The aim of this review was to investigate the skeletal and soft tissue stability of isolated advancement genioplasty after more than 1 year, and to observe the influence of associated risk factors. A literature search was performed on PubMed, Web of Science, Embase, ScienceDirect, and Cochrane. Only studies with at least 10 patients who underwent an isolated advancement genioplasty, and with a follow-up period of at least 1 year, were included. Of the 2224 records initially identified, eight articles met the eligibility criteria. The mean age of the total study population was 23 years and ranged from 19.1 to 26.5 years in the individual studies. The average surgical advancement at pogonion was 8.2 mm and ranged from 6.2 to 11.7 mm in the individual studies. After 1 year, the horizontal hard tissue relapse at the level of pogonion varied from 0.1 to 2.1 mm. In two studies, this was reported as statistically significant. Regarding the soft tissue, the horizontal relapse varied from 0.3 to 2.9 mm, which was also considered statistically significant in two studies. Isolated advancement genioplasty was found to be a predictable and stable orthognathic procedure in the sagittal plane at both soft and hard tissue levels. The amount of relapse was not associated with the fixation method or with the amount of surgical advancement.
本综述旨在研究孤立性颏前徙术后 1 年以上的骨骼和软组织稳定性，并观察相关危险因素的影响。在 PubMed、Web of Science、Embase、ScienceDirect 和 Cochrane 上进行了文献检索。仅纳入了至少有 10 例接受孤立性颏前徙术且随访时间至少 1 年的研究。在最初确定的 2224 条记录中，有 8 篇文章符合纳入标准。总研究人群的平均年龄为 23 岁，各研究的年龄范围为 19.1 至 26.5 岁。在颏前徙术中，平均手术推进距离为 8.2mm，各研究的范围为 6.2 至 11.7mm。术后 1 年，在颏前点水平的硬组织水平复发率为 0.1 至 2.1mm。在两项研究中，这被报道为具有统计学意义。关于软组织，水平复发率为 0.3 至 2.9mm，在两项研究中也被认为具有统计学意义。孤立性颏前徙术在软硬组织水平上均为一种可预测且稳定的矢状骨面型手术。复发量与固定方法或手术推进量无关。
