The goal of mentoplasty is to improve chin projection. Traditionally, this is accomplished by either mandibular osteotomy or alloplastic implants. However, these procedures are not free of complications. This report describes gliding mentoplasty, a novel, simple technique for chin projection.
The 12 patients in this study underwent gliding mentoplasty. By means of a 2-cm intraoral incision, a subcutaneous dissection was made in the caudal direction. The dissection then proceeded in the subperiosteal plane, leaving a 1-cm cuff of muscle attached to the bone, and advanced toward the lower border of the chin. Subsequently, the dissection was extended laterally, and the whole mental area was dissected from the surrounding tissue. Three 2-0 monofilament nylon sutures were placed in the submandibular periosteum and connected through the remaining muscle cuff to the periosteum. These key sutures allowed the submandibular region to slide forward, project the subcutaneous tissue and mentalis muscle, define the labiomental fold, and improve the pogonion projection.
Gliding mentoplasty resulted in a symmetric projection of the chin in all cases. In two patients, a submandibular dimple developed, which spontaneously resolved in 1 month. No revision surgery was performed, and no tissue relapse was noted. The mean follow-up period was 24.7 ± 5.17 months (range 19-33 months). All the patients were satisfied with the result.
Gliding mentoplasty is a simple, easy-to-perform, rapid surgical technique of chin projection that produces low pain, rapid recovery, and excellent cosmetic results.

隆颏术的目的是改善颏部的突出度。传统上，这可以通过下颌骨截骨术或假体植入来实现。然而，这些手术并非没有并发症。本报告描述了滑行隆颏术，这是一种新颖的、简单的颏部突出术。
本研究中的 12 例患者接受了滑行隆颏术。通过 2cm 的口内切口，在颏部下方向下进行皮下剥离。然后在骨膜下平面进行剥离，留下附着在骨上的 1cm 宽的肌肉袖，向颏部下缘推进。随后，将剥离向外侧扩展，将整个颏部从周围组织中分离出来。在下颌骨骨膜上放置 3 根 2-0 单丝尼龙缝线，并通过剩余的肌肉袖将缝线连接到骨膜上。这些关键缝线允许下颌区域向前滑动，突出皮下组织和颏舌肌，定义唇颏沟，并改善颏顶点的突出度。
滑行隆颏术使所有病例的颏部都呈现出对称的突出度。在 2 例患者中，出现了颏下凹陷，1 个月后自行缓解。未行修正手术，也未发现组织复发。平均随访时间为 24.7±5.17 个月（19-33 个月）。所有患者对结果均满意。
滑行隆颏术是一种简单、易于操作、快速的颏部突出术，疼痛低、恢复快、美容效果好。
