira kukwanira bwino komanso kodalirika polumikizana ndi mabowo a mbale, kusungitsa kukanikizana kofanana ndi fupa-mbale. Izi zimabweretsa kufalikira kwa katundu ndikuwongolera kukana kwa micro-movement. Kaya amagwiritsidwa ntchito pokonza zolimba m'ming'alu yaing'ono kapena njira zokonzanso zomwe zimafuna kukhazikika kwa contour, kuphatikiza kumeneku kumathandizira zodziwikiratu zachipatala komanso kukhulupirika kwa makina.
Ntchito Zachipatala: Zotsatira Zotsimikiziridwa mu Opaleshoni ya CMF
CMF self-bowola screw 1.5 mm titaniyamu yawonetsa zotsatira zabwino kwambiri pazowonetsa zosiyanasiyana zamankhwala.
Pansi pa Orbital ndi Kumanganso Khoma
Mu fractures orbital, kumene makulidwe a mafupa ndi malo ochepa, dongosolo la 1.5 mm limapereka njira yothetsera vutoli. Madokotala amatha kumangirira ma meshes opyapyala a titaniyamu kapena mbale kuti abwezeretse mphamvu ya orbital popanda kuyika pachiwopsezo kuyika kwa minofu kapena kusokonekera.
Mandibular ndi Maxillary Mini-Fractures
Kwa fractures yaing'ono kapena pang'ono ya mandibular, makamaka m'madera a ana kapena anterior, screw's compact profile imatsimikizira kukhazikika kokwanira ndikuchepetsa kukwiya kwa minofu yofewa.
Zygomatic ndi Nasal Bone Fixation
Pakuvulala kwapakatikati, zomangira za 1.5 mm zimathandizira kuyikanso kolondola kwa zygomatic arch ndi mafupa a m'mphuno, kusunga symmetry ndi kubwezeretsanso magwiridwe antchito ndi magawo ochepa a hardware.
Ntchito zachipatalazi zikuwonetsa kusinthasintha kwa dongosololi komanso kukonda komwe kukukulirakulira pakati pa maopaleshoni a kachitidwe kakang'ono kamene kamaphatikiza chitetezo, mphamvu, ndi magwiridwe antchito.
Titaniyamu Yapamwamba Kwambiri Kwa Nthawi Yaitali Yogwirizana ndi Biocompatibility
Zopangidwa kuchokera ku titaniyamu yachipatala, zomangira zodzibowola izi zimatsimikizira kudalirika kwa biocompatibility ndi kukana dzimbiri. Makhalidwe a Titanium opepuka komanso osagwiritsa ntchito maginito amapangitsa kuti ikhale yoyenera ma implants a CMF, kuthandizira kuphatikizika kwa osseointegration ndikupewa kuyabwa kapena kutupa. Ulusi wopangidwa mwaluso umapangitsa kuti ukhale wolimba komanso wosasunthika, ndikuwonetsetsa kukhazikika kwanthawi yayitali ngakhale m'mafupa ovuta.
Mapeto
CMF self-bowola screw 1.5 mm titaniyamu imayimira kusinthika kwaukadaulo wa mini fixation - kupatsa madokotala maopaleshoni moyenera pakati pa mapangidwe ang'onoang'ono ndi mphamvu zamakina odalirika. Kugwirizana kwake ndi mbale zokhoma za CMF, kuyanjana kwabwino kwambiri, komanso zotsatira zotsimikizika pamachitidwe a orbital ndi mandibular zimapangitsa kuti ikhale chisankho chokondedwa pamachitidwe olimba okonzanso.
Ku Shuangyang, timakhala okhazikika pakupanga ndi kupanga makina apamwamba a CMF, kuphatikizapo zomangira zodzibowola ndi zomangira zokhazokha, mbale zokhoma, ndi zothetsera makonda zogwirizana ndi zomwe mukufuna opaleshoni.
