I-orthognathic 0.8 ipuleti ye-genioplasty

I-Genioplasty ihlanganisa ukuhlinzwa okuhlukahlukene ukuze kulungiswe ukukhula ngokweqile komhlathi, i-dysplasia, nokuchezuka komhlathi, okubandakanya ingaphambili nangemuva, phezulu nangaphansi, nesobunxele nakwesokudla okunezinhlangothi ezintathu zesilevu okungavamile.I-mentoplasty esekelwe ku-muscle pedicle bone flap ye-mandibular chin futhi ilungisa umehluko omkhulu we-chinnor ngayinye ye-chinnor ngayinye. esilevini, ngisho nasekukhubazekeni 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 ukukhubazeka kwengqondo okuvame kakhulu futhi kwasekuqaleni abantu abakunaka.Izimo ezinzima zokuhlehla kwesilevu, ukubukeka kwayo kweceleni kungumumo "woqhwaku", kuthinta kakhulu ukubukeka kobuhle.I-Advancement genioplasty iyindlela evame ukusetshenziswa kakhulu yokulungisa ukukhubazeka kwe-posterior chin.Umgomo weleveli ye-mandible yempande ephakathi nendawo yokusika ithambo le-tip eliphakathi nendawo eliphakathi nendawo eliphakathi nendawo eliphakathi nendawo le-mandible eliphakathi nendawo eliphakathi nendawo lempande ye-mandible amazinyo aphansi angaphambili kanye ne-lateral submental foramina, gcina ubuqotho be-pedicle yokuhlinzeka ngegazi yezicubu ezithambile zolimi kanye nemisipha ngemva kokusikwa, hambisa ithambo phambili endaweni entsha bese ulilungisa kabusha nge-mandible.Ngenxa yokuthi izicubu ezithambile ezixhunywe ezinhlangothini ze-labial ne-buccal ze-chin bone block nazo zaqhubekela phambili, ukukhubazeka kokuhlehla kwe-chin kwalungiswa.

I-osteotomy line ivame ukutholakala ngo-0.5 cm ngaphansi kwephuzu lempande ukuze kuvinjwe ithiphu lezinyo ukuthi lingalimazi futhi kuqinisekiswe ukuthi inzwa kanye nokunikezwa kwegazi ezinyoni.Lapho i-lingual bone plate inqanyuliwe, ukuhlinzwa kufanele kube mnene futhi kunembile ukuze kugwenywe ukulimala kwezicubu ezithambile ezifana ne-lingual muscle pedicle, okuholela ku-hematoma nokuvuvukala kwesitezi somlomo ngemuva kokusebenza, futhi ukuphefumula kwemisipha kuthinta izicubu ezithambile ngemuva kokusebenza. umugqa we-osteotomy kufanele uvikelwe, ikakhulukazi esifundeni esiphakathi kwengqondo, kuhlanganise nesisu sangaphambili se-digastric muscle kanye nephuzu lokunamathisela le-geniohyoid muscle emaphethelweni angemuva kwethambo elingaphansi, ukuqinisekisa 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.
