背景：亚洲人的面部特征是扁平或宽而圆。这些特征主要归因于颌骨的扩大和加宽，与咀嚼相关的令人印象深刻的肌肉，以及涉及咬肌的颧骨弓。他们的脸看起来是平的，中间的脸在中央回归。这种回归往往是结合狭窄的鼻唇角和一个沮丧的下颌骨基地和cheaks.Methods：1999年6月至2002年3月，32例患者进行了面部轮廓手术突出的下颌骨角和随后的鼻整形术。双侧下颌角肥大矫正后，使用矢状劈开角截骨术获得的骨段完成面中部增高。骨碎片通过口内入路插入鼻旁区，修剪，然后用骨凿重塑。结果：在这32例患者（31名女性和1名男性）中，47%的患者年龄在30多岁。术后评价的主要方面是正像上下颌角间距离的减少量、侧位上鼻旁区的突出程度和患者满意度。并发症包括1例伤口感染和2例伤口裂开。除两名患者外，所有患者均对结果感到满意。结论：下颌骨角度的一个阶段的修改和面中部区域的进步获得了满意的美学效果。优点包括没有任何额外费用和感染率低。自体移植没有任何缺点，并且手术产生了美学上优越的上级结果。作者提倡这种方法。
Background: Asians characteristically have flat or broad and round facial features. These characteristics are primarily attributable to enlarged and widened jawbones, impressive muscles associated with mastication, and a zygomatic arch involving the masseter. Their faces appear flat, with midface regression in the center. This regression is often combined with a narrow nasolabial angle and a depressed alar base and cheeks.Methods: Between June of 1999 and March of 2002, 32 patients underwent facial contouring surgery for prominent mandible angles and subsequent rhinoplasty. After bilateral prominent mandible angle modification, midface augmentation was accomplished using bony segments obtained from sagittal splitting angle ostectomy. The bony fragments were inserted via an intraoral approach into the paranasal area, trimmed, and then reshaped with an osteotome.Results: Of these 32 patients (31 women and one man), 47 percent were in their thirties. The amount of reduction of the distance between mandible angles on the frontal view, the extent of protrusion of the paranasal area on the profile view, and the degree of patient satisfaction were the primary areas of postoperative evaluation. Complications included one wound infection and two cases of wound dehiscence. All but two patients were satisfied with their results.Conclusions: Satisfactory aesthetic results were obtained with a one-stage modification of the mandible angles and advancement of the midfacial area. The advantages included the absence of any additional costs and a low infection rate. None of the disadvantages of an autologous transplant were present, and the procedure yielded aesthetically superior results. The authors advocate this method.
