ipleyiti ye-orthognathic ye-0.8 ye-genioplasty

I-Genioplasty ibandakanya utyando olwahlukeneyo ukulungisa ukuphuhla okugqithisileyo komhlathi, i-dysplasia, kunye nokutenxa kwemihlathi, okubandakanya umphambili nasemva, phezulu nasezantsi, nasekhohlo nasekunene-ntathu-ntathu kwicala elingaqhelekanga le-chin. i-bone flap ye-mandibular chin ikwalolona tyando lulungileyo lokulungisa ukungaqhelekanga okwahlukeneyo kwesilevu.Ngenxa yomahluko omkhulu womntu ngamnye esilevini, nakwisiphene esifanayo, 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

I-Anteroposterior mental underdevelopment yeyona nto ixhaphakileyo kunye neyokuqala yokukhubazeka kwengqondo ukuba abantu banikele ingqalelo.Iimeko ezibukhali zokurhoxa kwesilevu, inkangeleko yayo esecaleni "yimbongolo" imilo, ichaphazela kakhulu inkangeleko yobuhle.I-genioplasty ye-Advancement yeyona nkqubo isetyenziswa kakhulu ukulungisa isilevu esingasemva. ukukhubazeka.Umgaqo wendlela ye-intraoral kukusika ithambo elidibeneyo kumbindi we-mandible kwinqanaba lengcambu yamazinyo angaphantsi angaphambili kunye ne-lateral submental foramina, gcina ingqibelelo ye-pedicle yonikezelo lwegazi ye-lingual soft. izicubu kunye nezihlunu emva kokunqunyulwa, hambisa ithambo phambili kwindawo entsha kwaye uyilungise kwakhona nge-mandible.Ngenxa yokuba i-tissue ethambileyo efakwe kwi-labial kunye ne-buccal yamacala e-chin bone block nayo yaqhubela phambili, ukukhubazeka kwe-chin retraction kwalungiswa. .

Umgca we-osteotomy uhlala u-0.5 cm ngaphantsi kwencam yengcambu ukukhusela incam yamazinyo ukuba yonakaliswe kwaye uqinisekise i-nerve kunye negazi kwizinyo. kwizicubu ezithambileyo ezifana ne-lingual muscle pedicle, okubangelwa i-hematoma kunye nokuvuvukala komgangatho womlomo emva kokusebenza, kunye nokubuyisela ulwimi emva kunye nokuchaphazela ukuphefumla. ummandla ophakathi kwengqondo, kubandakanywa isisu sangaphambili se-digastric muscle kunye nenqaku lokunamathisela kwi-muscle ye-geniohyoid kwi-posterior margin ye-submental bone, ukuqinisekisa ukunikezelwa kwegazi kwi-osteotomy.Ukulungiswa kwangaphakathi kwenziwa nge-titanium plate okanye isikrufu.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.
