In East Asian countries, a prominent, long, and squared contour of the lower third of the face is considered unattractive, strong, and masculine. To change such a facial contour into an ovular contour, correction of the chin area is essential to accomplish the overall curve in the mandibuloplasty, and various methods for the horizontal reduction of the chin area have been suggested. The horizontal osteotomy and central strip resection technique, which is the most widely used method, has comparatively little effect and some restrictions. To improve these points, the authors introduced an effective method for simultaneously reducing the width and height of the chin without additional procedures.
From March 2010 to May 2013, 432 women and 117 men underwent mandibular contouring surgery. Of these patients, 321 needed correction of the chin shape with simultaneous mandibular contouring surgery. Narrowing and vertical reduction genioplasty was performed for these patients using an inverted V-shaped osteotomy with central bony segment resection.
Narrowing and vertical reduction genioplasty was successfully performed in all cases. No severe complications were observed. Transient sensory changes of the skin around the chin were observed in 87 patients, but all recovered within 3 months. All of the patients were satisfied with the results.
The method that we introduce in this article is a simple and more effective method for simultaneous reduction of the width and height of the chin without additional procedures. The square and long face was effectively and easily reshaped into a slender ovular contour, and the shape of the chin was changed from square to slender.
在东亚国家，面部下三分之一轮廓突出、长且呈方形被认为缺乏吸引力、显强硬且具男性化特征。为将这种面部轮廓转变为椭圆形轮廓，在进行下颌整形手术以实现整体曲线时，下巴区域的矫正至关重要，并且已经提出了多种水平缩小下巴区域的方法。水平截骨术和中央条带切除术是使用最广泛的方法，但效果相对较小且存在一些限制。为改善这些问题，作者引入了一种无需额外手术即可同时缩小下巴宽度和高度的有效方法。
2010年3月至2013年5月，432名女性和117名男性接受了下颌轮廓整形手术。在这些患者中，321名需要在进行下颌轮廓整形手术的同时矫正下巴形状。对这些患者采用倒V形截骨术并切除中央骨段进行缩窄和垂直缩小颏成形术。
所有病例均成功进行了缩窄和垂直缩小颏成形术。未观察到严重并发症。87名患者出现下巴周围皮肤短暂感觉改变，但均在3个月内恢复。所有患者对结果均满意。
本文介绍的方法是一种简单且更有效的方法，无需额外手术即可同时缩小下巴的宽度和高度。方形长脸可有效且轻松地重塑为细长的椭圆形轮廓，下巴形状从方形变为细长形。
