This retrospective study compared genioplasty using Medpor with osteotomy by measuring the amount of anteroposterior change in hard and soft tissue.
Thirty-three patients who underwent mentum augmentation and who were followed-up >6 months were included. Subjects were divided into 2 groups: group A, with 14 patients who underwent genioplasty using osteotomy; and group B, with 19 patients who underwent genioplasty using Medpor. Patients chose one of the treatments themselves.
The mean relapse rate of the most prominent or anterior point on the chin in the midsagittal plane of patients who went underwent osteotomy was 18.59%, and the mean relapse rate of patients who went underwent genioplasty with Medpor was 14.56%.
It was found that the amount of the movement at the time of surgery when checked after surgery did not change in patients who underwent genioplasty using Medpor compared with patients who underwent genioplasty using osteotomy.
本回顾性研究通过测量硬组织和软组织前后变化量，比较使用Medpor进行颏成形术与截骨术的效果。
纳入33例行颏部增大术且随访时间超过6个月的患者。将受试者分为2组：A组，14例行截骨颏成形术的患者；B组，19例行Medpor颏成形术的患者。患者自行选择其中一种治疗方法。
接受截骨术的患者在矢状面中颏部最突出或最前点的平均复发率为18.59%，接受Medpor颏成形术的患者平均复发率为14.56%。
发现与接受截骨颏成形术的患者相比，接受Medpor颏成形术的患者术后复查时手术时的移动量未发生变化。
