颏前徙成形术矫正轻中度小颌畸形10例体会

目的通过手术改善轻中度颏部发育不足及矫治颏偏斜不对称畸形,改善面下部鼻唇颏正侧面的综合形态.方法对颏部发育不足或颏部偏斜不对称患者共10例进行颏前徙成形术,患者均不伴有明显咬合紊乱及颞下颌关节紊乱症状,其中颏部垂直向发育不足者2例,前后向发育不足者3例,前后及垂直向兼有者3例,颏部偏斜者2例,其中2例为硅胶假体隆颏术后外形不满意,术前本身就为颏部前后向发育欠佳.手术纠正了患者颏部垂直向及前后向的外形,并改善了鼻唇颏的正侧面综合形态.结果所有患者术后随访3～6个月,均恢复良好,术后面下部鼻唇颏综合外形满意,无不良反应.结论颏前徙成形术对于单纯的轻中度颏发育不足及颏部偏斜不对称患者的下颌部外形有明显的改善,术后面下部鼻唇颏形态效果良好,避免了硅胶假体隆颏术后继发局部骨质吸收、假体移位等弊端.
