The chin may be concerned by morphological abnormalities in its various dimensions. Classical genioplasty techniques can be used to correct these but have some disadvantages. The "chin wing", described by Triaca, is a technique of genioplasty extended to the mandibular angles, considering the mandibular basilar border as an anatomical unit, thus achieving a better harmonious functional and aesthetic result. The preoperative assessment included a mandibular Cone Beam to evaluate the position of the inferior alveolar nerve. The procedure was performed under general anesthesia. The periosteal dissection was limited to the osteotomy area and mental nerves were protected. The osteotomy observed a modification of its orientation in front of the mental foramen to become parallel to the basilar border, which was interrupted at the level of the mandibular angle. The spaces created were filled with bone grafts and maintained by a symphysary plate. Chin wing genioplasty both improves the function and aesthetic of the face because it considers the mandibular basilar border as an entire anatomical unit. It can be performed independently of any procedure to modify the bone bases. Nowadays, chin wing remains a challenging technique hardly performed.
颏部可能会因其各个维度的形态异常而受到影响。经典的颏成形术技术可以用来矫正这些问题，但也存在一些缺点。Triaca 描述的“颏翼”是一种颏成形术技术，扩展到下颌角，将下颌基底部视为一个解剖单位，从而达到更好的和谐功能和美学效果。术前评估包括下颌锥形束 CT 以评估下牙槽神经的位置。手术在全身麻醉下进行。骨膜剥离仅限于截骨区，并保护颏神经。截骨术观察到其在颏孔前方的方向发生改变，变得与基底部平行，并在下颌角水平处中断。用骨移植填充所产生的空间，并通过颏部固定板维持。颏翼成形术既改善了面部的功能，也改善了面部的美观，因为它将下颌基底部视为一个完整的解剖单位。它可以独立于任何修改骨基底的手术进行。如今，颏翼仍然是一种具有挑战性的技术，几乎没有人能够完成。
