Anteroposterior mental underdevelopment ndiyo yakajairika uye yepakutanga mental deformity iyo vanhu vanoteerera kune.Severe chin retraction cases, iyo lateral kutaridzika ndeye "beak" chimiro, inokanganisa zvakanyanya kuonekwa kwerunako.Advancement genioplasty ndiyo inonyanya kushandiswa nzira yekugadzirisa posterior chin deformity.Nheyo yemukati mandip midzi yejointi yekubatana kwemukati wemukati wemukati we mandip nzira yekucheka pfupa remukati wemukati weti yepakati pemandi. mazino ezasi anterior uye lateral submental foramina, kuchengetedza kutendeseka kweropa rekupa pedicle ye lingual soft tissue uye musuru mushure mekucheka, fambisa pfupa mberi kune imwe nzvimbo uye uigadzirise zvakare nemandible.Nekuda kwekuti zvinyoro zvinyoro zvakasungirirwa kune labial uye buccal mativi echirebvu bone chivharo chakaenderera mberi, chirebvu chekudzorera chirebvu chakagadziriswa.

osteotomy line inowanzowanikwa 0.5 cm pasi pemudzi weti kuti udzivise zino rezino kuti rirege kukuvadzwa uye kuve nechokwadi chetsinga neropa kune zino.Kana lingual bone plate inogurwa, kushanda kunofanira kuva kwakadzikama uye kwakarurama kuti kurege kukuvadza kune zvinyoro zvinyoro zvakadai se lingual muscle pedicle, zvichiita kuti hematoma uye kuzvimba kwemuromo wepasi pasi mushure mekushanda, uye kuputika kwepasi pemuromo wepasi pevhu kunokanganisa rurimi rwemuscular pedicle shure kwekushanda, uye kufema kwepamuviri kunobata musuru. mutsara we osteotomy unofanirwa kuchengetedzwa, kunyanya munharaunda yepakati-yepfungwa, kusanganisira anterior belly of the digastric muscle uye nzvimbo yekunamatira ye geniohyoid muscle pamucheto wekupedzisira we submental bone, kuve nechokwadi chekupa ropa kune osteotomy. Kugadziriswa kwemukati kunoitwa netitanium plate kana screw. Dzivisa kukuvadzwa kumuromo wezino.Layered suture.Mentoplasty inoshanduka uye inogona kuitwa nenzira dzakawanda: horizontal osteotomy uye mberi displacement; Horizontal osteotomy uye anterior kureba; Kaviri nhanho yakatwasuka osteotomy uye anterior osteotomy; Horizontal osteotomy, kupfupisa uye retrograde; Horizontal osteotomy uye anterior kupfupisa;Horizontal transposition; Triangular segment amputation; Horizontal rotary transposition; Kuwedzera kwechikamu chechirebvu; Chin constriction.
