orthognathic 0.8 isahani ya genioplasti

Genioplasty ikubiyemo kubagwa gutandukanye kugirango ikosore iterambere ridakabije ry'urwasaya, dysplasia, no gutandukana kw'urwasaya, bikubiyemo imbere n'inyuma, hejuru no hepfo, n'ibumoso n'iburyo icyerekezo cy'ibice bitatu-bidasanzwe bidasanzwe by'urwasaya. Mentoplastique ishingiye ku mitsi y'imitsi. igufwa ryamagufwa ya mandibular chin nubundi buryo bwiza bwo kubaga gukosora ibintu bitandukanye bidasanzwe byinini. Bitewe nuko itandukaniro rinini ryabantu ku giti, ndetse no mubumuga bumwe, hariho itandukaniro rigaragara mubarwayi.Ingaruka nziza ya chin plasty nugushikira guhuza nibice byose bya craniofacial.Kubwibyo, ibikorwa bigomba gutegurwa ukurikije ubwoko bwa buri muntu.

Ibyerekana

1. Gabanya diameter imbere ninyuma yumusaya hanyuma ukosore imbere yimbere.

2. Ongera diameter imbere ninyuma yumusaya hanyuma ukosore ubumuga bwo gukuramo urusaku.

3. Ongera uburebure bwikinono kandi ukosore ibura mubyerekezo bihagaritse byinini.

4. Kugabanya uburebure bwikinono kandi ukosore icyerekezo cyerekezo cyumusaya.

5. Ongera ubugari bwurwasaya kandi ukosore ibura rya diameter yibumoso na iburyo.

6. Kuzunguruka umunwa kugirango ukosore gutandukana kwinini hamwe nubundi buryo budasanzwe.

7. ibintu byinshi byavuzwe haruguru birashobora kubaho mumurwayi umwe, mugihe cyo gushushanya.Ibintu bidasanzwe icyarimwe bigomba gutekerezwa. Iki gikorwa gikunze guhuzwa nubundi buryo bwo kubaga orthognathique kubwo gukosora amenyo akomeye hamwe na maxillofacial.

Intambwe yo kubaga intambwe

Iterambere ryimitekerereze ya Anteroposterior nuburyo bukunze kugaragara kandi bwambere bwo mumitekerereze abantu bitondera. Ibibazo bikabije byo gukuramo urusaku, isura yacyo ni "beak", bigira ingaruka zikomeye kumiterere yubwiza.Avvancement genioplasty nuburyo bukoreshwa cyane mugukosora urwasaya rwinyuma ubumuga. Ihame ryuburyo bwimbere ni ugukata igufwa rifatanije hagati ya mandible kurwego rwumutwe wumuzi w amenyo yimbere yimbere hamwe na foramina yinyuma, komeza ubudakemwa bwamaraso atanga pedicle yoroheje yururimi rworoshye ingirangingo n'imitsi nyuma yo gutemwa, shyira igufwa imbere mumwanya mushya hanyuma wongere ukosore hamwe na manda.Kubera ko tissue yoroshye yometse kumpande ya labial na buccal kumpande yamagufwa ya chin nayo yagiye imbere, ubumuga bwo gukuramo urusaku bwarakosowe. .

Umurongo wa osteotomy mubusanzwe uba uri kuri cm 0,5 munsi yumutwe wumuzi kugirango wirinde ko iryinyo ryangirika kandi ryizere ko imitsi n amaraso bitangwa kumenyo. ku ngingo zoroshye nka pedicle imitsi y'ururimi, bikaviramo hematoma no kubyimba hasi kumunwa nyuma yo kubagwa, no gusubiza ururimi inyuma bikagira ingaruka no guhumeka.Pedicle yoroheje yimitsi yimitsi iri munsi yumurongo wa osteotomy igomba kurindwa, cyane cyane muri agace ko hagati, harimo ninda yimbere yimitsi ya digastrica hamwe nu mugereka wimitsi ya geniohyoid kumpera yinyuma yamagufwa ya submental, kugirango amaraso atange osteotomy.Gukosora imbere bikorwa hamwe na plaque ya titanium cyangwa screw.Irinde kwangirika kw'isonga ry'iryinyo. Suture yataye umurongo. Mentoplasti iroroshye kandi irashobora gukorwa muburyo butandukanye: osteotomy ya horizontal no kwimura imbere;Horizontal osteotomy no kurambura imbere;Intambwe ebyiri zitambitse osteotomy na osteotomy y'imbere;Horizontal osteotomy, kugabanya no gusubira inyuma;Horizontal osteotomy no kugabanya imbere; Guhinduranya gutambitse;Igice cya mpandeshatu;Guhinduranya gutambitse;Kwagura igice cy'urwasaya;Kwinuba.
