orthognathic 0.8 isahani ya genioplasti

Genioplasty ikubiyemo kubagwa gutandukanye kugirango ikosore iterambere ryinshi ryurwasaya, dysplasia, hamwe no gutandukana kwurwasaya, bikubiyemo imbere ninyuma, hejuru no hepfo, hamwe nibumoso hamwe niburyo butatu bwerekezo butatu bwurwasaya. hari itandukaniro rigaragara mubarwayi. Ingaruka nziza ya chin plasty nugushikira guhuza nibice byose bya craniofacial. Kubwibyo, ibikorwa bigomba gutegurwa ukurikije ubwoko bwa buri muntu.

Ibyerekana
