Txoj kev ligation thiab fixation ntawm lub puab tsaig me me yog tsim rau:
1. Ib leeg kab tawg ntawm lub cev mandible yam tsis muaj kev txav chaw.
2. Cov qog nqaij hlav ntawm lub cev mandibular lossis lub puab tsaig raug tshem tawm thiab cov pob txha grafted tam sim ntawd.
3. Kev pab kho kom zoo ntawm mandibular defects tom qab phom raug mob los ntawm pob txha grafting.
Kev txo qis thaum ntxov, kev kho thiab kev kho lub cev muaj zog yog peb lub hauv paus ntsiab lus rau kev kho mob ntawm ceg tawv fractures.Jaw pob txha pob txha kho txoj cai, muaj lawv qhov zoo sib xws thiab qhov sib txawv, lub puab tsaig sab sauv, vim nws cov leeg ntawm cov pob txha nto txuas nrog, ntxiv rau. lub tis ntawm sab hauv thiab sab nraud cov leeg, ntau dua rau kev qhia ntawm qee cov leeg tsis muaj zog, tsuav yog cov hniav tuaj yeem rov qab mus rau qhov qub kev sib raug zoo, txiav txim siab ntawm cov pob txha pob txha tau rov pib dua, tom qab ntawd xaiv cov txheej txheem ruaj khov ntawm pob txha taub hau.Thiab. mandible fracture vim yog lub zog masticatory cov leeg rub tuaj yeem ua rau pom tseeb qhov tsis sib xws, cov txheej txheem ntawm lub puab tsaig ruaj khov yuav tsum ruaj khov dua, tib lub sijhawm coj mus rau hauv tus account lub temporomandibular sib koom ntawm kev ua haujlwm thaum ntxov, kev ua haujlwm tsis muaj zog thiab tsis mob tuaj yeem txhawb nqa cov ntshav ntawm lub cev. pob txha thiab cov nqaij mos, cov kua dej synovial txhawb nqa cov khoom noj khoom haus pob txha pob txha, ua ke nrog ib feem ntawm qhov hnyav, tiv thaiv cov leeg nqaij atrophy, sib koom ua ke, thiab lwm yam., yog li ntawd, kev kho mob ntawm mandibular fracture cov lus qhia, aspires rau peb lub hauv paus ntsiab lus.
Restoring occlusion yog lub hom phiaj ntawm kev kho mob.Lub puab tsaig pob txha yog txawv ntawm qhov ntev ntawm cov hlab ntsha tawg, nws qhov tshwj xeeb tseem ceeb, uas yog, muaj kab mob ntawm lub puab tsaig ntawm lub puab tsaig, thiab tsim kom muaj kev sib raug zoo ntawm cov leeg sab sauv thiab qis qis, tswj kev ua haujlwm masticatory. Txawm hais tias txoj kev sib raug zoo ntawm cov hniav sab sauv thiab sab qis tuaj yeem rov qab los yog ib qho tseem ceeb tshaj plaws los ntsuas kev kho mob ntawm lub puab tsaig tawg.Cov hniav ntawm cov pob txha ntu feem ntau yog siv los ua kev txhawb nqa lossis thauj tog rau nkoj kom txo thiab kho los ntawm ligating arch. splints los yog lwm yam intraoral splints.Yog hais tias tsis yog phom raug mob, nws raug nquahu kom cov hniav ntawm txoj kab tawg yuav tsum tau khaws cia kom deb li deb tau.Yog tias cov hauv paus hniav tawg, cov hniav yog xoob heev, cov kab tawg raug cuam tshuam. los ntawm qhov thib peb mandibular molar los yog cov hniav yog embedded, cov hniav yuav tsum tau muab tshem tawm.Rau lub puab tsaig phom raug mob, ntau cherish lub alveolar txheej txheem ntawm cov hniav seem, yuav tsum tau rov qab thiab khaws cia los ntawm txhua txhua txoj kev ua tau, lub crown yog tawg tab sis muaj. lub hauv paus muaj zog, tshwj xeeb tshaj yog tom qab cov pob txha tawg ntawm cov hauv paus muaj zog, tuaj yeem siv rau kev kho cov kwj dej hauv paus, tab sis kuj muaj txiaj ntsig zoo rau kev ua tus ntsia thawv tom qab los yog npog lub fixation ntawm cov brackets.
Txog li 50-70% ntawm cov neeg uas muaj sia nyob ntawm kev sib tsoo tsheb raug mob ntawm lub ntsej muag.Hauv cov teb chaws tsim kho feem ntau, kev tsim txom los ntawm lwm tus neeg tau hloov tsheb sib tsoo yog qhov ua rau muaj kev raug mob maxillofacial;Nyob rau hauv cov ntaub ntawv ntawm kev tsim lub teb chaws kev sib tsoo tsheb tseem yog qhov tseem ceeb.Seatbelt thiab airbag tau siv los txo qhov tshwm sim ntawm maxillofacial trauma, tab sis tawg ntawm mandible, uas yog lub puab tsaig, tsis txo qis los ntawm cov kev tiv thaiv no.Kev siv cov kaus mom maus taus tuaj yeem txo qhov kev raug mob maxillofacial zoo.
Maxillofacial fractures yog faib nyob rau hauv ib tug ncaj ncaj nkhaus raws lub hnub nyoog, nrog ib tug ncov tshwm sim ntawm lub hnub nyoog 20 thiab 40, thiab cov me nyuam hnub nyoog qis dua 12 xyoo tsuas yog 5-10% ntawm tag nrho cov pob txha maxillofacial.Feem ntau maxillofacial trauma nyob rau hauv cov me nyuam muaj lacerations thiab cov nqaij mos raug mob.Muaj qhov qis dua ntawm cov pob txha cortical rau cov pob txha tshem tawm hauv cov menyuam yaus lub ntsej muag, cov pob txha tsim tsis zoo ua rau cov pob txha muaj zog, thiab cov ntaub npog rog muab kev tiv thaiv rau cov pob txha ntawm lub ntsej muag.
Kev raug mob taub hau thiab hlwb feem ntau cuam tshuam nrog maxillofacial trauma, tshwj xeeb tshaj yog ntawm lub ntsej muag sab sauv;mob hlwb tshwm sim nyob rau hauv 15-48% ntawm cov neeg uas muaj maxillofacial trauma.Coexisting raug mob tuaj yeem cuam tshuam kev kho mob ntawm lub ntsej muag;Piv txwv li lawv yuav tshwm sim thiab yuav tsum tau kho ua ntej raug mob ntawm lub ntsej muag.Cov neeg uas muaj kev raug mob saum toj no ntawm cov pob txha caj dab yog suav tias yog qhov muaj feem pheej hmoo rau kev raug mob ntawm ncauj tsev menyuam (kev raug mob ntawm tus txha caj qaum) thiab yuav tsum tau ceev faj tshwj xeeb kom tsis txhob txav ntawm tus txha caj qaum, uas tuaj yeem ua rau tus txha caj qaum.
