Mentoplasty with Cancellous Bone Chip Scaffolding: An Innovative Technique for Chin Aesthetics.

SUMMARY: 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.
