The surgical approach to chin for esthetical purpose can be isolated or in a combination with other treatments like maxillomandibular surgery. Both possibilities include sliding genioplasty or implants of autologous or alloplastic materials. In this article, the authors present their new technique, the Pyramid Chin Augmentation.In January 2020, a 40-year-old male patient came to authors' observation asking for a great augmentation in the sagittal dimension of the chin, a better pronunciation of mandibular angles and of his cheekbones. The surgical treatment consisted in three different procedures at the same time: a chin wing osteotomy, a Pyramid Chin Augmentation and zygomatic PEEK custom-made malar implants. The pyramid was created on the body of the chin wing with a cortical bone graft from the oblique line of the ascending ramus of the mandible. The harvested bone was cut into strips of rectangular shape gradually shorter to be superimposed on the wing forming a pyramid. A fixation with 2 screws was performed and then was necessary to smoothen the edges of the bone layers.The result immediately after the end of the surgery was in line with the set goals. The mandibular angles were more prominent, the chin was more sagittal pronounced, and there was no evidence of depression in the symphysial region.The Pyramid Chin Augmentation Technique can be a valid tool in chin augmentation surgery and can also represent an effective procedure in the finishing touch of other facial surgery techniques.
出于美学目的的颏部手术方法可以单独进行，也可以与其他治疗方法（如上下颌骨手术）结合进行。这两种可能性都包括滑动下颌前徙术或自体或同种异体材料的植入物。在本文中，作者介绍了他们的新技术——金字塔颏部增强术。2020 年 1 月，一位 40 岁的男性患者来到作者处就诊，要求颏部矢状方向明显增大，下颌角和颧骨更好看。手术治疗包括三个不同的程序：颏翼部切开术、金字塔颏部增强术和颧骨 PEEK 定制颊部植入物。在颏翼部的体部上创建一个金字塔，用来自下颌升支斜嵴的皮质骨移植物。从升支斜嵴上切下的骨头被切成逐渐变短的矩形条，然后将其叠加在翼部上形成一个金字塔。用 2 颗螺钉固定，然后需要平滑骨层的边缘。手术后立即达到设定的目标。下颌角更突出，颏部更明显地呈矢状方向，颏前联合区没有凹陷的迹象。金字塔颏部增强技术可以是颏部增强手术的有效工具，也可以是其他面部手术技术完成阶段的有效方法。
