Osseous genioplasty is a versatile technique to improve chin and facial aesthetics. It carries several benefits compared to an alloplastic implant, but the downsides of an intersegmental gap and lateral stepoffs must be weighed. These areas are typically left open, despite being subject to unpredictable resorption or incomplete osseous healing. We describe the strategy of using a combination of demineralized bone matrix (DBM) and fibrin glue to promote bone fill while smoothing contours and transitions along the genioplasty. Our retrospective study included 32 patients who underwent genioplasty with the DBM-fibrin sandwich. There were no genioplasty-related complications at the 6 months follow-up. Our results indicate that this technique is safe and is a valuable addition to possible graft material for genioplasty.

骨性颏成形术是一种改善颏部及面部美学的多功能技术。与异体植入物相比，它有诸多益处，但必须权衡节段间间隙和外侧台阶的缺点。尽管这些区域易发生不可预测的吸收或骨愈合不完全，但通常任其敞开。我们描述了使用脱矿骨基质（DBM）和纤维蛋白胶促进骨填充，同时使颏成形术轮廓和过渡更平滑的策略。我们的回顾性研究纳入了32例行DBM - 纤维蛋白夹层颏成形术的患者。在6个月随访时未出现与颏成形术相关的并发症。我们的结果表明，该技术是安全的，是颏成形术可能的移植材料中一项有价值的补充。
