Without a doubt, the chin plays an important role on facial harmony. Both position and shape of the chin can significantly affect the facial profile. Genioplasty is a relatively simple surgical procedure that allows to correct deformities associated to the chin area. Several techniques and modifications have been described in the literature for different types of deformities. Anterior posterior reduction osteotomies of the chin have an unpredictable effect on the soft tissues and the use of the conventional sliding osteotomy have shown unsatisfactory cosmetic outcomes, this associated with step deformity, notching at the inferior border of the mandible among others. We propose a simple and effective technique that allows the correction of a chin deformity in cases where sagittal or vertical reduction is required with excellent esthetic results. Four case examples are presented for technique illustration.
毫无疑问，下巴在面部和谐中起着重要作用。下巴的位置和形状都能显著影响面部轮廓。颏成形术是一种相对简单的手术，可以矫正与下巴区域相关的畸形。文献中已经描述了几种用于不同类型畸形的技术和修改方法。颏部前后向骨切开术对软组织的影响不可预测，传统的滑动骨切开术显示出不满意的美容效果，其与台阶畸形、下颌下缘切迹等有关。我们提出了一种简单有效的技术，可在需要矢状或垂直减少的情况下矫正颏部畸形，且具有良好的美学效果。为了说明技术，我们呈现了四个病例示例。
