The overlapping bone flap genioplasty is the transposition of the inferior part of the mandibular symphysis in front of the anterior mandibular cortex. The fragment remains attached to the medial fibres of the suprahyoid muscles. A study of long-term results (minimum 6 months) in 29 adults and 17 adolescents has shown a mean bone resorption of 24% in the first group, and 40% in the second group, with some unpredictable variations. The maximum resorption occurs between the 3rd and the 6th postoperative months and there is minimal change afterwards. The soft-tissue-osseous advancement is close to 75% in the adult and is comparable to the result of the standard sliding genioplasty.
重叠骨瓣颏成形术是将下颌骨联合前部在下颌骨前部皮质前方进行移位。骨块仍与舌骨上肌群的内侧纤维相连。一项对29名成年人和17名青少年的长期结果（至少6个月）研究表明，第一组平均骨吸收为24%，第二组为40%，且存在一些不可预测的变化。最大吸收发生在术后第3至6个月之间，之后变化极小。成人软组织 - 骨推进接近75%，与标准滑动颏成形术的结果相当。
