I-orthognathic 0.8 ipuleti ye-genioplasty

I-Genioplasty ihlanganisa ukuhlinzwa okunhlobonhlobo ukuze kulungiswe ukukhula ngokweqile komhlathi, i-dysplasia, nokuchezuka komhlathi, okubandakanya ingaphambili nengemuva, elingaphezulu nangaphansi, nesobunxele kanye nesokudla lokungajwayelekile kwesilevu. i-bone flap ye-mandibular chin futhi iyindlela yokuhlinzwa engcono kakhulu yokulungisa ukungavamile okuhlukahlukene kwesilevu.Ngenxa yomehluko omkhulu ngamunye esilevini, ngisho nokukhubazeka okufanayo, kunomehluko osobala phakathi kweziguli.Umphumela omuhle kakhulu we-chin plasty ukufeza ukuxhumana nazo zonke izingxenye ze-craniofacial.Ngakho-ke, ukusebenza kufanele kuklanywe ngokuya ngohlobo lobuso bomuntu ngamunye.

Izinkomba

1. Nciphisa ububanzi bangaphambili nangemuva besilevu bese ulungisa ukuphuma phambili kwesilevu.

2. Khulisa ububanzi bangaphambili nangemuva besilevu futhi ulungise ukukhubazeka kokuhlehla kwesilevu.

3. Khulisa ukuphakama kwesilevu futhi ulungise ukuntula ohlangothini oluqondile lwesilevu.

4. Nciphisa ukuphakama kwesilevu futhi ulungise isiqondiso esiqondile sesilevu.

5. Khulisa ububanzi besilevu futhi ulungise ukuntula kobubanzi besokunxele nesokudla kwesilevu.

6. Zungezisa isilevu ukuze ulungise ukuchezuka kwesilevu nokunye ukukhubazeka kwe-asymmetrical.

7. lezi zimo eziningana ezingenhla zingaba khona esigulini esisodwa, isikhathi sokuklama.Izici ezingavamile ngesikhathi esisodwa kufanele zicatshangelwe.Lokhu kusebenza kuvame ukuhlanganiswa nokunye ukuhlinzwa kwe-orthognathic ukulungisa ukukhubazeka okuyinkimbinkimbi kwamazinyo kanye ne-maxillofacial.

Izinyathelo zokuhlinza

I-Anteroposterior mental underdevelopment iwukukhubazeka kwengqondo okuvame kakhulu futhi kwasekuqaleni abantu abakunaka.Izimo ezinzima zokuhlehla kwesilevu, ukubukeka kwayo eceleni kuwuqhwaku, kuthinta kakhulu ukubukeka kobuhle.I-Advancement genioplasty iyindlela evame ukusetshenziswa kakhulu yokulungisa isilevu sangemuva. ukukhubazeka.Umgomo wendlela ye-intraoral ukusika ithambo elihlangene maphakathi ne-mandible ezingeni lephoyinti lempande lamazinyo angaphansi angaphambili kanye ne-lateral submental foramina, ukugcina ubuqotho be-pedicle yokuhlinzeka ngegazi ye-lingual soft. izicubu kanye nemisipha ngemva kokusikwa, hambisa ithambo phambili uye endaweni entsha bese ulilungisa kabusha nge-mandible.Ngenxa yokuthi izicubu ezithambile ezixhunywe engxenyeni ye-labial kanye ne-buccal ye-block ye-chin bone block nayo yaqhubekela phambili, ukukhubazeka kokuhlehla kwe-chin kwalungiswa. .

I-osteotomy line ngokuvamile itholakala ngo-0.5 cm ngaphansi kwephuzu lempande ukuze kuvinjwe ichopho lezinyo ukuthi lingonakali futhi kuqinisekiswe ukuthi inzwa nokunikezwa kwegazi ezinyoni. kuya ezicutshini ezithambile ezifana ne-lingual muscle pedicle, okuholela e-hematoma nokuvuvukala kwephansi lomlomo ngemva kokuhlinzwa, futhi ukusunduza ulimi emuva futhi kuthinte ukuphefumula.I-pedicle yezicubu ezithambile zemisipha engaphansi komugqa we-osteotomy kufanele ivikelwe, ikakhulukazi isifunda esiphakathi kwengqondo, okuhlanganisa nesisu sangaphambili somsipha we-digastric kanye nephuzu lokunamathisela lomsipha we-geniohyoid emaphethelweni angemuva kwethambo elingaphansi, ukuze kuqinisekiswe ukutholakala kwegazi ku-osteotomy.Ukulungiswa kwangaphakathi kwenziwa ngepuleti le-titanium noma isikulufu.Gwema ukulimala esihlokweni sezinyo.I-layered suture.I-mentoplasty iyagobeka futhi ingenziwa ngezindlela eziningi: i-osteotomy evundlile kanye nokufuduka phambili;I-osteotomy enezingqimba kanye nokwelulwa kwangaphambili;Isinyathelo esiphindwe kabili i-osteotomy evundlile kanye ne-osteotomy yangaphambili;I-osteotomy enezingqimba, ukufinyeza nokubuyisela emuva;I-osteotomy evundlile kanye nokufinyeza okungaphambili;Ukuguqulwa okuvundlile;Ukunqunywa kwengxenye engunxantathu;Ukuguqulwa kwe-rotary okuvundlile;Ukunwetshwa kwengxenye yesilevu;Ukuvinjelwa kwesilevu.
