摘　　要：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.Objective To correct mild and moderate micrognathia by surgical treatment,and improve the basifacial appearance of patients.Methods Advancement genioplasty was performed in 10 patients with insufficient development of mentum or asymmetric mentum,including 2 patients with insufficient vertical development of mentum,3 patients with insufficient anterior-posterior development of mentum,3 patients with insufficient vertical and anterior-posterior development of mentum,and 2 patients with mentum deflection.All patients had no obvious symptoms of occlusion disorder and disorders of temporomandibular joint.2 patients with anterior-posterior development of mentum once received genioplasty using silicome prosthesis before advancement genioplasty,but they were not satisfied with the basifacial appearance.The advancement genioplasty corrected the vertical and anterior-posterior appearance of mentum and improved the basifacial frontal and lateral appearance.Results All patients were followed up for 3～6 months,and had good recovery.The comprehensive basifacial appearance of patients was satisfactory and no adverse reactions were found.Conclusion Advancement genioplasty can improve significantly the basifacial appearance of patients with mild and moderate insufficient development of mentum and mentum deflection,avoid the disadvantages such as local bone absorption and prosthesis displacement caused by genioplasty using silicome prosthesis,and the basifacial appearance after genioplasty is satisfactory
