locking reconstruction anatomical 120 ° phaj (ib lub qhov xaiv ob hom ntsia hlau)

Raws li ib qho tseem ceeb ntawm lub ntsej muag lub cev kom muaj kev zoo nkauj, cov duab ntawm lub mandible plays lub luag haujlwm tseem ceeb hauv kev zoo nkauj ntawm lub ntsej muag.Muaj ntau yam xws li kev raug mob, kab mob, qog resection thiab lwm yam tuaj yeem ua rau qhov tsis xws luag.Qhov tsis xws luag ntawm mandible tsis tsuas yog cuam tshuam rau tus neeg mob lub ntsej muag, tab sis kuj ua rau muaj qhov txawv txav hauv kev zom, nqos, hais lus thiab lwm yam haujlwm.Qhov zoo tshaj plaws mandibular reconstruction yuav tsum tsis tsuas yog ua kom tiav thiab kev ncaj ncees ntawm cov pob txha mandibular thiab kho lub ntsej muag, tab sis kuj. muab cov xwm txheej yooj yim rau kev rov ua haujlwm tom qab lub cev muaj zog xws li zom, nqos thiab hais lus.

Qhov ua rau mandible defect

Kev kho mob qog: ameloblastoma, myxoma, carcinomas, sarcomas.

Avulsive traumatic raug mob: feem ntau tshwm sim los ntawm kev raug mob siab ceev xws li phom, muaj xwm txheej, thiab qee zaus tsheb sib tsoo.

Inflammatory los yog kis mob.

Lub hom phiaj ntawm Kev Txhim Kho

1. Rov qab kho qhov qub qub ntawm qhov qis thib peb ntawm lub ntsej muag thiab lub mandible

2. Khaws qhov txuas ntxiv ntawm lub mandible thiab rov qab kho qhov chaw sib raug zoo ntawm cov mandible thiab cov ntaub so ntswg ib puag ncig.

3. Rov qab zoo zom, nqos, thiab hais lus ua haujlwm

4. Khaws txoj hlab cua kom txaus

Muaj plaub hom microreconstruction ntawm mandibular defects.Tauma thiab qog resection ntawm lub mandible tej zaum yuav cuam tshuam rau cov tsos thiab ua rau lub functional deficits xws li malocclusion vim unilateral nqaij raug mob.In thiaj li kho cov tsos mob thiab reconstruct lub muaj nuj nqi, ntau txoj kev phais muaj. tau tsim, thiab qhov nyuaj ntawm kev tsim kho kom zoo ntawm mandible lus dag nyob rau hauv kev xaiv ntawm txoj kev zoo tshaj plaws.Vim tias qhov nyuaj ntawm mandibular defect, ib txheej ntawm cov txheej txheem yooj yim, cov tswv yim thiab feem ntau lees txais kev faib tawm thiab cov kev kho mob tseem yog dawb huv.Schultz et al.ua qauv qhia kev yooj yim ntawm kev faib tawm tshiab thiab cov txheej txheem sib txuas rau kev tsim kho thiab kho cov mandible los ntawm kev xyaum, uas tau luam tawm nyob rau hauv phau ntawv xov xwm tshiab ntawm PRS.Qhov kev faib tawm no tsom rau kev ncaj ncees ntawm cov hlab ntsha hauv cheeb tsam tus neeg tau txais kev pab, nrog rau kev saib xyuas kom raug kho qhov nyuaj mandibular. Cov kev tsis xws luag los ntawm microsurgical txhais tau tias.Cov txheej txheem yog thawj zaug muab faib ua plaub hom raws li qhov nyuaj ntawm kev phais kho dua tshiab.Qhov nruab nrab ntawm lub mandible yog ib thaj tsam.Hom 1 muaj qhov tsis xws luag uas tsis koom nrog lub kaum sab xis ntawm lub mandibular, hom 2 muaj qhov tsis xws luag nrog lub ipsilateral mandibular Angle, hom 3 muaj qhov tsis xws luag ntawm ob sab ntawm lub kaum sab xis ntawm lub mandibular, thiab hom 4 muaj qhov tsis xws luag ntawm ob sab ntawm lub unilateral. los yog ob sab mandibular Angle.Txhua hom tau muab faib ua hom A (muaj feem xyuam) thiab hom B (tsis siv tau) raws li seb cov hlab ntsha ipsilateral puas haum rau anastomosis.Hom B yuav tsum tau anastomosis ntawm contralateral cervical hlab ntsha.Rau hom 2 mob, nws yog ib qhov tsim nyog los qhia seb cov txheej txheem condylar puas muaj feem cuam tshuam los txiav txim siab seb cov khoom siv graft siv li cas: Kev koom tes nrog condylar Unilateral yog 2AC / BC, thiab tsis muaj kev koom tes nrog condylar yog 2A. /B.Raws li cov kev faib tawm saum toj no thiab txiav txim siab ntawm daim tawv nqaij tsis xws luag, qhov ntev ntawm cov mandibular defect, xav tau cov hniav cuav, thiab lwm yam xwm txheej tshwj xeeb, tus kws phais ntxiv txiav txim siab txog hom pob txha dawb uas yuav siv tau.

Preformed Reconstruction Phaj yog npaj rau siv nyob rau hauv qhov ncauj thiab maxillofacial phais, raug mob thiab reconstructive phais.Qhov no suav nrog kev tsim kho thawj zaug mandibular, comminuted fractures thiab ib ntus txuas txuas rau ncua ncua kev tsim kho theem nrab, suav nrog cov pob txha ntawm edentulous thiab / lossis atrophic mandibles, nrog rau cov pob txha tsis ruaj khov.Cov txiaj ntsig ntawm tus neeg mob - los ntawm kev nrhiav kom ua tiav cov txiaj ntsig zoo nkauj txaus siab thiab txo lub sijhawm ua haujlwm.Patient Specific Plates for Mandible tshem tawm cov kev ntxhov siab ntawm cov khoom siv khoov los ntawm cov ntawv khoov.
