A square face is considered unattractive in Orientals; thus, it has become a frequently encountered reason for patients undergoing face contouring surgery. While reviewing the unsatisfactory cases of mandibular reduction, the authors discovered that some failed cases were related to a square jaw on a short face. The conventional procedures fix only the posterior region of the mandible, resulting in increased prominence of the stunted or square chin and short face. Thus, the authors applied a narrowing and sliding genioplasty procedure combined with a mandibular outer cortex ostectomy technique to reshape a wide, weak chin, and a square jaw on a short lower facial contour into a slender and attractive oval face.
From July of 2005 to October of 2009, there were a total of 57 patients in this study who underwent a narrowing and sliding genioplasty combined with a mandibular outer cortex ostectomy procedure to correct a square jaw on a short face.
The postoperative appearance of all 57 cases showed that the lower face had narrowed and had become softer, slender, and oval, with a slick mental region.
Narrowing and sliding genioplasty combined with a mandibular outer cortex ostectomy procedure could efficiently adjust the shape and position of the chin to obtain a good proportion of the lower face and change a square, short face to a slender, oval one in a single operation in accordance with fashionable aesthetics in Orientals.
在东方人看来，方形脸不美观；因此，脸型轮廓整形成为了患者常见的诉求之一。在回顾下颌缩小术的不满意病例时，作者发现有些失败的病例与短脸的方形下颌有关。传统的手术仅固定下颌的后区域，导致发育不良或方形的下巴和短脸更加突出。因此，作者应用了缩窄和滑动颏成形术，并结合下颌外皮质骨切除术，以重塑宽而弱的下巴和短脸的方形下颌，使其变成纤细而有吸引力的椭圆形脸。
2005 年 7 月至 2009 年 10 月，共有 57 例患者接受了缩窄和滑动颏成形术，并结合下颌外皮质骨切除术，以矫正短脸的方形下颌。
57 例患者的术后外观均显示，下面部变窄，颏部变得更加柔和、纤细、呈椭圆形，颏下区平滑。
缩窄和滑动颏成形术并结合下颌外皮质骨切除术，可以有效地调整颏部的形状和位置，使下面部获得良好的比例，并根据东方人的时尚审美，在一次手术中改变方形、短脸为纤细、椭圆形的脸型。
