The facial skeleton is foundational for facial aesthetics. The authors describe an alternative technique for cosmetic chin augmentation that does not require alloplastic implants, osseous genioplasty, or autologous bone harvesting. In this new and innovative technique for chin augmentation, tissue bank allograft cancellous bone chips serve as a scaffold for bony ingrowth. The use of bone chips allows for aesthetic contouring with small adjustments in the facial skeleton. The objective of this article is to provide further information on this novel technique and demonstrate the efficacy and safety of tissue bank allograft cancellous bone chips as an alternative graft material for cosmetic chin augmentation. Retrospective review of patients who underwent chin augmentation with cancellous bone chips from July of 2015 to March of 2019 was performed. Photographic results from several patients are included. No patients developed infections, required reoperation, or went on to have explantation of the graft material. Initial results suggest cancellous bone chips are a safe, efficacious alternative graft material for cosmetic chin augmentation.
CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.
面颅骨是面部美学的基础。作者描述了一种用于美容隆颏的替代技术，该技术不需要使用任何形式的假体植入物、颏骨整形术或自体骨采集。在这种新的、创新的隆颏技术中，组织库同种异体松质骨骨屑作为骨内生长的支架。骨屑的使用允许对面部骨骼进行微小调整，以达到美学轮廓。本文的目的是提供关于这种新技术的更多信息，并展示组织库同种异体松质骨骨屑作为美容隆颏替代移植物材料的疗效和安全性。对 2015 年 7 月至 2019 年 3 月期间接受松质骨骨屑隆颏术的患者进行了回顾性研究。包括了几位患者的照片结果。没有患者发生感染、需要再次手术或移植材料被取出。初步结果表明，松质骨骨屑是一种安全、有效的美容隆颏替代移植物材料。
临床问题/证据水平：治疗，IV 级。
