To evaluate treatment of vertical microgenia in patients with chin deformities.
Twenty-one patients were included in this retrospective review. The 3 authors performed a lengthening genioplasty with or without interpositional grafting on each patient in either an academic or a private practice setting.
Subjective analysis suggests a substantial improvement of lower face aesthetics in all patients. The degree of subjective change depended on the type of deformity, whether there was vertical microgenia alone or in combination with a sagittal (horizontal) deficiency, and the morphologic characteristics of the labiomental sulcus. There were no significant complications.
Vertical lengthening of the chin should be considered in patients with the combination of a vertically short lower facial height, deepened labiomental fold, recessive chin, and recessive and/or procumbent lower lip.
评估下巴畸形患者垂直性小颏畸形的治疗效果。
本回顾性研究纳入了21例患者。3位作者在学术或私人诊所环境中，对每位患者进行了带或不带植入物移植的颏部延长成形术。
主观分析表明，所有患者的下脸美观度均有显著改善。主观变化程度取决于畸形类型，是单纯垂直性小颏畸形还是合并矢状（水平）不足，以及唇颏沟的形态特征。未出现明显并发症。
对于面部下1/3高度垂直短小、唇颏沟加深、小颏畸形以及下唇后缩和/或前突的患者，应考虑进行颏部垂直延长术。
