ipleyiti ye-orthognathic ye-0.8 ye-genioplasty

I-Genioplasty ibandakanya utyando olwahlukeneyo ukulungisa uphuhliso olugqithisileyo lomhlathi, i-dysplasia, kunye nokutenxa kwemihlathi, okubandakanya umphambili nasemva, phezulu nasezantsi, nasekhohlo nasekunene-ntathu-ntathu kwicala elingaqhelekanga le-chin. kwi-chin, nakwi-deformity efanayo, kukho umahluko ocacileyo phakathi kwezigulane. Isiphumo esihle kakhulu se-chin plasty kukufezekisa ukulungelelaniswa nazo zonke iindawo ze-craniofacial. Ngoko ke, umsebenzi kufuneka uyilwe ngokohlobo lomntu ngamnye.

Iimpawu

1. Yenza mfutshane i-diameter yangaphambili nangemuva ye-chin kwaye ulungise i-protrudence yangaphambili ye-chin.

2. Yandisa i-diameter yangaphambili nangemuva ye-chin kwaye ulungise ukukhubazeka kwe-chin retraction.

3. Ukwandisa ukuphakama kwe-chin kwaye ulungise ukusilela kwicala elithe nkqo le-chin.

4. Nciphisa ukuphakama kwesilevu kwaye ulungise ulwalathiso oluthe nkqo lwesilevu.

5. Ukwandisa ububanzi be-chin kwaye ulungise ukusilela kwe-diameter ekhohlo nekunene ye-chin.

6. Jikelezisa isilevu ukulungisa ukuphambuka kwesilevu kunye nokunye ukukhubazeka kwe-asymmetrical.

7. Ezi meko zininzi zingentla zinokubakho kwisigulane esifanayo, ixesha loyilo.Izinto ezingaqhelekanga ezingaqhelekanga kufuneka ziqwalaselwe.Lo msebenzi udla ngokudibaniswa nolunye utyando lwe-orthognathic ukulungisa ukukhubazeka kwamazinyo kunye ne-maxillofacial deformities.

Amanyathelo otyando

Anteroposterior ingqondo underdevelopment yeyona nto ixhaphakileyo kwaye kwakuqala ukukhubazeka kwengqondo ukuba abantu ingqalelo.Amatyala kakhulu ukurhoxa kwesilevu, inkangeleko yayo ecaleni "umlomo" imilo, kuchaphazela ngokunzulu inkangeleko ubuhle.Advancement genioplasty yeyona nkqubo isetyenziswa ngokuqhelekileyo ukulungisa isilevu yangasemva. amazinyo angaphantsi angaphambili kunye ne-lateral submental foramina, gcina ingqibelelo ye-pedicle yonikezelo lwegazi ye-lingual soft tissue kunye ne-muscle emva kwe-incision, ukuhambisa ithambo phambili kwindawo entsha kwaye uyilungise kwakhona kunye ne-mandible.Ngenxa yokuba i-tissue ethambileyo eqhotyoshelwe kwi-labial kunye ne-buccal yamacala e-chin bone ibhloko nayo yaqhubela phambili, ukukhubazeka kwe-chin retraction kwalungiswa.

Umgca we-osteotomy uhlala u-0.5 cm ngaphantsi kweengcambu zengcambu ukukhusela incam yezinyo ukuba ingonakaliswe kwaye uqinisekise ukuba i-nerve kunye nokunikezelwa kwegazi kwizinyo.Xa i-lingual bone plate inqunyulwe, umsebenzi kufuneka ube mnene kwaye uchanekileyo ukuze ugweme umonakalo kwizicubu ezithambileyo ezifana ne-lingual muscle pedicle, okubangelwa i-hematoma kunye nokuvuvukala komgangatho womlomo womlomo emva kokusebenza, kunye nokuphefumula kolwimi oluthambileyo kwi-pedicle emva kokusebenza. umgca we-osteotomy kufuneka ukhuselwe, ngokukodwa kwingingqi ephakathi kwengqondo, kubandakanywa isisu sangaphambili se-digastric muscle kunye ne-attachment point of the geniohyoid muscle at the posterior margin of the submental bone, ukuqinisekisa ukunikezelwa kwegazi kwi-osteotomy. Ukulungiswa kwangaphakathi kwenziwa nge-titanium plate okanye i-screw. Gwema umonakalo kwincam yezinyo.I-layered suture.I-mentoplasty iguquguqukayo kwaye inokwenziwa ngeendlela ezininzi: i-osteotomy ethe tyaba kunye nokufuduswa phambili; I-osteotomy ethe tyaba kunye nokwandiswa kwangaphambili; Inyathelo eliphindwe kabini i-osteotomy ethe tyaba kunye ne-osteotomy yangaphambili; I-osteotomy ethe tye, ukunciphisa kunye nokubuyisela emva; I-osteotomy ethe tyaba kunye nokunciphisa kwangaphambili; Ukunqunyulwa kwecandelo elingunxantathu; Ukutshintshwa okujikelezayo okuthe tye; Ukwandiswa kwecandelo le-chin; Ukunqanda isilevu.
