Angloplasty is the most common procedure in facial contouring surgery among Asians. However, to achieve satisfactory results during procedures aimed at altering the lower facial contour, the shape of the mandible and the chin area in particular is an important consideration. In cases of reoperation for further improvement after angloplasty, surgeons should consider performing a genioplasty to improve the shape of the chin.
From March of 2010 to August of 2012, 52 women who were dissatisfied with results of angloplasty and wanted a slimmer lower face underwent genioplasty and revision angloplasty. The procedures included narrowing genioplasty and contouring of the lower border of the mandible from the parasymphysis area to the previously resected area.
All patients were satisfied with their facial appearance, which had become slender when viewed from the front. There were no notable complications. No patient experienced permanent sensory numbness of the lower lip. Two patients complained of submental bulges and were treated postoperatively using laser-assisted liposuction.
When performing revision surgery to restore the contour of the mandible, the surgeon should consider the shape of the mandible as a whole to create a slender face, which is achievable by simultaneous narrowing genioplasty and contouring of the lower border of the mandible.
CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.
在亚洲人群的面部轮廓整形术中，截骨术最为常见。然而，在进行旨在改变下面部轮廓的手术时，特别是下颌和颏部的形状，是达到满意效果的重要考虑因素。对于因截骨术后效果不佳而需要进一步改善的再次手术，医生应考虑进行颏成形术来改善颏部的形状。
自 2010 年 3 月至 2012 年 8 月，52 名对截骨术后效果不满意且希望面部下部更显纤细的女性接受了颏成形术和修正性截骨术。手术包括缩窄颏成形术和从正中联合区域到先前切除区域的下颌骨下缘轮廓修整。
所有患者均对颏成形术后的面部外观感到满意，从正面看，面部变得更加纤细。无明显并发症。无患者出现下唇永久性感觉麻木。两名患者诉颏下隆起，术后采用激光辅助吸脂术治疗。
在行修复下颌骨轮廓的手术时，医生应整体考虑下颌骨的形状，通过同时进行缩窄颏成形术和下颌骨下缘轮廓修整来打造更显纤细的面容。
临床问题/证据水平：治疗性，IV 级。
