kutseka maxillofacial mini rectangle mbale

Locking mbale ndi chipangizo chomangirira chothyoka chokhala ndi bowo lotsekera. Chotsekera mbale chimathandiza fupa kuti ligwirizane kwambiri ndi mbale, kupangitsa kuti nthambi yodulidwayo ikhale yolimba ikayikanso.

Mimba yotsekera idagwiritsidwa ntchito koyamba zaka 20 zapitazo mu opaleshoni ya msana ndi maxillofacial kuti akhazikitse fractures ndikuchepetsa kufalikira kwa minofu yofewa komanso kuvulala.

Chotsekera mbale ndi chipangizo chomangira chophwanyika chokhala ndi mabowo opindika momwe mbaleyo imagwira ntchito ngati chipangizo cholumikizira ngongole ikayikidwa skrew yokhala ndi mutu wa ulusi. Mabowo okhoma komanso osatseka atha kuperekedwa kuti alowetsemo zidindo zosiyanasiyana. kulungamitsidwa muzitsulo zokhazikika (zokhazikika) Zomangira kapena bawuti kwenikweni ndi mbale yokhoma.Kukhazikika kwa chitsulo sikutengera kugundana kwa fupa kuti zizindikire kulumikizana, koma zimatengera kutsekera kwa mbale yachitsulo yomwe.A kusiyana kwina kungasiyidwe pakati pa mbale yachitsulo ndi fupa pamwamba, zomwe zimathetsa vuto la kukhudzana kolemera pakati pa mbale yachitsulo ndi fupa, ndipo kumapangitsa kuti magazi aziyenda bwino komanso kukula ndi kuchira kwa periosteum.Kusiyanitsa kwakukulu kwa biomechanical pakati pa mbale miyambo zitsulo ndi mbale chikhalidwe zitsulo ndi kuti yotsirizira amadalira mikangano mphamvu pa fupa-mbale mawonekedwe compress fupa.

The locking screw ndi self-tapping screw ndipo ingagwiritsidwe ntchito popanda kugogoda kapena kubowola fupa. Palibe kukakamiza pakati pa mbale yachitsulo ndi fupa la fupa, kotero palibe kupanikizika pa periosteum, kuti muteteze kuperekedwa kwa magazi a periosteum. Pankhani ya njira ya opaleshoni, imatha kukwaniritsa zofunikira za opareshoni yocheperako, ndipo imatha kuteteza bwino magazi am'deralo a fracture, kotero kuti ntchito yolumikizira mafupa sikufunika.Kukhazikitsa kwamkati kwamkati kumakhala zotanuka.Pamaso pa katundu, pali kukondoweza kupsinjika pakati pa midadada yosweka, yomwe imathandizira kupanga ma callus ndi machiritso a fracture.

Pambuyo maxillofacial fracture, makamaka kuchepetsa ndi fixation.Chizindikiro chofunikira cha kuchepetsa nsagwada kuthyoka ndi kubwezeretsa yachibadwa occlusal ubale chapamwamba ndi m'munsi mano, ndiko kuti, kukhudzana kwambiri kukhudzana mano.Otherwise izo zidzakhudza kuchira mastication ntchito. Pambuyo pa kuchira kwa fracture.Pali njira zitatu zodziwika zobwezeretsanso:

1.Kuchepetsa kwachangu: kumayambiriro kwa kuphulika kwa nsagwada, gawo la fracture limakhala logwira ntchito, ndipo gawo la fracture losamutsidwa likhoza kubwezeretsedwa ku malo abwino ndi dzanja.

Kuchepetsa kwa 2.Traction: pambuyo pa kusweka kwa nsagwada, patatha nthawi yaitali (kuposa masabata atatu a maxilla, masabata oposa anayi a mandible), kupasuka kumakhala ndi gawo la machiritso a minofu ya fibrous, kuchepetsa kwamanja sikupambana, njira kuchepetsa kukhudzika angagwiritsidwe ntchito.The mandibular kuthyoka Mipikisano cholinga nsagwada traction, ali mu mandibular fupa ali kusamutsidwa wa fracture gawo la masungidwe a kachigawo mano Chipilala splint, ndiyeno pakati pa mano Chipilala chipwirikiti ndi maxillary, ndi gulu laling'ono la mphira la zotanuka, kotero kuti pang'onopang'ono limabwezeretsa ubale wabwinobwino wa occlusal. Pambuyo pakuphulika kwa maxillary, ngati gawo la fracture likusunthira chammbuyo, nsonga ya mano imatha kuyikidwa pa maxillary dentition, ndi chipewa cha pulasitala chokhala ndi bulaketi yachitsulo zopangidwa pamutu.The zotanuka traction akhoza kupangidwa pakati pa mano arch splint ndi zitsulo bulaketi, kotero kuti maxillary fracture gawo akhoza kubwezeretsedwa patsogolo.Horizontal yokoka traction ingagwiritsidwenso ntchito pamene mphamvu yaikulu yokoka ikufunika.

3.Kuchepetsa kutseguka: Zizindikiro zochepetsera zotseguka ndi zazikulu.Kuchepetsa kotseguka kuyenera kuchitidwa pamene gawo la fracture likuchotsedwa kwa nthawi yaitali ndipo pali machiritso a fibrous kapena bony malalignment machiritso, ndipo kuchepetsa sikungatheke mwa kugwiritsira ntchito kapena kugwedeza. minofu ya fibrous yomwe imapangidwa mu machiritso a dislocation pakati pa mapeto osweka a fracture imachotsedwa kapena callus imachotsedwa, ndipo nsagwada zimachotsedwanso kuti zibwerere ku malo ake abwino. pakuchepetsa pamanja kapena kusakhazikika pambuyo pakuchepetsa.
