A short and wide lower face is perceived as unattractive and masculine. Simply contouring the mandibular body and angle is insufficient to make the lower face with short and wide features slimmer and more feminine. In many cases, vertical elongation of the chin together with a bone graft is necessary. This can cause infection, donor-site morbidity and height loss by resorption of the grafted bone. To prevent this problem, the authors performed a pedicled interpositional graft with the discarded bone from narrowing genioplasty, and the results were aesthetically satisfactory.
From March 2010 to September 2011, 32 patients who received chin narrowing and vertical lengthening surgery at the authors' clinic were included in this study. For all the patients, the remnant mandibular bone at the stepoff from the site of the genioplasty to the mandibular angle was reduced concurrently.
No complications occurred, and all the patients were satisfied with their postoperative results.
Harmonizing the vertical length and transverse width of the chin is essential to acquiring more favorable results in mandibular contouring. The authors recommend pedicled interpositional bone grafting in narrowing genioplasty as a safe and useful method for aesthetic chin lengthening.

人们认为短宽型的下面部不美观，且具有男性化特征。单纯地对下颌体和下颌角进行轮廓塑形，对于改善短宽下面部的形态和使其更具女性化特征效果有限。在许多情况下，需要同时进行颏部的垂直延长和植骨，以改善短宽下面部。但这种方法可能会导致感染、供区并发症以及因移植骨吸收而导致的高度丢失。为了避免这些问题，作者采用废弃的下颌骨骨块行带蒂间置移植，以同期完成下颌缩窄和颏部垂直延长手术，获得了满意的美学效果。
自 2010 年 3 月至 2011 年 9 月，作者所在机构共对 32 例接受颏部缩窄和垂直延长手术的患者进行了回顾性研究。所有患者同时接受下颌骨截骨术，该截骨线位于颏成形术的截骨线与下颌角截骨线之间的台阶处。
所有患者均未出现并发症，对术后效果均表示满意。
颏部垂直长度和水平宽度的协调对于改善下颌轮廓的美学效果至关重要。在颏成形术中采用带蒂间置骨移植是一种安全有效的颏部延长方法。
