maxillofacial trauma micro X phaj

Kev raug mob ntawm qhov ncauj thiab maxillofacial feem ntau yog tshwm sim los ntawm kev raug mob ntawm kev ua haujlwm, kev raug mob kis las, kev sib tsoo thiab kev raug mob hauv lub neej.Cov ntshav ncig ntawm maxillofacial yog nplua nuj, txuas nrog lub paj hlwb thiab lub caj dab, thiab nws yog qhov pib ntawm txoj hlab pa thiab plab hnyuv.Muaj ntau cov pob txha maxillofacial thiab kab noj hniav.Muaj cov hniav txuas rau cov pob txha maxillofacial, thiab tus nplaig muaj nyob rau hauv lub qhov ncauj.Lub ntsej muag muaj cov leeg ntawm lub ntsej muag thiab cov hlab ntsha ntawm lub ntsej muag; Lub temporomandibular sib koom tes thiab cov qog qaub ncaug; Lawv ua haujlwm ntawm kev hais lus, hais lus, zom, nqos thiab ua pa.

Kev kho cov pob txha maxillofacial tom qab txo qis yog ib qho tseem ceeb hauv kev kho mob. Feem ntau siv cov kev kho mob xws li ib lub puab tsaig arch splint fixation, interjaw fixation, interjaw ligation fixation, miniplate los yog microplate fixation, cranial thiab puab tsaig fixation, thiab lwm yam kev xws li perimaxillary fixation thiab compression. phaj fixation.

1. Txoj kev kho lub cev ntawm ib lub puab tsaig kho hniav arch: nws yog siv 2 hli txoj kab uas hla txhuas hlau los yog tiav cov khoom nrog nuv hniav arch splint, raws li cov duab ntawm cov hniav arch, thiab ces siv zoo hlau ligation hlau los ntawm cov hniav chaw, lub splint yog ligated rau ntawm ib feem lossis tag nrho cov hniav ntawm ob sab ntawm txoj kab tawg, txhawm rau txhim kho cov pob txha tawg.Qhov no yog qhov tsim nyog rau cov pob txha tsis muaj kev txav txav, xws li linear midline fracture ntawm maxillochin thiab localized alveolar fracture. .

2. Intermaxillary fixation: cov txheej txheem yog muab ib tug hooked hniav arch splint rau sab sauv thiab sab cov hniav, thiab ces siv ib tug me me roj hmab band rau intermaxillary fixation, thiaj li hais tias lub puab tsaig nyob rau hauv txoj hauj lwm ntawm ib txwm occlusal kev sib raug zoo. yog txhim khu kev qha, haum rau ntau yam mandibular fractures, qhov zoo dua yog tias lub puab tsaig tuaj yeem kho tau zoo, yog qhov zoo rau kev rov ua haujlwm, qhov tsis zoo yog tias cov neeg raug mob tsis tuaj yeem qhib qhov ncauj noj, kuj tsis yooj yim. kom tswj qhov ncauj huv si, yuav tsum ntxiv dag zog rau kev saib xyuas neeg mob.

3. Interosseous ligation thiab fixation: nyob rau hauv cov ntaub ntawv ntawm kev phais qhib txo, ob qhov kawg ntawm cov pob txha tawg tuaj yeem raug drilled thiab tom qab ntawd ligated thiab tsau los ntawm cov hlau tsis muaj steel hlau.Qhov no kuj yog ib txoj kev txhim khu kev qha.Jawbone puas thiab toothless lub puab tsaig. Kev tawg ntawm cov menyuam yaus kuj tuaj yeem kho los ntawm txoj kev no.

4. Cov phaj me me lossis micro phaj fixation: nyob rau hauv lub hauv paus ntawm phau ntawv qhib txo, ib lub phaj me me los yog micro phaj ntawm qhov tsim nyog ntev thiab cov duab yog muab tso rau thoob plaws pob txha nto ntawm ob qhov kawg ntawm lub pob txha tawg, thiab ib tug tshwj xeeb ntsia hlau yog siv rau nkag mus rau hauv cov pob txha cortex los txhim kho lub phaj, thiaj li ua tiav lub hom phiaj ntawm kev txhim kho ntawm cov pob txha tawg. Cov phaj me feem ntau yog siv rau cov mandible, thaum cov phaj micro yog siv rau maxilla.

5. Cranial thiab maxillofacial fixation txoj kev: maxillary transverse puas, tsis tsuas yog cia siab rau lub mandible fixation, siv tau lub pob txha taub hau rau fixation, txwv tsis pub lub nruab nrab lub ntsej muag yog prone mus rau elongated deformation.Cov txheej txheem ntawm fixation yog thawj qhov chaw ntawm lub arch splint. Nyob rau ntawm cov hniav maxillary, ces khi ib kawg ntawm lub arch splint nyob rau hauv lub posterior hniav cheeb tsam nrog stainless hlau hlau, thiab lwm yam kawg ntawm lub arch splint los ntawm lub qhov ncauj kab noj hniav los ntawm cov ntaub so ntswg ntawm lub zygomaticocheek, thiab dai ntawm kev txhawb nqa ntawm lub qhov ncauj kab noj hniav. plaster cap.Tam sim no, intermaxillary fixation tau ntxiv.

Lub sij hawm ntawm lub puab tsaig kho lub puab tsaig tuaj yeem txiav txim siab raws li tus neeg mob qhov kev raug mob, hnub nyoog thiab kev mob tshwm sim.Nws feem ntau yog 3 ~ 4 lub lis piam rau maxilla thiab 4 ~ 8 lub lis piam rau mandible.Cov txheej txheem dynamic thiab zoo li qub tuaj yeem siv los txo lub sijhawm. interjaw fixation.Txoj kev yog tias tom qab 2 mus rau 3 lub lis piam ntawm immobilization, lub nplhaib roj hmab raug tshem tawm thaum pub mis thiab kev txav kom zoo raug tso cai.Tom qab siv cov phaj me me los yog micro phaj rau kev txhim kho sab hauv, kev ua haujlwm zoo tuaj yeem nqa tawm hauv ua ntej los txhawb kev puas tsuaj.
