Prominent zygoma is commonly seen in the East Asian population with the clinical characteristics of anteriorly and/or laterally projected zygoma and zygomatic arch resulting in an increased midfacial width. The esthetic surgical modification of zygoma is one of the major aspects of facial-contouring surgery in certain parts of the world. This article aims to evaluate the effectiveness of various surgical methods for reducing the prominent zygoma so as to obtain a harmonious and natural facial contour.
Surgical approaches, such as zygomatic complex shaving, I-shaped osteotomy, L-shaped osteotomy, and C-shaped osteotomy were used according to the clinical characteristics of zygoma and zygomatic arch protrusion. The corrective effectiveness was then evaluated through cephalometric radiographs, 3D-CT, and pre- and postsurgical standard facial photographs.
The zygoma and zygomatic arch protrusion was effectively corrected resulting in improved facial contours in all cases postoperatively. The postoperative period was uneventful except for the slight limitation in mouth opening, which recovered fully after mouth-opening exercises. Serious complications, such as facial nerve injury, were not witnessed in our study.
Malar reduction is an effective and a safe method for the treatment of prominent zygoma. The selection of surgical procedure should be based on different presenting characteristics of zygoma and zygomatic arch protrusion. The correction of prominent zygoma should be designed well, performed precisely, and observed carefully to avoid severe complications so as to achieve a harmonious facial contour.
颧骨突出在东亚人群中较为常见，其临床特征为颧骨和颧弓向前和/或向外侧突出，导致面中部宽度增加。颧骨的美容手术矫正，是世界某些地区面部轮廓整形手术的主要方面之一。本文旨在评估各种手术方法减少突出颧骨的有效性，以获得和谐自然的面部轮廓。
根据颧骨和颧弓突出的临床特征，采用颧骨复合体磨削术、I形截骨术、L形截骨术和C形截骨术等手术方法。然后通过头颅侧位片、三维CT以及术前和术后标准面部照片评估矫正效果。
所有病例术后颧骨和颧弓突出均得到有效矫正，面部轮廓得到改善。术后除张口略有受限外，恢复顺利，经张口练习后完全恢复。本研究未观察到面神经损伤等严重并发症。
颧骨降低术是治疗颧骨突出的一种有效且安全的方法。手术方式的选择应基于颧骨和颧弓突出的不同表现特征。颧骨突出的矫正应精心设计、精确操作并仔细观察，以避免严重并发症，从而实现和谐的面部轮廓。
